Description
Technical field
The present invention relates to a kind of electric switchgear, comprise: housing with vertical geometric reference plane, be arranged in the pair of separable electrical contact in the open volume, towards the open arc chute of described open volume, described arc chute can sketch the contours by two parallel side walls that are placed on each side of geometric reference plane, rear wall, diapire and the roof of locating away from described open volume.Described arc chute comprises piling up of at least two deionization fins that separate each other by swapace, and each fin has design and is used for being exposed to leading edge under the electric arc.At least one swapace is removed the hole via at least one and is connected at least one removal pipe.
Background technology
The inner electric leakage that exists of switching device such as circuit-breaker, switch or contactor causes its electrical contact to disconnect at a high speed.This high-speed separation of contact is accompanied by the generation of electric arc usually.The energy of electric arc and the gas release of following described electric arc to take place produce big stress and damage described device easily at described mechanism place.
For thereby the time that reduces the short circuit appearance also reduces the thermal stress that electric switchgear bears, arcing voltage is increased as quickly as possible up to it to become greater than applied voltage.This causes short circuit current to be cancelled.Then, the dielectric resistance of air can prevent backfire or other starting the arc between separate contacts.
Electric arc must fast as far as possible cooling be kept away from electrical contact simultaneously.This cooling realizes by electric arc is placed in the arc chute that usually described arc chute comprises a folded metallic plate, is referred to as the fin that deionizes.In fact, just the electric arc that produces since the electric power that bring out in the magnetic field that the electric current that flows in the conductor produces be pushed in the arc chute.
When electric arc was moved, the latter was tending towards between the sidewall of arc chute usually the path movement of the recess that exists in fin.These recesses have encouraged electric arc moving to the arc chute bottom.In addition, piling up of fin makes electric arc be disintegrated and make things convenient for their insertions in arc chute.During whole opening circuit, fin provides exchange surface for electric arc.When electric arc advances in the arc chute, thereby it is tending towards expanding and pours in whole free space.Interact by the periphery with electric arc, fin can comprise this expansion.When electric arc cooled off, arcing voltage increased.In addition, the pressure that opens circuit in the volume increases greatly.
If the shape of recess is not optimized, may electric arc take place repeatedly and strike sparks again between contact.
Some document (FR2,839,195) discloses the recess that stops by the chimney-like ventilation hole, and it is tending towards stable arc in away from the zone of contact open volume.Yet the shape of recess is characterized in that existing from electric arc producing the passage of distinguishing the chimney-like ventilation hole, can produce hot gas and the steam that is sent to the unlimited district of contact direction and therefore cause electric arc to be leaked to contact from arc chute.This leakage is accompanied by sparking again repeatedly.
In addition, simultaneously, the generation of electric arc causes the generation of a large amount of metal vaporss or gas, if their not removed words, they may cause the link electric arc between the electric switchgear phase place especially and produce blast.
Numerous existing solutions provides at least one to be used for described gas is driven away near the pipe outside the zone of contact.These gases are dispersed outside the electric switchgear usually.
Though these solutions provide some advantages, yet they have the risk that produces public hazards in the place of placing switching device.In fact, when these gases also heat during with high ionization, they can produce harmful result.
In order to prevent to pollute external environment condition, other solutions have proposed internal gas recirculation (GB2,285,889, US5,731,561 and FR1,400,079).
There is some shortcoming in these solutions.This internal gas recirculation is accompanied by the increase of electric switchgear volume usually.In fact, gas is directed in the designated volume of locating above arc chute usually.In addition, be used for the pipe of guiding gas, because their geometry can be brought out the pressure trap, the removal that this pressure trap can cause described gas is bad or slow down.

According to first preferred embodiment shown in Fig. 1,2 and 3, this electric switchgear 30 comprises the housing of being made by molded plastic material 31, has arranged at least one stationary contacts 32 that is associated with at least one movable contact 33 in this housing.One or more fault-locating unit especially for the fault-locating unit that short circuit is surveyed, act on the actuating mechanism 34 of control movable contact 33 unlatchings.
This housing 31 is because its shape forms vertical geometric reference plane xz.
In the embodiment shown in this, electric switchgear comprises two U type stationary contacts 32 that are connected respectively to electric connection terminal.The movable contact 33 of effect translation that can be by actuating device 34 can be electrically connected to two stationary contacts 32.Movable contact 33 has two contact zones 36, and each contact zone can be cooperated with stationary contacts 32 respectively.Therefore, corresponding with the space of the contact zone 36 of arranging stationary contacts 32 and being associated with movable contact 33, form two open volume 35.
In addition, each open volume 35 all is associated with arc chute 10.Can sketch the contours by two parallel side walls 11 that are placed on vertical geometric reference plane each side of xz, rear wall 6, diapire 7 and the roof 8 of locating towards open volume 35 open arc chutes 10 away from open volume 35.
Each fin 1 comprises that design is used for being exposed to the free leading edge 5 of electric arc.This free leading edge 5 preferably forms open recess 9, and the front surface of this recess along the direction of the longitudinal axis 12 from arc chute 10 extends to rear wall 6.This recess 9 is sketched the contours of two lateral branching 1a, 1b.
The recess 9 of at least two fins 1 is symmetric shape and comprises two parts.It comprises that facing first conical forward portion that is placed on the contact 32,33 in the open volume 35 divides 9a and second narrower vertical rear section 9b.
According to a preferred embodiment of the invention, shown in Fig. 6 A and 7A, the leading edge 5 that extends along the flat surfaces of described at least two fins contacts twice at an a, b place at least with the longitudinal axis 12 of this fin.In other preferred embodiments of the present invention, shown in Fig. 4 A and 5A, leading edge 5 is the longitudinal axis of selecting described at least two fins of a, b, c place cutting 12 3 times.
According to these preferred embodiments of the present invention, recess 9 is realized in such a way, promptly, when two fins are staggeredly stacked, along the z axle at the lateral branching 1a of first fin 1 with place between at least one lateral branching 1a of second fin 1 of intervening portion and have at least two aligned region a and b.When fin when its longitudinal axis 12 Rotate 180s are spent, fin is in intervening portion with respect to another fin.First aligned region is preferably located among the forward part 13a of fin 1.
When the leading edge 5 three times cutting longitudinal axis 12, at the lateral branching 1a of first fin 1 with place between at least one lateral branching 1a of second fin 1 of intervening portion and have three aligned region a, b and c.Then, the overlay region 50 that has lateral branching 1a.Each fin all comprises overlay region 50, and this overlay region can be sketched the contours by the intersection point between the leading edge 5 of an a and the b place longitudinal axis 12 and the first lateral branching 1a.
According to these two preferred embodiments of the present invention, described two lateral branching 1a, 1b are located substantially on each side and first conical forward portion of the described longitudinal axis 12 and divide 9a to be cut by the longitudinal axis 12.
In the embodiment shown in Fig. 1-11, all fins that are placed in the arc chute 10 comprise identical recess 9.Piling up with such method of this group fin of arc chute 10 forms, and promptly at least two fins are staggeredly stacked, so the shape of their recess 9 is inconsistent.
Preferably, all fins 1 all are staggeredly stacked, so each fin 1 is near another fin location about its longitudinal axis 12 Rotate 180 degree.
Because the asymmetric shape of fin 1 recess 9 and with the described fin that interlace mode piles up has formed the ventilation hole 15 of chimney-like, its air channel is closed in the plane xy vertical with described chimney-like ventilation hole 15 longitudinal axis 16 substantially.
In this embodiment, chimney-like ventilation hole 15 from diapire 8 to roof the 7 whole height that extend across arc chute.
According to the shape of the recess 9 of fin 1, the axis 16 of chimney-like ventilation hole 15 will be more or less near the rear wall 6 of arc chute 10.Preferably, chimney-like ventilation hole 15 is positioned at jack shaft 13 places of fin 1 or surpasses described axis towards rear wall 6.
Fin is made by the electric conducting material based on steel.The deionization fin 1 that piles up each other separates each other by swapace 2.The thickness of each swapace 2 is less times greater than the thickness of fin.
Gas that occurs in arc chute 10 or metal vapors are removed by at least one the removal pipe that is connected to one or more swapaces 2 via the removal hole in a conventional manner.Gas can be dispersed the electric switchgear outside, but has the risk that produces public hazards in the place of placing switching device.
In certain embodiments of the invention, using gases EGR subsequently.At least one swapace 2 is removed hole 4 via at least one and is connected at least one removal pipe 3.Described at least one removal pipe 3 design on the one hand is used for removing gases from arc chute 10, is used on the other hand via contact 32, the 33 place injecting gas of opening 18 in open volume 35.In addition, described at least one removal pipe 3 is removed hole 4 along at least one sidewall 11 from least one and is extended to opening 18.Described opening 18 is placed towards the electrical contact 32,33 of open volume 35.
Then, gas flow is passed by at least one and is removed the effuser that hole 4, at least one removal pipe 3 and at least one opening 18 constitute.Described removal pipe 3 has cross section A constant or that increase on their whole length and along the x axle.In addition, preferably, described removal pipe 3 also has constant cross section along y axle and z axle.In other words, the cross section of described pipe all is constant from the inlet of gas to outlet basically.Preferably, the cross section of described pipe can increase.Then, opening 18 equals the maximum cross section A of described pipe at least.
Usually, the cross section of accepting the effuser of gas must keep constant at least or increase.Therefore this geometrical property has strengthened the gas flow from swapace 2, and has limited the generation of the pressure trap (pressure trap) that may form along effuser.Reducing of described effuser cross section particularly removing pipe 3 or opening 18 places, may cause the generation of pressure trap.These pressure traps can make advancing of gas and advancing of electric arc slow down.
Preferably, in the preferred embodiment of the present invention shown in Fig. 1-3, each swapace 2 is removed hole 4 via at least one and is connected at least one removal pipe 3.The shape and size of removing hole 4 are for like this, and promptly air-flow can not make electric arc pass through these holes.For fear of between the fin 1 because electric arc and short circuit, remove the hole and form and be not communicated with each other in mode independently.
Preferably, exist at least two to remove pipe 3, so at least one pipe 3 is along each sidewall 11 extensions of arc chute 10.In the embodiment shown in Fig. 1 and 2, each of placing near sidewall 11 removed pipe from removing hole 4 to opening 18, from diapire 8 to roof 7 and extend along sidewall 11.
Shown in Fig. 1-3 according to a preferred embodiment of the invention in, used two to remove pipe 3.Remove each sidewall 11 placements that pipe 3 approaches arc chute 10 for one.Each swapace 2 comprises that at least one is connected to the removal hole 4 of removing pipe 3.The removal hole 4 that is placed in the sidewall 11 is positioned in the zone that comprises between the jack shaft 13 of rear wall 6 and fin 1.In addition, these pipes are cuboid (parallelepipedic) shape substantially.
Switching device is operated in the following manner.When short circuit takes place, because the electromagnetic field of the current induced that flows in the conductor, particularly at stationary contacts 32 places, produce in movable contact 33 movable contact is repelled the electric power of separation point position, this motion can be confirmed by opening actuating mechanism via mechanism 34 subsequently.When the firm generation of the separation of contact 32,33, will between described contact, produce electric arc.This electric arc is pushed into arc chute 10 by electric power.Move in the process of chimney-like ventilation hole 15 and rear wall 6 at it, electric arc remains on the intermediate distance between each sidewall 11, because it is tending towards passing the opening recess 9 between fin.
In addition, set up gaseous exchange, so electric arc can not increased obstruction by pressure towards advancing of rear wall 6 via removing pipe 3.Before movable contact 33 had arrived its final separation point position, the electric arc pin was moved to chimney-like ventilation hole 15 from stationary contacts 32 rapidly.
Gas that in fact, send around electric arc and that exist in swapace 2 is via comprising that the effuser of removing hole 4, removing pipe 3 and opening 18 is injected into open volume 35.By effuser remove uniformly and the gas of regular distribution reduced the risk of pressure trap, this pressure trap is the reason that causes gas to advance and advance and slow down with electric arc.Local pressure in electric arc the place ahead increases or in fact the existence of refrigerating gas has caused moving of electric arc to be slowed down.
The gas flow of direction in effuser along the electrical contact 32,33 of open volume 35 makes the gas of described compression be depressurized and cooling faster.
The injection that is present in the refrigerating gas at contact 32,33 places in the open volume 35 has increased the dielectric strength in this space and has therefore prevented the public hazards that electric arc is struck sparks again.In addition, this injection at the contact place makes open volume 35 plasma occur, and arc chute 10 will bear cooling and backflow weakly ionized gas.This makes the rear area of electric arc be cooled but has also caused hot gas to be sent to the place ahead of electric arc.Because electric arc cools off via the rear, therefore, electric arc is tending towards development in face of the heat of ionization gas that is associated with metal vapors, moves and therefore move away from the open zone of contact towards the rear side 6 of arc chute 10.
According to the alternate embodiments of first series, shown in Fig. 6 A and 7A, leading edge 5 extends along the flat surfaces of fin 1, and the recess 9 of the asymmetric shape that forms is being selected the longitudinal axis 12 that described fin is cut at a, b, c, d, e place for five times.Because the asymmetric shape of recess 9 and being staggeredly stacked of described fin of each fin 1 form two chimney-like ventilation holes 15, its air channel 16 is closed in the plane xy vertical with described chimney-like ventilation hole 15 longitudinal axis 16 respectively substantially.
According to the alternate embodiments of second series, shown in Figure 10 A and 10B, leading edge 5 advances along the flat surfaces of fin, and the longitudinal axis 12 of the described fin of recess 9 cutting twice of the asymmetric shape that forms.In addition, the first longitudinal component 9a that is tapered locatees to such an extent that surpass the longitudinal axis 12 of fin 1.
In another alternate embodiments shown in Figure 11, swapace 2 comprise at least one be placed in the rear wall 6 and with remove the pipe 3 removal holes 4 that are connected.According to this embodiment, each swapace 2 comprises that two are removed hole 4; Each hole is connected respectively to removes pipe 3.
In another alternate embodiments, each hole 4 is connected to opening 18 in spontaneous mode via itself removal pipe 3.In fact, each is removed pipe 3 and guarantees with other removals and hold independence.
