Abstract
The aim of the invention is to create an arc quenching system for a switching device, which ensures low heat build-up and fast quenching of an arc using simple means. Said aim is achieved by providing a current conducting path which comprises an electrically conducting passage to an additional arc guide rail so as to form a conductor loop and is electrically insulated relative to a pair of switching contacts. The conductor loop is not connected to the pair of switching contacts while being arranged in the area of an interrupter chamber such that a current (I) which drives the arc into the arcing chamber is conducted via the current conducting path when the arc commutates from one of the switching contacts to the additional arc guide rail.

Description of drawings
Embodiment shown in reference to the accompanying drawings is described further the present invention and the favorable characteristics that meets the described feature of other claims below, but the present invention is not limited to described embodiment, wherein:
Fig. 1 is a section of a switchgear, and described switchgear has switch contact and described arc control device of claim 1 of a pair of closure; And
Fig. 2 is a section of switchgear shown in Figure 1, and described switchgear has the switch contact of a pair of disconnection.
Embodiment
What Fig. 1 showed is a section that has the switchgear 1 of an arc-control device, described switchgear have one this sentence the outer cover 2 that schematic form is represented.In this embodiment, switchgear 1 is embodied as a line protection switch, and except that a magnetictrip 3, it also has a thermal overload release 4 and a pair of switch contact that comprises a fixed contact 5 and a moving contact 6.Fixed contact 5 is fixed on one and plays the leading on the arc track 7 of contact base effect, and the described arc track of leading also with between the coil of magnetictrip 3 exists a conduction to be connected simultaneously.Described coil itself lead to one this sentence the binding post that schematic form is represented.The free end of leading arc track 7 feeds in the arc control device 8 after through an adjacent yoke.This part fixed contact 5 back, that lead to arc control device 8 is led arc track 7 and is embodied as ear shape structure.Moving contact 6 is fixed on the movable contact arm 9, and described contact arm is bearing on the axle of not doing among the figure to show, and can rotate around it.Magnetictrip 3 and thermal overload release 4 (being a bimetallic release in this embodiment) can cause the skew of movable contact arm 9 according to different failure conditions.
Except that leading arc track 7, also be provided with one and lead arc track 10 with second of its existence one determining deviation, lead the arc track and in its free end zone, comprise arc control device 8 for described these two.These two the arc tracks 7,10 of leading that are that funnel-form arranges play jointly an electric arc 11 (Fig. 2) are imported effect in the arc control device 8 that receive this electric arc 11 motivatedly.Enter the zone of defining in the district by switch contact 5,6 and described two electric arcs of leading arc track 7,10 and arc control device 8 and be called blocking-up chamber or cup 12.Blocking-up chamber 12 has a conductive path 13, and this conductive path has one first subregion 13a, second a subregion 13b and one the 3rd subregion 13c.Conductive path 13 has one and leads to second and lead the conductive channel of arc track 10 in its first subregion 13a, thereby constitutes a conductor circuit 10,13.Conductor circuit 10,13 all is complementary with the appearance profile of blocking chamber 12 on shape and position, thereby can partly place the back of arc control device 8 by the described second subregion 13b.Except common used materials such as copper, aluminium and steel, conductor circuit 10,13 also may be embodied as sheet metal bending part, flat bool or wire molded part.
Conductor circuit 10,13 is connected on the conductive channel shown in Figure 1 by a kind of common joint technology, but described passage also may be embodied as an integral body.Conductor circuit 10,13 projects under connectionless state in the zone of switch contact 5,6, so-called " do not have and connect " is meant that conductor circuit 10,13 does not all contact with leading between arc track 7 or movable contact arm 9 and the top contact 5 or 6 thereof.Conductor circuit 10,13 is also not contact on its crosspoint.In the case, from the figure cut-layer(s) of Fig. 1, extend in the back of switch contact 5,6 as the conductive path 13 of the part of conductor circuit 10,13.Certainly, also can lead such conductive path 13 of layout on the arc track 10 in the both sides of switch contact 5,6 second simultaneously.Shown in the configuration that dots among Fig. 1, additional conductive path extends above switch contact 5,6 from the figure cut-layer(s).In addition, also can take a kind of like this embodiment, promptly arrange a complete conductor circuit 10,13 respectively in the both sides of switch contact 5,6.These two conductor circuits 10,13 are electrically connected at an end place, loop of leading to another binding post.
In Fig. 1, the electric current I of representing with an arrow enters described switchgear from binding post.Electric current I flows through the coil of magnetictrip 3 and leads the contact zone of the part back arrival switch contact 5,6 of arc track 7, and lead to final another binding post that arrives behind the twisted wire of thermal overload release 4 here from begin to flow through activity contact arm 9 and one, can connect a power consumption equipment on this binding post.When switchgear 1 is in normal operating conditions, just when switch contact 5,6 is in closure state, the described electric current conductor circuit 10,13 of not flowing through, thereby, the favourable aspect such as internal resistance is little short except current circuit, the power consumption of switchgear 1 is also very little.Except that line protection switch, switchgear 1 also may be embodied as for example mains switch or contactor.
What Fig. 2 showed is a section of switchgear 1 shown in Figure 1, and described switchgear has the switch contact of a pair of disconnection.A corresponding dropout situation or the failure condition that short circuit current or overload current have occurred of the contact position here.The mobility status of described electric current before arriving switch contact 5,6 is with shown in Figure 1 consistent.When contact 5,6 was separated from one another, described electric current flowed in a corresponding contact zone that diminishes gradually, makes that the temperature on this zone raises gradually.Before separating, described contact 5,6 can produce a molten bridge in a flash, electric current hour, and molten bridge finally can be broken; When electric current was big, molten bridge will evaporate.Therefore, electric current I can only continue to flow by the electric arc 11 that occurs with a conductive plasma cylindricality formula.
When the movable contact arm 9 that has moving contact 6 separates gradually with fixed contact 5, described electric arc is to avoid being broken and the stretching phenomenon that produces owing to its combustion characteristics is made when antagonism, described electric arc 11 will commutate, promptly commutate to conductor circuit 10,13, especially commutate to second and lead arc track 10 (shown in bent arrow) from moving contact 6.At this moment, described electric arc can be followed physical principle and select the path of resistance minimum, and on the current potential of the conductor circuit 10,13 that jumps.Be furnished with one on the conductive path 13 and be used to prevent that electric arc 11 from commutating to the insulating part of conductive path 13 from moving contact 6, the insulating trip 14 for example illustrated in figures 1 and 2 or case member of insulating effect is arranged.Insulating trip 14 mainly extends on the first and second subregion 13a, 13b.In case of necessity, insulating trip 14 can extend on the 3rd subregion 13c of conductive path 13 always.Also can arrange that a covering, this obducent effect are to make electric arc move on to the conductive channel next door earlier leading the conductive channel that arc track 10 leads to conductive path 13, and then move on to second and lead on the arc track 10 from second.According to the present invention, also can on described additional conductive path, arrange described insulating part.
Finish commutation back at electric arc 11 but still be in several milliseconds of times of its burning sustained period, conductor circuit 10,13 is connected in two current circuits between the binding post.Therefore, the total current I that is caused by overload or short circuit can flow through conductor circuit 10,13 earlier after ARC commutating finishes.Can significantly reduce the intensification degree of switchgear 1 thus, thus can be in the requirement that reduces aspect the compensation self-heating thermal overload release 4.In this case, use the lower material of conductivity, for example make conductor circuit 10,13 and also can play the effect of saving cost with the steel Alloy instead of Copper.
Because conductor circuit 10,13 is arranged in the zone of blocking-up chamber 12 substantially, when magnetic field took place to focus on or turns to, electric arc 11 can be subjected to the influence of magnetic effect.The sense of current in the first subregion 13a of conductor circuit 10,13 and the current opposite in direction of electric arc 11.Reverse current---refers to the electric arc 11 and the first subregion 13a here---and has the magnetic field of mutual repulsion, and, thereby be in two electric arcs 11 of leading between the arc track 7,10 and can be pushed to arc control device 8 because conductor circuit 10,13 is embodied as fixingly and resistant to bending.In addition, the sense of current in the second subregion 13b of conductor circuit 10,13 is identical with the sense of current of electric arc 11.Current---refers to the electric arc 11 and the second subregion 13b here---and has the magnetic field that attracts each other in the same way, and, thereby be in two electric arcs 11 of leading between the arc track 7,10 and can be attracted to arc control device 8 because conductor circuit 10,13 is embodied as fixingly and resistant to bending.
This effect that is subregion 13a that arch arranges and the caused power F of 13b is created in behind the ARC commutating in a flash.Wherein, except that repulsive force, electric arc 11 also is subjected to the effect of gravitation, and the intrinsic power one that this gravitation and electric arc produce betwixt works, and forces electric arc towards the motion of arc control device direction, impels it to enter arc control device rapidly, thereby reaches the purpose of rapid extinguish arcs.Because total overload current or total short circuit current finally by the 3rd subregion 13c arrive the conductor circuit 10,13 of flowing through before being connected second power consumption equipment (not shown) on the binding post at it, thereby the athletic meeting of electric arc 11 takes place significantly to quicken.Fault current is big more, and the urging force that electric arc is subjected to is also just big more.In this process,, high internal resistance and high current limliting have also been produced along with the quite formation of long current circuit; Switchgear 1, especially the make-break capacity of protection switch equipment increases.
Above-mentioned description of the present invention may be summarized to be:
The purpose of this invention is to provide a kind of arc-control device that is used for a switchgear 1, described arc-control device is guaranteed under low self-heating situation extinguish arcs rapidly by simple member.This purpose is reached by a conductive path 13 is provided, and described conductive path has one and leads to second and lead the conductive channel of arc track 10, thereby constitutes a conductor circuit 10,13, described conductive path and pair of switches contact 5,6 electric insulations.Be not connected between conductor circuit 10,13 and the switch contact 5,6, conductor circuit 10,13 is arranged in the zone of a blocking-up chamber 12, like this, when electric arc 11 from described switch contact 5,6 commutates to second when leading on the arc track 10, just can order about electric arc 11 and enter electric current I in the arc control device 8 by conductive path 13 one of conduction.
