The ring main unit load switch used at present, its arc quenching method use simple lattice hydrant arc extinguishing mostly, its arc extinguishing is former
Reason is：On-load switch can produce very strong arc light when cut-offfing 630A rated current, and arc light, which be easy to cause phase and phase short circuit, to be caused
Moment produces substantial amounts of heat, and the insulating gas being sealed in Stainless Steel Shell causes switch to explode, leads by transient heating expansion
Cause equipment damage.In addition arc light can cause the scaling loss of conductive component, such as conductive electrode contact, busbar contact, so as to be negative
The electric conductivity degradation of lotus switch, further increases the danger of on-load switch operation.Therefore, the arc extinguishing energy of on-load switch
Power is the very important technical parameter of ring main unit.The arc quenching method of original on-load switch is by arc extinguishing latch plate handle when arc light produces
Arc light elongate, make arc column by short and slightly become growth and it is thin, be a kind of passive type arc quenching method, arc quenching effect is not highly desirable.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of interrupter cartridge on ring main unit
Put and its arc-suppressing method, for improving the arc extinguishing ability of on-load switch, arc extinguishing is made into by original passive type arc extinguishing active
Magnetic quenching mode.
The purpose of the present invention is come what is completed, this arc-control device on ring main unit includes by following technical solution
On-load switch, Petersen coil, arc extinguishing stent, busbar connection row, busbar connection row are separately fixed at the ABC of on-load switch
On three-phase guide post, and the contact head of busbar connection row is connected with the busbar contact on on-load switch, and the arc extinguishing stent is consolidated
It is scheduled on busbar connection row, Petersen coil is installed on the arc extinguishing stent；It is provided with the Petersen coil and opens load
Close the target seeker that arc light caused by separating brake introduces Petersen coil.
Preferably, the target seeker of the Petersen coil is opened toward the busbar contact on on-load switch, and with load
In 130 ° of distributions between the busbar contact shut.
Preferably, the distance between busbar contact on the target seeker and on-load switch of the Petersen coil is less than
3MM。
Preferably, being provided with three through holes on the arc extinguishing stent, one of through hole is located at a left side for arc extinguishing stent
Side, another two through hole are located at the right side of arc extinguishing stent.
Preferably, the structure of the busbar connection row is bending-like.
Preferably, the material used in the busbar connection row is copper.
A kind of arc-suppressing method using the as described above arc-control device being used on ring main unit, the arc-suppressing method is by load
Switch arc light caused by separating brake and Petersen coil is introduced by target seeker, arc light is to enter Petersen coil in the form of electric current, is had
Electric current is rotated by that will produce magnetic field, and in the magnetic field high speed of Petersen coil, is drawn and attenuated so that arc light is elongated, energy is drastically
It is decreased until and is wholly absent, has the function that fast arc extinction.
Beneficial effects of the present invention are：New Petersen coil and the distinctive mounting means of Petersen coil are employed, is used for
Improve the arc extinguishing ability of on-load switch；New arc-suppressing method is employed at the same time, arc extinguishing is made into by original passive type arc extinguishing
Active magnetic quenching mode；The connecting-disconnecting function of on-load switch and stability are improved by increased arc-control device,
Strengthen the security reliability of the long-term actual motion of on-load switch.
