During touch and separate, from small to large, in the presence of high voltage, the insulation in gap is situated between in the gap between two contacts head
Matter can be ionized and puncture, and form electric arc, and after electric arc is formed, the heat of generation can be further exacerbated by medium ionization, expand electric arc, make
Breaker cannot disconnecting circuit, in order to prevent this process, when breaker is designed, two contacts mounted in an arc extinguishing
, there are many passages interior inside arc-chutes, one is subdividing the arc, and two is the high pressure draught produced using high arc temperature, by going out
The certain channel nozzle of arc chamber blows out electric arc.Therefore, using above-mentioned this connected mode, during use, easily send out
Raw spring, and clashed into, the connection being easily caused after such long-time use between arc-chutes and flange occurs to damage, breaks
Split, influence is normally used.
Utility model content

Binding structure, its innovative point is：The attachment structure is used to connect arc-chutes and flange, including
One connection unit, the connection unit includes the connecting bolt group of connection arc-chutes end and flange, the connection
Bolt group include several connecting bolts along circumference of flange directional spreding and with the one-to-one locking nut of connecting bolt,
The connecting bolt is locked after sequentially passing through arc-chutes end and flange by locking nut；
One buffer cell, the buffer cell includes corresponding the buffer spring for being sleeved on connecting bolt outer end, and slow
The two ends for rushing spring are against the end of arc-chutes end and flange respectively；
One blocker unit, the blocker unit is sleeved on obstruct cover of the flange away from arc-chutes side, the obstruct including one
Cover is bolted on flange, and covers all of locking nut.
Further, the outside on the connecting bolt positioned at locking nut is also threaded with a fastening screw nut.
Further, the buffer spring is any one in disk spring or helical spring.
The utility model has the advantage of：In the utility model, by being rigidly connected between traditional arc-chutes and flange
Now be replaced by the mating connection mode of buffer spring and connecting bolt, by the effect of buffer spring cause arc-chutes and flange it
Between can relatively move and reset, effectively solve the problems, such as spring, it is to avoid damaged caused by because being rigidly connected, fracture it is existing
As while the effect for passing through connecting bolt, it is ensured that relative position of the arc-chutes with flange when mobile, play certain guiding and make
With；In addition, the setting by intercepting cover, can play the sealing function of insulating gas.
By setting up a fastening screw nut on the outside of locking nut, it is ensured that the connection between connecting bolt and locking nut
Stability, it is to avoid cause the loosening between connecting bolt and locking nut because of the relative motion between arc-chutes and flange,
Ensure that the normal of product is used.
Can be chosen any one kind of them from disk spring or helical spring for buffer spring and selected, with variation.
