Dynamic stick 63 continues to swing, to drive pointer 64 to continue to swing, until pointer 64 is rocked to alert zone 625；So that staff
Gone out by instruction 62 observable of disk and switchs whether the case where poor contact occur after closure, without opening distribution box,
The high temperature scald for being switched on and off poor contact generation is avoided, reduces the probability of peril generation, and improve staff's
Working efficiency；If being in contact bad situation after closing the switch, a large amount of heat can be generated, so that the ethyl alcohol in piston rod 42
Liquid 422 is heated to be volatilized into alcohol gas, and alcohol gas is transmitted in fan-shaped cavity 621 by tracheae 423, logical in alcohol gas
During crossing the transmission of tracheae 423, so that tracheae 423 occurs to shake up and down, to generate bell after driving jingle bell 424 to shake
Sound has saved work so that staff can judge whether switch the case where poor contact occurs after closure by the tinkle of bells
It the working time for making personnel's detection switch closed state, improves work efficiency；Pass through the mistake that tracheae 423 transmits in alcohol gas
Cheng Zhong, so that tracheae 423 occurs to shake up and down, so that the tinkle of bells is generated after driving jingle bell 424 to shake, so that staff can
Judge whether switch the case where poor contact occurs after closure by the tinkle of bells, has saved staff's detection switch closure
It the working time of state, improves work efficiency；During switch will be closed, switch contact 5 and No. two insulators 4 it
Between can generate high-voltage arc, risk is larger, thus No. two 4 tops of insulator setting arc-extinguish chamber 7 can effectively avoid out
It closes and generates arc phenomenon between contact 5 and No. two insulators 4；Reduce the probability of peril generation；Wherein, arc-extinguish chamber 7 is most
Excellent model HD13-400A type；Since Part Coal Mine slag can remain in No. two 4 tops of insulator, easily there may be safe things
Therefore therefore be provided with stomata 44 on No. two 4 tops of insulator, during switch opening and closing, gas in cylindrical cavity 41
It can be sprayed by stomata 44, cleaning action is carried out to No. two 4 top end surfaces of insulator, coal mine slag is avoided to push up in No. two insulators 4
The remnants of end surfaces；It can be fallen into due to Part Coal Mine slag in the interlayer of arc-extinguish chamber 7, so that the arc quenching effect of arc-extinguish chamber 7 is influenced,
Therefore, it is equipped with hairbrush 71 between the interlayer of arc-extinguish chamber 7, when gas is sprayed out of cylindrical cavity 41, blows the rotation of hairbrush 71,
It realizes to the cleaning effect in 7 interlayer of arc-extinguish chamber, arc-extinguish chamber 7 is avoided to fail, to generate electric arc near switch, cause to endanger
Danger.
