Gas effect, high temperature and high pressure gas a part that electric arc generates flows into auxiliary piston through air guide channel inside arcing contact and arc extinguishing sprays
The auxiliary tank that mouth is formed, when auxiliary piston leaves quenching nozzle, the gas in auxiliary tank is discharged, and plays the effect of arc extinguishing
Fruit.
It is that the present invention obtains the utility model has the advantages that
1, the structure that the present invention is combined using auxiliary piston and matched quenching nozzle, by arcing contact
Air guide channel is arranged in portion, and the high temperature and high pressure gas that can generate electric arc, part introduces in auxiliary tank, can make full use of
The high-temperature gas that electric arc heated effect generates is as arc extinguishing air pressure.In the motion process backwards of auxiliary piston and quenching nozzle,
Certain inspiratory effects are generated, high temperature and high pressure gas a part that electric arc generates flows into auxiliary through air guide channel inside arcing contact
The auxiliary tank that piston and quenching nozzle are formed, accelerates arc gap radiation processes, is conducive to successfully blow-out.
2, in the case where cut-offfing short circuit current, hyperbar hot gas is through expanding chamber, arcing contact end and catchment
" auxiliary tank ", the area pressure persistently increase, and are conducive to generate strong arc blow-out effect, are equivalent to and improve expanding chamber appearance
Product, and then can reduce the size of Switch main body, aeration quantity can also be reduced in a way, simplified the structure of breaker,
Reduce cost.
3, in the several milliseconds of times of contact separation, increased by the closed area pressure that auxiliary piston and quenching nozzle are formed,
When auxiliary piston leaves quenching nozzle, stronger air-blowing effect can be generated, arc extinguishing is played the role of.
4, linking arm hollow area is located at side setting gas shutoff plug of the port far from arcing contact touching pole, and gas shutoff plug can basis
Need to adjust the position in linking arm, to play the role of adjusting air pressure.
