(1) the arc chamber pressure is an important basis for the formation of air blowing, but too high pressure will cause the arc chamber shell strength is too high.
(2) the pressure of the arc chamber is an important basis for the formation of air blowing, but too high pressure will cause excessive pressure on the arc chamber shell requirements.
(3) vacuum interrupter optimization design of an important goal is to improve the breaking performance at the same time, as much as possible to reduce the pressure inside the arc chamber.
(4) the use of gas-generating materials to improve the pressure of the arc chamber to promote air blowing, while the use of gas generated by cooling the Vacuum interrupter for vacuum circuit breaker , can significantly improve the disconnection of the arc chamber performance. Choosing the right gas-producing material is important for optimizing the design of the interrupter.
(P) (POM), nylon, PBT (polycarbonate) three kinds of gas production materials, experiments show that nylon is more suitable for gas production materials.
