vacuum interrupter contactor,vacuum bottle for contactor

The exhaust platform process refers to the vacuum interrupter parts through brazing and argon arc welding process to be made into the exhaust pipe, and then connected to the exhaust platform for vacuum and baking degassing, and finally cold folder The process of sealing. This process, the process is complex, long route, generally have 9 processes. So the efficiency is low and the Vauum interrupter contactor parts of the pollution links. Moreover, according to this process to produce vacuum interrupter baking temperature is low (450 ℃ or so), and thus degassing is not complete. A row of packaging technology Refers to the vacuum interrupter parts of the first brazing into several parts, and then several parts assembled into the vacuum interrupter the whole, and then in the vacuum furnace to complete the exhaust, bake to the gas and brazing sealing process. This process, the process is relatively simple, there are generally 7 processes, and thus more efficient and less polluting man. ...

Pressure measurement is an important one in the vacuum interrupter parameter test. The pressure in the arc chamber is the basis for the formation of air blowing, but too high pressure will cause excessive requirements for the strength of the arc chamber housing. Therefore, the arc valve 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 interrupter. The main contents of the design of the low-voltage circuit breaker interrupter include: the shape and size of the outlet; the shape and arrangement of the grille; the structure of the exhaust channel; the size and structure of the arc chamber; the choice of gas-generating material. In the arc chamber to place gas production materials, on the one hand the use of gas to improve the pressure of the Vacuum interrupter for load break switch to promote air blowing; the other hand, the use of gas, such as hydrogen and other components con...

The insulation performance of the vacuum gap is not only affected by the performance of the contact material, but also by the contact surface conditions such as micro-bumps, attached metal particles, oxides and organic contaminants, and surface gas content. Accurate voltage can effectively improve the Vauum interrupter contactor contact between the withstand voltage strength. The finely polished electrode is much smoother than the voltage-trained surface, but the withstand voltage is not as good as the post-electrode electrode gap. For the new production of the vacuum interrupter, the frequency of the spark under the sophistication is the most simple and most effective way to improve the vacuum interrupter . The voltage is experienced mainly by the use of gap breakdown of the discharge energy of the electrode surface layer of local melting and crystallization, so that the vacuum gap with the intensity of the breakdown with the breakdown and gradually increased. Therefore, the appro...
