What are the first-line brands of 10kv high-voltage vacuum circuit breakers? Shaanxi Taikai High Voltage Switch Manufacturing Co., Ltd. ZW32-12 / M type vacuum permanent magnet circuit breaker uses a vacuum arc extinguishing chamber, uses vacuum as an arc extinguishing and insulating medium, and has a very high degree of vacuum. When the moving and static contacts are electrically opened under the action of the operating mechanism, a vacuum arc will be generated between the contacts. At the same time, due to the special structure of the contacts, an appropriate longitudinal magnetic field will also be generated in the gap of the contacts. Promote the vacuum arc to be a diffusion type, and evenly distribute the arc on the contact surface to burn, maintain a low arc voltage, and when the current naturally crosses zero, residual ions, electrons and metal vapor can be in the order of microsecond Compounded or condensed on the surface of the contact and the shield, the dielectric strength of the interruption of the arc extinguishing chamber is quickly restored, so that the arc is extinguished to achieve the purpose of breaking. Because the longitudinal magnetic field is used to control the vacuum arc, the vacuum circuit breaker has a strong and stable breaking current capability.
Energy storage: 
The energy of ZW32-12 / M vacuum permanent magnetic circuit breaker is stored in high-performance capacitors, which are installed in the intelligent controller unit box. Capacitor instantaneously
When the discharge provides energy. The charging energy of the capacitor is provided by the main power supply or backup power supply of the control unit, the charging time is not more than 10s, and the capacitor voltage error is ≤1V.
