ZW32M-12 series outdoor high-voltage permanent magnet vacuum circuit breaker

◇ Product Overview:

ZW32M-12 series outdoor high-voltage permanent magnet vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. Mainly used for breaking and closing load current, overload current, and short-circuit current in systems. Suitable for protection and control in substations and distribution systems of industrial and mining enterprises, as well as places with frequent operation of rural power grids.

Main functional features:

1. Intelligent control function: In addition to local switch status control, three-stage overcurrent protection, and triple automatic reclosing, this circuit breaker also has an RS-485 communication interface that can achieve telemetry, remote adjustment, remote control, remote communication, and other functions, suitable for various scales of automated distribution systems.

2. Permanent magnet operating mechanism: This circuit breaker adopts the currently excellent permanent magnet kneading mechanism, and the mechanism components are not worn. Its mechanical life can reach 30000 times, which is three times that of ordinary spring mechanisms. Due to the 70% reduction in the number of mechanical parts of permanent magnet mechanisms compared to spring mechanisms, the reliability of switches has been significantly improved.

3. Fully sealed structural design: The vacuum arc extinguishing chamber, operating mechanism, and connecting rod of this circuit breaker are fully sealed inside the circuit breaker base, solving the problem of corrosion of circuit breaker parts caused by condensation. The product can achieve maintenance free operation for 10 years.

4. Miniaturization structure: The circuit breaker adopts a new composite solid insulation material, which organically combines the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into an integrated solid sealed pole, completely solving the contradiction between miniaturization of the vacuum arc extinguishing chamber and meeting external insulation requirements. The entire product design is reasonable, the structure is compact, there is no condensation inside, and the mechanism is rust free.
