12kV Vacuum Circuit Breaker | ZW32 Medium Voltage Breaker

This 12kV vacuum circuit breaker uses the most advanced circular ceramic capacitor for power collection and sampling, which can maintain stable performance in a variety of harsh environments.

This vacuum circuit breaker adopts innovative design, has independent intellectual property rights, and has obtained a number of national technical patents.

This ZW32 12kV vacuum circuit breaker has 12 power taking and sampling capacitors (expandable up to 15 capacitors), 6 current sampling. The phase voltage and zero sequence voltage of the power supply side and the load side can be sampled and taken, and the phase current and zero sequence current of the load side can be sampled.

Using a new bistable, double coil repulsion + magnetic drive operating mechanism, this medium voltage vacuum circuit breaker has novel and simple structure, small size, fast execution rate, stable action, can achieve synchronous breaking function, reduce the splitting and closing pull arc and current impact, with high reliability.

Built-in FTU of the 12kV vacuum circuit breaker adopts the whole life design scheme, increasing waterproof, shock-proof and anti-electromagnetic interference design, no output cable, realizing primary and secondary integration with high reliability and more convenient installation.

The vacuum circuit breaker comes with APP handheld operating tablet, automatic connection and password input control.

To solve the problem of data transmission in plateau and remote areas, this ZW32 12kV vacuum circuit breaker has medium voltage online carrier technology, which can realize seamless control and monitoring of the whole region and the whole climate.

FTU, combined with advanced fast fault judgment algorithm, enables the medium voltage vacuum circuit breaker to reliably remove faults from the power supply side in the shortest time, reduce voltage dips, prevent fault crossing and ensure the normal operation of the power grid.

With built-in temperature compensation constant temperature system, when the ambient temperature is below 0 degrees, the 12kV vacuum circuit breaker automatically heats the battery to ensure the life and temperature quality of the battery.

The fault detection response time of the vacuum circuit breaker controller is 2.64ms.
Circuit breaker fault removal time is 11.68ms.
