ZW32-12M permanent magnet high voltage vacuum circuit breaker

Product Description of Permanent Magnet High Voltage Vacuum Circuit Breaker
Permanent Magnet High Voltage Vacuum Circuit Breaker combines the world's latest permanent magnet mechanism and epoxy resin integral casting solid insulation technology and other advanced technologies
and adopts vacuum opening Breaking technology has the characteristics of long electrical life, reliable breaking and long-term complete maintenance-free. The external insulation is integrally cast with imported outdoor-specific epoxy resin, which has the advantages of UV resistance, flashover resistance, and pollution resistance. This product is completely oil-free, non-toxic, maintenance-free and does not pollute the environment.
The permanent magnet vacuum circuit breaker adopts an advanced permanent magnet mechanism with stable and reliable mechanical performance and is equipped with a manual opening mechanism. When necessary, it can be manually opened and closed on site
This product has many advantages such as small size, light weight, convenient operation, reliable operation, pollution-free and maintenance-free.

Second product structure and working principle
/The vacuum permanent magnet circuit breaker is mainly composed of It is composed of an integrated solid-sealed pole current transformer permanent magnet operating mechanism and a box body. This model of circuit breaker has a miniaturized design and its outer casing is made of high-quality stainless steel. It is also equipped with a manual emergency opening device. Isolating switches and current transformers can be selected according to user needs. The control of the
/ type permanent magnet vacuum circuit breaker is completed by the matching intelligent control unit. The switch opening and closing operation can be realized locally or remotely controlled through the communication interface. Other information of the circuit breaker can also be transmitted to the control center, and the communication channel can choose cable fiber/etc.
The intelligent control unit is installed close to the circuit breaker and connected to the circuit breaker through a control cable. The power supply of the intelligent control unit is divided into main and backup power supplies. The main power supply is or is obtained from a high-voltage line and the backup power supply is provided by a battery and installed in the intelligent control unit box. When the main power supply is working normally, the backup power supply is charged. When the main power supply is lost, the backup power supply can still control the circuit breaker and other operations in the control unit. When the backup power supply is fully loaded, it can be maintained. The whole machine should work no less than 1 hour.
The operating mechanism of the circuit breaker is equipped with a manual emergency opening handle, which is used for emergency opening operation when the control system or power supply fails.
