High Performance VSzn 12 kV Vacuum Circuit Breaker

VSzn Vacuum Circuit Breaker,SF6 Circuit Breaker

Overview of VSzn Vacuum Circuit Breaker,SF6 Circuit Breaker

VSzn vacuum circuit breaker is based on Xi’an Senyuan VS1 vacuum circuit breaker, another new type of high-performance spring-operated vacuum circuit breaker with improved design. It is designed with high vacuum, reliable insulation performance and excellent arc extinguishing ability. Of indoor switchgear components. The circuit breaker uses a new type of energy storage motor, with a withstand voltage level of 2500V/1min, and the motor life can reach 100,000 times. Its use of integrated wiring harness greatly improves the reliability of the circuit breaker's secondary circuit, and realizes the performance of the secondary circuit without errors, looseness, and high reliability. Under normal use conditions, as long as it is within the technical reference range of the circuit breaker, it can ensure safe and reliable operation in a three-phase AC 50HZ, rated voltage 12KV and lower power distribution system. VSzn vacuum circuit breakers can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be as high as 30,000 times, and the full-capacity short-circuit current breaking times can reach 50 times. At present, the series of circuit breakers of various specifications can meet Environmental requirements such as miniaturization applications, fast-breaking capacitor banks and high-altitude use. Products are widely used in power plant, petrochemical, metallurgical and urban infrastructure construction and transformation projects
