What is the role of high-voltage circuit breakers? (1) control action. According to the needs of power system operation Fujian outdoor vacuum circuit breakers, some or all of the electrical equipment, as well as part or all of the line inputs or out of operation. (2) protection. When a part of the power system fails, it and the protection device, automatic device compatible Hubei outdoor vacuum circuit breakers, the failure part of the rapid removal from the system Hainan outdoor vacuum circuit breakers, reduce the power range, prevent the accident breaker protection systems in all types of electrical equipment from damage and ensure trouble-free part of the security operation. Welcome to inquire buy! Breaker maintenance and operation of the circuit breaker maintenance and operation inspection (a) routine inspection of voltage and current. (2) indicates the position of the circuit breaker status and mechanical, electrical, indicating the position are the same. (3) whether the damaged insulators, cracks, with or without a corona discharge phenomenon. (4) oil color oil level, gas pressure. (5) whether the oil leakage, leakage. (6) whether the hydraulic mechanism pipeline leak, pressure is low. Welcome to inquire buy!
