In practical applications, the circuit breaker electromagnetic operating mechanism can achieve frequent operation within its operating current range, or multiple short-circuit currents. Long mechanical life, the electromagnetic operating mechanism of the circuit breaker is suitable for reclosing operation and has high operational reliability and service life. The structure uses a solid insulation structure—integrated solid-sealed poles for maintenance-free operation.
When installing and using, the electromagnetic operation mechanism of the circuit breaker can be selected in different manners in the switch cabinet, for example, it can be fixed or withdrawable, and can also be installed on the frame. The user can select different types of circuit breaker electromagnetic operating mechanisms according to the protected object, and the anti-fouling type and high prototype can be selected for different use places.
Under normal circumstances, the operating conditions of the electromagnetic operating mechanism of the circuit breaker mainly include: 1, can be used indoors and outdoors; 2, the ambient temperature is -40 ° C ~ +40 ° C; 3, the altitude does not exceed 3000 m (porcelain sleeve does not exceed 1000m); 4, the power frequency is not less than 48Hz, not more than 62Hz; 5, the long-term application of the power frequency voltage between the terminals of the electromagnetic operating mechanism of the circuit breaker does not exceed the continuous operating voltage of the electromagnetic operating mechanism of the circuit breaker.
