When the number of circuit breaker trips approaches the maintenance cycle, the reclosing device must be disengaged.

The circuit breaker position indicator should correspond with the signal of the indicator light and the meter indication.

Generally, manual mechanical circuit breakers are not permitted.

Before closing the circuit breaker, the relay protection should be checked in accordance with regulations. Before opening the circuit, consider the arrangement of the load.

After the circuit breaker is closed, confirm that all three phases are connected and the automatic device is set according to regulations.

Hydraulic mechanisms are prohibited from operating the spring energy storage mechanism when an abnormal pressure signal is emitted.闸操作 is prohibited when an energy storage signal is issued.

During operation, the control switch should not return too quickly; it should be released only after the red and green signal lights are activated, to prevent the short-term energization of the switching coils, which could cause them to fail to operate. The electromagnetic mechanism should not return too slowly to avoid auxiliary switch failure and the burning of the closing coil.

Therefore, the ZW32-12 circuit breaker must meet these requirements during operation to ensure its effective function during use.
