配线、联动：检查机构内部二次回路配接线正确；断路器内六氟化硫气体达到额

Wiring and linkage: <br>Check that the internal secondary circuit wiring of the mechanism is correct; the sulfur hexafluoride gas in the circuit breaker reaches the rated pressure; the opening and closing positions of the position indicator are consistent with the actual opening and closing status of the circuit breaker. <br>Connect the cable and send power, and conduct the electric opening and closing test. First, perform the slow opening and closing operations, and then perform the rapid opening and closing operations. <br>Electrical test: <br>measure the resistance of the conductive circuit to determine whether the contacts are affected by moisture and oxidation; check the operating mechanism and measure the insulation resistance of the opening and closing coils to determine whether the operating mechanism of the circuit breaker is rusted and whether the secondary circuit components are affected by moisture and oxidation; insulation Resistance and AC withstand voltage test to determine the moisture content of the insulation tie rod, circuit breaker arc extinguishing chamber and overall insulation.

Wiring and linkage:<br>Check that the wiring of the secondary circuit inside the mechanism is correct; The sulfur hexafluoride gas in the circuit breaker reaches the rated pressure; The opening and closing positions of the position indicator are consistent with the actual opening and closing status of the circuit breaker.<br>Connect the cable and power on to conduct an electric opening and closing test. First, perform slow opening and closing operations, and then perform fast opening and closing operations.<br>Electrical tests:<br>Measure the resistance of the conductive circuit to determine whether the contact is damp or oxidized; Check the operating mechanism and measure the insulation resistance of the opening and closing coils to determine whether the operating mechanism of the circuit breaker is rusted, and whether the secondary circuit components are damp or oxidized; Insulation resistance and AC withstand voltage test to determine the moisture condition of the insulation rod, circuit breaker arc extinguishing chamber, and overall insulation.

Wiring and linkage:<br> Check that the secondary circuit wiring inside the organization is correct; Sulfur hexafluoride gas in the circuit breaker reaches the rated pressure; The opening and closing position of the position indicator is consistent with the actual opening and closing state of the circuit breaker.<br> Connect the cable and send power, and carry out the electric opening and closing test.
