Fault inspection and solution of circuit breaker

First of all, check whether the panel of the operating mechanism sinks. If it sinks, it will have a great impact on the driving machine, and the associated contact travel will also be blocked. The possibility of successful closing will be reduced, so there will be problems. So what are the solutions? In fact, you only need to adjust and loosen the screws on the panel, fix it, lift the panel up slightly, and fix the screws again, so there won't be much problem. The correctness of the position of    stop is also closely related to the normal operation of the circuit breaker. When we find that the position of the stop on the guide rail is not correct, we can adjust it to avoid more serious things. Use the stopper to counter the outside of the axle shaft, so as not to let the axle shaft and the skip buckle buckle, so as to avoid many faults. The pressure loss release is also prone to failure. If it is not in the correct position, its metal sheet will make the release mechanism act under the action of spring force. We should check the filter capacitor, and then check whether the coil of the voltage loss release has an open circuit, and check whether the metal on it has been deformed. Pay attention to that the distance between the metal sheet and the top bar is about 0.5-1 mm.
