The circuit breaker has overload, short circuit and under-voltage protection functions and has the capacity of protecting circuits and power supplies. The circuit breaker is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum. The arc extinguishing device has the advantages of small volume, light weight, suitability for frequent operation and no need of maintenance for arc extinguishing, and is more popular in power distribution networks. In an operating mechanism of the circuit breaker, the opening and closing coil is not direct power of the action of the circuit breaker and is only used for energy release of an energy storage component, the opening and closing coil comprises a coil and a push rod, and the working process of the opening and closing coil is that after the coil is electrified, the push rod positioned in the coil has speed under certain current and can move horizontally. The push rod which translates at a certain speed has impact force which is a power source for pushing the operating mechanism. In the current circuit breaker overhaul regulations, the overhaul and maintenance work of the opening and closing coil comprises the following two points: firstly, the resistance value of the coil on the coil is measured, and the resistance value is required to be in accordance with the standard value range. And related personnel manually operate the opening and closing coil to ensure that a push rod in the coil is not jammed. In practice, the problem that the mechanical force of the push rod is insufficient can still occur in the normally overhauled opening and closing coil. Analysis shows that the maintenance of the opening and closing coils belongs to qualitative maintenance. However, the opening and closing coils are used for a long time, or the mechanical force gradually decreases after a small part of the coils are aged, and a worker cannot estimate the expected service time of one opening and closing coil only through the qualitative maintenance, so that the problem that the opening and closing coils suddenly fail in use due to the qualitative maintenance cannot be avoided. At present, no special detection tool is available for quickly and accurately measuring the mechanical force of the opening and closing coil in a quantitative manner. In addition, the maintenance of the opening and closing coils cannot be carried out on the site at present, and the maintenance efficiency is seriously influenced due to the obstacles caused by the troubleshooting of the circuit breaker and the whole site.
