Embodiment

[0027] like image 3 Shown: a method for monitoring the performance of the closing spring of an intelligent vacuum circuit breaker, the method includes the following steps:

[0028] A. Connect the intelligent vacuum circuit breaker closing performance monitoring device to the vacuum circuit breaker, and install the sensor of the closing spring performance monitoring device inside the closing spring;

[0029] B. The sensor collects the operating parameter information of the vacuum circuit breaker in real time, then amplifies and converts the signal, and transmits it to the control module;

[0030] C. The control module analyzes and compares the operating parameter information of the vacuum circuit breaker;

[0031] D. The processed information is directly fed back to the closing spring performance monitoring device through sound and light.

[0032] The control module analyzes and compares the operating parameter information of the vacuum circuit breaker, that is, the performa...

Abstract

The invention relates to the field of monitoring technologies for vacuum circuit breakers, in particular to intelligent device and method for monitoring switch-on spring performance of a vacuum circuit breaker. The device comprises a circuit breaker, a sensor, a controller and output equipment, wherein the sensor is used for monitoring operational parameters of the circuit breaker and sending an acquired real-time modeling signal to the controller; the controller is used for receiving the operational parameters output by the sensor and processing the acquired parameters to calculate out a corresponding switch-on spring force value which is transmitted out through the output equipment; the sensor is a pressure sensor; and the operational parameters of the sensor are force value parameters of the sensor. According to the invention, whether the switch-on spring of the vacuum circuit breaker is fatigued or not can be timely and accurately judged, so that the working state of the circuit breaker can be timely known, untimely or unnecessary power failure test and maintenance can be reduced, maintenance workload is also reduced, maintenance cost is saved, and the reliability and economical efficiency of an electric power system are both obviously improved.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breaker monitoring, in particular to an intelligent vacuum circuit breaker closing spring performance monitoring device and method. Background technique [0002] Power equipment is the most important core part of smart grid, and its normal operation is the fundamental guarantee of grid security. Today's society is more and more dependent on electric energy, and it also puts forward higher requirements for the safety and reliability of power supply equipment. Vacuum circuit breakers are used as protection and control appliances in power systems, switching loads of various natures and power circuits in normal and abnormal states, which is related to the safety of power system operation. Therefore, checking the fatigue of the closing spring is crucial. To a certain extent, it affects the closing speed, so it is very important to monitor the fatigue of the closing spring.
