Embodiment

[0025] Such as image 3 Shown: an intelligent vacuum circuit breaker opening and closing speed monitoring method, the method includes the following steps:

[0026] A. Connect the opening and closing speed monitoring device of the intelligent vacuum circuit breaker to the vacuum circuit breaker, and set the sensor of the opening and closing speed monitoring device on the lever arm of the vacuum circuit breaker;

[0027] B. The sensor collects the operating parameter information of the vacuum circuit breaker in real time, then processes the signal, and transmits it to the control module;

[0028] C. The control module analyzes and compares the operating parameter information of the vacuum circuit breaker;

[0029] D. The processed information is directly fed back to the opening and closing speed monitoring device through sound and light.

[0030] The control module analyzes and compares the operating parameter information of the vacuum circuit breaker, that is, the opening and...

Abstract

The invention relates to the technical field of monitoring a vacuum circuit breaker, and particularly relates to an opening and closing speed monitoring method of an intelligent vacuum circuit breaker. The opening and closing speed monitoring method comprises the following steps of: A, connecting an opening and closing speed monitoring device of the intelligent vacuum circuit breaker with the vacuum circuit breaker, and arranging a sensor of the opening and closing speed monitoring device on a crank of a lever of the vacuum circuit breaker; B, collecting operation parameter information of the vacuum circuit breaker through the sensor, carrying out conversion treatment on signals, and transmitting opening and closing speeds to a control module through a 485 interface; C, analyzing and comparing the operation parameter information of the vacuum circuit breaker through the control module; and D, directly feeding back the processed information to the opening and closing speed monitoring device in an acousto-optic manner. The opening and closing speed monitoring method of the intelligent vacuum circuit breaker provided by the invention monitors the opening and closing speeds of the circuit breaker in real time, and a working state of the circuit breaker can be learned in time, so that the maintenance working amount is reduced, the maintenance cost is reduced, and the reliability and the economical efficiency of an electrical power system can be 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 opening and closing speed monitoring method. Background technique [0002] 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. The opening and closing speed parameter of the vacuum circuit breaker is very important for the circuit breaker. Compared with measuring the opening and closing speed of the circuit breaker with the pressure sensor, the opening and closing speed measured by the acceleration sensor used in this example is more accurate. [0003] Since the vacuum circuit...
