Embodiment

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

[0026] A. Connect the intelligent vacuum circuit breaker speed monitoring device to the vacuum circuit breaker, and set the sensor of the speed online monitoring device in the vacuum circuit breaker insulator;

[0027] 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;

[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 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 online monitoring of the vacuum circuit breaker speed: a pressure sensor is in...

Abstract

The invention relates to the monitoring technical field of vacuum circuit breakers, in particular to a speed online monitoring method of an intelligent vacuum circuit breaker. The method comprises the following steps that: A. an intelligent vacuum circuit breaker speed online monitoring device is connected with a vacuum circuit breaker, and a sensor of the speed online monitoring device is arranged in an insulator of the vacuum circuit breaker; B. the senor in real time collects the running parameter information of the vacuum circuit breaker, amplifies and transforms the information, and transmits the running parameter information to a control module; C. the control module analyzes and compares the running parameter information of the vacuum circuit breaker; D. the information after being processed is directly fed back to the speed online monitoring device in an acousto-optic way. According to the invention, the ON and OFF speed of the circuit breaker is instantly monitored so as to instantly master the working state of the circuit breaker and reduce premature or unnecessary outage tests and overhauls, so that the working amount for maintenance and the repairing expenses are reduced, and the reliability and economical efficiency of the electric power system are obviously improved.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breaker monitoring, in particular to an online speed monitoring method of an intelligent vacuum circuit breaker. 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 is related to the safety of power system operation. Therefore, keeping vacuum circuit breakers on and off The gate speed parameter is critical. [0003] Since the vacuum circuit breaker is in the opening process (that is, the main contact has just opened to the 3mm position) and the closing process (that is, the 3mm position before closing), it is most likely that the speed does not meet the requirements, resulting in...
