Problems solved by technology

[0003] Traditional online monitoring devices for high-voltage circuit breakers mainly monitor parameters such as the number of mechanical operations of the circuit breaker and the cumulative operating time of the switch. Most monitoring devices have a single function and only monitor the same parameters of one or more devices. It is a good combination of fault diagnosis technology and online monitoring technology, and the analysis and diagnosis are limited to exceeding the standard alarm, and the specific and detailed analysis and diagnosis are basically completed by the experimenter, the accuracy is not high, and the efficiency is low

Abstract

The invention provides an on-line monitoring device for a high-voltage circuit breaker. The on-line monitoring device comprises a sensor module and an on-line high-voltage circuit breaker monitoring unit, wherein the on-line high-voltage circuit breaker monitoring unit comprises a single-chip microcomputer module, a communication module, a human-machine interaction module and an alarming module; the single-chip microcomputer module is a functional module and is integrated with a data amplification module, a filtering module, an A / D (analog / digital) conversion module, a micro processor module, a fault diagnosis module and an interface module. The on-line monitoring device for the high-voltage circuit breaker performs real-time monitoring according to switch on and switch off current of the circuit breaker and state information such as a travel mechanical characteristic of a main contact, so that the definite state information can be supplied in real time, and local digitalization, remote networking and monitoring and prewarning automation are realized; therefore the reliability of running of the circuit breaker is improved. The device can comprehensively, scientifically and accurately monitor a real-time running state of the high-voltage circuit breaker on line, effectively avoid strong electromagnetic interference and completely and safely send data to a monitoring terminal.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of circuit breakers in the electric power industry, and in particular relates to an on-line monitoring device for high-voltage circuit breakers. Background technique [0002] In recent years, some domestic units and manufacturers are also carrying out the work of circuit breaker mechanical characteristic monitoring and fault diagnosis. In 1992, Jilin Electric Power Bureau set up a project "Monitoring of Mechanical Characteristics of Circuit Breakers"; in 1994, the Switch Research Institute of China Electric Power Research Institute successfully developed the KZC-1 high-voltage circuit breaker on-line monitor; 1 High-voltage circuit breaker mechanical parameter measurement and analysis system, which can monitor closing / opening coil current, stroke-time characteristic curve and vibration signal. The research work at this time is mainly carried out around the condition maintenance of circu...
