Distributed multi-stage intelligent fault diagnosis system for power equipment

Abstract

The invention discloses a distributed multi-stage intelligent fault diagnosis system for power equipment, and the system comprises a pedestal, and a fault diagnosis instrument housing is fixedly disposed above the pedestal. The electrical input end of the PLC control module is connected with a fault knowledge base module. The information extraction module is connected to the electrical input end of the fault knowledge base module, and the electrical input end of the information extraction module is connected with a fault detection module; and the comparative analysis module is connected to the electrical output end of the PLC control module, and the electrical output end of the comparative analysis module is connected with a fault diagnosis module. Compared with an existing device, the distributed multi-stage intelligent fault diagnosis system for the power equipment can detect the power equipment through the fault detection module, extract similar fault information from the fault knowledge base module storing various fault conditions through the information extraction module, and quickly find out fault causes.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a distributed multi-level intelligent fault diagnosis system for power equipment. Background technique [0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. What electrical equipment includes mainly refers to transformers, reactors, capacitors, combined electrical appliances, circuit breakers, transformers, lightning arresters, coupling capacitors, transmission lines, power cables, grounding devices, Generators, condensers, motors, closed busbars, thyristors, etc., occasionally fail during the use of power equipment, so a distributed multi-level intelligent fault diagnosis system for power equipment is used. [0003] When the existing power equipment fails, it usually requires electric workers to diagnose and repair the fault based on experience. When the fault is difficult, it will take a lot of time, and at the s...
