Abstract

The invention discloses a switch equipment defect intelligent detection and analysis system including an intelligent detection terminal, an IoT communication system and a background monitoring system. The intelligent detection terminal includes a sensor unit and a data processing unit. The IoT communication system adopts a ZigBee wireless network for communication. Different signals detected by the sensor unit are processed by the data processing unit and are then transmitted to the background monitoring system through the ZigBee wireless network. According to the invention, engagement and disengagement current parameters, mechanical property parameters and contact temperature data of the switch equipment are collected in real time and evaluation and failure diagnosis of the integral state of the switch equipment are performed through the intelligent detection terminal and the background monitoring system.

Description

technical field [0001] The invention relates to an intelligent detection and analysis system for switchgear defects. Background technique [0002] Compared with transformers and generators, the on-line monitoring technology of high-voltage switchgear started relatively late. In a sense, the concepts of "GIS technology" and "condition-based maintenance" have promoted the development of on-line monitoring technology for switchgear. But it was not until the 1990s that the on-line monitoring technology of switchgear, especially high-voltage circuit breakers, gradually developed. This is mainly because the current power system accidents no longer measure the economic losses caused by them simply by their harm to the power system. [0003] With the rapid development of semiconductor technology and various new monitoring technologies, conditions have been created for on-line monitoring of switchgear. Some advanced countries have entered the era of predictive maintenance based on ...
