Intelligent on-line monitoring system of high-voltage switchgear

Abstract

The invention provides an intelligent on-line monitoring system and method of a high-voltage switchgear. The intelligent on-line monitoring system comprises a partial discharge on-line monitoring system, a switchgear temperature measurement system, an intelligent data exchange terminal, a comprehensive monitoring system, a cloud platform diagnostic service system and a background management system. The partial discharge on-line monitoring system is used for monitoring the partial discharge activity of the high-voltage switchgear; the switchgear temperature measurement system is used for collecting temperature parameters of the high-voltage switchgear; the intelligent data exchange terminal can obtain intelligent sensor data in real time; the comprehensive monitoring system selectively anddeeply analyzes the equipment exception causes, finds out equipment failure points, and uploads data and diagnostic results to the cloud platform expert diagnostic system; the cloud platform diagnostic service system is used for comprehensively analyzing the operation state of the equipment by utilizing data uploaded by the intelligent data exchange terminal and data uploaded by the movable comprehensive monitoring system, and evaluating the partial discharge condition of the switchgear by combining with a failure case library; and the background management system logs in according to different user rights, and can use different functions according to the rights, and the system has the main functions of being responsible for data management, statistics and analysis, and classified storageof monitoring data. Interaction between operation and maintenance personnel and equipment management can be achieved, and the practical significance for guaranteeing safe operation of the high-voltageswitchgear is achieved.

Description

[0001] The invention relates to an intelligent on-line monitoring system of a high-voltage switchgear, and its application field is the on-line monitoring and fault diagnosis of partial discharge signals of the high-voltage switchgear. Background technique [0002] With the development of the national economy, the country has higher and higher requirements for the reliability of power system operation. High-voltage switchgear is an important link to ensure the normal operation of the power grid, and it is a very important electrical equipment in the power system. According to the relevant data of China Electric Power Research Institute, most of the insulation faults in the State Power Corporation are caused by partial discharge. Therefore, through the development of an on-line monitoring system for partial discharge of high-voltage power equipment, through real-time on-line monitoring, hidden troubles can be found in time, and measures should be taken to repair and deal with t...
