Full-state sensing system of high-voltage ring main unit

Abstract

The invention provides a full-state sensing system of a high-voltage ring main unit, which belongs to the technical field of ring main unit monitoring. The system comprises a ring main unit, a monitoring sensor arranged in the ring main unit, and DTU communication equipment connected with the monitoring sensor, wherein the monitoring sensor comprises a partial discharge sensor, a temperature and humidity sensor, a gas density relay, a mechanical characteristic sensor and an intelligent measurement and control terminal. The DTU communication equipment is in communication connection with the cloud system platform through the intelligent gateway. The cloud system platform can transmit the DTU communication equipment to the data for storage and send the data to the monitoring terminal. Real-time monitoring of charge parameters, internal temperature and humidity, partial discharge, busbar temperature, gas pressure and mechanical characteristic parameters of the high-voltage cabinet can be realized; a standby fault alarm function can be realized, equipment data real-time browsing, historical data query and export, equipment health state evaluation and alarm information multi-terminal pushing are supported, and the use state of the ring main unit can be known in real time through the monitoring terminal.

Description

technical field [0001] The invention belongs to the technical field of ring network cabinet monitoring, and in particular relates to a high-voltage ring network cabinet full-state sensing system. Background technique [0002] With the continuous development of the economy and the increasing impact of electric energy on people's lives, especially for urban areas with high load density, the reliability of power supply is particularly important. By establishing a power distribution network based on the ring network structure, it can effectively improve the reliability of power supply, ensure the continuity of power supply, and minimize the impact of power distribution equipment failures and maintenance power outages. As an important device in the ring network operation mode ——Ring network cabinets are also more and more widely used in distribution network transformation. Due to the different types of load switches used, ring network cabinets are divided into gas-producing ring...

AI Technical Summary

Problems solved by technology

Due to the different types of load switches used, ring network cabinets are divided into gas-producing ring network cabinets, compressed-air ring network cabinets, vacuum ring network cabinets, and SF6 ring network cabinets. Type ring network cabinets have fatal defects and low reliability due to the switches used, and are now basically eliminated

Vacuum ring network cabinets and SF6 ring network cabinets are widely used due to their high performance indicators, operation and maintenance, and reliability of maintenance and operation. Lack of sense of operation etc.
