Ring main unit multi-parameter intelligent online monitoring system

Abstract

The invention relates to a multi-parameter intelligent online monitoring system for a ring main unit, which belongs to the field of ring main unit management and comprises a gas pressure sensor, a voltage and current sensor, an opening and closing sensor, a temperature and humidity sensor, an electric motor, a storage battery, a power supply transformer and an intelligent control unit. The gas pressure sensor is used for detecting the gas pressure in the ring main unit box body; the voltage and current sensor is used for detecting battery voltage and current states of an electric operating mechanism of the ring main unit; the opening and closing sensor is used for detecting the opening and closing state of the ring main unit; the temperature and humidity sensor is used for detecting the temperature and humidity in the ring main unit box body; the intelligent control unit is used for receiving various collected data, analyzing and judging the state of the ring main unit before remote opening or closing operation, and ensuring the safety of the remote opening or closing operation; the storage battery and the power supply transformer provide a power supply for the electric motor, and the electric motor receives an instruction of the intelligent control unit to carry out remote switching-off or switching-on operation.

Description

technical field [0001] The invention belongs to the field of ring network cabinet management and relates to a multi-parameter intelligent online monitoring system of a ring network cabinet. Background technique [0002] The user load demand is increasing, and the power supply pressure of the power grid is increasing. Under the severe situation of serious requirements imposed by economic development, the distribution network, as an important link in the power supply, is also showing its backwardness. Infrastructure construction The uncoordinated situation has a certain impact on people's economic production and daily life. Under such a development environment, it has gradually expanded, resulting in social production and living electricity and power grids. For this reason, promoting the improvement and innovation of power companies and power supply companies, and promoting the development and construction of urban and rural distribution network automation have become the cur...

AI Technical Summary

Problems solved by technology

[0004] Most of the intelligent protection terminals of the ring main unit currently used have problems such as many wiring joints, heavy workload, and easy wiring errors and short circuits; in the future, with the further development of power distribution automation, the signal volume collected from primary equipment will also increase There will be more and more, so it is very necessary to reduce the wiring between various devices, achieve reasonable optimization and simplification, and further improve the reliability of signal transmission and operation between primary and secondary devices

At the same time, the traditional ring network cabinet lacks the status monitoring of the ring network cabinet, and cannot understand the running status of the ring network cabinet in real time during long-term operation.
