Real-time monitoring system of low-voltage power distribution cabinet

Abstract

The invention discloses a real-time monitoring system of a low-voltage power distribution cabinet. The real-time monitoring system comprises a data acquisition module, a data analysis module, a control module, an execution module, a communication module, a warning module and a background, wherein the data acquisition module comprises a temperature monitoring unit, a voltage transformer, a currenttransformer and a humidity monitoring unit, the temperature monitoring unit is used for monitoring temperature change in a cabinet body and temperature change of a cable and a surface of an instrumentin real time and timely reflecting the detected data to the data analysis module, the voltage transformer is used for monitoring voltage change in the circuit, the current transformer is used for monitoring current change in the circuit, and the humidity monitoring unit is used for monitoring a humidity index in the cabinet body in real time and timely reflecting the humidity index to the data analysis module. By the real-time monitoring system, the change of each numerical value in the power distribution cabinet can be monitored in real time, the safe working of the power distribution cabinet is ensured, the trouble of periodic manual check is omitted, and a safety accident is reduced.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring systems, in particular to a real-time monitoring system of a low-voltage power distribution cabinet. Background technique [0002] In the power system, the safety and reliability of power equipment is an important part of ultra-large-scale power transmission and distribution and grid security. Among them, the power switch distribution cabinet is an important equipment widely used in the power transmission and distribution system, and its safety and reliability are subject to more and more There are more and more concerns that during the long-term operation of the equipment, the joint parts of the switchgear, the conductive part of the disconnector and other parts will generate heat due to excessive contact resistance due to poor manufacturing, transportation, installation and aging. If the temperature of these heating parts cannot Accurate detection without timely maintenance will lea...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a real-time monitoring system for a low-voltage power distribution cabinet, which can detect the temperature, humidity, water level in the cabinet and the voltage and current changes in the circuit in real time, and can display the collected data in time and take measures through analysis. Self-adjustment within a certain range, with the advantages of an alarm module, which solves the problem that it cannot detect the changes of various data in the cabinet in time, and can only rely on manual regular inspections, which is prone to safety accidents.
