Intelligent ring main unit state monitoring system

Abstract

The invention provides an intelligent ring main unit state monitoring system. The system comprises an upper computer, a monitoring host and at least one ring main unit, wherein the upper computer and the monitoring host are connected through a communication network and realize information transmission; the monitoring host transmits information to the upper computer in real time, the upper computer stores the received information, and the monitoring host is connected with the ring main units. The system is characterized in that each ring main unit comprises a cabinet body, an ultrasonic monitoring assembly, a temperature and humidity monitoring assembly and a water monitoring assembly are arranged in the cabinet body and connected with the monitoring host through an interface module and transmit information about the ring main units to the monitoring host. The intelligent ring main unit state monitoring system has a simple structure and can monitor the work state of the ring main units in real time.

Description

technical field [0001] The invention belongs to the technical field of ring network cabinet monitoring, and in particular relates to an intelligent ring network cabinet state monitoring system. Background technique [0002] Ring network cabinet status monitoring is an important technical means for the working status of the ring network cabinet. The partial discharge of the ring network cabinet, the temperature and humidity inside the cabinet, and the water level of the cable trench will all affect the status of the ring network cabinet. At this stage, the main factors that cause the failure of the ring main unit are: external damage, condensation caused by high internal humidity, corrosion of cable heads, corrosion of chemicals, etc. When partial discharge occurs inside the ring main unit, the ultrasonic wave inside the ring main unit will exceed the standard. Therefore, monitoring the ultrasonic intensity in the ring main unit can determine whether there is partial discharg...

AI Technical Summary

Problems solved by technology

To grasp the state of the ring network cabinet, it is possible to rely on manual on-site inspection, on-site partial inspection twice a year, accurate infrared temperature measurement, etc., which cost a lot of manpower and financial resources

During the inspection period, it is only possible to judge whether the ring network cabinet is in good condition after measuring with special instruments and meters. It cannot monitor the working reliability of the ring network cabinet in time and in real time, and wastes manpower, material and financial resources, and cannot monitor the working status of the ring network cabinet in real time. monitor
