System for monitoring environment of cable trenches of transformer station

Abstract

The invention discloses a system for monitoring environment of cable trenches of a transformer station. The system mainly comprises a monitoring management server, a local server, a 4G router, a plurality of gateways, and smart covers. The monitoring management server is connected to the 4G router via a 4G network. The local server is connected wiredly to the 4G router. Each smart cover is connected to a gateway via a ZigBee network. Each gateway is connected to the 4G router via the wireless network. The smart covers collect all environmental information of the cable trenches and upload it tothe local server and the monitoring management server through the 4G router. The system for monitoring environment of cable trenches of the transformer station realizes real-time collection and display of environmental data in the cable trenches by using the smart covers and constructs the monitoring management server, the local server, and the smart covers into a complete cable trenches environment monitoring platform by using the wireless ZigBee technology, a WiFi technology, and a sensor technology, so that can monitor the operating environment of the cable trenches in real-time.

Description

technical field [0001] The invention relates to the technical field of substation maintenance, in particular to a substation cable trench environment monitoring system. Background technique [0002] The cable trench is an indispensable infrastructure of the substation. The cable in the trench not only involves power transmission, but also involves equipment such as relay protection, automatic control, communication, measurement and metering. It is the nerve center of the substation. Once a cable fails, not only inspection and processing It is difficult and takes a long time, and it may also cause the relay protection or control circuit to fail, causing the accident to expand or even damage the main equipment, and the production cannot be resumed for a long time. [0003] Different from ordinary overhead cable transmission systems, cable trenches or tunnels are built underground, so the operating conditions of the cables are determined by the characteristics of the cables the...

AI Technical Summary

Problems solved by technology

At present, smart substations pay more attention to water immersion monitoring and fire monitoring. Water immersion sensors and smoke sensors can monitor the environment in cable trenches to a certain extent, but they still do not meet the inspection requirements.

For example, in the 500kV Guanshan substation, a section of ice-melting insulating tube mother passes through the underground cable trench. When the temperature of the cable section needs to be measured during the ice-melting period, the cable trench cover needs to be lifted to measure the temperature. The safety risk is high, the efficiency is low, and it is impossible. do full coverage

And most of the sensors are arranged in the cable trench wells, the location is limited, the sensors need to be connected with the nearby monitoring host to realize the data collection in the cable trench, the operation is cumbersome, and the maintenance is inconvenient
