Problems solved by technology

Especially in the season of high temperature and heavy load, a large number of inspections are carried out to measure the infrared temperature of the cable joints in the well ditch, the inspection of the safety of the manhole cover to prevent theft and damage, and the observation and detection of water accumulation in the well ditch, fire prevention, etc., but cannot be grasped in real time. However, in actual work, there are still many cables running with diseases, causing explosions, fires and other accidents, causing huge losses and impacts on the power sector and society

Abstract

The invention relates to an intelligent online monitoring and pre-warning system for cable operation condition. The intelligent online monitoring and pre-warning system comprises a monitoring terminal and a monitoring center master station, wherein the monitoring terminal acquires monitoring parameters of the cable operation condition, such as the grounding current of the metal protective layer of the cable, cable joint temperature, combustible gas content, poisonous gas content, oxygen gas content, smoke, water level and manhole cover security, in real time and reports the acquisition data to the monitoring center master station in a timing manner through a wireless network; the monitoring center master station is used for timely carrying out storage, statistic, analysis, display and processing on the reported acquisition data and has functions of acquiring synthetic data of cable operation, monitoring the operation state in real time, displaying image data, pre-warning a fault and giving an alarm, carrying out statistic analysis of information data and the like. The intelligent online monitoring and pre-warning system can provide an effective monitoring method for ensuring the cable trench line security, ensure that the high-voltage cable line runs stably and reliably and greatly improve the power supplying reliability.

Description

technical field [0001] The invention relates to a power monitoring system, in particular to an intelligent on-line monitoring and early warning system for cable operating conditions. Background technique [0002] Power cables are transmission cables laid underground in cities and are one of the most important components of the national grid infrastructure. With the acceleration of urbanization in my country, the coverage and asset scale of power cables are increasing at an unprecedented rate. [0003] In recent years, with the rapid development of power grids, more and more cables are used in urban power grids. Since the cable lines run underground, the environment in the cable tunnel, such as temperature and humidity, water quality and water level, harmful gases, etc., cannot be predicted on the ground. Therefore, the problems of fire prevention, gas prevention, explosion protection, waterproof and anti-theft of cable tunnels are becoming more and more important. In order...
