Multi-parameter acquisition and anomaly prevention early warning method and application of substation cable channel

Abstract

The invention discloses a channel multi-parameter acquisition and anomaly prevention early warning method and application of a substation cable. The method comprises the following steps: 1, on-site data acquisition, current segmentation monitoring, system self-checking and troubleshooting, early warning model construction, polling early warning screening and early warning screening. The design isreasonable, data such as cable tunnel temperature, humidity, harmful gas, toxic gas, accumulated water level, fire smoke sensing and well lid displacement are collected in real time; state monitoringand real-time monitoring are realized; multi-parameter information exchange of cable channel operation is realized; once anomalies are found, an alarm is given instantly to a main station monitoring platform through a wireless autonomous network; fault positioning and desktop alarm services are automatically started, related operation and maintenance personnel are urged to process cable tunnel hidden dangers as soon as possible, a traditional periodic inspection mode is changed, the manual inspection cost and the fault occurrence rate of cable equipment are greatly reduced, the working efficiency and the power supply quality are improved, and the real-time monitoring, early warning, response and operation and maintenance level of a cable channel is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission detection, in particular to a multi-parameter acquisition and abnormality prevention and early warning method and application of a substation cable channel. Background technique [0002] In recent years, explosions and accidents in cable tunnels of power supply enterprises have occurred continuously. Many accidents have caused serious personal casualties, as well as major economic losses, and the social impact is relatively bad. Analysis of factors causing such vicious accidents mainly includes fire, explosion, falling to death, toxic gas and other aspects. For the operation and management of substation cables, relevant departments invest a lot of manpower and material resources every year to inspect the cables and the environment in the cable trench. Especially in high temperature and heavy load seasons, a large number of inspections are carried out, such as infrared temperature measu...

AI Technical Summary

Problems solved by technology

Especially in high temperature and heavy load seasons, a large number of inspections are carried out, such as infrared temperature measurement of the cable joints in the well trench, well cover safety anti-theft and anti-sabotage inspections, and water accumulation in the well trench, fire prevention observation and detection, etc., but these inspections are all It relies on manual inspections at the scene, and cannot effectively prevent and advance early warning, and has certain defects.
