Abstract

The invention relates to the field of monitoring and protecting of transformer station cable trenches, specifically to a transformer station cable trench monitoring apparatus, and the invention improves conventional cable trench monitoring systems. The transformer station cable trench monitoring apparatus comprises monitoring terminals, a local work station, a monitoring video hard disc server, and an application server. Each of the monitoring terminals comprises a monitoring box, a monitoring camera arranged outside the monitoring box, and monitoring sensors and an information acquisition unit which are arranged inside the monitoring box, wherein the information acquisition unit is connected with the local work station through a 485 bus; the monitoring sensors comprise a temperature and humidity sensor, a smoke sensor, and a liquid level sensor; and a video communication line and a control line of the monitoring camera are connected with the monitoring video hard disc server. The local work station and the monitoring video hard disc server are in connection and communication with the application server through the Ethernet. The transformer station cable trench monitoring apparatus is simple and reasonable in structure. A layered, classified, and modularized technical scheme is provided for monitoring and protecting of the transformer station cable trenches, and the technical scheme is good in security, strong in anti-interference capability, and high in stability.

Description

technical field [0001] The invention relates to the field of monitoring and protection of cable trenches in substations, in particular to a monitoring device for cable trenches in substations that can improve the comprehensive monitoring and protection capabilities of cable trenches in substations. Background technique [0002] The cable trenches are criss-crossed, the cables in the trenches are dense, and the environment is dangerous, which is not convenient for manual real-time monitoring. In order to detect flammable, toxic and harmful gases, prevent the intrusion of criminals, and ensure the safety of power transmission and distribution lines. Generally, several monitoring points are set in the cable trench, and each monitoring point is equipped with several sensors to form a distributed monitoring cable trench monitoring system. However, due to the complexity of the underground conditions of the cable trench and the high requirements of the sensors at the monitoring po...
