Embodiment 1

[0021] Embodiment 1: The cable line is arranged in a cable trench under the ground, and the cable trench has an opening, and a manhole cover needs to be provided at the opening.

[0022] as attached figure 1 As shown, a cable line online monitoring system for real-time online detection of cable line status includes a detection device and an alarm device. The detection device is set at the cable trench where the cable line is located, and the alarm device is set at the automation master station which monitors the power grid. The detection device and the alarm device are connected through the Internet of Things, which can be wired or wireless.

Abstract

The invention relates to a cable line online monitoring circuit, and the system comprises a detection device and a warning device, wherein the detection device is connected with the warning device through the IOT (Internet of Things). The detection device comprises a water level detection sensor which is used for detecting the condition of the level of water in a cable trench and uploading a water level signal; a temperature and humidity detection sensor which is used for detecting the temperature and humidity of a cable joint in the cable trench and uploading a temperature and humidity signal; a cable fault collector which is used for detecting whether the cable joint of the cable in the cable trench has a fault or not and uploading a joint condition signal; a smoke alarm which is used for detecting the smoke condition in the cable trench and uploading a smoke signal; and an intelligent controller which is used for receiving the water level signal, the temperature and humidity signal, the joint condition signal and the smoke signal, combining preset information to obtain a fault signal for judging whether a cable line has a fault or not, and uploading the fault signal to the warning device. The warning device comprises an industrial control computer. The circuit provided by the invention reduces the labor intensity of a worker, improves the operation level of a power grid, and improves the power supply reliability and informationization level.

Description

technical field [0001] The invention relates to a system for on-line monitoring of cable lines. Background technique [0002] The grid is intricate and prone to failure. In particular, underground cable faults are difficult to find due to their hidden characteristics. Sometimes they have to check each section of the line one by one to determine the fault area, which is extremely unfavorable to the safety of the line and equipment operation, and manual line inspection is required, which increases fault finding. difficulty and time. Therefore, it is very necessary to upload the fault information collected by the intelligent cable cover control to the automatic master station system through new materials and new technologies, so as to realize the automatic positioning of the fault section. Contents of the invention [0003] The purpose of the present invention is to provide an on-line monitoring system for cable lines that can automatically detect and report faults of cable...
