Problems solved by technology

In the event of pressure loss, electrical equipment failure, etc., it is easy to cause water inflow failure to block the equipment in the well, and the oil pressure signal cannot be sent normally.
If oil leakage occurs in the cable at this time, the signal cannot be sent normally, and pressure supplement measures cannot be taken, which will directly lead to line failure

Abstract

The invention relates to an oil-filled cable stop well monitoring system, which comprises a stop well information acquisition device and a monitoring platform connected mutually, wherein the stop well information acquisition device is arranged in the oil-filled cable stop well and comprises a power supply assembly and a stop well information acquisition assembly and a signal converter connected with the power supply assembly; the stop well information acquisition assembly comprises an oil pressure sensor connected with the oil-filled cable, a water level sensor arranged at the bottom of the stop well, a Hall current sensor connected with the power supply module and a temperature sensor connected with an oil-filled cable joint and a grounding bar; and the oil pressure sensor, the water level sensor and the Hall current sensor are connected with the monitoring platform via the signal converter respectively. Compared with the prior art, the oil-filled cable stop well monitoring system has the advantages of immersion prevention, thorough detected signals, theft prevention, strong signals, wide distribution and the like.

Description

technical field [0001] The invention relates to the field of power cable monitoring, in particular to a monitoring system for oil-filled cable plug wells. Background technique [0002] With the rapid growth of the country's economy in recent years, the requirements of all walks of life for the electric power market have also been increasing. For the daily inspection of the cable plugging well in the power supply link, management and maintenance personnel can only rely on driving inspections, which is a waste of manpower. The work efficiency is low again, and the abnormal situation cannot be found in time, so it is difficult to grasp the operation status in time. [0003] Oil pressure monitoring sensors have been installed at each detection point of the original super-oil-filled oil-filled cable, but there is a lack of monitoring of water level and monitoring of illegal intrusion of plugged wells. In addition, there is a lack of an integrated management platform to monitor eq...
