Demand Analysis
In recent years, the demand for electricity has been rising, and the requirements for the operation and management of high-voltage power cables have become higher and higher. Control of cable sheath ring current is a very important part of the cable energized operation, abnormal ring current will lead to high temperature heating and other phenomena, accelerate the aging of the insulation layer, shorten the life of the cable. In view of this phenomenon, in order to improve the safety of cable operation, Dinstar Intelligent Technology has developed a cable sheath ring current online monitoring device, which can accurately reflect the actual operating status of the equipment, detect hidden equipment problems in advance, and reduce accidental losses.
the principle of work
Cable sheath ring current online monitoring device can detect the ring current data of the grounded cable in real time, and transmit the data to the monitoring center in real time through fiber optic and 4G / GPRS / RJ45, the monitoring center shows the specific location on the electronic map, so that the line maintenance personnel can grasp the operation of the cable at any time.
