Abstract

The invention relates to a cable fault treatment system in a power system, in particular to an automatic emergency oil supply system of an oil-filled cable. The oil supply system comprises an oil-filled cable and a plurality of groups of common pressure tanks connected with the oil-filled cable. One port of the common pressure tanks is connected with an electromagnetic valve and the other port is connected with an oil pressure transmitter; a cable fault diagnosis automation device is connected between the electromagnetic valve and the oil pressure transmitter; the other port of the electromagnetic valve is connected with a standby pressure tank. By adopting the technical solving proposal, the problem of protection oil leakage caused by fault during the immediate compensation of the oil-filled cables is totally solved, thereby reducing fault danger coefficient, improving rescue efficiency in the oil leakage accident of the oil-filled cables, winning valuable time for power recovery and providing safety measures for rescue personnel.

Description

technical field [0001] The invention relates to a cable fault processing system in a power system, in particular to an automatic emergency oil supply system for an oil-filled cable. Background technique [0002] Most oil-filled cables have been in operation for a relatively long time, and there are many auxiliary equipment such as oil lines. After a certain period of operation, the oil line equipment is prone to burst at weak points, causing oil leakage, which directly threatens the safety of power cable lines. At the same time It also constitutes a direct danger to the personnel participating in emergency repairs. [0003] At present, after the oil-filled cable discovers the oil leakage accident, it is impossible to arrive at the accident scene for rescue at the first time. It can only start to troubleshoot after a period of time after the oil leakage accident is discovered. There is no set of automatic control oil at the site. The pressure compensation device and system a...
