Outdoor alternating-current high-voltage isolation switch and isolation switch system thereof

Abstract

The invention relates to the technical field of electric power, in particular to an outdoor alternating-current high-voltage isolation switch and an isolation switch system thereof. The outdoor alternating-current high-voltage isolation switch comprises a plurality of field branch control units formed by a plurality of channels, a master station communication unit, a remote communication looped network optical fiber and a control center, wherein the field branch control units are in signal connection with the master station communication unit; the master station communication unit is connected with the remote communication looped network optical cable; the remote communication looped network optical cable is connected with the control center. By adopting the outdoor alternating-current high-voltage isolation switch and the isolation switch system, the behindhand manner of walking to the field to operate on the spot can be replaced, so that the power cut and transmission time is greatly shortened, the labor intensity is reduced and the personal safety of workers is ensured; the isolation switch is compact in structure, good in using effect, low in manufacturing cost and high in response speed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an outdoor AC high-voltage isolating switch and its isolating switch system. Background technique [0002] Isolation switch (disconnector), that is, when it is in the divided position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; when it is in the closed position, it can carry the current under normal circuit conditions and abnormal conditions within the specified time ( For example, the isolating switch (commonly known as "knife switch") of the switching equipment under the current of the short circuit generally refers to the high-voltage isolating switch, that is, the isolating switch with a rated voltage of 1kV and above, usually referred to as the isolating switch, is a high-voltage switching device. One of the most used electrical appliances, its working principle and structure are relat...

AI Technical Summary

Problems solved by technology

At present, during the use of isolating switches, most of them need to be manually disconnected, and each site needs to be equipped with personnel, which increases the labor intensity. At the same time, the structure of the isolating switch is complicated, the maintenance cost is high, the manufacturing cost is high, and the use effect Difference
