Abstract

The invention discloses a demarcation circuit breaker device, comprising a high-voltage vacuum demarcation circuit breaker body and an intelligent protection terminal, wherein the high-voltage vacuum demarcation circuit breaker body is internally provided with a zero sequence current mutual inductor and two current transformers; a voltage transformer is arranged at the power side of the high-voltage vacuum demarcation circuit breaker body; the intelligent protection terminal arranged on a field distribution line comprises a protection device for protecting the distribution line and measuring the operation state of the distribution line and a GPRS communication module; the protection device is directly connected with the high-voltage vacuum demarcation circuit breaker body by an omniseal airproof aviation connector and an outdoor sealing cable, and is connected with the GPRS communication module by a serial interface; and the operation power and the voltage signals of the intelligent protection terminal and the high-voltage vacuum demarcation circuit breaker body are all provided by the voltage transformer. The invention can be widely used in 10kV and 13 kV overground ring network lines as a sectionalizer switch and an interconnection switch, and can implement an automatic switching device deployed by ring network load.

Description

technical field [0001] The invention relates to an automatic switch device which can be used as segmental isolation switch and contact switch in the overhead ring network line of power system 10KV, 13KV city and rural distribution network, and can implement ring network load allocation. As a boundary switch (commonly known as a watchdog), it is used as a recloser and a sectionalizer in the feeder overhead distribution network, especially a boundary circuit breaker device. [0002] The invention also relates to a remote monitoring method for boundary circuit breaker equipment. Background technique [0003] The electric power industry is a technology-intensive and equipment-intensive industry, and its unique production and operation methods determine its informatization development model. From the initial focus on the automatic monitoring / monitoring of power plants and substations, to the special application of power business, mainly involving the use of power grid dispatchin...
