Abstract

The invention relates to a power grid automation isolation device including an isolation device body, utility poles and mounting rings. The isolation device body includes an isolation box, signal receiver, signal transmitter, controller, rotating electric machine, couplings, connectors, insulating sleeve, a first fixed contact and a moving contact, A low end of that utility pole is fixedly connected with a tapered plug rod, A loop groove is arrange at that upper end of the telephone pole, two mount rings are arranged on the outer side of the groove, both port of that two mounting ring are fixedly connected with connecting blocks, the two connecting blocks are provided with threaded holes, A fixing bolt is arranged on one side of the threaded hole, A fixing bolt is threadably connected withthe two connecting blocks through a threaded hole, Two mounting rings are spliced to form a ring, and the inner diameter of the ring is equal to the outer diameter of the groove on the telephone pole. The device adopts four fixed contacts and four movable contacts, and realizes the quick line switching through the contact of the fixed contacts and the movable contacts, thereby improving the overall adjustment efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of isolation equipment, in particular to an automatic isolation device for a power grid. Background technique [0002] In the new century, the status and role of the smart grid in the power distribution system are becoming more and more important, and it is an important part of the power distribution system. In the power system, the realization of the smart grid is to improve the reliability of the power supply system, improve the economic efficiency of the grid operation, and promote the operation efficiency, so as to realize the optimization and rational operation of the distribution network. At present, when mentioning the smart grid, people first think of the distribution network automation system. Feeder automation, as the key link of the current smart grid and grid automation system, has attracted widespread attention. However, due to the immature technology in this area in my country, there are still...
