Abstract

The invention relates to an intermediate-voltage solid insulation switch and a purpose and mechanical drive device thereof. The intermediate-voltage solid insulation switch can monitor the voltage at two positions, and can be formed by single casting technology. A current sensor can detect the current through an insulation body and a switching component. The intermediate-voltage solid insulation switch has advantages compared with the prior art. The intermediate-voltage solid insulation switch can be used to monitor the operation state of the electrical network and reflect reliable operation data of the electrical network. The mechanical drive device of the intermediate-voltage solid insulation switch drives the switching component of the switch via a high-efficiency DC electromagnetic mechanism. The mechanical drive device uses a switching mechanism which is operated by DC electromagnetic exciters, and has a manual rapid opening / closing function selectively, and the manual rapid opening / closing function is unique in such switches. After manual operation, the mechanism automatically stores energy via current in a main loop.

Description

technical field

[0001] The invention relates to a hybrid insulator device for a medium-voltage power distribution network, and is suitable for the power distribution network. More specifically, it relates to a medium-voltage solid insulated switch and its application, a device for mechanically driving a medium-voltage solid insulated switch. Background technique

[0002] Distribution networks typically deliver electricity to consumers through the use of connected transmission lines, distribution buses, distribution feeders, and the like. Generally speaking, because electricity can be distributed through more than one path within the distribution network. Depending on the region and the availability of power resources, many power distribution network configurations provide consumers with power from two or more sources.

[0003] Electricity distribution networks face a common problem: If there is a momentary short circuit somewhere in the grid, there may be a brief interrupti...
