Problems solved by technology

This problem can sometimes cause serious damage, such as breaking post insulators and similar accidents, reducing the reliability and safety of equipment
However, it is actually very difficult to solve this problem by simply enlarging post insulators on high-current and high-voltage disconnectors, so that the above-mentioned technical solution of "(High-voltage disconnector contact assembly" cannot fully play its technical role.

Abstract

The invention relates to a dual-column horizontal rotation type high-voltage isolation switch, which is a switch device for isolating a powered device and a power-off device in a power system; the dual-column horizontal rotation type high-voltage isolation switch comprises two post insulators which are supported on a base and a cross pull rod which is arranged between the two post insulators, and is characterized in that the dual-column horizontal rotation type high-voltage isolation switch further comprises a position changing transmission mechanism which is supported on a flange shaft at the top part of the post insulator at the driving side, the transposition transmission mechanism is connected with a main contact by penetrating a conductive arm by a transmission rod; a position limiting trip is supported on the flange shaft at the lower end of the post insulator at the driving side, and the position limiting trip is hinged with the cross pull rod. The dual-column horizontal rotation type high-voltage isolation switch realizes that the opening and closing operation of the high-voltage isolation switch is completed by two steps, thus effectively lowering the transverse impact which is generated at the instant of the opening and closing operation of the isolation switch and further improving the overall reliability and the safety of the isolation switch.

Description

Technical field: [0001] The invention relates to a double-column horizontal rotary high-voltage isolating switch, which is a switchgear for isolating electrified equipment and power-off equipment in a power system. Background technique: [0002] The high-voltage isolating switch is a switching device used in the power system to separate and close the circuit with voltage and no load. On the open point, the high-voltage isolating switch can reliably pass the normal working current and withstand the short-circuit fault current in the closed state. In addition, the cooperation between the high-voltage isolating switch and the high-voltage switch can also change the load operation mode of the power grid. High-voltage isolating switch is the most used power equipment in the power system, and most of them are used outdoors [0003] In the existing equipment technology, take GW4 or GW14 disconnector as an example, they all include at least one phase switch body and an operating me...
