Abstract

The present invention relates to the technical field of high-voltage power equipment, in particular to an outdoor high-voltage AC grounding switch with 1100KV opening and closing of super-B class induction current, including a main static contact, an auxiliary static contact, a main grounding knife, and a chassis , auxiliary moving contact, signal control box, arc extinguishing device, the main static contact and auxiliary static contact are arranged on the wiring board at the upper end of the switch, and the auxiliary moving contact is arranged on the side of the lower end of the active contact , the signal control box is provided with a switch, and the action of the main grounding knife rotating shaft drives the trigger device to trigger the switch of the arc extinguishing device. The present invention not only improves the safety performance of the grounding knife, but also has the advantages of simple and reasonable structure, stable transmission and high reliability. It effectively solves the problem of the induced current caused by the opening and closing of the 1100kV high-voltage AC grounding switch when the 1100kV grid frame is arranged with double-circuit lines on the same tower.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric equipment, in particular to an outdoor high-voltage AC grounding switch, in particular to an outdoor high-voltage AC grounding switch suitable for opening and closing ultra-B class induced current with a rated voltage of 1100KV. Background technique [0002] With the continuous expansion of the power grid and the continuous improvement of capacity, the structure of double-circuit parallel high-voltage transmission lines on the same tower is increasing day by day, and the requirements for the opening and closing induction current capability of the grounding switch are also getting higher and higher. The opening and closing induction current has become a part of the high-voltage grounding switch. special operating conditions. The principle is: in two or more overhead transmission lines arranged in parallel or adjacent to the same tower, when a certain line or several lines are powered ...
