Problems solved by technology

[0003] With the development of electric locomotives, high-voltage electrical appliances such as vacuum circuit breakers and high-voltage grounding switches have gradually changed from roof installation to cabinet installation. Therefore, vertical vacuum circuit breakers with smaller volume and lighter weight have been developed. The existing BTE structure The high-voltage grounding switch can no longer be used in conjunction with it

Abstract

The invention provides a grounding switch used for being matched with a vertical vacuum circuit breaker for usage. The grounding switch comprises a high-voltage conductive mechanism, a middle supporting mechanism, a transmission mechanism, a locking mechanism and a state feedback mechanism. The grounding switch is arranged on a line side cabinet skeleton. The high-voltage conductive mechanism comprises a rotary rod and a plurality of contact spring leafs, and the plurality of contact spring leafs are arranged on the rotary rod from top to bottom. The high-voltage conductive mechanism is used for conducting electricity, the middle supporting mechanism is used for supporting the high-voltage conductive mechanism and the transmission mechanism. The transmission mechanism is used for transmitting movements among parts. The locking mechanism is used for locking and limiting the high-voltage grounding switch to two limiting positions. The state feedback mechanism is used for feeding back states to a locomotive main circuit. The grounding switch is integrally arranged on the line side cabinet skeleton. By adopting the design, the grounding switch capable of being matched with the vertical vacuum circuit breaker for usage is realized. The invention further provides an electric locomotive comprising the grounding switch.

Description

technical field [0001] The present application relates to the technical field of electric locomotive equipment, and more specifically, relates to a grounding switch. The present application also relates to an electric locomotive comprising the above earthing switch. Background technique [0002] Most of the high-voltage grounding switches in the prior art are BTE series, which are used together with the L-shaped horizontal main circuit breaker, and are mostly installed on the roof of the vehicle, and are mainly divided into the exterior part and the interior part. It is widely used in electric locomotives such as HXD1, HXD1B, HXD1C, HXD1F, Tieba, Shenhua 8-axle and EMUs such as CRH1 and CRH3. [0003] With the development of electric locomotives, high-voltage electrical appliances such as vacuum circuit breakers and high-voltage grounding switches have gradually changed from roof installation to cabinet installation. Therefore, vertical vacuum circuit breakers with smaller ...
