Embodiment Construction

[0024] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the implementation manners of the present invention, all other implementation manners obtained by those of ordinary skill in the art without any creativity fall within the protection scope of the present invention.

[0025] The grounding switch in this embodiment is a grounded vacuum interrupter, on which a transmission mechanism of the grounding switch is provided. The transmission mechanism of the grounding switch includes a base plate 9, a transmission device, a locking device, an energy storage spring 1, a grounded output shaft 8 .

[0026] One end of the energy storage spring 1 is connected with the isolation shaft 10, and the rotation of the isolation shaft 10 in the forward and reverse directions drives t...

Abstract

The invention belongs to the technical field of power switch devices, and particularly relates to a grounding switch transmission mechanism which comprises a substrate, a transmission device and a locking device. The transmission device is arranged on the substrate and in transmission connection with a grounding output rotating shaft and drives the grounding output rotating shaft to rotate forwards and backwards under the action of an energy storage spring, so that a grounding switch is opened and closed, and forward and backward rotation of a separation rotating shaft drives the energy storage spring. When the grounding switch is in an opening state, opening of the grounding switch is locked by locking the transmission device. When the grounding switch is in a closing state, closing of the grounding switch is locked by locking the transmission device. The grounding switch transmission mechanism is simple in structure, and opening and closing positions of the switch can be locked.

Description

Technical field [0001] The invention belongs to the technical field of power switch equipment, and specifically relates to a transmission mechanism of a grounding switch. Background technique [0002] At present, the grounding switch on the market uses an isolated switch for closing. The disadvantage is that the contacts are easily ablated when the grounding is closed, and metal particles are ionized, which pollutes the internal environment of the sealed box, and affects the flow capacity and insulation level of the main circuit. . In order to improve the closing ability, a grounded vacuum interrupter with high grounding closing ability is generally used, which often increases the cost of the entire switchgear. [0003] In order to solve the above problems, the applicant of the present application proposed a dual interrupter grounding switch, in which the dual interrupter grounding switch adopts an isolated and grounded three-station mechanism to make the grounded vacuum interrupt...
