Embodiment 1

[0051] Such as Figure 1-7 As shown, the present invention discloses a grounding switch, which includes a bottom plate assembly 1 , a rotating rod assembly 2 and a drive assembly 3 .

[0052] Wherein, the rotating rod assembly 2 is provided with a reed assembly 201 that can be electrically connected with the vacuum circuit breaker, the number of sets of the reed assembly 201 is 2, and each set of reed assemblies 201 includes 2 reeds 20101 and a fixed block 20102 , the fixed block 20102 is installed on the rotating rod assembly 2, and two reeds 20101 are installed on the fixed block 20102. The two sets of reed assemblies 201 correspond to the input end and the output end of the vertical vacuum circuit breaker respectively.

[0053] The driving assembly 3 is installed on the bottom plate assembly 1, and the driving assembly 3 can drive the rotating rod assembly 2 to rotate, so that the rotating rod assembly 2 can rotate to the working position or the grounding position.

Embodiment 2

[0056] In the second embodiment provided by the present invention, the structure of the grounding switch in this embodiment is similar to the structure of the grounding switch in the first embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0057]In this embodiment, it is specifically disclosed that the drive assembly 3 includes a cylinder body 301 , a rack shaft 302 , a drive shaft 303 and a gear 304 . Both ends of the cylinder body 301 are sealed by a left end cover 30101 and a right end cover 30102 respectively.

[0058] Wherein, the rack shaft 302 is installed in the cavity of the cylinder body 301 and arranged laterally along the cavity of the cylinder body 301 . The driving shaft 303 is installed on the cylinder body 301 , and the driving shaft 303 is connected with the rotating rod assembly 2 . The gear 304 meshes with the rack shaft 302 , and the gear 304 is installed on the driving shaft 303 . The movement of the rack...

Abstract

The invention discloses a grounding switch which comprises a bottom plate assembly, a rotary rod assembly and a driving assembly. Reed assemblies which can be electrically connected with vacuum circuit breakers are arranged on the rotary rod assembly; the driving assembly is mounted on the bottom plate assembly, and the rotary rod assembly can be driven by the driving assembly to rotate to reach working positions or grounding positions; the driving assembly mounted on the bottom plate assembly can be driven when grounding is required, so that the rotary rod assembly can be driven by the driving assembly to rotate to reach the grounding positions, and the vacuum circuit breakers can be electrically connected with the reed assemblies arranged on the rotary rod assembly; the driving assemblymounted on the bottom plate assembly can be driven when the rotary rod assembly needs to rotate to reach the working positions, so that the rotary rod assembly can be driven by the driving assembly torotate to reach the working positions. The grounding switch has the advantages that the rotary rod assembly can be driven by a driving device to turn to the working positions or the grounding positions, accordingly, handle operation spaces in a tank can be omitted, manual operation can be omitted, the difficulty in designing the tank where the grounding switch is located can be lowered, and operation on the grounding switch can be facilitated.

Description

technical field [0001] The invention relates to the technical field of high-voltage grounding equipment for AC electric locomotives and EMUs, in particular to a grounding switch. Background technique [0002] At present, AC electric locomotives and EMUs generally use manual high-voltage grounding switches, and the commonly used ones are installed in boxes. The high-voltage grounding switch installed in the box needs enough space for the handle to operate, which affects the sealing design of the high-voltage electrical box to a certain extent, and increases the difficulty of the design of the box. In addition, manual operation is required, which is inconvenient to operate. [0003] Therefore, how to reduce the design difficulty of the box where the grounding switch is located and facilitate the operation of the grounding switch is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the object of the pr...
