Linear motion transmission structure for contact

Abstract

The invention relates to a linear motion transmission structure for a contact, which comprises a movable contact (1), a guide member (2) and a transmission shaft (3), wherein a pass-through sliding cavity is arranged in the guide member (2); the transmission shaft (3) penetrates through the sliding cavity to move back and forth; the movable contact (1) is located at one end of the sliding cavity;the movable contact (1) is movably connected with a relative position of the transmission shaft (3), and the other end is connected with a high-voltage bus and an insulating experimental device; whenthe transmission shaft (3) and the movable contact (1) are connected, the movable contact (1) is driven to move through the transmission shaft (3), thereby switching the test state of the high-voltagebus. Compared with the prior art, when the transmission shaft is connected with the movable contact in the invention, the movable contact is driven to move through the transmission shaft, the test state of the high voltage bus is switched, and random switch can be carried out between two states of a test phase and a grounding phase; meanwhile, the test process can be met only by manual operations, and a complex wiring operation is not needed; the occupied space is small; and the structure is simple.

Description

technical field [0001] The invention relates to a test tool for high voltage technology, in particular to a contact linear motion transmission structure. Background technique [0002] Contact transmission is an indispensable structure for high-voltage electrical products. In the 110kV GIS tooling, the busbar mainly uses a three-phase common box busbar, and then the A / B / C three-phase is closed through the moving contact. Most of the existing product moving contact transmission adopts mechanism transmission, and the design is complicated. Field test tooling requires small size, easy transportation, and easy operation. For each insulation test, the other two phases are grounded. The test process requires frequent phase change and wiring, which is cumbersome. [0003] After searching the existing technology, it is found that the existing mainstream manufacturers use 110kV GIS three-phase insulation test devices, and the internal transmission structure is in a state of technical...

Problems solved by technology

Most of the existing product moving contact transmission adopts mechanism transmission, and the design is complicated

Field test tooling requires small size, easy transportation, and easy operation. Every time one of the insulation tests is done, the other two phases are grounded. The test process requires frequent phase change and wiring, which is cumbersome.

[0003] After searching the existing technology, it is found that the existing mainstream manufacturers use 110kV GIS three-phase insulation test devices, and the internal transmission structure is in a state of technical blockade, which cannot be widely used
