Abstract
The invention relates to a method for connection and disconnection between a pair of high-voltage test tongs and a leading-out terminal of high-voltage equipment. The method is performed through a mechanical arm. The mechanical arm comprises a high-voltage test tong mechanical arm body, a telescopic insulated rod and a manual operation mechanism. The high-voltage test tong mechanical arm body, the telescopic insulated rod and the manual operation mechanism are connected into an operation integrity through a brake cable. Two tong legs of the pair of test tongs are placed in a limited manner through a fixed finger and a traction moving finger. When a handle is moved downwards, the tail end of a tong rotary frame welded piece is drawn to be close to the tail end of a tong fixed frame welded piece through traction of the brake cable, so that a clamping opening of the test tongs is opened; after the pair of test tongs is conveyed to the proper position, the handle is released, under the action of a torsion spring, the clamping opening of the test tongs is closed, so that a conductive terminal is clamped, and then the high-voltage test tong mechanical arm can be disengaged from the test tongs. By the adoption of the method for connection and disconnection between the pair of high-voltage test tongs and the leading-out terminal of the high-voltage equipment, the work efficiency can be greatly improved, and a reliable guarantee is provided for the safety of testing personnel.
