Problems solved by technology
When carrying out cable high-voltage tests, the support and fixation of the cable terminal is a difficult problem. Usually, temporary fixation measures are taken in combination with the environment where the cable is located. Due to its own weight and the unreliability of the temporary fixing method, the cable is prone to shift and the insulation distance between the cable and the surrounding objects is insufficient, which brings unsafe factors to the high-voltage test

Embodiment Construction
[0013] The present invention will be further explained below in conjunction with the drawings:
[0014] see figure 1 , figure 2 , A cable terminal support device for high-voltage tests, the present invention is characterized in that: the cable terminal support is made of two semi-circular column cable clamping pieces 1, 1'made of high-strength insulating material, and is formed by buckling each other; The two buckling edges of the cable clamping piece of a semicircular column are provided with a bump on one side and a groove on the other. The two semicircular column cable clamping pieces are buckled by the convex block to the groove. One end surface of the ring-column cable clamping piece is located at the grooved end with positioning holes 2, and each semi-circular-column cable clamping piece is provided with positioning holes 2'on the bumps; two semi-circular-column cables After the clamping pieces are buckled with each other, two positioning pins 11 are inserted into the pos...

The invention provides a cable terminal bracket device for a high-potential test. The cable terminal bracket is formed through mutually buckling two semi-circle ring pillar cable clamps (1 and 1') both made of high-intensity insulating materials; two buckling edges of each semi-circle ring pillar cable clamp are provided with a convex and a groove respectively; and the two semi-circle ring pillar cable clamps are buckled through the manner that the convexes are buckled with the grooves. The cable terminal bracket provided by the invention has the characteristics of detachability, portability, simplicity and convenience for operation and strong adaptive capacity, and can meet the requirements of performing cable terminal high-potential tests under different environments.
Description
Technical field [0001] The invention relates to a cable terminal support device for a high voltage test, belonging to the technical field of high voltage tests. Background technique [0002] In the power system, power cables are widely used and large in number. In order to check the condition of the cable insulation, it is necessary to perform high-voltage tests on the cables newly installed, in operation, after fault repair and quality inspection. When carrying out the cable high voltage test, the support and fixation of the cable terminal is a difficult problem. Usually, temporary fixation measures are taken in accordance with the environment of the cable, such as using temporary wooden brackets for local materials to support or use insulating tape traction to fix the cable. Due to its own weight and the unreliability of temporary fixing methods, cable displacement is prone to cause insufficient insulation distance between the cable and surrounding objects, which brings unsafe ...
