Auxiliary device of cable test

Abstract

The invention relates to an auxiliary device of cable test, and belongs to the field of mechanical structures. The auxiliary device comprises a joint insulation layer, a threaded joint, a cable lug, an auxiliary terminal, a T type joint and a terminal insulation layer; the joint insulation layer wraps the threaded joint, one end of the threaded joint is provided with a threaded hole, and the end portion of the cable lug is fit to the end portion of the threaded hole; the auxiliary terminal cooperates with the threaded hole; and the cable lug is in clamp connection with the T type joint, and the terminal insulation layer wraps the T type joint. According to the auxiliary device of 10kV cable test, the operation space is increased to overcome problems that terminals are short and small and the operation space is narrow in original grounding test, and thus, operation staff can improve the working efficiency and safety effectively.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and more specifically relates to a cable test auxiliary device. Background technique [0002] During the implementation of the 10 kV cable test, it is often encountered that the connection between the test line and the cable core of the outdoor terminal head of the 10 kV cable distribution box is difficult and not firm, which not only affects the work progress, the safety of the test work and the accuracy of the test data, but also affects the accuracy of the test data. It will cause irreparable damage to the accessories of the outdoor terminal head of the 10 kV cable, leaving hidden defects and affecting the safe and stable operation of the cable. And the grounding test terminal is relatively short and small, placed in the T-shaped joint hole, which is not convenient for the lap connection of the test line, increases the work difficulty of the staff, reduces work efficiency and rush repair t...
