The invention relates to a test tool for a wire soft shield cover. The test tool for the wire soft shield cover comprises a first support and a second support, and the second support is movably arranged inside a first support framework. According to the structure of the first support, metal bases are arranged at the bottom ends of supporting rods, cross beams are movably arranged at the upper portions of the supporting rods, a metal board is arranged on the upper surface of each cross beam, the ends of the metal boards are provided with electrodes, and first grooves are formed in the metal boards and the cross beams in a matched mode. According to the structure of the second support, a table board is arranged on supporting columns, fixing clips are arranged on the table board, the fixing clips are connected with one side of the table board in a rotating mode, and an elastic sheath is arranged on the table board and is matched with the shield cover. The test tool for the wire soft shield cover can be used for various experiments, the functions are complete, use is flexible, cost is lowered, the structure is simple, the practicability is high, safety and reliability are achieved, and the test tool has very high application and popularization value.
Description
technical field [0001] The invention relates to a test tool for a power system, in particular to a test tool for a soft shielding cover of a wire. Background technique [0002] At present, the special test bracket used in the high-voltage test cannot meet the test requirements. When making the power frequency withstand voltage of the soft shielding cover of the wire, the soft shielding cover of the wire is covered with copper shielding cloth, and at the same time, it is externally grounded. connected to high voltage. [0003] Problem: 1. When the existing test bracket is externally grounded, the copper shielding cloth cannot wrap the wire soft shield tightly. It means that the insulation assessment of the soft shielding cover of the wire is not enough. If the insulation is not good in the place where the wrapping is not tight, the test cannot find the problem, which will bring hidden dangers to the equipment. [0004] 2. Existing test brackets cannot meet the requirements...
