Description

Technical Field

[0002] Power safety tools are divided into three categories: insulating safety tools, general protective safety tools, safety fences (nets) and signs. Among them, basic insulating safety tools refer to tools that can directly operate live equipment, touch or may touch live objects, such as capacitive testers, insulating rods, insulating partitions, insulating covers, portable short-circuit grounding wires, personal safety grounding wires, phase detectors, etc.; the insulating rods of power equipment are used to isolate and support electrical conductors in power lines, playing the role of insulation and support. The insulation performance of insulating rods directly affects the normal operation of power equipment. Insulating rod detection can promptly detect defects and faults in insulating rods, and take repair measures in time to ensure the normal operation of equipment and safe power supply of lines.

[0003] In the prior art, the electrical properties of the insulating rod are tested to determine whether it is normal. The electrical test can be performed using equipment such as a high-voltage generator and an insulation resistance meter. Generally, a DC high voltage is required for testing. In actual operation, the testing device is fixed and cannot test insulating rods of different lengths. In addition, the test is dangerous. When the insulating rod is in a lower position, it is easy to touch other equipment, resulting in poor applicability. Therefore, we propose a testing device for power safety tools to solve the above problems. Utility Model Content
