Description

High voltage withstand voltage test wiring frame

technical field

The invention relates to the technical field of high voltage withstand voltage test.

Background technique

In the power system, high-voltage withstand voltage tests are often performed on transformers and other related equipment. This is to verify the insulation performance of the equipment, ensure the safety of the equipment in use, and prevent safety hazards such as leakage and leakage. The method of withstand voltage test is mainly to connect the high-voltage power supply and the equipment under test through wires and power on for a period of time. Because the test voltage is very high, it is necessary to keep a certain distance between the wire and the ground, otherwise high-voltage arc discharge may occur and cause danger. In the traditional test, the wires are usually suspended with insulated wires, or the wires are supported by insulating objects such as cardboard. These methods are neither safe nor convenient, and there are many problems.

In order to solve the above problems, the high-voltage withstand voltage test wiring bracket (Chinese Patent Publication No. CN203011953 U) invented by Che Zhichao et al. discloses a bracket. The wiring groove is Y-shaped and is provided with a spring tongue. An insulating support frame invented by Huang Shengxiong et al. for improving the arrangement of high-voltage leads in the AC withstand voltage test (Chinese Patent Publication No. CN203054017 U) discloses another insulating support frame. The device is characterized in that its bottom uses three legs To fix itself, the insulating rod can also be provided with clamps to clamp high-voltage wires. Above two patents are mainly to play the effect of supporting wire, and itself does not have wiring function, also there is certain inconvenience in use.
