Embodiment 1

[0014] attached figure 1 For the convenience of explanation, the connection terminal part is partially cut-away. as attached figure 1 As shown, the detection system includes a railway switch pole 1, a male end pressure detection rod 3, a female end pressure detection rod 6, a tapered gasket 2, a female end pressure detection rod 6 and the static end of the railway switch pole 1 Connection, between the inner cone surface 6.1 of the female pressure-resistant detection rod 6 and the outer cone surface of the static end of the railway switch pole 1 is a conical sealing gasket 2, and the male pressure-resistant detection rod 3 and the moving end of the railway switch pole 1 Connection, between the outer cone surface 3.3 of the male pressure-resistant detection rod 3 and the outer cone surface of the moving end of the railway switch pole 1 is a tapered sealing gasket. The connecting copper terminal 5 of the female withstand voltage detection rod 6 is connected with the copper term...

Embodiment 2

[0021] The material of the insulating layer is epoxy resin. The connecting part of the conductive rod and the insulating layer is first sandblasted, then ultrasonically cleaned and dried, then sprayed with a semi-conductive layer, and finally installed in the mold, and the epoxy resin is cured into an insulating layer through a vacuum pressure gel process.

[0022] All the other are with embodiment 1.

Abstract

The invention relates to the field of high-voltage electrical equipment, in particular to a voltage-withstanding detection tool of a railway switch polar column. The detection tool comprises a conductive rod, an insulating layer and a flange. An insulating layer is arranged at the outer layer of the conductive rod; a high-voltage joint is arranged at one end of the conductive rod; and the other end of the conductive rod is arranged at a male-head voltage-withstanding detection rod flange or a female-head voltage-withstanding detection rod flange. The conductive rod is connected to a polar column copper terminal through a connecting copper terminal. A semiconductive layer is arranged between the conductive rod and the insulating layer. The thickness of the semiconductive layer is 0.1 to 0.2mm. The insulating layer is made of a polytetrafluoroethylene material. With the detection tool, a problem that the railway switch polar column can not be detected directly due to the high voltage issolved. According to the detection tool, the electrical service life is prolonged and the tool size is reduced by the semiconductive layer and the skirt.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment, in particular to a voltage-resistant detection tool for railway switch poles. Background technique [0002] With the continuous development of China's economy, railway transportation is playing an increasingly active role in the important means of transportation in China. China's railway construction will enter a golden period, and high-speed rail and bullet trains have become the main means of transportation for travel. The safety and reliability of traction substations that provide power for electrified locomotives are also becoming more and more important. With the advent of the high-speed rail era, they are facing increasingly strong market demand. my country's railway traction voltage is 27.5kV. Quality inspection of railway switch components and complete sets of products is required during the production process. Due to the high voltage, there are potential safety hazards ...
