[0002] In recent years, due to the needs of economic development, outdoor pole switches have been successfully applied to power systems with their simple structure, few parts, high reliability, precision, long service life, environmental protection, and stable electrical signals. At present, outdoor pole switches are developing in a diversified direction, and the disclosure of numerous patent technologies has promoted the continuous improvement of outdoor pole switch technology. Although these patent technologies are relatively advanced, they are difficult to meet the requirements of continuous operation when used in typhoons, humidity, etc., which has become the main crux of the current products. The existing technology design is large in size, which wastes raw materials, is cumbersome and wastes labor, and the live body is exposed, which poses a great safety hazard to line operation. It is easy to have excessive resistance in the conductive circuit for a long time due to long-term rain and ultraviolet and air corrosion outdoors, causing heating and line accidents, and equipment operation safety. Summary of the invention

[0003] In order to solve the above-mentioned problems, the present invention proposes: a fully insulated touchable high-voltage switch on an outdoor pole, comprising an inner cone incoming line, a high-voltage switch, a metal shell and an inner cone outgoing line, wherein the metal shell is equipped with a high-voltage switch, and the high-voltage switch is connected to the inner cone incoming line and the inner cone outgoing line.

[0004] Furthermore, the high-voltage switch is connected to the inner cone input line through a primary connecting line.

[0005] Furthermore, the high-voltage switch is connected to the inner cone outlet line through a primary connecting line.

[0006] Furthermore, the inner cone incoming line is connected to an external device via an incoming line cable 1.

[0007] Furthermore, the inner cone outlet wire is connected to an external device via an outlet cable.

[0008] Furthermore, a pressure relief device is installed in the metal shell.

[0009] The beneficial effects of the present invention are as follows: the present invention solves the problem that the original outdoor pole-mounted switch is affected by extreme weather such as typhoons and humidity, which affects the operation of the line, or endangers the safety of life and property. Even if the outgoing line is soaked in rainwater, it will not be unsafe and the equipment can still operate; the present invention solves the difficulties in the industry and meets the requirements by its own technology; the use of the present invention can reduce the probability of damaged parts, reduce space, increase reliability and make the operation safer and more stable.
