[0002] In recent years, due to the needs of economic development, outdoor pole switches have emerged. With their simple structure, few parts, high reliability, precision, long service life, environmental protection, and stable electrical signals, they have been successfully applied to power systems. 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 operating requirements when a maintenance requires obvious fracture technology requirements. The current technology is an external isolation knife, which is large in size and wastes raw materials, cumbersome and labor-intensive. 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, causing heating and line accidents, and equipment operation safety. One is a built-in isolation, but the distance between the isolation blades is small, which is difficult to observe during maintenance and easy to misoperate, causing equipment damage and operator safety.

[0013] Example 1

[0014] In order to make the technical means adopted by the present invention and the purpose achieved easy to understand, the present invention is further explained in combination with a specific implementation method below. A removable column-mounted switch with a self-contained safety break includes a mobile switch, a high-voltage switch 3, a moving contact 4, a static contact 5 and a shell 6. The mobile switch is connected to the high-voltage switch 3. The part of the mobile switch connected to the high-voltage switch 3 is movably arranged in the shell 6, and the other part of the mobile switch passes through the shell 6 to the outside. The high-voltage switch 3 is arranged in the shell 6, and the high-voltage switch 3 is connected to the static contact 5 on the shell 6 through the moving contact 4.

[0015] The mobile switch includes a carrier vehicle 1 and a swing-in mechanism 2 . The carrier vehicle 1 is disposed in a housing 6 , and one end of the swing-in mechanism 2 is connected to the carrier vehicle 1 .

[0016] The other end of the swing-in mechanism 2 passes through the shell 6 to the outside.

[0017] Wherein, a high-voltage switch 3 is provided on the carrier vehicle 1 .

[0018] The carrier vehicle 1 is movably disposed in the housing 6 .

[0019] The stationary contact 5 on the housing 6 is connected to an external device.

[0020] Example 2

[0021] A removable column switch with a self-contained safety break. The purpose of the present invention is to overcome the above shortcomings and defects and provide a removable column switch with a self-contained safety break which has a smaller volume, a simpler structure, saves materials, has high reliability, is maintenance-free and is easy to operate.

[0022] To achieve the above object, the present invention adopts the following technical solution:

[0023] A removable column switch with a self-contained safety break, such as Figure 1-Figure 2 As shown, it includes a carrier 1, a swing-in mechanism 2, a high-voltage switch 3, a moving contact 4, a stationary contact 5, and a housing 6;

[0024] The housing 6 contains a high-voltage switch 3, which is placed on a carrier 1. The carrier 1 is driven by a rocking mechanism 2 to move the high-voltage switch 3.

[0025] After the static contact 5 and the moving contact 4 of the high-voltage switch 3 are connected, the terminal at the static contact 5 is connected to the external cable;

[0026] The contact position and isolation position of the high-voltage switch 3 can be clearly known by the position of the swing-in mechanism 2;

[0027] The switch cannot be moved when closed and can only be operated when open;

[0028] The isolation position is the maximum separation position of the static contact 5 and the moving contact 4; the contact position is the position where the moving contact 4 and the static contact 5 are connected and conducted.

[0029] The metal shell 6 is formed in one step, without deformation and water leakage; the inlet and outlet are installed with inner cone sleeves, which are well sealed to ensure no water leakage;

[0030] The above-mentioned metal shell 6 has an explosion-proof device, which can ensure the safety of the operating personnel when a fault occurs;

[0031] The present invention solves the key technology of the original outdoor pole switch isolation fracture. The position isolation knife is prone to rust after a long time and cannot be operated; the built-in isolation is not easy to observe, and the small distance often causes misoperation and line-out accidents. This endangers the safety of life and property. The present invention solves the industry difficulties. The use of this technology can reduce the probability of damaged parts, reduce space, increase reliability and make the operation safer and more stable.
