Example Embodiment

[0023] The environmental protection novel pre-installed vacuum load switch/vacuum circuit breaker pole of the present invention, its preferred specific embodiment is:

[0024] It includes an assembled shell composed of a cover plate and an insulating shell, a vacuum interrupter is fixed between the cover plate and the insulating shell, one end of the vacuum interrupter is connected with the insulating pull rod, and the other end is connected with the static end bus through screws They are fixed together on the insulating housing, and the insulating housing is provided with a moving-end busbar outlet on the side wall of the corresponding end of the insulating tie rod.

[0025] Two ends of the vacuum interrupter are respectively provided with convex parts, wherein the convex part at one end is connected with the insulating pull rod, and a copper gasket is provided between the convex part at the other end and the static end bus bar.

[0026] The outer end of the insulating pull rod is connected with the joint bearing.

[0027] The insulating shell adopts a thin-walled structure, and the material of the insulating shell is reinforced polycarbonate.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 to Figure 4 As shown, the environmentally friendly new pre-installed vacuum load switch/vacuum circuit breaker pole of the present invention has the following advantages:

[0030] 1. The material of the pole shell is changed to degradable material;

[0031] 2. The cost of the material is lower than the cost of epoxy resin;

[0032] 3. The poles of the new environmentally friendly vacuum circuit breaker are combined, with large internal space and good heat dissipation;

[0033] 4. The pole column of the new environmentally friendly pre-installed vacuum circuit breaker is a lightweight design;

[0034] 5. Assembled design, good interchangeability.

[0035] The environmentally friendly new pre-installed vacuum load switch/circuit breaker pole of the present invention can solve the environmental pollution caused by the abandonment of the existing solid-sealed pole and improve the recyclability of the pole.

[0036] The pole is a pre-installed structure, the busbar at the moving end, the busbar at the static end, the vacuum interrupter, and the insulating pull rod are all separable, with high interchangeability, improving the utilization rate of product components.

[0037] The insulating material of the insulating shell of the pole is reinforced polycarbonate.

[0038] The pole is thin-walled to increase enough space for internal components.

[0039] The inside of the pole is supported by a semicircular structure that matches the semicircle of the cover plate, so as to fix the vacuum interrupter and at the same time have an insulating effect.

[0040] The pole adopts a semi-cylindrical shape, which can save materials, reduce weight, increase installation space, and have beautiful craftsmanship.

[0041] The fixed position of the busbar at the static end at the bottom of the pole adopts a boss structure, which can effectively improve the partial discharge.

[0042] The cylindrical boss at the bottom of the pole is used to solve the insulation problem caused by the process hole for installing the arc extinguishing chamber.

[0043] The bosses at the upper and lower positioning holes of the pole ensure the levelness of the pole installation.

[0044] The remaining poles are designed to be reinforced and weight reduction is considered.

[0045] To sum up, the pole column of the invention adopts the pre-installed type as a whole, and the whole is assembled type, without sealing, and has good heat dissipation. The insulating shell is different from the traditional epoxy resin, which eliminates the possibility that the insulating shell cannot be degraded. At the same time, the pole is pre-installed, and the components are highly interchangeable, which improves the utilization rate of finished products. It has the advantages of high maintenance and high reliability, and also has the advantages of low cost and light weight.
