Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0025] see Figure 1 to Figure 4 According to the pole switch of the present invention, it includes: a switch operating assembly and an insulating casing 13, and the insulating casing 13 is integrally injection-molded outside the operating assembly. In the insulating casing of the present invention, all the switch operation components are poured into the casing to realize full insulation, no harmful gas is used, and it is more environmentally friendly, safe and reliable.

[0026] see Figure 1 to Figure 4 , The switch operation assembly includes a static end conductive rod 1, a vacuum interrupter 2 and a moving end conductive rod 5, and the vacuum interrupter 2 is arranged between the static end conductive rod 1 and the moving end conductive rod 5....

Abstract

The invention provides a pole-mounted switch. The pole-mounted switch comprises a switching operation component and an insulating case. The insulating case is arranged outside the operation component by integral injection molding. The switching operation component is injection-molded in the case to achieve full insulation, no harmful gas is used, and accordingly the pole-mounted switch is more environment-friendly and safe and reliable.

Description

technical field [0001] The invention relates to the field of high-voltage electrical switch, in particular, to a pole-mounted switch. Background technique [0002] The original ZW20 inflatable switch is filled with sulfur fluoride gas with zero gauge pressure, which is not environmentally friendly and prone to air leakage. The original switch is placed at one end with a spring mechanism, and the arc extinguishing chamber is installed in the insulating box. Discharge problem, there is a potential safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide an on-column switch to solve the technical problem that the existing on-column switch uses sulfur fluoride gas, which is not environmentally friendly and easy to leak. [0004] To achieve the above object, the present invention provides a pole switch, which includes a switch operating assembly and an insulating housing, and the insulating housing is integrally injection molded out...
