Embodiment

[0022] like Figure 1-2 As shown, a single-pole isolating grounding switch includes: a mounting base 1, a pillar porcelain insulator 2, an outlet seat assembly 3, a linkage pull rod 4, a grounding pull rod 5, and a conductive rod 6.

[0023] The installation base 1 is installed on the top of a cement column or a steel support with a height exceeding 2 meters.

[0024] Porcelain bellows are arranged on the outside of the pillar porcelain insulator 2 . It includes a left pillar porcelain insulator 201 and a right pillar porcelain insulator 202, which are symmetrically arranged on the base 1 through a rotatable left bearing seat 203 and a right bearing seat 204 respectively; the bottom end of the right bearing seat 204 is connected with the flat key 7, and the flat key 7 is connected with rotating mechanism by a vertical bar.

[0025] The outlet seat assembly 3 includes a left outlet seat assembly 301 and a right outlet seat assembly 302. One end of the left outlet seat assembl...

Abstract

The invention relates to an isolated switch, in particular to a single-pole isolated grounding switch, and belonging to the field of a power device. The single-pole isolated grounding switch comprises an installation base 1, a support ceramic insulator 2, a wire outlet seat assembly 3, a linkage pull rod 4, a grounding pull rod 5 and a conductive rod 6. The single-pole isolated grounding switch is simple in structure and low in cost, grounding operation can be automatically fulfilled when the single-pole isolated grounding switch is switched off, and thus, the safety of the device is improved.

Description

technical field [0001] The invention relates to an isolating switch, which belongs to the field of electric equipment, in particular to a single-pole isolating grounding switch. Background technique [0002] Isolating switch (commonly known as "knife switch") generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch. The working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. The main feature of the isolating switch is that it has no arc extinguishing ability, and can only open and close the circuit under the condition of no load current. [0003] The structure of the single-pole isolating switch in the prior art is complicated, and the assembly of the outlet socket is not grounded when it is discon...
