Problems solved by technology

In the prior art, there is also a method of setting an arc striker on the contact seat to guide the arc to the arc striker so as to avoid the contact fingers on the contact seat from being affected by the arc. In this way, it is necessary to set a corresponding fixed structure on the contact seat and the arc starting part under the premise of meeting the requirements of the electric field, resulting in the problem of complex structure of the contact seat

Embodiment Construction

[0034] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0035] Specific embodiments of the switchgear of the present invention, such as Figure 1 to Figure 3 As shown, the switchgear includes an isolation and grounding combination switch A, and the isolation and grounding combination switch A includes an isolation switch mechanism and a grounding switch mechanism. The grounding switch mechanism includes a grounding switch movable end contact base 1, a grounding switch static end contact base assembly 2 and a grounding switch contact rod 3. The grounding switch static end contact base assembly 2 includes a grounding switch static end contact base 21 and a grounding switch static end contact base shield 22 sheathed outside the grounding switch static end contact base 21. The static end contact base 21 of the grounding switch is cylindrical, and an inner hole for inserting the contact rod 3 of the grounding switch is arran...

Abstract

The invention relates to a touch base assembly, a ground switch, an isolated ground combination switch and switch equipment. An arc striking ring is arranged on the hole edge of a jack of a touch base of the ground switch of the isolated ground combination switch in the invention, and when a touch rod is adaptively plugged with the touch base, the touch rod firstly gets close to the arc striking ring, so that an arc is generated on the arc striking ring, and touch fingers on the touch base are avoided from being ablated by the arc to influence the electric conduction performance. The arc striking ring is directly pressed through a closed structure of a shielding case on the touch base or is pressed on the hole edge of the jack of the touch base through a force transfer piece, and the problem that the structure of the touch base assembly is complex caused by the fact that the arc striking ring is fixed by additionally setting a fixed structure and a fixed piece is avoided.

Description

Technical field [0001] The invention relates to a contact base assembly, a grounding switch, an isolation grounding combination switch and switch equipment. Background technique [0002] The isolation and ground combination switch integrates the ground switch and the isolation switch into a switch structure, which reduces the number of components of the switch mechanism and reduces the cost. The isolation and grounding combination switch includes a grounding switch contact rod and a grounding switch contact seat. The contact seat of the grounding switch is provided with a shielding cover to make the electric field uniform at the insertion position of the contact rod and the contact seat. The contact rod is on the arm during use. It can make conductive contact with the contact seat under the driving of the contactor. During the contact between the contact rod and the contact seat, since the two are at different potentials, an arc is easily generated between the two, and the contac...
