Problems solved by technology

Existing ground clamps can only be used when the bus bar is suspended or the spacing between the line bars is small. The space in the switch cabinet is narrow and the lead wires are arranged in different directions. ) when the ground wire needs to be suspended, the conventional ground wire clamp cannot be suspended because the direction of the clamp is perpendicular to the insulating rod, so that the technical measures to ensure the safety of the staff cannot be effectively implemented

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] as attached Figure 1-3 A grounding clamp suitable for use in a switch cabinet is shown, which includes an insulating rod 1, a clamp body fixed on the insulating rod 1, and a movable contact 4 arranged on the main body of the clamp. The main body of the clamp includes The beam 2, the static contact 3 arranged at one end of the beam 2, and the positioning column 8 arranged at the other end of the beam 2, the positioning column 8 is provided with a terminal 7 connected to the ground wire, and the terminal 7 is screwed on the positioning column 8 bolts to facilitate the connection of the ground wire. Before use, the ground wire needs to be connected to the positioning post 8 through the terminal post 7; figure 1 As shown, the main body of the wire clamp is generally U-shaped, and its opening direction is upward, which is consiste...

Abstract

The invention relates to a ground clip in a switch cabinet. The ground clip comprises an insulating rod, a clip main body fixed on the insulating rod, and a moving contact arranged on the clip main body, wherein the opening direction of the clip main body is consistent with the axis direction of the insulating rod; the clip main body comprises a cross beam, a fixed contact arranged at one end of the cross beam, and a locating pillar arranged at the other end of the cross beam; the locating pillar is provided with a binding post; a locating rod is fixedly arranged on the moving contact; the locating rod is sheathed on the locating pillar by a locating hole formed in the locating pillar; a pressure spring is sheathed on the locating rod. The ground clip can be used for carrying out ground wire connection operation on a knife-switch fixed contact and / or leads arranged in a balanced way along the transverse direction, and is convenient and fast and is capable of saving time and labor..

Description

technical field [0001] The invention relates to an electric power maintenance tool, in particular to a grounding clamp suitable for a switch cabinet. Background technique [0002] At present, when the power equipment is overhauled, hanging the ground wire is one of the measures to ensure safety. Existing ground clamps can only be used when the bus bar is suspended or the spacing between the line bars is small. The space in the switch cabinet is narrow and the lead wires are arranged in different directions. ) when it is necessary to hang the ground wire, the conventional ground wire clamp cannot be suspended because the clamping direction is perpendicular to the insulating rod, so that the technical measures to ensure the safety of the staff cannot be effectively implemented. [0003] In view of the above defects, it is necessary to invent a grounding clamp that can quickly and effectively ground the static contacts of the knife switch and / or the leads arranged in a horizon...
