Embodiment Construction

[0021] Best practice:

[0022] Refer to attached figure 1 , attached figure 2 And attached image 3 , the lead wire clip device for live disconnection, including a first clip body 1 and a second clip body 2; the first clip body 1 is an inverted "T"-shaped structure, with a through hole 3 on the top, and the outer wall of the through hole 2 Two screw holes communicating with the through hole 3 are arranged on the top, and bolts 4 are screwed in from the outside to the inside respectively in the two screw holes, and the lower bottom has a semi-circular groove; The semi-circular arc groove on the clamp body corresponds to the semi-circular arc groove. After the two are combined, a circular hole 5 is formed. The through hole 3 is a smaller hole, and the circular hole 5 is a larger hole; the first clamp body 1 One shoulder side of the second clamping body 2 is a hinge member 6 , and the other shoulder is provided with fasteners connecting the first clamping body 1 and the secon...

Abstract

The invention relates to a tool or a device for installing and dismounting a cable or an electric wire, and in particular relates to a charged disconnecting wire lead clamp device which has the structural key points that the device comprises a first fixture body and a second fixture body, wherein the first fixture body has a reversed 'T'-shaped structure, and a through hole is arranged above the first fixture body; the outer side wall of the through hole is provided with a screw hole communicated with the through hole; a bolt is screwed into the screw hole from outside to inside, and the lower bottom of the screw hole is provided with a semi-circular arc-shaped groove; the second fixture body is provided with a semi-circular arc-shaped groove corresponding to the semi-circular arc-shaped groove arranged on the first fixture body; after the two semi-circular arc-shaped grooves are combined with each other, a circular hole can be formed; one shoulder side of the first fixture body and one should side of the second fixture body are respectively provided with a hinge joint component, and the other shoulder sides of the first fixture body and the second fixture body are respectively provided with a fastener; and the first fixture body is connected with the second fixture body by the fasteners. The charged disconnecting wire lead clamp device has the advantages that the working time of an operator in the electric field can be shortened, so that the safety of the operator can be guaranteed, and the working efficiency can be improved; and the lead clamp device is simple in structure, convenient to operate, firm in connection and good in practical effect. A copper wire rope can be simply and conveniently adjusted by the charged disconnecting wire lead clamp device.

Description

technical field [0001] The invention relates to a tool or equipment for installing and dismounting a cable or an electric wire, in particular to a wire clamp device for disconnecting a live wire. Background technique [0002] During the operation of the transmission line, due to the line infrastructure, defect treatment, etc., it is necessary to untie or connect the lead wire of a certain line connection point. When the line cannot be powered off to handle the above operations, only live work can be used to disconnect or connect. Connect the wires. The disconnection of the lead wire with power can only be carried out on the no-load line. At this time, the diversion rope must be used, and the no-load line has capacitive current, so arc suppression measures must be taken during the disconnection process. At present, the arc-suppression rope is used as a diversion and arc-extinguishing tool. The arc-suppression rope itself has no arc-suppression ability. It uses the artificial...
