Description
Technical field
The present invention relates to installation and removal instrument or the equipment, particularly a kind of charged disconnecting wire lead clamp device of a kind of cable or electric wire.
Background technology
In transmission line running, because the situations such as circuit capital construction, defect processing need to untie or connection work certain section of connection point lead-in wire, when circuit cannot have a power failure the above-mentioned operation of process, live line working method can only be adopted disconnect or overlap wire.Charged disconnecting lead-in wire can only carry out on nonloaded line, now must adopt water conservancy diversion rope, and nonloaded line has capacitance current, must take extinguishing arc measure in disconnecting process.At present, the instrument as water conservancy diversion and extinguishing arc is extinguishing arc rope, and extinguishing arc rope itself, without extinguishing arc ability, is utilize artificial opening speed to extend electric arc, reaches the object of self-gravitation.Extinguishing arc rope adopts the end of silk insulating cord or polyamide fibre insulating cord work out one section of copper rope and make.Need copper rope to tie up during live line working on the lead-in wire connecting wire, copper rope is connected with wire again and conducting simultaneously, and now copper rope is equal to the channelizing line of interim transition.
Due in charged disconnecting conductor leading process, copper rope is the channelizing line simultaneously connecting conductor leading, and in order to ensure completing smoothly of live line working, whether this copper rope colligation is firm on lead-in wire is vital.
In order to by this section of copper rope lashing lead-in wire on, and the length of serving as channelizing line meets safety work requirement, avoid occurring in extinguishing arc process that electric arc can not extinguish or colligation goes between the accident come off, need to carry out specification to lead-in wire technology for binding: first copper rope colligation on lead-in wire can not be less than 5 buttons, starting button is 8 word buttons, is and then along button, left-hand thread racking seizing.This technology for binding is comparatively loaded down with trivial details, needs the time long, and operating efficiency is low, and if in the electric field operating time longer, hand to grab copper rope not firm, all can there is serious accident.
Summary of the invention
The object of the invention is to provide a kind of simple to operate according to the deficiencies in the prior art part, the activity duration is short, and fail safe is high, and improves the charged disconnecting wire lead clamp device of operating efficiency.
The object of the invention is to be realized by following approach:
Charged disconnecting wire lead clamp device, its structural feature is, include the first clamp body and the second clamp body, first clamp body is inverse-T-shaped structure, top has a through hole, the lateral wall of this through hole is provided with the screw be communicated with this through hole, screws in bolt from outside to inside in screw, lower bottom part is semicircular arc groove; Second clamp body have the half-arc groove corresponding with the half-arc groove on the first clamp body, after the two merges, form a circular port, a shoulder side of the first clamp body and the second clamp body is articulated element, opposite side shoulder is provided with the securing member of connection first clamp body and the second clamp body.
Through hole on first clamp body is for placing copper rope, and the first clamp body and the second clamp body are combined the circular port of formation for connecting lead wire.Concrete operation method is: by copper rope through the through hole on the first clamp body, screw on bolt to precession in through hole, locking is to fix copper rope, unclamp the securing member on connection first clamp body and the second clamp body, open wire clamp, lead placement in the half-arc groove of the first clamp body or the second clamp body, then by two clamp bodies altogether, first-class securing member, completes connection.
Like this, only line clamping device as above need be adopted just can to realize the connection of copper rope and lead-in wire, wire clamp is gold utensil conductor, can realize conducting of copper rope and lead-in wire.This wire clamp adopts one to wear a folder structure, copper rope can just be arranged on wire clamp in advance before equal potential working personnel do not enter electric field, be connected to after entering electric field on lead-in wire, so just shorten operating personnel's operating time in the electric field, ensure that the safety of personnel, improve operating efficiency, line clamping device structure of the present invention is simple, easy to operate, it is firm to connect, and has very strong practical function.And, in use, in order to adapt to job requirements, when needing adjustment copper rope length, only need to unclamp bolt, simple to operate and do not affect the annexation of other parts.
The present invention can be specially further:
Also include a curved metal pad, it is arranged in the through hole on the first clamp body, is connected to bolt end.
In order to avoid the locking of bolt can damage copper rope to the extruding force that copper rope produces, therefore increase by a curved metal pad, along with the locking of bolt can be distributed on arc metal plate the extruding force that copper rope produces, reduce the damage to copper rope.
Also include a junction, it is arranged in the first clamp body top ends.
This connecting portion is for connecting insulation stay cord, and such operating personnel just can operate insulation stay cord at any time, or operates this wire clamp by insulation stay cord, adjustment wire clamp position etc.
Above-mentioned connecting portion is a kind of annulus.Be convenient to like this by the colligation of insulation stay cord on this annulus, not only firm but also simple.
In sum, the invention provides a kind of charged disconnecting wire lead clamp device, adopt one to wear a folder structure, copper rope can just be arranged on wire clamp in advance before equal potential working personnel do not enter electric field, be connected to after entering electric field on lead-in wire, so just shorten operating personnel's operating time in the electric field, ensure that the safety of personnel, improve operating efficiency, line clamping device structure of the present invention is simple, easy to operate, it is firm to connect, and has very strong practical function.And, in use, in order to adapt to job requirements, when needing adjustment copper rope length, only need to unclamp bolt, simple to operate and do not affect the annexation of other parts.
