Description
Technical field
The utility model relates to the installation and removal instrument or the equipment of a kind of cable or electric wire, particularly a kind of charged disconnecting conductor leading line clamping device.
Background technology
In the transmission line running, because situation such as circuit capital construction, defect processing need untie or connection work certain section circuit tie point lead-in wire, can't have a power failure when handling above-mentioned operation at circuit, can only adopt the live line working method to break off or overlap lead.Charged disconnecting lead-in wire can only carry out on nonloaded line, and must adopt the water conservancy diversion rope this moment, and nonloaded line has capacitance current, in the disconnecting process, must take the extinguishing arc measure.At present, be the extinguishing arc rope as the instrument of water conservancy diversion and extinguishing arc, the no extinguishing arc ability of extinguishing arc rope itself is to utilize artificial opening speed extension electric arc, reaches the purpose of self-gravitation.Extinguishing arc rope is to adopt end one section copper rope of establishment of silk insulation rope or polyamide fibre insulation rope and process.Need copper rope be tied up on the lead-in wire that connects lead during live line working, copper rope is connected with lead again and conducting simultaneously, and this moment, copper rope was equal to the channelizing line of interim transition.
Because in charged disconnecting conductor leading process, copper rope is the channelizing line that connects conductor leading simultaneously, and in order to guarantee the smooth completion of live line working, whether this copper rope colligation is firm on lead-in wire is vital.
For with the firm colligation of this section copper rope the lead-in wire on; And the length of serving as channelizing line meets the safety work requirement; Avoid in the extinguishing arc process, occurring the accident that electric arc can not extinguish or the colligation lead-in wire comes off; Need carry out standard to the lead-in wire technology for binding: at first copper rope colligation on lead-in wire can not be less than 5 buttons, and the starting button is 8 word buttons, and then is 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 the operating time is long, to hold copper rope in hand not firm in electric field, all serious accident can appear.
The utility model content
The purpose of the utility model is to provide a kind of simple to operate according to the weak point of prior art, and the activity duration is short, and is safe, and improves the charged disconnecting conductor leading line clamping device of operating efficiency.
The purpose of the utility model realizes through following approach:
Charged disconnecting conductor leading line clamping device; Its structural feature is, includes first clamp body and second clamp body, and first clamp body is inverse-T-shaped structure; The top has a through hole; The lateral wall of this through hole is provided with the screw that is communicated with this through hole, screws in bolt in the screw from outside to inside, and lower bottom part is the semicircular arc groove; Have on second clamp body with first clamp body on the corresponding half-arc groove of half-arc groove; After the two merges; Form a circular port, a shoulder side of first clamp body and second clamp body is an articulated element, on the opposite side shoulder securing member that connects first clamp body and second clamp body is installed.
Through hole on first clamp body is used to place copper rope, and first clamp body is used to be connected lead-in wire with the circular port that second clamp body lumps together formation.Concrete operation method is: copper rope is passed the through hole on first clamp body, and the bolt precession in through hole of screwing on, locking is to fix copper rope; Unclamp the securing member that connects on first clamp body and second clamp body; Open wire clamp, lead placement in the half-arc groove of first clamp body or second clamp body, then altogether with two clamp bodies; First-class securing member is accomplished connection.
Like this, only need to adopt aforesaid line clamping device just can realize being connected of copper rope and lead-in wire, wire clamp is the gold utensil conductor, can realize conducting of copper rope and lead-in wire.This wire clamp adopts one to wear a folder structure, and copper rope can just not be installed on the wire clamp before the equal potential working personnel get into electric field in advance, is connected on the lead-in wire behind the entering electric field; So just shorten the operating time of operating personnel in electric field, guaranteed personnel's safety, improved operating efficiency; The said line clamping device of the utility model is simple in structure; 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 unclamp bolt and get final product, simple to operate and do not influence the annexation of other parts.
The utility model can further be specially:
Also include a curved metal pad, it is installed in the through hole on first clamp body, is connected the bolt end.
Can damage copper rope for fear of the locking of bolt to the extruding force that copper rope produces, therefore increase by a curved metal pad,, reduce damage copper rope along with the locking of bolt can be distributed on the arc metal plate the extruding force that copper rope produces.
Also include a junction, it is installed on the first clamp body top ends.
This connecting portion is used for connecting the insulation stay cord, and the operating personnel just can operate the insulation stay cord at any time like this, perhaps through this wire clamp of insulation stay cord operation, adjustment wire clamp position or the like.
Above-mentioned connecting portion is a kind of annulus.Be convenient to like this colligation of insulation stay cord on this annulus, not only firm but also simple.
In sum, the utility model provides a kind of charged disconnecting conductor leading line clamping device, adopts one to wear a folder structure; Copper rope can just not be installed on the wire clamp before the equal potential working personnel get into electric field in advance, is connected on the lead-in wire behind the entering electric field, has so just shortened the operating time of operating personnel in electric field; Guaranteed personnel's safety, improved operating efficiency, the said line clamping device of the utility model is simple in structure; 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 unclamp bolt and get final product, simple to operate and do not influence the annexation of other parts.
