Description
Technical field
The utility model relates to a kind of drainage thread, particularly the interim shunt line of a kind of hot line maintenance.
Background technology
At present, transmission line drainage thread is that connection power line tension shaft tower is horizontal carries both sides wire, makes it connect and keep certain safe distance with shaft tower, ensures the wire of the normal transmission of electric energy of circuit.Along with the development of China's economic society, the sharp increase of power consumption load, usually causes numerous transmission line at full capacity or overload operation, the heating of transmission line drainage thread often occurs, finally causes drainage thread to burn, blow.
When carrying out hotline maintenance to power line tension shaft tower drainage thread and removing, the electric current that an interim shunt line passes through to shunt former transmission line drainage thread must be adopted, thus ensure in the process of electric transmission line hot-line maintenance drainage thread, strain rod tower both sides wire still reliably connects, avoid the interruption causing because carrying out upkeep operation to drainage thread powering, and run in running at transmission line, when run into drainage thread due to bolted not in place, put forth effort uneven, wire clamp does not mate with wire, the reason such as aging causes drainage thread to generate heat, burn, damage, disconnected stock, throw stock, the problems such as annex corrosion, power line tension drainage thread will be caused to break as carried out maintenance to it not in time and because of persistent fever, drainage thread resistance is increased sharply, temperature raises, thus cause huge energy loss, affect the safe operation of transmission line.
But the wire clamp product heaviness of existing fixing shunt line, operating difficulties, can only equipotential operation be carried out, fail safe and reliability poor, the hotline maintenance drainage thread job requirements of 110-220 KV transmission line cannot be met, so existing shunt line is still perfect not.
Summary of the invention
The purpose of this utility model is: provide that the fail safe of a kind of structure simple, practical and reliable property is high, quality is light, portable, easy to operate, both can earth potential operation also can equipotential install, realize adding shunt line outside circuit body drainage thread by wire clamp, in live line working process, ensure reliability, the continuation of powering; The transformation of the force direction of wire clamp loosen preparation procedure is realized by mechanics means, make live line working personnel can carry out degree of tightness adjustment to wire clamp more easily in work high above the ground, by the process of the complete dual problem drainage thread of the mode of live line working, whole process without the need to having a power failure, simple to operate and safe and reliable, while guarantee circuit normally runs, improves power supply reliability, remove again the interim shunt line of a kind of hot line maintenance of line defct, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: the interim shunt line of a kind of hot line maintenance, comprise "T"-shaped wire clamp, wire clamp is provided with two interconnective vertical gears and transverse gear, vertical gear is connected with handle by connecting axle, the portable cord clamping bar that can move up and down is provided with on wire clamp and at the middle part of transverse gear, the end of portable cord clamping bar is provided with wire clamp hook, wire clamp is provided with the clip slot that can match with wire clamp hook, wire clamp is provided with the inside groove that wire clamp hook gib head can be allowed to insert, wire clamp is provided with moving hole, shunt line is provided with in moving hole.
Portable cord clamping bar is provided with the external screw thread that can match with transverse gear internal thread.
Owing to have employed technique scheme, the utility model utilizes two wire clamps to be fixedly connected on by shunt line on the operating main traverse line in strain rod tower cross-arm both sides, and its radian, size are consistent with former shaft tower drainage thread, are shifted by the electric current that former drainage thread flows through; Compared with prior art, it is simple that the utility model not only has structure, and design ingenious, by the process of the complete dual problem drainage thread of the mode of live line working, whole process without the need to having a power failure, simple to operate and safe and reliable, while guarantee circuit normally runs, improves power supply reliability, remove line defct again; Wire clamp adopts high-strength aluminum alloy to be made, and no matter the connection of device and former wire is the conductivity aspect of intensity or contact-making surface, and the advantage such as all increase significantly.
