Abstract
The utility model discloses a tool for a single hanging and twin suspension insulator string capable of solving the problem of earth potential electrified transmission line replacement. The tool comprises two support arms; an obtuse angle is formed between the two support arms; and a mounting hole is formed at the outer end of one support arm, and a clamping groove with an opening is formed at the outer end of the other support arm. The two support arms are jointlessly formed and made of high-strength aluminium alloy. The utility model can perform operation to the overhaul and replacement of a single hanging and twin suspension insulator, avoid the economic loss caused by power failure or the problem of low equipment operation level caused by the short-time live working during replacement, and can solve the problems of air clearance of short-circuit between the tool and the insulator string, and labor intensity of operation personnel, thereby greatly reducing power failure frequency and power failure time of the transmission line, reducing non-planning outage rate of the transmission line, and improving the power supply reliability of the transmission line. Moreover, the utility model has the advantages of simple structure, safety, practicality, and low cost.
Description
Technical field
The utility model relates to a kind of electric power facility maintenance tool, relates in particular to a kind of instrument that earth potential live replacing transmission line list is hung the duplex suspension insulator that solves.
Background technology
At present, each electric company mostly adopts the compound mode of bent plate card and thread gripping-board that " single duplex of hanging " insulator string is carried out hotline maintenance, to reduce the transmission line frequency of power cut.In the case, at first because the screw mandrel length of bent plate card has 250mm, short circuit the air gap of insulator string, reduced insulativity; Secondly operating personnel wants the whole body both hands operation of popping one's head in of leaning to one side of lying prone on the lead cross-arm downwards, and not only labour intensity is very big, and the operating personnel has certain unsafe factor.
Summary of the invention
The purpose of this utility model is: a kind of instrument that solves earth potential live replacing transmission line list extension duplex suspension insulator that a kind of new structure above-mentioned defective of solved prior art simple, safe and practical, with low cost is provided.
The purpose of this utility model realizes by following scheme: be made of two support arms, two arm rooms form the obtuse angle, and wherein a support arm outer end is provided with installing hole, and another support arm outer end is provided with the opening draw-in groove.
Two support arms described in the utility model are one-body molded.
The utility model is made by high strength alumin ium alloy.
The utility model can be changed at single maintenance of hanging the duplex insulator carry out operation, avoids economic loss brought by power failure or problem that the operation level of changing the equipment that influences of not having a power failure in short-term reduces.Possess following characteristics: 1, can be convenient, fast, be installed on the transmission line L1040-L2040 type yoke plate effectively.2, can carry the load of lead porcelain vase string carrying, and be not less than 30KN.3, can be used with other instruments effectively, the electrician all can conveniently use on ground electrician and the bar.4, can solve the problem of instrument short circuit insulator string air gap and operating personnel's labour intensity, and significantly reduce the frequency of power cut and the interruption duration of transmission line, reduce the unplanned outage rate of transmission line, improve the power supply reliability of transmission line.5, simple in structure, safe and practical, with low cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is made of two support arms 1,2 of being made by high strength alumin ium alloy, and 1,2 of two support arms form the obtuse angle, and support arm 1 outer end is provided with opening draw-in groove 3, and support arm 2 outer ends are provided with and install and fix hole 4.
By installing and fixing hole 4 the utility model is fixed on three yoke plates of transmission line cross-arm below during use, cooperates pulley, insulation ropes that single duplex insulator of hanging is carried out various operations by opening draw-in groove 3.
