Abstract

The invention discloses a wire clamp for being connected with a live wire during live working. The wire clamp is characterized by comprising a fixing end (1), a fixing hook (1-1) and a fixing end seat (1-2) are connected with each other to form the fixing end (1), the upper portion of the fixing end seat (1-2) is movably connected with a wire end pressure plate (3) by a fixing bolt (2), the lower portion of the fixing end seat (1-2) is connected with a fastening screw (6) in a threaded manner, one end of the fastening screw (6) is connected with a fastening end (5), and the other end of the fastening screw (6) is connected with a fastening bolt (4). The wire clamp has the advantages that the wire clamp is simple in structure and attractive in appearance, is safe and reliable, and is applicable to being connected with live wires of different types of distribution overhead lines in a live manner, connecting leads of the overhead lines can naturally droop in an overhung chain manner, the fastening bolt (4) not only can be operated just like a common movable wrench or a socket wrench, but also can be operated by the aid of an insulating operating rod with an end, the live working efficiency is improved, and the live working safety is guaranteed.

Description

A kind of wire clamp of starting to exchange fire for live line working
Technical field:
The present invention relates to a kind of wire clamp, relate in particular to a kind of for a kind of wire clamp of starting to exchange fire for live line working of distribution overhead line.
Background technology:
the distribution overhead line live line working can not only avoid the user to have a power failure, and the activity duration is more flexible, along with social economy's improving constantly the power supply reliability requirement, distribution line live working project and scope enlarge year by year, but in distribution overhead line live line working work, the operating personnel is when charged installation branch line, originally be used for the wire connecting clip of power failure operation when fixing end, inapplicable insulating bar live line working mode not only, and different with two kinds of operating types of live line working owing to having a power failure, former wire connecting clip is in direct live line working process, fluctuation of service, often come off, and after former wire connecting clip installs, also need to adjust branch line tip bend shape, increased the insecurity of live line working.Occur in order to change analogue, be badly in need of a kind of direct live line working use of starting to exchange fire that both had been suitable for of development, be fit to again the wire clamp of insulating bar band electro ultrafiltration, to improve power distribution live-wire scope and efficient, guarantee equipment installment quality, guarantee the fail safe of distribution overhead line live line working.
Summary of the invention:
The deficiency that the object of the invention is to overcome above-mentioned prior art provides a kind of simple in structure, safe and reliable, flexible adjustment, install firm, applied widely, improve live line working efficient, guarantee the wire clamp that live line working is started to exchange fire that is used for of live-working safety.
Purpose of the present invention can reach by following measure: a kind of wire clamp of starting to exchange fire for live line working, it is characterized in that it comprises fixedly termination, fixedly the termination is connected and composed by stay hook and stiff end headstock, the top of stiff end headstock is flexibly connected the end of a thread pressing plate by set bolt, the lower thread of stiff end headstock connects fastening screw, one end of fastening screw connects fastening termination, and the other end connects fastening bolt.
The present invention can produce following good effect compared with the prior art: the present invention can realize the insulating bar operation with belt end, the also common box spanner operation of available use, and the branch line lead ends does not need to adjust curved shape again, only need to be connected with the stiff end hook bolt by the end of a thread pressing plate to be fixed, make it to realize that the overhead transmission line connecting lead wire chain that becomes to dangle naturally droops, reduce
The live line working time, improve live line working efficient, guarantee live-working safety, the convenient and installation quality that assurance equipment is installed.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of wire clamp (referring to Fig. 1) of starting to exchange fire for live line working, made by copper material, it comprises fixedly termination 1, fixedly termination 1 is connected and composed by stay hook 1-1 and stiff end headstock 1-2, the top of stiff end headstock 1-2 is flexibly connected the end of a thread pressing plate 3 by set bolt 2, the lower thread of stiff end headstock 1-2 connects fastening screw 6, and an end of fastening screw 6 connects fastening termination 5, and the other end connects fastening bolt 4.
During use, lead ends is pressed abd fixed between the end of a thread pressing plate 3 and stiff end headstock 1-2 by set bolt 2, by insulating bar or employing direct maintenance, the fixing stay hook 1-1 of termination 1 is hooked on built on stilts alive circuit, and drive fastening screws 6 by rotation fastening bolt 4 fastening termination 5 and stay hook 1-1 are fixed on built on stilts alive circuit, realize starting to exchange fire, the overhead transmission line connecting lead wire chain that becomes to dangle is naturally drooped, appearance looks elegant improves operating efficiency and fail safe.Fastening bolt 4 is available common adjustable wrench or box spanner operation both, also can use the insulating bar operation of belt end.
