Description
Technical field
This utility model belongs to reaying protection test and maintenance articles for use technical field, particularly relates to a kind of multitap electric current shorting stub.
Background technology
When reaying protection test, it is often necessary to electric current secondary loop line is carried out short circuit process, it is prevented that electric current secondary side open circuit causes unnecessary tripping operation, equipment fault and personal injury；When current loop overhauls, also tend to need electric current secondary loop line carries out short circuit process, to reach the effect of quick fault point.So it is very general that electric current secondary loop carries out short circuit application in substation equipment maintenance and repair and reaying protection test, it is of great importance again at secure context simultaneously.Related specifications according to substation equipment maintenance and repair, need to go out carry out at current wiring terminal to the short circuit of electric current secondary loop.At present, in the whole electric current secondary loop from current transformer to protective relaying device, have more use current wiring terminal, and these current wiring terminal patterns, model are all not quite similar.Plug-in, spring, fence type etc. can be divided into.Known electric current short-circuit tool, only can to the terminal short circuit of a kind of pattern and model, and one group of electric current of short circuit only.One group of electric current short circuit to different model terminal cannot be accomplished, also cannot accomplish many group electric current short circuits.
Summary of the invention
The purpose of this utility model is that invention one can be general between different model current terminal for some problems overcoming above-mentioned known electric current short-circuit tool to exist, and can increase the multitap electric current shorting stub of the group number of short circuit current.In order to achieve the above object, this utility model is achieved through the following technical solutions: a kind of multitap electric current shorting stub, it is made up of shorting stub body (referring to Fig. 1) and plug external member (referring to Fig. 2) two parts, described shorting stub body is separated 12 short circuit wires by a common contact, each short circuit wire tail is the public plug of diameter 4mm, short circuit wire core and public plug are fine copper material, with the soft sheath parcel of silica gel outside core, described plug external member is the external member plug that can conveniently be connected shorting stub body and terminal by the current wiring terminal of different model, external member plug totally 4 kinds, it is respectively as follows: external member A, external member B, external member C and suit D, its common trait is the jack that afterbody is diameter 4mm, the difference is that: external member A, head is the contact pin of diameter 2mm；External member B, head is the alligator clamp of opening 20mm；External member C, head is the U-shaped inserted sheet of opening 6mm；Suit D, head is the U-shaped inserted sheet of opening 10mm, and jack is fine copper material, and the soft sheath parcel of silica gel outside jack, various plug is fine copper material.
This utility model has 12(9) bar branch, can simultaneously to two groups of electric current short circuits.This utility model can also pass through to change the mode of plug external member, it is achieved that carries out electric current short circuit work on different model terminal.Plug external member can independent assortment use, to the one group of electric current short circuit using different model terminal.This utility model fundamentally solves currently used short-circuit tool cannot accomplish one group of electric current short circuit to different model terminal, also cannot accomplish the drawbacks organizing electric current short circuits more, makes electric current short circuit work convenient and efficient more.

Detailed description of the invention
As shown in the figure: a kind of multitap electric current shorting stub, it is made up of shorting stub body (referring to Fig. 1) and plug external member (referring to Fig. 2) two parts, it is characterized in that: described shorting stub body is separated 12 short circuit wires 1 by a common contact 3, each short circuit wire 1 afterbody is the public plug 2 of diameter 4mm, short circuit wire 1 core and public plug 2 are fine copper material, with the soft sheath parcel of silica gel outside core, described plug external member is the external member plug that can conveniently be connected shorting stub body and terminal by the current wiring terminal of different model, external member plug totally 4 kinds, it is respectively as follows: external member A, external member B, external member C and suit D, its common trait is the jack 4 that afterbody is diameter 4mm, the difference is that: external member A, head is the contact pin 5 of diameter 2mm；External member B, head is the alligator clamp 6 of opening 20mm；External member C, head is the U-shaped inserted sheet 7 of opening 6mm；Suit D, head is the U-shaped inserted sheet 8 of opening 10mm, and jack 4 is fine copper material, and the soft sheath parcel of silica gel outside jack 4, various plug is fine copper material.
During use, only need to selecting suitable plug external member according to the model of current terminal, the plug of shorting stub body inserts the jack (referring to Fig. 3) of plug external member afterbody, then head is connected with current terminal by the head of plug external member.If being suitable for the plug that current terminal plug is diameter 4mm, then can directly be connected with current terminal with public plug 2.
