Description
Technical field
The utility model relates to a kind of electrical test and uses scalable coupling arrangement, is used for electrical test and connects.
Background technology
When carrying out electrical test; Many pilot projects require each terminal of equipment is carried out short circuit and short circuit ground connection; Like dielectric loss test, the industrial frequency AC withstand voltage test of the insulation resistance of transformer and absorption ratio test, winding and bushing, the insulation resistance test of short-circuiting device fracture etc. to shell and ground.
The common mode of carrying out the short circuit wiring has following several kinds at present:
1. fuse or soldering silk carry out short circuit, and its advantage is the intercepting easily of soldering silk softness, can be at the short-and-medium terminal of taking over the meaning spacing of any pilot project, and the size of terminal is restriction not, better appearance after the completion wiring.Its shortcoming is that recycling rate of waterused is low, belongs to disposable wiring, and fuse and soldering silk can not continue test through breaking after the bending repeatedly several times; Fuse after little spacing terminal test is because blocked, and length is too short, can not be used on the big spacing terminal again; Do not have insulating sheath, when carrying out high-voltage test, be prone to produce corona, influence test findings.
2. carry out short circuit through the multiply bare copper wire, advantage is relative fuse and durable, the tension of soldering silk, can reuse; Can adapt to the connection of different spacing terminal, shortcoming be can not the control linkage line length, can only shorten unnecessary lead through between several terminals, repeating to connect when connecting the short spacing terminal; Copper wire has certain elasticity, repeatedly uses the back copper cash to occur the phenomenon of tiing a knot easily, and is difficult to untie, and influence continues to use and test the arrangement of front and back; Do not have insulating sheath, when carrying out high-voltage test, be prone to produce corona, influence test findings.
3. make special-purpose short-circuit line, advantage is to use pliers to replace bare conductor winding, hook mode to carry out wiring, and is more quick and easy and reliable; Integrated design, solid and reliable, arrangement is convenient.Shortcoming is can only be used on the special equipment and project.As can only be used for the 10kV transformer, if be used for the voltage levels transformer, then the length of line is not enough.If make the longer wiring of length, when being used for the 10kV transformer, can make the long lead of arrangement become a trouble.
4. use combination line to carry out short circuit, all be equipped with different in sizely in many equipment, have the combination line of unified plug, can connect, extend, plug combinations such as alligator forceps and connection terminal to these lines in fast and flexible ground, it is versatile and flexible that advantage is to use; Durable, solid, really accomplished and can reuse; Can be through alligator forceps that is equipped with different model or the needs that connection terminal adapts to various short-circuiting terminal.Shortcoming is to select the line of appropriate length to connect according to the size of distance between the short-circuiting terminal, and it is very big to assort the amount that is equipped with, and also takes time to the arrangement of the line of all lengths in the test front and back very much.
In real work, because of needs become very loaded down with trivial details repeatedly, disconnecting in the line process repeatedly, not only damage shorting stub easily, and line is different in size, wrapping phenomena often takes place each other, and putting in order wastes time and energy.How to make this process more fast, standard, more clear, the attractive in appearance inspection of conveniently carrying out wiring of wiring becomes more urgent.
Summary of the invention
The purpose of the utility model is for improving existing electrical cable, provide a kind of simple in structure, can be fast, standard, clear a kind of electrical test attractive in appearance use scalable coupling arrangement.
Scalable coupling arrangement is used in a kind of electrical test, comprises line stretcher box, lead, bullet rod plug, and the line stretcher box adopts two backguy double track line stretcher boxes, has two-way stretch, two-way contraction, dual swing-around trajectory function; The pin tail of bullet rod plug can connect utmost point interfix, realizes being connected; Lead is the flat wire with electrical specification, is convenient to be placed in the line stretcher box, to carry a certain size electric current; Lead in the line stretcher box requires to place according to reality and can bear the lead of corresponding size of current; Lead is placed in the line stretcher box; Lead two the end of a thread are exposed at line stretcher box outside respectively and connect two bullet rod plugs; Carry out the short circuit connection when being convenient to carry out electrical test and be connected many p-wires with same contact; Because bullet rod plug has end to end characteristic, can be combined into the electrical cable of different size of current, different length, from the line stretcher box, pulls out the lead of suitable length according to the test needs.Expand the length of lead through being connected in series, being connected in parallel enlarges the conductive capability of lead, and changes not in specie jointing clamp, terminal and fish tail folder through bullet rod plug.
The advantage of the utility model is, improves the efficient of short circuit wiring, the damage that reduces shorting stub and the preliminary work before and after the short form test, and easy-to-connect is quick, durable, the wiring neat appearance; With convenient arrangement later,, reduce connecting line quantity according to terminal pitch adjustment length; It is anticorona to have insulation course, and unified joint is arranged, and can make up each other; And can change not jointing clamp and terminal in specie, and having better practicability, the application scenario is extensive.
