The utility model relates to a rationally, easy operation, solved the unsafe problem of ubiquitous switch class return circuit resistance test data for a long time, avoided the emergence of burning out contact springing, validity and security that the pilot project is develoied improve, still useful to other pilot projects such as ac voltage withstand test measurements, mechanical characteristic test in, provide the maintenance logistics for experimental analysis of the data and lean manage, can widely popularize the use in electric power engineering.
Description
Technical field
This utility model belongs to electric power safety field, relates to safety inspection aid, especially a kind of Switch equipment loop resistance subtest folder.
Background technology
In transformer station in the electrical test of primary equipment, the electrical test of the Switch equipment such as chopper, disconnecting switch is particularly significant, and many pilot projects there is also problem demanding prompt solution.As a example by loop resistance measurement, present chopper producer type kind is various, finds that some chopper, due to reasons such as fracture textures, the phenomenon that contact activity cannot be fixed occurs at the scene in actual measurement.The most common chopper Mume flower contact, as it is shown in figure 1, in recess 4 in chopper Mume flower contact 1, be provided with movable contact 2 outside recess, the outer concentric at movable contact is set with spring 3.It is only optimal test point need to clip to ramp the recess of Mume flower contact when loop resistance is tested in.And contact connecting lever side is often closed by insulant, when causing loop resistance measurement, test connection folder can only be clipped on movable contact, the optimal test point of the required test of chopper cannot be clipped to, the data so tested out are bigger than normal, and the numerical value measured is the most different every time, error is bigger, it is impossible to objectively respond the exact value of loop resistance；If it addition, clip to, on the spring of Mume flower contact, easily burn when logical super-high-current or damage touch spring by the electric current of loop resistance measurement instrument, affect test accuracy and work efficiency, tester may be caused security threat simultaneously.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of easy to carry, simple to operate, test precise and high efficiency and safety high Switch equipment loop resistance subtest folder.
This utility model solves above-mentioned technical problem is that and takes techniques below scheme to realize:
A kind of Switch equipment loop resistance subtest folder, described test clip includes that upper clamp and lower clamp, described upper clamp and lower clamp are the arc of specular, and the anterior side specular respectively of described upper clamp and lower clamp offers groove；The middle part of described upper clamp and lower clamp is flexibly connected by screw；The rear portion of described upper clamp and lower clamp is coaxially coated with pin, and the lower end of described pin is fixed with described lower clamp rear outside by nut；It is spaced in the upper end of described pin and described upper clamp rear portion and is coaxially arranged with tension device, be coaxially arranged with between described tension device with described upper clamp rear portion and be connected metal handle.
And, described test clip is the copper silver plated metals folder of long 18cm, and a diameter of 7mm of described pin, the width of rebate of described groove is 30mm.
Advantage of the present utility model and having the beneficial effect that
1, test clip simple in construction of the present utility model, solid firm, pin is regulated by tension device, thus control upper clamp and lower clamp, in making the optimal test point being fastened on contact of breaker that the front end of upper clamp and lower clamp consolidates, it is easy to sandwiching of test connection folder, keeps the stability in test process, improve accuracy and the safety of operator of test.
2, test clip of the present utility model offers groove at upper clamp and side, lower clamp front portion specular respectively, can arrange groove width according to the size of different contact of breaker, it is adaptable to the contact of breaker of different model, increase range.
3, test clip volume of the present utility model is little, and light weight is convenient for carrying, simple to operate controlled, saves man power and material's cost, improves experiment work efficiency.
4, this utility model is reasonable in design, simple to operate, designs a kind of Switch equipment test special testing tool pointedly, this instrument can directly, the optimal test point of contact switch contact well, especially breaker loop resistor is measured especially suitable.The most important thing is to solve the Switch loop resistance test inaccurate problem of data the most generally existed, avoid the generation burning touch spring phenomenon, improve effectiveness and safety that pilot project is carried out, can also use in other pilot projects such as ac voltage withstanding measurement, testing mechanical characteristic, analysis and lean management for test data provide technology and ensure, can vigorously promote the use in power engineering.

Fig. 2 is front view of the present utility model；
Fig. 3 is the right view of Fig. 2.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following example are illustrative, is not determinate, it is impossible to limits protection domain of the present utility model with this.
A kind of Switch equipment loop resistance subtest folder, described test clip is the copper silver plated metals folder of long 18cm, as shown in Figure 2, including upper clamp 8 and lower clamp 11, described upper clamp and lower clamp are the arc of specular, and the anterior side specular respectively of described upper clamp and lower clamp offers the groove 10 that width of rebate is 30mm；The middle part specular of described upper clamp and lower clamp offers screw hole 9, and screw is flexibly connected upper clamp and lower clamp by described screw hole；The rear portion of described upper clamp and lower clamp is coaxially coated with the pin 7 of a diameter of 7mm, and the lower end of described pin is fixed with described lower clamp rear outside by nut 12；It is spaced in the upper end of described pin and described upper clamp rear portion and is coaxially arranged with tension device 6, be coaxially arranged with between described tension device with described upper clamp rear portion and be connected metal handle 5.
Operation principle of the present utility model: before test operation, testing crew is ready by test instrument, instrument, electric current line etc.；Test clip of the present utility model is extend into the recess 4 of chopper Mume flower contact, till can not going deep into again；Slowly tighten tension device, the tightliest cause along with tension device upper clamp rear portion stress to move down so that (as shown in Figure 3) is opened in the upper clamp of test clip and lower clamp front portion, until with the recess inwall good contact of chopper Mume flower contact；Now the groove of upper clamp and side, lower clamp front portion is fastened on the inwall of movable contact just so that test clip is the most loosening, now tension device also be connected metal handle compacting firmly；By electric current line one end joint test instrument of circuit resistance tester, the other end is clipped in the connection metal handle of this instrument；After guaranteeing that all wiring are the most complete, i.e. can start the measurement of loop resistance.
