Abstract
The utility model relates to a transformer reactance method winding deformation testing short circuit termination, its major technical features is: including terminal, insertion rod, nut and rubber sleeve, insertion rod install in terminal upper end, have the middle part screw thread and be connected with the nut in the middle part system of terminal, the rubber sleeve suit in the lower part of terminal. The utility model relates to a rationally, link together terminal and insertion rod, has realized quick, reliable, the convenient short circuit wiring function of transformer reactance method winding deformation testing middle and low voltage side having made things convenient for the wiring work of staff in carrying out reactance method winding deformation testing, improved test efficiency, guaranteed the validity of field test testing result, have the structure concisely, advantages such as safe and reliable, simple operation.
Description
Technical field
The utility model belongs to transformer test technical field, especially a kind of transformer reactance method winding deformation test shortening contact device.
Background technology
Transformer is after suffering short-circuit impact, and entirety or local deformation may occur winding, and anti-short circuit capability is significantly declined, and being detected by winding deformation can Timeliness coverage winding defect, has vital role to prevention transformer short-circuit impact failure.Can intuitively quantize because winding deformation reactance method has Testing index, tested person environmental impact is less, the advantage that testing result reproducibility is strong, and on-the-spot normal the method that adopts is diagnosed deformation of transformer winding situation.When adopting reactance method to carry out deformation of transformer winding detection, need centering, low-pressure side sleeve pipe carries out short-circuit operation respectively, the mode that on-the-spot more employing bare copper wire is wound around, the not only test setup time of at substantial, also there is the phenomenons such as short circuit is unreliable, affect the validity of test result, greatly reduce test efficiency and reliability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple and clear, safe and reliable, the transformer reactance method winding deformation of simple operation test shortening contact device.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of transformer reactance method winding deformation test shortening contact device, comprise binding post, shank, nut and rubber sleeve, described shank is arranged on binding post upper end, and be shaped with middle part screw thread at the middle part of binding post and be connected with nut, described rubber sleeve is sleeved on the bottom of binding post.
Described binding post top is shaped with top screw thread, binding post and shank is installed together by top screw thread.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, binding post and shank are linked together, achieve transformer reactance method winding deformation test mesolow side quick, reliably, shortening contact function easily, facilitate staff and carry out the wiring work in the test of reactance method winding deformation, improve test efficiency, ensure that the validity of site test testing result, there is the advantages such as structure is simple and clear, safe and reliable, simple operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of transformer reactance method winding deformation test shortening contact device, as shown in Figure 1, comprise binding post 4, shank 1, nut 2 and rubber sleeve 3, be shaped with the top screw thread 6 be connected with shank on binding post top, binding post and shank can be installed together by top screw thread; Be shaped with middle part screw thread 5 at the middle part of binding post and be connected with nut; Described rubber sleeve is sleeved on the bottom of binding post, for mounting and dismounting this shortening contact device, with the fixing reliable and simple operation of assurance device.The utility model realizes in transformer by two kinds of modes, the shortening contact function of low-tension bushing, a kind of mode is realized by shank, shank is connected with binding post, and be linked in bushing shell for transformer terminal block 7 by inserting mode, thus realizing short-circuit function, its maximum caliber meeting bushing shell for transformer terminal block is 20mm; Another kind of mode is as the bore of bushing shell for transformer terminal block excessive (during more than 20mm), shank and binding post is removed, and the mode of being fixed by nut and screw thread, realizes short-circuit function.
The utility model in use, carries out installation and removal in two kinds of situation:
1, when transformer mesolow sleeve pipe yoke plate screw bore is less than 20mm,
(1) shank and binding post are threaded togather by top;
(2) shank is torn open into bushing shell for transformer yoke plate, repeatedly compress from rubber sleeve;
(3), after test, extract by fluctuating.
2, when transformer mesolow sleeve pipe yoke plate screw bore is greater than 20mm,
(1) shank on binding post is removed;
(2) binding post is inserted bushing shell for transformer yoke plate, utilize nut and middle part screw thread to be fixed;
(3), after test, remove nut, extract binding post.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
Claims (2)
1. a transformer reactance method winding deformation test shortening contact device, it is characterized in that: comprise binding post, shank, nut and rubber sleeve, described shank is arranged on binding post upper end, be shaped with middle part screw thread at the middle part of binding post and be connected with nut, described rubber sleeve is sleeved on the bottom of binding post.
2. transformer reactance method winding deformation test shortening contact device according to claim 1, is characterized in that: described binding post top is shaped with top screw thread, binding post and shank is installed together by top screw thread.
