Abstract
The utility model relates to a kind of 10kV wheelbarrow switch test plug, and its structure is, the different developmental tube A of internal diameter is connected with developmental tube B, and developmental tube A is provided with a gap, places and compress shell fragment in gap; The outside surface of developmental tube B is provided with insulating outer layer.The contact pin of secondary plug and test lead termination are perfectly plugged in together by the utility model.Solve variety of problems and unfavorable factor that current site work crocodile clip steps up contact pin generation.Improve security and the operating efficiency of site work.
Description
Technical field
The utility model relates to a kind of switch test plug, particularly relates to a kind of 10kV wheelbarrow switch test plug, belongs to electric power application.
Background technology
Switching characteristic test needs with switching characteristic tester, adds direct current operative power source to switch examination.Maintainer usually chooses corresponding test contact pin and tests on the secondary plug of wheelbarrow switch (being commonly called as " plait "), and clamps contact pin with test line end crocodile clip, but this process being not easy.On secondary plug, contact pin is intensive, and crocodile clip is comparatively large, does not slightly notice that the metallic member of crocodile clip will touch other contact pins, causes experiment power supply short circuit, loop open circuit, make test failure; And contact pin smooth surface on secondary plug, the surface of contact between crocodile clip and contact pin is " point " and the contacting of " face ", and clamping force is less, usually causes crocodile clip to loosen, comes off, cannot firm grip.If send the hand-held crocodile clip of personnel, though above-mentioned two kinds of drawbacks can be solved, but the trial voltage exported can be caused to wound the maintainer holding crocodile clip.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of 10kV wheelbarrow switch test plug, solves in prior art the problem tested contact pin and not easily contact with test line end.
The technical solution of the utility model is as follows:
The different developmental tube A of internal diameter is connected with developmental tube B, and developmental tube A is provided with a gap, places and compress shell fragment in gap; The outside surface of developmental tube B is provided with insulating outer layer.
Described developmental tube A and developmental tube B is connected to one.
The end face of described developmental tube B is provided with groove, and the end face of developmental tube A is provided with the flange with groove match, and developmental tube A and developmental tube B is flexibly connected by flange and groove.
Described developmental tube A internal diameter 2.4mm, external diameter 4.0mm, wall thickness 0.8mm, long 20mm, developmental tube B internal diameter 4.0mm, external diameter 5.6mm, wall thickness 0.8mm, long 20mm.
The utility model has the advantages of as follows:
1, the utility model test plug volume is little, easy to carry, and size with the contact pin perfect cooperation on secondary plug, can not can touch other contact pins by mistake.
2, during test plug test, be sleeved on contact pin outside surface, test plug and contact pin surface of contact be " face " and the contacting of " face ", and contact well.
3, test plug is provided with compression shell fragment, and clamping force is strong, can not loosen, come off.
4, test plug can adopt flexible connection, when developmental tube A and developmental tube B has any one to damage, only changes corresponding one, replaces, provide cost savings without the need to entirety; And developmental tube A and developmental tube B adopt and be flexibly connected, also facilitate the contact pin of different size to test, the developmental tube A that developmental tube A can replace corresponding size according to pin diameter is combined with developmental tube B, flexible and convenient to use.
5, test plug practicality is extremely strong, and be convenient to promote the use of, actual application value has a extensive future.

In figure, 1, developmental tube A, 2, compress shell fragment, 3, insulating outer layer, 4, developmental tube B, 5, contact pin, 6, p-wire termination.
Embodiment
embodiment 1
As shown in Figure 1-2, the copper developmental tube A that internal diameter is different and copper developmental tube B is connected to one, and developmental tube A is provided with a gap, places and compress shell fragment 2 in gap; The outside surface of developmental tube B is provided with insulating outer layer 3.Described developmental tube A internal diameter 2.4mm, external diameter 4.0mm, wall thickness 0.8mm, long 20mm, developmental tube B internal diameter 4.0mm, external diameter 5.6mm, wall thickness 0.8mm, long 20mm.
embodiment 2
The end face of described developmental tube B is provided with groove, and the end face of developmental tube A is provided with the flange with groove match, and developmental tube A and developmental tube B is flexibly connected by flange and groove.Other structure is with embodiment 1.
The utility model is accumulative carries out 10kV wheelbarrow switch mechanical characteristic test 183 groups.Adopt Special test plug, add up to save time 25 hours, save time 8.19 minutes for average single group, efficiency improves more than 80%.Due to advantages such as its volume are little, easy to carry, the grafting goodness of fit is high, fastness is good, obtain the consistent favorable comment of site work personnel.
