Abstract

The invention relates to a T-shaped end cable testing tool. The T-shaped end cable testing tool is composed of an eccentric screw and a single-core cable, wherein the two ends of the single-core cable are naked cores, threads are arranged on the outer surface of the naked core at one end, and the eccentric screw is screwed up on the threaded end of the naked core. A line pressing nose is clamped through the eccentric screw and the single-core cable, the labor intensity and operation risks for operation staff can be largely reduced, the testing time efficiency of a T-shaped end cable is improved, work procedure time is shortened, and the safety of the testing of the T-shaped end cable and the accuracy of testing data are guaranteed. Meanwhile, due to the fact that the naked cores of the single-core cable are tightly combined with a protective cover, no current is leaked, and testing errors are small. Besides, the T-shaped end cable testing tool is light in weight, convenient and flexible to use, safe, stable, convenient to operate, low in cost, simple to manufacture, high in practicability, and suitable for popularization and application.

Description

T cable test tool
Technical field
The present invention relates to a kind of electric system test instrument, be specifically related to a kind of T cable test tool, belong to electric power conveying technology field.
Background technology
Because the application of box type transformer, high pressure feeder pillar is increasingly extensive, high pressure feeder pillar and case become the important process that interior T cable testing become high-potting.Because the special construction of T cable and lack special test instrument, T cable testing become new problem in the high-potting work.
Traditional test method is to be connected with the line ball nostril in aluminum strip and the T head, and current-carrying part is drawn beyond the T head, could carry out applied voltage test to it, and the insulation distance of aluminum strip and the T draught animals is inadequate, and we solve Insulation Problems by usefulness pyrocondensation insulation tube.Therefore, in the past test method is deposited a lot of shortcomings and trouble:
At first be aluminum strip to be fixed on the cable end very difficult, not only length consuming time but also contact are not firm, because contact is bad, directly affect the accuracy of test figure.Secondly, aluminum strip and T-shaped casing wall insulation distance are inadequate, only depend on simply and install insulating sleeve additional at aluminum strip, can not fundamentally solve Insulation Problems, because because the dielectric strength of this insulating sleeve is little, leakage current is larger during test, and the security of test and the accuracy of data still can't be guaranteed.
Because the existence of the problems referred to above, T cable joined or during preventive trial, if test figure is defective, it is the problem of cable itself or manufacturing cable head that testing crew is difficult to judge, or the problem of test instrument and test method.Disconnected for avoiding erroneous judgement occurring, testing crew often wants repetition test for several times, and test is wasted time and energy, and it is disconnected erroneous judgement in a single day to occur, will cause the waste of material even the delay of duration.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of T cable test tool is provided, solve when at present T cable being carried out high-potting operation loaded down with trivial details, the problem such as the test figure accuracy rate is low.
Technical scheme of the present invention is as follows:
Formed by eccentric screw and single core cable; The two ends of single core cable are naked core, and wherein the naked core outside surface of an end is provided with screw thread, and eccentric screw is tightened on the termination of naked core screw thread.
Naked core length between described eccentric screw and the single core cable oversheath and T cable line ball nasal width are complementary.
The thickness of the thickness of described single core cable oversheath and T cable line ball nose is complementary.
The naked core of described eccentric screw and single core cable is good conductor of electricity.
The external thread of described eccentric screw internal thread hole and single core cable naked core is complementary.
The invention has the beneficial effects as follows: clamp the line ball nose by eccentric screw and single core cable, can greatly reduce operating personnel's labour intensity and operational risk, improve T cable testing timeliness, shortened job flow time, guarantee the security of T cable testing and the accuracy of test figure, simultaneously since between the naked core of single core cable and the oversheath in conjunction with closely, do not have Leakage Current, test error is little, in addition, light and flexible of the present invention, safety and stability, convenient operation, cost is low, make simply, practical, be suitable for applying.

Among the figure, 1, eccentric screw, 2, single core cable, 3, naked core, 4, screw thread, 5, oversheath, 6, a T cable, 7, the line ball nose, 8, connection terminal.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the present invention in detail.
Embodiment
As shown in Figure 1, formed by eccentric screw 1 and single core cable 2; The two ends of single core cable 2 are naked core, and wherein naked core 3 outside surfaces of an end are provided with screw thread 4, and the external thread of eccentric screw internal thread hole and single core cable naked core is complementary, and eccentric screw 1 is tightened on the termination of naked core 3 screw threads; The other end naked core of single core cable 2 is connection terminal 8, as the terminals of test; Leave oversheath 5 between two naked cores of single core cable, oversheath is insulator, and the thickness of the thickness of oversheath and T cable line ball nose is complementary, and remaining naked core length and T cable line ball nasal width are complementary between eccentric screw and the single core cable oversheath.The naked core of described eccentric screw and single core cable is good conductor of electricity.
Using method of the present invention is as shown in Figure 2, to hand single core cable oversheath of the present invention, with the eccentric screw eccentric side upwards, stretch in the insulation sleeve of T cable and pass from the hole of line ball nose, hook the line ball nose with lifting on the eccentric screw, eccentric screw and single core cable oversheath are clamped the line ball nose.A test clip of testing apparatus is clipped on the connection terminal of single core cable, and the another test clip is clipped in the testing requirements position can carry out high-potting.
