Abstract
The utility model discloses a general test cable used for a transformer test. The general test cable used for a transformer test solves the problem that when a transformer test is carried out by employing the technology of the prior art, corresponding connection cables need to be respectively connected onto the transformer, and therefore total time spent on the routine transformer test is prolonged. The general test cable used for a transformer test comprise a voltage test core wire (7), wherein a low voltage common insulating layer (6) is arranged outside the voltage test core wire (7), a shielding layer (5) arranged outside the low voltage common insulating layer (6), an electric current test wire layer (4) is arranged outside the shielding layer (5), a high voltage silica gel insulating layer (3) is arranged outside the electric current test wire layer (4), a second shielding layer (2) is arranged outside the high voltage silica gel insulating layer (3), and a second high voltage silica gel insulating layer (1) is arranged outside the second shielding layer (2). The general test cable used for a transformer test saves work time spent on the transformer test.
Description
Technical field
A kind of test cable that the utility model relates to a kind of transformer to ultra-high-tension power transmission line to be used when testing.
Background technology
Transformer routine test project mainly contains: winding D.C. resistance; Winding insulation resistance and absorptance or polarization index; Tan δ and the electric capacity of winding; Capacitance sleeve pipe tan δ and electric capacity.When transformer is carried out each test, because instrument uses the lead-in wire disunity, therefore often doing a test all needs the staff to climb transformer, its high, medium and low voltage winding is carried out respectively short circuit, ground connection, change test connection, and after the change test connection, the wiring personnel must withdraw from transformer, when therefore transformer being tested at every turn, all need to receive respectively the connection cable of correspondence on transformer, testing crew needs the up and down transformer many times, causes transformer routine test T.T. to extend.
Summary of the invention
The utility model provides a kind of universal test cable for transformer test, has solved prior art when transformer is tested, and the connection cable of correspondence need to be received respectively on transformer, causes the problem that extends transformer routine test T.T..
The utility model is by the above problem of following solution:
A kind of universal test cable for transformer test, comprise the voltage tester heart yearn, be outside equipped with the common insulation course of low pressure at the voltage tester heart yearn, be outside equipped with screen layer at the common insulation course of low pressure, be outside equipped with testing current line layer at screen layer, be outside equipped with high pressure silicone insulation layer at testing current line layer, be outside equipped with the secondary shielding layer at high pressure silicone insulation layer, be outside equipped with the second high pressure silicone insulation layer at the secondary shielding layer.
Be connected with the voltage tester pincers in the end of voltage tester heart yearn, be connected with the testing current pincers in the end of testing current line layer, be connected with crocodile clip in the end of secondary shielding layer.
The utility model all is integrated together the test wire that all high-pottings need to be used after taking into full account shielding, only need the staff to climb twice, it is primary connection, once take out stitches, transformer just can be completed the routine test project of transformer, save the working time, improved work efficiency, reduced power off time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
