Description
Technical field
The utility model relates to the technical field of electric power overhaul test, relates in particular to a kind of direct-current resistance tester for transformer.
Background technology
As everyone knows, in electric system, transformer is as important potential device at present, no matter be transformer that newly dispatch from the factory or operating, all will carry out the direct current resistance test according to the requirement of rules, because of the wiring group difference of transformer, the test connection method is also different.(Y connection need connect 0A, 0B, 0C, and the wiring of △ shape needs to connect AB, BC, CA).Existing instrument for measuring DC resistance only has two extension lines, can only test one group of coil wherein during each test, the test of other coil can only complete by the method for artificial replacing wire clamp, because the transformer extension line is very high apart from ground, need constantly upper and lower transformer back and forth of testing crew in changing the process of wire clamp, artificial prolongation the direct current resistance test period.And, while changing wire clamp, the adding of wire clamp pinched position, dynamics, surface of contact all can be because human factor causes difference at every turn, test findings certainly will be also different, so just likely cause testing crew according to test findings, the winding performance erroneous judgement of transformer to be broken.In addition, when changing wire clamp, Transformer Winding may fully not discharged, and can cause personal injury to testing crew.
The utility model content
The purpose of this utility model is to provide a kind of energy fast and reliable and time saving and energy saving direct-current resistance tester for transformer.
For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of direct-current resistance tester for transformer, comprise casing and connecting line, described casing is provided with lead-in wire, on described lead-in wire, is provided with change-over switch, and described connecting line is connected with described lead-in wire by change-over switch.
Described change-over switch is 2.
Described connecting line is 3.
A kind of transformer dc high speed tester of the present utility model is provided with change-over switch on described lead-in wire, described connecting line is connected with described lead-in wire by change-over switch, described connecting line is 3, with connecting line, with the extension line of high voltage side of transformer or low-pressure side, be connected, by two switches, with instrument for measuring DC resistance, be connected, utilize the position of the switch transformation reach the measurement of respectively organizing coil resistance in transformer, thereby reduced the step of artificial replacing wire clamp, shortened test period, improved test accuracy, and then increased work efficiency.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of direct-current resistance tester for transformer of the present utility model, comprise casing 1 and connecting line 2, described casing is provided with lead-in wire 3, be provided with change-over switch 4 on described lead-in wire, described connecting line 2 is connected with described lead-in wire 3 by change-over switch 4, and described change-over switch is 2, and described connecting line is 3.
A kind of transformer dc high speed tester of the present utility model is provided with change-over switch on described lead-in wire, described connecting line is connected with described lead-in wire by change-over switch, described connecting line is 3, with connecting line, with the extension line of high voltage side of transformer or low-pressure side, be connected, by two switches, with instrument for measuring DC resistance, be connected, utilize the position of the switch transformation reach the measurement of respectively organizing coil resistance in transformer, thereby reduced the step of artificial replacing wire clamp, shortened test period, improved test accuracy, and then increased work efficiency.
