Abstract
The utility model discloses a device for testing the three-phase direct-current resistance of a power transformer at the same time, which comprises a resistance test device. The resistance test device is provided with an SCM and connected with a direct-current voltage and current stabilizing device. Because the direct-current voltage and current stabilizing device is connected with the resistance test device, the resistance test device can be used for testing three ways of tapping windings of the transformer at the same time. The whole testing process is controlled by the SCM, and the test data is stable and accurate. The device is easy to operate, is suitable for different test environments and has perfect counter electromotive force protection function and site anti-interference capability.
Description
Technical field
The utility model belongs to the power test technical field of tools, is specifically related to a kind of device of testing power transformer three-phase dc resistance simultaneously.
Background technology
The direct current resistance of power transformer is measured and state analysis; Especially measurement and the analysis to low resistance is a difficult problem, needs one the tunnel one the tunnel to test usually, not only inefficiency; And constantly change measurement circuit trouble very; But, there are not effective better method of testing and testing tool, bring very big inconvenience to power test.
The utility model content
The purpose of the utility model is to avoid above-mentioned weak point of the prior art, and a kind of convenient test is provided, the device of test power transformer three-phase dc resistance when test data is accurate, easy and simple to handle.
The technical scheme that purpose adopted that realizes the utility model is: a kind of device of testing power transformer three-phase dc resistance simultaneously; Comprise the resistance test device; Said resistance test device is provided with single-chip microcomputer, and said resistance test device is connected with the DC voltage stabilization and current stabilization device.
Because the utility model utilizes the DC voltage stabilization and current stabilization device to be connected with the resistance test device; Make the resistance test device to test simultaneously transformer tap winding three road, the test overall process is accomplished by Single-chip Controlling, and is simple to operate; Test data is stable; Accurately, suitable different test environment has perfect back electromotive force defencive function and on-the-spot antijamming capability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model.
