The invention relates to main transformer test equipment in a power industry, particularly discloses a comprehensive test case for a transformer, and aims at solving the technical problems of low work efficiency and existence of potential safety hazards caused by moving the transformer up and down to wire in the test of the existing transformer. The comprehensive test case for the transformer comprises a test box body, wherein high-voltage, medium-voltage and low-voltage binding posts are arranged on a front panel of the box body; high-voltage, medium-voltage and low-voltage binding posts are also arranged on a back panel of the box body; the high-voltage binding posts on the two panels are connected through an internal connection wire inside the test box body; the medium-voltage binding posts and the low-voltage binding posts are also connected through internal connection wires inside the test box body; withdrawal shielding covers capable of shielding the upper parts and the left sides and the right sides of binding posts are respectively arranged on the front side and the back side of the test box body corresponding to high-voltage binding posts, medium-voltage binding posts and low-voltage binding posts. After the device is used, the climbing times is reduced when a main transformer test is carried out, the test time is shortened, meanwhile, the potential safety hazards of personnel are also reduced, the work efficiency is improved, and the personal and equipment safety is protected to the maximal extent.
Description
technical field [0001] The invention relates to a main transformer test device in the electric power industry, in particular to a transformer comprehensive test box. Background technique [0002] There are many test items for transformers. Taking the specific dielectric loss test as an example, the test personnel should wear safety belts to climb the transformer. The maximum distance between the high, medium and low voltage sides of a large transformer is 7 meters. Then perform wiring to test the dielectric loss of the high voltage to the ground. Considering the safety distance between personnel and equipment (220kV is 3 meters, 110kV is 1.5 meters, 35kV is 1 meter), the wiring workers must get off the 6-meter-high transformer, To ensure personal safety. The same process is used to test medium-voltage to ground and low-voltage to-ground dielectric losses. In addition, there are high-voltage and medium-voltage bushing dielectric loss tests. Only one test item needs to be cl...
