In addition, the non-test side needs to be Manual shorting. At present, when the transformer capacity test is carried out on site, whether the short-circuit clamp is in good contact, safe, reliable and firm is a relatively critical work. Especially when the transformer capacity test is carried out on the outdoor bench, due to the high position of the transformer installed on the bench, the electrical test personnel need to manually short-circuit the non-test end of the low-voltage side through the high-altitude operation to short-circuit the short-circuit wiring of the electrical test. Because the current short-circuit terminal clip can only be tightened by the tester's hand, often in the test process, poor contact often occurs, resulting in unsuccessful test and low work efficiency, requiring electrical testers to repeatedly perform high-altitude operations, resulting in increased electrical tests. Personnel safety risk; in addition, the short-circuit terminal clip is not firm and easy to fall off from high altitude, which also brings serious personal safety hazards to the electrical test personnel on the ground.
