Description

Technical Field

[0001] The utility model relates to the technical field of high-current testing, in particular to a connecting copper bar structure of a high-current testing device. Background Art

[0002] When most testing institutions conduct the radiated emission test of universal circuit breakers, it does not fully meet the standard requirements. Since the test sample should be placed on a turntable and obtain low-voltage high-current power supply from a power supply device through a thick and soft connecting wire, and the turntable needs to rotate 360°, the thick and soft wiring will inevitably get entangled, thus easily causing a short circuit. This necessarily brings the problem of how to place the large-sized power supply device when the test sample rotates.

[0003] In the existing patent technology CN103487751A, a low-voltage high-current rotating test device is described. The device includes an anechoic chamber, a turntable is arranged in the anechoic chamber, an insulating test table is arranged on the turntable, the test sample to be tested is arranged on the insulating test table, a turntable center hole is arranged in the center of the turntable, a copper bar is arranged in the turntable center hole, one end of the copper bar is connected to the power supply end of the power supply device, and the other end is connected to the test sample through a soft connecting wire. The power supply device is arranged in a shielding chamber. The present invention places the low-voltage high-current power supply device underground the turntable and connects it to the test sample through the controllable lifting of the copper bar in the hollow shaft area of the turntable. The turntable rotates ±180°, which fully meets the essential requirements of the radiated emission test for examining the maximum radiated interference surface of the test sample. At the same time, the overall cost of the customized center hollow shaft turntable and the copper bar is much lower than that of the double-layer turntable, having great advantages in manufacturing cost, and the maintenance of the power supply device is also extremely convenient.
