[0002] The power frequency test of high-voltage outlet bushings is generally divided into open type and interface type. These two test methods are mainly based on the actual use scenarios and test requirements of high-voltage outlet bushings.

[0003] Among them, in the open power frequency test, the high-voltage outlet bushing is placed in an open test environment, and a power frequency voltage of a certain frequency and amplitude is applied to detect the electrical performance of the high-voltage outlet bushing under the rated voltage. Although this test method can directly reflect the performance of the high-voltage outlet bushing itself, due to the large area of ​​the site required during the experiment, and the test process of the test product, because it cannot fully simulate the environmental conditions of the actual operation of the high-voltage outlet bushing, the results of the high-voltage outlet bushing are easily interfered by various factors such as external scenes; at the same time, during the test process, multiple wires need to be connected to the high-voltage outlet bushing, which takes a long time, resulting in low test efficiency of the high-voltage outlet bushing. In the interface power frequency test, the high-voltage outlet bushing is connected to the test equipment through an interface transformer to form a complete circuit system, and then by applying a power frequency voltage, the electrical connection performance, insulation coordination, etc. between the high-voltage outlet bushing and the interface transformer can be tested. This method requires a small site, is less disturbed by the external environment during the test of the test product, and has a short preparation time for the experiment, so the test efficiency is high. It gradually occupies the dominant test method in the power frequency test of the high-voltage outlet bushing. This test method can more comprehensively evaluate the performance of the high-voltage outlet bushing in actual operation, but during the test, it is necessary to ensure the stability and convenience of the connection between the outlet bushing and the interface transformer.

[0004] At present, in order to ensure the stability and convenience of the connection between the outlet bushing and the interface transformer, a support frame is usually set at the bottom of the high-voltage outlet bushing. The existing support tooling includes a placement platform. Four connecting columns are set on the bottom end face of the placement platform. Adjusting columns are slidably connected to the connecting columns. The adjusting columns and the connecting columns are limited by pins. Although the device can adjust the placement height of the outlet bushing, the four adjusting columns need to be adjusted separately and laboriously. In addition, during the adjustment process, the placement platform is prone to tilt and then topple over, which can easily cause injuries to the staff. Utility Model Content
