Description

Technical Field

[0001] The invention relates to the technical field of performance detection of insulating ring main unit accessories, and in particular to a performance detection device for insulating ring main unit accessories. Background Art

[0002] The insulated ring main unit is a distribution equipment used in the power system. It is mainly used for the distribution, control and protection of the medium voltage power grid. It branches and controls the power system and is an important part of ensuring the safe movement of the power grid. During use, the plug and unplug heads of the ring main unit are prone to problems. Therefore, it is necessary to test the performance of the plug and unplug test.

[0003] Traditional testing devices generally only perform plugging and unplugging tests on the sleeve and the front connector. Existing plugging and unplugging force testing machines are all single-detection machines, and the improved testing machines only add workstations to test the life of multiple connector products. When it is necessary to perform plugging and unplugging force tests on the sleeve and the front connector, the front connector needs to be fixed, and the sleeve and the front connector need to be repeatedly plugged and unplugged. Finally, the tightness of the connection between the sleeve and the front connector is observed to determine the plugging and unplugging performance. Therefore, when it is necessary to perform plugging and unplugging force tests on the sleeve and the front connector, the front connector and the rear connector, the front connector and the stress cone on the wire, and the rear connector and the stress cone on the wire, the test pieces need to be fixed on the corresponding workstations and fixed, and then plugging and unplugging tests are performed in pairs. However, in actual use, the sleeve, the front connector, the rear connector and the stress cone on the wire are plugged in and used together. Therefore, it is not practical to only test the connection between two of them, and the test results are not representative. Summary of the invention
