Description

A performance test bench for air-gap solid-sealed poles

Technical Field

The utility model relates to the technical field of solid-sealed pole performance detection, in particular to a performance test bench for air-gap solid-sealed poles.

Background Art

The solid-sealed pole is an important component in the indoor high-voltage AC vacuum circuit breaker. It is a vacuum interrupter and conductive copper parts that are solidified into a whole by pouring epoxy resin. Therefore, the performance of the solid-sealed pole directly affects the entire power transmission and distribution system. In order to ensure that all performance parameters of the indoor high-voltage AC vacuum circuit breaker can meet the technical indicators, the performance parameters of the solid-sealed pole must be tested one by one, and the self-closing force and loop resistance under rated pressure of the solid-sealed pole are its important technical parameters.

The patent with publication number CN202758001U discloses a detection device for the loop resistance of a sealed pole, which includes a test bench, one end of which has a fixing for fixing to the sealed pole to be tested, and a pressurizing component is also provided on the test bench, the pressurizing component includes a support arm fixed on the test bench and a rotating rod with an external thread, and the end of the rotating rod close to the sealed pole is connected to a pressure sensor. During specific operation and use, the sealed pole is first fixed to the fixing, and then the fixing is plugged and fixed on the test bench. The rotating rod driven by external force moves downward so that the rotating rod contacts the insulating pull rod. External force is applied to the pressurizing component so that the rotating rod forms a certain pressure on the insulating rod. The tester obtains the current test conditions from the pressure display and determines whether the loop resistance of the sealed pole meets the standard.

However, during the operation of this performance detection device, the sealed pole needs to be fixed to the fixing part by bolts, and the fixing and disassembly are not convenient, which greatly reduces the performance detection efficiency. At the same time, one test device can only test one sealed pole at a time, which is not convenient for continuous detection. The air-gap sealed pole performance test platform and test method taking into account the ambient humidity disclosed in the patent with publication number CN115792535A also have the problem that only one air-gap sealed pole can be tested when testing the loop resistance of the air-gap sealed pole, and multiple air-gap sealed poles cannot be tested continuously. Therefore, it is urgent to propose a new performance test platform for air-gap sealed poles.
