GIL pipeline pressure resistance test method

A GIL pipeline pressure resistance test method comprises the steps that a roller conveyor is used for conveying GIL pipeline modules, a transferring device is used for moving the GIL pipeline modules to a picking station, the roller conveyor is used for being matched with a first baffle mechanism and a second baffle mechanism to convey the next GIL pipeline module to a preparation position, a clamping device is used for clamping the GIL pipeline modules, and the GIL pipeline modules are conveyed to a test station. The method comprises the following steps: taking a GIL pipeline module, transferring the GIL pipeline module to a test station, clamping the GIL pipeline module by utilizing a clamping device, transferring the GIL pipeline module to the test station, filling sulfur hexafluoride gas into the GIL pipeline module, starting a test power supply device, carrying out a voltage withstanding test on the GIL pipeline module, starting the test power supply device, and carrying out the voltage withstanding test
