Voltage-withstanding detection device and method

The invention belongs to the field of automatic voltage-withstanding detection of an automatic metering terminal and a three-phase electric energy meter, and discloses a voltage-withstanding detectiondevice. The device comprises a rack. The rack is provided with a power supply and the voltage-withstanding detection device at the bottom, and a workbench at the top. A plurality of connection devices capable of sliding relative to the workbench are transversely arranged on one side of the workbench at intervals. A lifting mechanism is arranged in the rack. The lifting mechanism drives a corresponding to-be-detected part to ascend to a corresponding connection unit. According to the voltage-withstanding detection device, not only the calibration of the three-phase electric energy meter but also the calibration of the automatic metering terminal can be carried out, so that various detection requirements can be met, the site is saved, and the utilization rate of the device is improved.
