The high-voltage unit body is installed on one side of the base, and a moving assembly is arranged on the other side of the base opposite to the one side. This can reduce the volume and weight of the device and facilitate movement during testing. Two or more side plates are detachably connected to the side of the base, and the two or more side plates and the base form a protective shell with an opening. The high-voltage unit body is located in the inner cavity of the protective shell, and a protective cover is arranged on the opening of the protective shell. This can protect the device during transportation, avoid damage to internal components due to bumps during transportation, prolong the service life of the device, and ensure the safety of the device during use, making it more portable and flexible for on-site testing.
