Wet leakage current test system for photovoltaic component

A wet leakage current test system for a photovoltaic component, comprising a liquid pool and a voltage-withstanding insulation tester, wherein the wet leakage current test system further comprises a first storage rack, a lifting actuator, a second storage rack, a drying apparatus and an electrical protection device,

• wherein the first storage rack is arranged above the liquid pool, mechanically connected with the lifting actuator, and configured to receive the photovoltaic component thereon, and the lifting actuator is configured to drive the first storage rack to descend into the liquid pool or ascend above the liquid pool;
• the drying apparatus is mounted on the second storage rack and configured to dry the photovoltaic component which moves from the first storage rack onto the second storage rack;
• and
• the electrical protection device is in electrical signal connection with the voltage-withstanding insulation tester, and configured to disable a voltage output from the voltage-withstanding insulation tester in the case that an operator operates in a high voltage region, and/or to cut off a power source of the voltage-withstanding insulation tester in an emergency.
