Abstract: A wet leakage current test system for a photovoltaic component is disclosed having a liquid pool and a voltage-withstanding insulation tester as well as a first storage rack, a lifting actuator, a second storage rack, a drying apparatus and an electrical protection device; the first storage rack is arranged above the liquid pool, and is mechanically connected with the lifting actuator; 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, for blowing air to a front surface and a back surface of the photovoltaic component laid flat on the second storage rack; and the electrical protection device is in electrical signal connection with the voltage-withstanding insulation tester, for disabling a voltage output from the voltage-withstanding insulation tester in the case that the operator operates in a high voltage region, and/or for cutting off a power source of the voltage-wit

Abstract: Disclosed is a photovoltaic assembly, including a cooling platform for supporting the photovoltaic assembly to be cooled; a first high-temperature cloth unit provided on the cooling platform; a vacuum cover for forming a vacuum chamber together with the cooling platform, the vacuum chamber accommodating the photovoltaic assembly to be cooled; a second high-temperature cloth unit provided at a side of the vacuum cover facing the cooling platform; and a lifting bracket for driving the vacuum cover lift or fall. In the above-mentioned photovoltaic assembly, the vacuum cover is driven and lifted by the lifting bracket, and forms a vacuum chamber together with the cooling platform. The vacuum chamber creates a pressure cooling effect for the photovoltaic assembly to be cooled. In turn, the appearance defects may be reduced when the photovoltaic assembly is cooled to the normal temperature.
