Abstract

The invention relates to a wet electric leakage test device for a solar-energy photovoltaic assembly. The device includes a support frame, a water sink, four pressure control spraying devices and water draining devices. The support frame is of a four-foot support type and omni-directional wheels are arranged at the four feet. The water sink is rectangular in shape and is provided with an opening at an upper end and is fixed on the support frame. The pressure control spraying devices are arranged at an outer side of the water sink. And the water draining devices are arranged at the bottom of the water sink. Compared with the prior art, the wet electric leakage test device for the solar-energy photovoltaic assembly has the advantages of being simple in structure, moderate in height, convenient to move and high in measurement precision.

Description

technical field [0001] The invention relates to a test device, in particular to a solar photovoltaic component wet leakage test device. Background technique [0002] The traditional wet leakage test method of photovoltaic modules is simple, and there is no professional equipment and devices to carry out the test. The operation is troublesome and dangerous, resulting in inaccurate test results. Because there is no specific container and test equipment, many laboratories omit this test item and cannot carry out related tests, resulting in a blank test item. In order to meet the needs of the test for this type of device, this device was developed in combination with the test conditions stipulated in IEC 61215 "Design, Qualification and Finalization of Crystalline Silicon Photovoltaic Modules for Ground Use". It is used for the wet leakage test of photovoltaic modules to detect the impact of moisture caused by rain, fog, dew or melting snow entering the interior of the module ...
