Novel withstand voltage insulation testing device for crystalline silicon photovoltaic module

Abstract

The invention relates to a testing device in the photovoltaic field, in particular to a novel withstand voltage insulation testing device for a crystalline silicon photovoltaic module. The novel withstand voltage insulation testing device for the crystalline silicon photovoltaic module comprises a withstand voltage insulation tester, a fixture, connector matching plugs and connecting wires and is characterized in that the fixture adopts a mode of combining a cylindrical chuck and a platy chuck and is connected to the cathode end of the withstand voltage insulation tester through the connecting wire; the connector matching plugs adopt double plugs matched with the anode and cathode connecting ends of a module connecting wire and are connected to the anode end of the withstand voltage insulation tester through the connecting wires; the diameter of the cylindrical chuck of the fixture is equal to those of a grounding hole and a water leakage hole of the photovoltaic module; when withstand voltage insulation testing is carried out by the device, the testing aim can be fulfilled without carrying out short-circuit processing on the connecting wire of the photovoltaic module, or stripping off wire skin or polishing an aluminium frame.

Description

technical field [0001] The invention relates to a test device in the photovoltaic field, in particular to a novel crystalline silicon photovoltaic module withstand voltage insulation test device. Background technique [0002] Crystalline silicon photovoltaic modules need to pass TUV certification to enter the North American market. This certification requires manufacturers of crystalline silicon photovoltaic modules to conduct grounding and withstand voltage insulation tests during the production process. After short-circuiting, peel off the wire sheath to expose the wire, clamp the wire with the positive crocodile clip of the DC insulation tester, and after partially polishing the aluminum frame of the crystalline silicon photovoltaic module, clamp it with the negative crocodile clip of the DC insulation tester Aluminum frame, such a test method has the defect of damage to the aluminum frame and connecting wires of the crystalline silicon photovoltaic module.
