Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component testing, and particularly relates to an online testing device for a frameless photovoltaic component. [Background technology]

[0002] At present, the frame of conventional framed photovoltaic modules is provided with a frame tooling with test holes and connected to the photovoltaic modules. The test probe is connected to the frame tooling and connected to the negative pole of the test instrument, and the junction box is connected to the positive pole of the test instrument to form a test circuit, so that insulation, voltage resistance and other related tests can be performed; however, in recent years, frameless photovoltaic modules have appeared. Since the material of frameless photovoltaic modules is relatively soft, conventional testing equipment cannot fully fit the outer periphery of frameless photovoltaic modules, so the test efficiency is very low when performing insulation, voltage resistance and other related tests.

[0003] Therefore, in the prior art, there are related auxiliary test tools designed for the test of frameless photovoltaic modules. For example, patent publication number CN207183214U discloses an online insulation withstand voltage test tool for double-glass modules, including a test workpiece, which is pasted on the four sides of the double-glass module and connected to the negative pole of the test instrument through a test fixture. The junction box on the double-glass module is short-circuited and connected to the positive pole of the test instrument to form a test loop; the test workpiece includes a frame tool, a conductive elastic layer and a conductive tape arranged in sequence from the outside to the inside, and the test workpiece includes four parts with the same structure. When testing, the four parts of the test workpiece need to be fixed on four movable test fixtures respectively. After the photovoltaic module is in place, the four parts of the test workpiece are moved and fixed on the four sides of the photovoltaic module respectively, and are connected to the negative pole of the test instrument after being connected to the photovoltaic module, waiting for relevant tests. However, the test workpiece is provided with a frame tool covering the four sides of the photovoltaic module. Not only is the structure of the test tool itself complicated, but also when the photovoltaic module is tested online, the frame tool arranged on the four sides will make the layout and design of the conveyor line complicated.

[0004] Therefore, it is necessary to provide a frameless photovoltaic module online testing device to solve the above technical problems. [Utility Model Content]

[0005] The main purpose of the utility model is to provide a frameless photovoltaic module online testing device, which has a simple structure and an overall layout that occupies a small space, and can reduce test errors, improve test efficiency, and reduce test costs.
