Single-sweep irradiance test support for ultraviolet aging test box

Abstract

The invention discloses a single-sweep irradiance test support for an ultraviolet aging test box. The single-sweep irradiance test support for the ultraviolet aging test box comprises rollers, a bottom frame, a vertical frame, two lead screws, a belt pulley, a synchronous belt, two moving installation blocks, a leveling rod, a plurality of irradiance probes, and a lifting motor; the vertical frame is fixed on the upper end face of the bottom frame; two ends of each of the two lead screws are fixed on the vertical frame through a bearing pedestal and are vertical to the bottom frame; the upper ends of the two lead screws are connected through the synchronous belt; the moving installation blocks are rotatably arranged on the two lead screws; two ends of the leveling rod are fixed on the two moving installation blocks respectively; the plurality of irradiance probes are arranged on the leveling rod at equal intervals; and the lead screws are driven by the lifting motor. During testing, the leveling rod scans up and down once so as to accurately obtain the ultraviolet light irradiance in the ultraviolet aging test box; the higher the installation intensity of the irradiance probes on the leveling rod, the more accurate the measured data is; and the single-sweep irradiance test support can obviously improve the irradiance test accuracy of the ultraviolet aging test box.

Description

Technical field: [0001] The invention relates to ultraviolet aging test equipment for solar battery components, in particular to an irradiance test frame for an ultraviolet aging test box for solar battery components. Background technique: [0002] Solar cell modules are placed outdoors for a long time so that the cells absorb sunlight and convert it into electrical energy for transmission to the grid. However, the ultraviolet rays in the sun will age the packaging materials of the components, thereby reducing the service life of the components. In order to simulate the real situation and test the performance of the packaging materials of the solar cell components, according to the International Electrotechnical Commission (IEC) standard, the solar cell components are in the Ultraviolet (UV) irradiation pretreatment must be carried out before the thermal cycle / wet freeze cycle test to determine the UV attenuation of the relevant materials and adhesive connections. For this ...

Problems solved by technology

[0003] Before performing the light test on the battery components, the irradiance of ultraviolet light in the UV aging test box must be corrected first, in order to ensure that the irradiance of ultraviolet light of the components during the test meets the requirements of the International Electrotechnical Commission (IEC) standard The current general method is to place a UV irradiance test frame in the UV aging test box. The UV irradiance test frame simulates the light conditions of the battery components to be tested in the UV aging test box, and its size is the same as that of the battery to be tested. The components are equivalent, and the erection position of the ultraviolet irradiance test frame is the same as that of the battery component to be tested. Multiple irradiance probes are used to determine the irradiance of ultraviolet light in the UV aging test chamber through these fixed irradiance probes. This kind of ultraviolet irradiance test frame has a simple and practical structure, but its measurement accuracy is low and cannot Accurately determine the irradiance of ultraviolet light in the ultraviolet aging test chamber, the customer's trust in this test result is not high, so it is urgent to improve it so that it can more accurately reflect the ultraviolet light in the ultraviolet aging test chamber irradiance
