Walk-in test box for ultraviolet aging test of photovoltaic module

Abstract

The invention relates to a walk-in test box for an ultraviolet aging test of a photovoltaic module, which comprises a test box, an ultraviolet lamp tube arranged in the test box, and a test platform for placing a photovoltaic module to be tested. Monitoring equipment is also arranged in the test box; the monitoring equipment comprises an ultraviolet irradiance detection probe and a digital monitoring display; the ultraviolet irradiance detection probe comprises a UV-A probe and a UV-B probe; the UV-A probe is used for detecting the irradiation amount for the wavelength of 320 to 400 nm; the UV-B probe is used for detecting the irradiation amount for the wavelength of 280 to 320 nm; the UV-A probe and the UV-B probe are arranged in the test box and are connected with the digital monitoringdisplay arranged outside the test box, and the digital monitoring display is used for receiving signals of the UV-A probe and the UV-B probe and displaying the irradiance detected by the UV-A probe and the UV-B probe. Compared with the prior art, the test capability can be improved, and the convenience of operation and maintenance can be improved.

Description

technical field

[0001] The invention relates to a test chamber, in particular to a walk-in test chamber for ultraviolet aging testing of photovoltaic modules. Background technique

[0002] Ultraviolet light (UV) only accounts for 5-7% of sunlight, but it is an important part of the weatherability test of photovoltaic modules. The UV pretreatment experiment is mainly used to simulate the damage to photovoltaic modules caused by ultraviolet radiation in sunlight when photovoltaic modules are placed outdoors for a long time. The UV aging test chamber is an aging test equipment that simulates light. According to IEC 61215-2:2016, MQT 10, the UV light source for the simulation test needs to be controlled at a wavelength of 280nm-400nm and the total irradiance intensity cannot exceed 250W / m 2 , among which the proportion of the wave band at 280nm-300nm should be 3%-10%. In order to meet this condition, the environmental chamber needs to have accurate monitoring devices to detec...
