Compression clamp for solar battery attenuation test

Abstract

The invention discloses a compression clamp for a solar battery attenuation test, which consists of a left rocker arm, a lift rocker arm, a pin shaft, a bracket, a compression spring and an elastic fastening sleeve, wherein the pin shaft is fixed on the bracket; the left and the right rocker arms are symmetrically sleeved on the pin shaft through pin holes; the bracket is fixed on an exposing bracket by screws; the bracket can rotate relative to the screws; the compression spring is arranged between a straight-lever handle of the left rocker arm and the straight-level handle of the right rocker arm; and the elastic fastening sleeve is arranged between the top of a straight-lever handle of the rocker arm and the top of the straight-level handle of the right rocker arm. The compression clamp is designed with a two-wing structure and one compression clamp can clamp two adjacent batteries, so that the whole structure is compact; the bracket is rotationally fixed on the exposing bracket by the screws; clamping plates on the left rocker arm and on the right rocker arm can quickly deviate from the battery when the battery is placed and taken out, so that the battery can be taken out and replaced conveniently; and thus, the battery is prevented from damages.

Description

technical field [0001] The invention relates to a solar cell testing device, in particular to an exposure rack in the solar cell attenuation testing device. Background technique [0002] In recent years, as a clean and environmentally friendly new energy source, solar cells have been more and more widely used. The service life of solar cells is the main technical indicator to measure the quality of batteries. The size of the attenuation. In the actual production process, people usually use the open-air light test method to test it. The solar cells are placed directly outside, and the solar cells are irradiated with natural sunlight. The attenuation is evaluated by comparing the power of the solar cell. With this open-air light test method, the natural light received by the solar cell is very unstable, and the light intensity and light time vary with the natural weather. People cannot control it. It is very long, and the test data obtained cannot be repeated, and the reliab...

AI Technical Summary

Problems solved by technology

In the actual production process, people usually use the open-air light test method to test it. The solar cells are placed directly outside, and the solar cells are irradiated with natural sunlight. The attenuation is evaluated by comparing the power of the solar cell. With this open-air light test method, the natural light received by the solar cell is very unstable, and the light intensity and light time vary with the natural weather. People cannot control it. It is very long, and the test data obtained cannot be repeated, and the reliability is poor. At the same time, the cells are not protected when they are placed outdoors, and they are easily broken by the wind.

At present, in the solar cell production industry, although people know that the service life is the main technical index to measure the quality of solar cells, due to the lack of specific testing standards, there is no credible testing equipment, and because users attach great importance to this index, manufacturers only Promise to users that its service life can reach 20 years, but there is no corresponding test data to prove it
