Description

Rolling EL camera support

Technical Field

the utility model relates to a can rolling EL (electroluminescence) camera support belongs to photovoltaic module test field.

Background

the detection of the photovoltaic module el (electroluminescence) is called electroluminescence detection, and is a detection technology for judging the defect of the module according to the electroluminescence principle of the silicon material. The specific implementation method is that a forward current which is 1-1.5 times of Isc (component nominal short circuit current) is introduced into the crystalline silicon cell component through an external power supply, the silicon chip can emit infrared light of 1000-1100nm, meanwhile, the EL camera can capture the light in the wavelength range, image and record the light on equipment such as a computer and the like, and whether various defects exist in the component is judged according to the image.

EL testing is one of the most common and important ways to assess photovoltaic module performance, photovoltaic plant construction and operation and maintenance quality. The traditional EL testing system adopts a tripod as a supporting system of an EL camera, and the specific structure is as shown in fig. 1, and the EL testing system comprises an EL camera 1, a spherical holder 2, a tripod 3, a sample to be tested 4 (photovoltaic module), and a mounting bracket 5 for fixing the photovoltaic module.

in actual shooting, a tripod 3 is mounted and erected on the ground or other support erecting surfaces, and a spherical pan/tilt head 2 is mounted on the top end of the upper side of the tripod 3. The EL camera 1 is mounted on the spherical pan/tilt head 2, and the test angle of the EL camera 1 is adjusted. After the angle adjustment is completed, the tripod 3 is adjusted to the height required by the test, and then the tested sample 4 is shot according to the test instruction of the EL equipment.

The existing EL test system and the shooting mode thereof have the following defects:

1) Poor stability of ground test: the stability of the tripod erected on the ground is greatly influenced by the flatness of the ground and sundries such as weeds, and even under special conditions (such as weeds growing in spring and summer), the tripod cannot be stably erected on the ground for testing.

2) The image distortion is severe: if the upper row of photovoltaic modules is shot by the equipment shown in fig. 1, the photovoltaic modules cannot be shot perpendicular to the centers of the modules, and the trapezoidal distortion of images is inevitably generated due to the shooting angles.

3) Frequent focusing: because the distance between the assumed position of the bracket and the tested component changes, the tester is generally required to decide whether to focus again before each test according to the situation, otherwise, the defocusing result can be generated.

4) Maximum test height constraint: for power stations which are installed on higher basic supports, such as agricultural light complementation and the like, the power stations cannot be tested due to the height restriction of the tripod.

5) And (3) limiting the minimum stent expansion area: for power stations without vacant flat surfaces for erecting tripods such as special roof photovoltaic and the like, the test cannot be carried out due to the restriction of the requirement of the minimum unfolding area of the tripods.

6) Definition of water test: for power stations requiring sailing and entering a photovoltaic area, such as fishing light complementation, the image definition of EL shooting can be greatly influenced due to the vibration of the ship body and the water surface.
