The device includes a steady state light source system, a light cover positioning system connected with a light cover as well as a thermal imaging positioning system and a display system which are connected with a thermal imaging system, wherein the steady state light source system, the light cover positioning system, the thermal imaging positioning system and the display system are connected with a control system respectively. According to the device of the utility model, the steady state light source system is utilized to simulate a sunlight irradiation environment to irradiate the solar assembly; the light cover is utilized to simulate a situation in actual use that the solar assembly is occluded; the thermal imaging system is utilized to determine local hot spots of the solar assembly; and therefore, the device of the utility model can intuitively obtain the shape, position and size of the hot spots, and can determine the situation of the local hot spots in the actual use when battery sheets are occluded.
Description
Technical field
The utility model relates to a kind of device that detects hot spot, more particularly, is that a kind of thermal imagery that utilizes detects the device that the solar components partial occlusion causes hot spot.
Background technology
The hot spot problem of solar components when reality is used had a strong impact on the power of photovoltaic plant, can cause for a long time assembly to damage, and even can develop into the safety problems such as fire, is the major issue that solar components must be got rid of.
Because the problem of local hot spot is not will occur, also be not easy to observe intuitively, so that easily hot spot hidden danger occur at once.
The shortcoming of prior art: prior art, by the test of IV curve, is inferred the cell piece that hot spot is arranged, and can't obtain intuitively the shape of hot spot, position, size etc.; Prior art, by the test of illumination, is not used light shield, the local hot spot in the time of can't determining assembly cell piece is blocked when reality is used.
The utility model content
The problems referred to above due to prior art, the utility model proposes a kind of thermal imagery that utilizes and detect the device that the solar components partial occlusion causes hot spot, its purpose is to obtain intuitively the shape, position of hot spot and size etc., and the local hot spot of definite assembly when cell piece is blocked when reality is used.
The utility model addresses the above problem by the following technical programs:
A kind of thermal imagery that utilizes detects the device that the solar components partial occlusion causes hot spot, it comprises thermal imaging positioning system and the display system that is connected with the light shield positioning system of light shield and is connected simultaneously a thermal imaging system by a stable light source system,, and described stable light source system, light shield positioning system and thermal imaging positioning system all are connected with a control system with display system.
Use the irradiation of stable light source system simulation sunshine to solar components.
Use light shield to solar components block analog solar assembly generation hot spot the time block.
Described stable light source system is positioned at the positive side of solar components, and thermal imaging system is positioned at solar components reverse side one side.
Use thermal imaging system to detect the hot spot of solar components.
Because the utility model adopts stable light source system simulation solar illuminating ambient illumination solar components, use situation about being blocked in the actual use of light shield simulation, use thermal imaging system to determine the local hot spot of assembly, make device of the present utility model can obtain intuitively the shape, position of hot spot and size etc., and the local hot spot situation can determine assembly cell piece is blocked when reality is used the time.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with embodiment, describe the utility model in detail.
Shown in Figure 1, be structural representation of the present utility model.In figure, utilizing thermal imagery to detect the solar components partial occlusion causes the device of hot spot to comprise thermal imaging positioning system 4 and the display system 5 that is connected with the light shield positioning system 3 of a light shield 6 and is connected simultaneously a thermal imaging system 7 by a stable light source system 2,, described stable light source system 2, light shield positioning system 3 and thermal imaging positioning system 4 all are connected with a control system 1 with display system 5
Described stable light source system is positioned at the positive side of solar components, and described thermal imaging system is positioned at solar components reverse side one side.
In the utility model, use the irradiation of stable light source system simulation sunshine to solar components.Use light shield to solar components block analog solar assembly generation hot spot the time block.Use thermal imaging system to detect the hot spot of solar components.
Principle of work of the present utility model is: stable light source system 2 is at the control Imitating solar illuminating ambient illumination solar components of control system 1; Light shield positioning system 3 is in the front that the control lower-pilot light shield 6 of control system 1 blocks solar components 8 successively, the simulation situation that solar components 8 is blocked when reality is used; The thermal imaging positioning system that is positioned at solar components 8 back sides moves the thermography picture that thermal imaging system 4 obtains the part of the solar components 8 blocked, and by relatively, confirms hot spot shape, position, size etc., and outputs on display system 5.
This device not only facilitates the confirmation of product turnout quality assurance, also is applicable to the adjustment reference of assembly or cell piece technique.
Should be understood that these embodiments only are not used in restriction scope of the present utility model be used to the utility model is described.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
