Description
Technical field
The utility model relates to a kind of systems of cell piece temperature after test photovoltaic component encapsulating.
Background technique
Photovoltaic module by lamination after up to 140 DEG C of temperature, after C grade air-cooled circulation to solidify between be still 30 DEG C with
On, process component continues to solidify for -4 hours 3 hours using block and block dislocation stacked manner between solidification, and such stacked manner causes
So that the temperature among photovoltaic module is not radiated effectively, 25 ± 2 DEG C of normal temperature requirements can not be also down in IV testing process,
And then photovoltaic module power output is caused to reduce, it causes damages to company.
The more high then open-circuit voltage of cell piece temperature is lower, and component causes corresponding position cell piece to export because of local temperature raising
Efficiency decline causes voltage adaptation, and then component power output reduces.
Influence for temperature to power, IV tester can be compensated this by temperature compensation coefficient, and IV is tested
The test temperature that instrument obtains but derives from backboard temperature, is not the temperature that direct measurement cell piece obtains, and actual influence is electric
The temperature of pond piece power is the actual temperature of cell piece itself, in existing system, just can not directly be surveyed after photovoltaic component encapsulating
Cell piece is measured to obtain the actual temperature of cell piece.
Utility model content
Technical problem to be solved in the utility model is just to provide cell piece temperature after a kind of test photovoltaic component encapsulating
System.
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is as follows:
The system of cell piece temperature after a kind of test photovoltaic component encapsulating comprising a plurality of thermocouple wire and multi-route measuring temperature
The measurement end of instrument, thermocouple wire is fixed on cell piece, is directly contacted with cell piece, and thermocouple wire picks out end from photovoltaic module
In extend to outside and be electrically connected with multichannel temperature logger, the part of thermocouple wire being located in photovoltaic module is solid by fixing piece
It is scheduled on cell piece.
Further, fixing piece is High temperature-resistanadhesive adhesive tape.
Further, High temperature-resistanadhesive adhesive tape is tetrafluoro cloth rubber belt.
Further, the part that thermocouple wire is located in photovoltaic module is fixed on the back side of cell piece.
Further, the quantity of thermocouple wire is five.
Compared with prior art, the utility model has the following beneficial effects:
The utility model is divided into the temperature that multichannel directly measures cell piece by a plurality of thermocouple wire, realizes in photovoltaic module
After encapsulation also true cell piece temperature can be provided to photovoltaic module temperature uniformity is solved to the monitoring of cell piece actual temperature
Degree evidence, so as to preferably solve the problems, such as that local cell piece temperature is high, power loss caused by reducing therefore increases company's effect
Benefit.
