Description
Technical field
The present invention relates to the wiring system of photovoltaic junction box and photovoltaic module, belong to photovoltaic module splicing application.
Background technology
The photovoltaic module of traditional mode, rosette integrated bypass diode is pasted onto the back side of photovoltaic module, bypasses two poles
Pipe is connected in parallel on above the battery strings of photovoltaic module, due to the existence of parallel circuit, as long as diode and battery strings have a road to be logical
The existence on road, whole circuit is exactly logical, it is impossible to determining the fault of diode or battery strings, existing market is installed and put into simultaneously
All there is the problem of the quality of the state having no idea to check each assembly in the photovoltaic module used, can only monitor each
The operating mode of the array of electric light photovoltaic assembly.
Diode produces heat, and the temperature in rosette region can rise rapidly, causes the temperature of local, assembly junction box position
Degree rises sharply, and (glass temperature such as assembly raises, and local can produce the stress of inherence, has and bursts apart to bring potential risks to assembly
Risk；Temperature is the highest runs into unexpected rainfall, and glass temperature is die-offed, and also has the risk burst apart；What winter, local was not melted is long-pending
Snow, is now the time period that the probability of bypass diode work is the highest, and the assembly glass temperature of rosette position is higher, top
The temperature of the snow water melted is close to 0 degree, abnormally dangerous).
The bypass diode majority of traditional assembly junction box is all in a welding manner, for the performance that assembly is overall,
Most assembly junction boxes use casting glue that the mode that junction box entirety embedding is lived is installed rosette.Connecing in the market
Line box also there is bypass diode also have the mode of a small amount of clamping that diode is installed, the most only on clamping is convenient, do literary composition
Chapter, therefore also exists contact area little, and contact resistance is big, and between pin and terminal, contact area is little, local when big electric current passes through
