Abstract
The utility model relates to a photovoltaic array junction box; mulitpath anodes and cathodes of a photovoltaic array are connected with the junction box in parallel, and then are connected in parallel by a junction trunk; the mulitpath array inputs of the junction anode and cathode are connected into one path array in parallel; each path of the anodes and cathodes of the photovoltaic array is internally provided with a direct current fuse wire which is arranged in a fuse holder; the mulitpath anodes and cathodes of the photovoltaic array are connected in parallel into one path by the direct current fuse wire. The mulitpath anodes and cathodes of the photovoltaic array are connected in parallel, and then are connected with output terminals by a circuit breaker. The photovoltaic array junction box causes a photovoltaic grid-connected generating system to be safer and more reliable.
Description
Technical field
The utility model relates to a kind of photovoltaic array header box of being connected between battery component and the inverter of being used for.
Background technology
For the large-sized photovoltaic grid-connected system, for connecting line between less battery component and the inverter, and easy to maintenance in the future, generally, need between battery component and inverter, increase the photovoltaic array header box so that the input of the array of multichannel is converged into one tunnel output, make things convenient for the inverter wiring.At present common photovoltaic array header box is generally comparatively simple, only be that the multichannel array that will import converges into one tunnel output, usually the negative or positive electrode that does not insert fuse or only import at one road array inserts fuse, can't prevent that another negative pole or positive pole that does not insert fuse of array opens circuit here, thereby the damage whole system has reduced the reliability of system.
The utility model content
The utility model is at the deficiencies in the prior art, designed and developed out a kind ofly can make the safe and reliable photovoltaic array header box of grid-connected photovoltaic system.
The utility model is achieved through the following technical solutions:
A kind of photovoltaic array header box, anodal and the negative pole header box that inserts in parallel of the multichannel of photovoltaic array, then by the busbar parallel connection of confluxing, through positive pole after confluxing and negative pole multichannel array input parallel connection is one the tunnel, photovoltaic array each Lu Zhongjun anodal and negative pole installs a direct current fuse, photovoltaic array multichannel positive pole or multichannel negative pole all by DC fuse again parallel connection be one the tunnel.
A kind of photovoltaic array header box, described DC fuse is installed in the fuse holder, described photovoltaic array multichannel positive pole or multichannel negative pole all by fuse holder again parallel connection be one the tunnel.
A kind of photovoltaic array header box all connects lead-out terminal by circuit breaker after described photovoltaic array multichannel positive pole or the parallel connection of multichannel negative pole.
The utility model has all inserted withstand voltage fuse above 1KV with the positive pole and the negative pole of photovoltaic array input, this fuse is positioned in the fuse holder, can be according to using the different fuses that be changed different brackets, no matter be which utmost point effectively protection system that is short-circuited all; Insert circuit breaker in the output back of confluxing, circuit breaker can make things convenient for the user safeguarding or in emergency circumstances disconnecting being connected of photovoltaic array and inverter.Thereby guaranteed the safety of grid-connected photovoltaic system, and improved the reliability of system greatly.
