In solar photovoltaic generation system, header box has another name called the photovoltaic header box, the solar energy header box, photovoltaic lightning protection header box etc., the reliability and the practicality that are used for the raising system, usually by photovoltaic special DC lightning-protection module, dc fuse and circuit breaker etc. connect to form, as shown in Figure 1, dc fuse 101 array respectively is fixed as, two arrange down, every row's dc fuse 101 tops are respectively equipped with a copper bar 102, on, arranging dc fuse 101 down is parallel on the described copper bar 102 through the outlet of its upper end respectively, photovoltaic header box below is provided with incoming line, the both positive and negative polarity inlet wire is received respectively, arrange the lower end of dc fuse 101 down, on, under arrange dc fuse 101 and conflux in copper bar 102, insert on the circuit breakers 103 through copper bar 102.
As mentioned above, there is following some deficiency in the layout of each electric elements in the photovoltaic header box of the prior art:
1. it is bigger to take up room, Internal cable copper bar large usage quantity, and cost increases;
2. upper and lower two row's dc fuse spacings are little, make troubles to wiring;
3. layout, cabling are not attractive in appearance.
Summary of the invention
The object of the invention provides a kind of photovoltaic lightning protection header box, by the improvement to topology layout, makes wiring operation more convenient, and cabling is more attractive in appearance, has reduced can save the copper bar consumption simultaneously to the taking of space, and has reduced cost.
For achieving the above object, the technical solution used in the present invention is: a kind of photovoltaic lightning protection header box, comprise a casing, be arranged at the circuit breaker in this casing, lightning protection device, and the fuse assembly that connects the positive and negative level of described circuit breaker two ends, described fuse assembly is made of 2 groups of anodal fuse subregions and 2 groups of negative pole fuse subregions, each group just, negative pole fuse subregion is arranged in the both sides of described circuit breaker, described circuit breaker just, negative input end is drawn by copper bar respectively and is extended to both sides fuse subregion, 2 groups of fuse subregions of homonymy are distributed in corresponding copper bar both sides, each organizes the output of fuse subregion all near corresponding described copper bar setting, and is electrically connected through lead and described copper bar.
In the technique scheme, each organizes described anodal fuse subregion and negative pole fuse subregion respectively by a plurality of dc fuses and connect and constitute the corresponding one tunnel described circuit breaker input of each dc fuse.
In the technique scheme, each output of organizing described anodal fuse subregion and negative pole fuse subregion is connected with described copper bar through copper strips respectively.
In the technique scheme, the input of described circuit breaker is positioned at both sides, described casing below, is respectively the positive and negative electrode incoming line, and incoming line is connected with corresponding fuse subregion output through described copper bar; Be provided with the circuit breaker output between the described positive and negative electrode incoming line, constituted by positive and negative line outlet.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1, since among the present invention 2 groups of positive and negative electrode fuse subregions be arranged in the both sides of circuit breaker respectively, 2 groups of fuse subregions of homonymy are distributed in corresponding copper bar both sides, and one group of positive and negative electrode fuse subregion only are set in the past, and the fuse subregion only is distributed in the structure of copper bar one side and compares, before the use amount of copper bar only needs half, saved the use amount of copper bar greatly, reduced cost, simultaneously, be symmetrically distributed, taking of inner space is littler, and wiring is convenient, and cabling is more attractive in appearance;
2, the both sides of copper bar are provided with a plurality of copper strips corresponding with dc fuse among the present invention, the output of each group positive and negative electrode fuse subregion links to each other with described copper bar through copper strips respectively, compared with being connected with copper bar with electric wire in the past, the use of circuit is few, wiring easy and simple to handle, wiring is more quick and easy;
3, the present invention is simple in structure, is easy to realize.
