Abstract
The utility model discloses a but vortex -resistant's photovoltaic conflux case, the power distribution box comprises a box body, the rear side of box passes through fixing bolt and the support is fixed mutually, the bottom of box is equipped with two communication interface and a wire hole. The utility model discloses wire hole structure with convenient wiring replaces traditional scene 2 line pore structure, has optimized the wire hole mode of box structure, has both avoided the hidden danger that the vortex appears, has guaranteed the leakproofness of box again, the reduction of wire hole has simultaneously also reduced the water joint quantity, sparingly converges flow box manufacturing cost.
Description
Technical field
This utility model relates to the equipment of photovoltaic system application, particularly relate to a kind of can the photovoltaic combiner box of anti-eddy current.
Background technology
Along with country's support to Photovoltaic new energy, this several years photovoltaic products achieve quickly development recently, and the photovoltaic combiner box product supporting with it also obtains substantial amounts of use.
Presently commercially available photovoltaic combiner box is equipped with two wire holes, make a distinction between both positive and negative polarity, although this kind of mode is prone to differentiate, but have ignored the casing between both positive and negative polarity is irony, both positive and negative polarity round casing due to electric current change over time, electromagnetic induction produces faradic current and causes eddy current to produce heat, as found to solve this problem not in time, header box may burn the internal electric elements of header box due to the appearance of eddy current, Photovoltaic new energy system is damaged, thus causes a large amount of economic losses of client.It addition, the outer package of two core cable need to be broken wiring when by two wire holes, being respectively connected in header box, this proposes requirement to the sealing property of header box, adds the probability broken down simultaneously.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, it is provided that a kind of can the photovoltaic combiner box of anti-eddy current.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of can the photovoltaic combiner box of anti-eddy current, including casing, the rear side of described casing is fixed by fixing bolt and support, and the bottom of described casing is provided with two communication interfaces and a wire hole.
Further, the front side of described casing is provided with case lid, and the side of case lid is connected with body pivot, and opposite side is fixed with casing by clamping close device or separates.
Further, the diameter of described wire hole is slightly less than the twice value of common two core cable diameter, it is simple to outlet and wiring.
Further, described wire hole is provided with waterproof sealing coil, waterproof and good sealing effect.
This utility model photovoltaic combiner box can prevent the generation of eddy current, solves the vortex phenomenon produced because of galvanomagnetic-effect at different wire holes in photovoltaic combiner box due to outlet；Realize the protection to header box equipment in the collection of photovoltaic electric energy of Photovoltaic new energy system user, it is achieved protection electrical equipment and system run safety, it is achieved more efficient operation and management.
The beneficial effects of the utility model are:
1, substitute two traditional wire hole structures by a convenient for wiring wire hole structure, optimize the wire hole mode of body structure, both avoided the hidden danger that eddy current occurs, in turn ensure that the sealing of casing.
2, the minimizing of wire hole simultaneously also reduces water joint consumption, saves header box production cost.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is right view of the present utility model；
Fig. 3 is upward view of the present utility model.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, this utility model is described in detail.
Described in the present embodiment can the photovoltaic combiner box of anti-eddy current, as shown in Figures 1 to 3, including casing 1, the rear side of casing 1 is fixed by fixing bolt 4 and support 3, front side is provided with case lid, and the side of case lid is rotationally connected with casing 1, and opposite side is fixing with casing 1 by clamping close device 2 or separates；The bottom of casing 1 is provided with two communication interfaces 5 and a wire hole 6, is provided with waterproof sealing coil 7 in wire hole 6, and the diameter of wire hole 6 is slightly less than the twice value of common two core cable diameter.
The present embodiment substitutes two traditional wire hole structures by a convenient for wiring wire hole structure, optimize the wire hole mode of casing 1 structure, both the hidden danger that eddy current occurs had been avoided, in turn ensure that the sealing of casing 1, the minimizing of wire hole simultaneously also reduces water joint consumption, saves header box production cost.
