Description
Technical field
The utility model belongs to technical field of new energies, relates to a kind of photovoltaic combiner box, specifically a kind of assembly type height protection photovoltaic combiner box.
Background technology
Universal along with the theory such as new forms of energy, low-carbon (LC), solar energy generation technology flourish, as its upstream equipment---photovoltaic combiner box obtains and uses widely, causes its quantity rapid growth.Photovoltaic combiner box all adopts welded type in the market.Theoretically, welded type is originally also given no cause for much criticism, single from degree of protection requirement, as long as carry out full weld to whole casing, also should can reach corresponding degree of protection, but actual conditions is not really like this.Reason has following 3 points:
One, weld seam is long, and welding job amount is large.For the header box on 16 tunnels, its body fusion length is about 2 meters, adds hangers, mounting panel back nut, and seam overall length is at about 2.5 meters.Because the wooden partition of casing is thinner, be generally no more than 1.5 millimeters.Carry out full weld operation under such conditions, difficulty is well imagined.
Even if two complete above welding reluctantly, the box deformation that thing followed thermal stress, thermal deformation afterwards causes, door-plate is poorly sealed, and weld seam can not adapt to the test of harsh and unforgiving environments, and under degree of protection, degradation problem also brings inconvenience for equipment in operation and maintenance from now on.For solving the problem, makers' common practice is that to change full weld be the spot welding having certain distance, does not weld part only by putting postwelding plastic-blasting to cover protection question.This kind of way also only " is deceived oneself " interim measure of curing the symptoms, not the disease of formula.Product is after long-distance transport, if solder joint sealing-off, tank surface relates to plastic-blasting again, and scene cannot well be remedied.
Three, weld job itself is special work post, has certain harm to human body, and for the product that consumption is very large, too much welding design itself is also a kind of not enough.In header box manufacture course of products, punching press, bending are absolutely necessary two procedures.If add welding, just people is for adding a procedure again, and too much human factor is unfavorable for the stable of product quality, and production cost sharply raises simultaneously, is unfavorable for market competition.
In sum, along with " fieriness " increasingly of market competition, be badly in need of a kind of can be able to reducing costs, product quality is relatively stable again, is applicable to again the photovoltaic combiner box produced in enormous quantities.
