Abstract
The invention relates to a divided type photovoltaic direct-current header box which comprises a countercurrent prevention diode chamber, a thermal insulation chamber and a direct-current convergence chamber. The thermal insulation chamber is fixed at the bottom end of the countercurrent prevention diode chamber, and the direct-current convergence chamber is fixed at the bottom end of the thermal insulation chamber. Fixing seats are all fixedly arranged on the left side and the right side of the upper end portion of the rear wall face of the countercurrent prevention diode chamber and the left side and the right side of the lower end portion of the rear wall face of the direct-current convergence chamber. The fixing seats are provided with fixing holes. The divided type photovoltaic direct-current header box completely solves the problem that the heat of a countercurrent prevention diode is conducted to a direct-current convergence component in the working process and has the advantages of being simple and compact in structure, safe, reliable and the like.
Description
Technical field
The present invention relates to a kind of photovoltaic DC header box, especially a kind of cellular-type photovoltaic DC header box.
Background technology
In order to reduce the connecting line between solar photovoltaic assembly array and other DC load or inverter, and maintenance and easy to maintenance, generally need between photovoltaic module and other DC load or inverter, increase header box, conflux Cheng Yilu output of the multi-channel DC in photovoltaic module, the wiring of convenient and DC load or inverter.
Usually in header box, the counnter attack diode can be installed, one of effect of counnter attack diode is to prevent that solar module or square formation be not when generating electricity, the electric current of storage battery send to assembly or square formation conversely, consumed energy not only, and can make assembly or square formation heating even damage; Two of effect is in battery array, prevents that the electric current between each branch road of square formation from sending.This is because the output voltage of each branch road of series connection can not definitely equate, each branch voltage always has the poor of height, perhaps a certain branch trouble, shade the output voltage that makes this branch road such as cover and reduce, the electric current of high voltage branch road will flow to the low-voltage branch road, even can make the reduction of the overall output voltage of square formation.
At present, the common photovoltaic counnter attack direct current conflux case components and parts that usually counnter attack diode and direct current confluxed are arranged in a casing, have following problem:
Counnter attack diode caloric value when work is very big, the box house temperature is raise, and direct current confluxes, components and parts have certain working temperature requirement, when the box house excess Temperature, the performance and used life of components and parts reduces greatly, very easily break down, even affect whole photovoltaic power station power generation efficiency.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of cellular-type photovoltaic DC header box of safe and reliable, the performance and used life that can extend components and parts is provided.
According to technical scheme provided by the invention, described cellular-type photovoltaic DC header box, it comprises counnter attack diode chamber, heat-insulating room and the direct current chamber of confluxing, bottom in counnter attack diode chamber is fixed with heat-insulating room, be fixed with the direct current chamber of confluxing in the bottom of heat-insulating room, all be fixed with holder in the left and right sides, rear surface upper end of counnter attack diode chamber and in the conflux left and right sides, rear surface bottom of chamber of direct current, be provided with fixing hole on holder.
Described heat-insulating room adopts air heat insulation or is filled with heat-barrier material.
The present invention thoroughly solved the counnter attack diode at work heat to the direct current components and parts conducting problem that confluxes, there is the advantages such as simple in structure, compact, safe and reliable.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is left view of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This cellular-type photovoltaic DC header box, it comprises counnter attack diode chamber 1, heat-insulating room 2 and the direct current chamber 3 of confluxing, the interior installation counnter attack diode (led) module in counnter attack diode chamber 1 and radiator, the direct currents needed components and parts that conflux are installed in conflux chamber 3 of direct current, bottom in counnter attack diode chamber 1 is fixed with heat-insulating room 2, be fixed with the direct current chamber 3 of confluxing in the bottom of heat-insulating room 2, all be fixed with holder 4 in the left and right sides, rear surface upper end of counnter attack diode chamber 1 and in the conflux left and right sides, rear surface bottom of chamber 3 of direct current, be provided with fixing hole 5 on holder 4, the direct current components and parts that conflux pass heat-insulating room 2 by electric wire and are connected with the counnter attack diode.
Described heat-insulating room 2 adopts air heat insulations or is filled with heat-barrier material, and the heat that stops counnter attack diode chamber 1 is to direct current chamber 3 conduction of confluxing.
The present invention by counnter attack diode and other direct current conflux two that components and parts separate at same casing indoor, middle by the conduction of heat-insulating room 2 physical isolation heats.
After cellular-type photovoltaic DC header box of the present invention is fixedly mounted on body of wall by holder 4, between the rear surface of photovoltaic DC header box and metope, from a distance, the heat that also can accelerate counnter attack diode chamber 1 distributes in air.
Claims (2)
