Abstract
The utility model provides a bypass protective module for a solar photovoltaic connecting box. The bypass protective module for the solar photovoltaic connecting box comprises a metal frame which is divided into a plurality of branch frames which are independent and arrayed at intervals. The surfaces of the branch frames are all provided with electric-conduction metal layers. Except for the branch frame at the first place, the electric-conduction metal layers of the rest branch frames are connected with patch diodes in a welded mode. Jumper wires are connected between the electric-conduction metal layers and the patch diodes of two adjacent branch frames. Epoxy resin plastic package layers are wrapped outside the branch frames, the patch diodes and the jumper wires. The bypass protective unit for the solar photovoltaic connecting box has the advantages of being free of mounting stress, convenient to assemble, manpower-saving and high in efficiency. The size is uniform so that cost of repeated investment is lowered. Due to the same power, packaging size is reduced, cost is lowered, mounting is easy, and the bypass protective module can be used with a high-power connecting box which is needed by an assembly in a matching mode.
Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly protection special module device that belongs to, and belongs to the solar energy power generating apparatus field.
Background technology
At present common photovoltaic terminal box comprises plastic casing, cap and bypass protection part, and general bypass protection partly adopts welding diode to the metallic conduction sheet or diode is stuck in the metal draw-in groove, is connected to and forms the loop on the metalwork.This structure can realize the effect of photovoltaic junction box, but has following problem: 1. diode adopts folder or secondary welding, can produce stress, and stamp-mounting-paper diode 2 causes secondary damage; 2. the diode heating mainly is that heat radiation is slow by encapsulation plastic packaging material and metal pins heat radiation.3. the installation dimension disunity causes versatility poor.4. diode and metalwork coupling part are limited by each technological level, cause poor stability.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of can avoid stamp-mounting-paper diode 2 damaged, a kind of photovoltaic terminal box bypass protection module that thermal diffusivity is good.
The utility model is realized by following measures:
A kind of photovoltaic terminal box bypass protection module of the present utility model; comprise metal framework; described metal framework is divided into some independences and spaced 4-7 minute framework; the framework surface was provided with conductive metal layer in described minute; all be welded with stamp-mounting-paper diode on the conductive metal layer of minute framework of other except framework is divided in the first place; be connected with wire jumper between conductive metal layer on adjacent two minutes frameworks and the stamp-mounting-paper diode, minute framework, stamp-mounting-paper diode and wire jumper are coated with epoxy resin plastic packaging layer.
Above-mentioned each minute framework upper end is provided with the welding position of extending epoxy resin plastic packaging layer, is provided with installing hole and the cable connecting hole that extends epoxy resin plastic packaging layer on minute framework of the first and position, end.
Between above-mentioned diode stamp-mounting-paper diode and the conductive metal layer substrate is set, described substrate is molybdenum sheet, copper sheet or sheffield plate.
The beneficial effects of the utility model are:

Fig. 2 is external structure schematic diagram of the present utility model.
Wherein: 1 minute framework, 2 stamp-mounting-paper diodes, 3 wire jumpers, 4 cable connecting holes, 5 installing holes, 6 welding positions, 7 epoxy resin plastic packaging layers.
Embodiment
As shown in Figure 1, 2; a kind of photovoltaic terminal box bypass protection module of the present utility model; comprise metal framework; metal framework is divided into some independences and spaced 4-7 minute framework 1; divide framework 1 surface to be provided with conductive metal layer; except framework 1 is divided in the first place other minute framework conductive metal layer on all be welded with stamp-mounting-paper diode 2; be connected with wire jumper 3 between conductive metal layer on adjacent two minutes frameworks 1 and the stamp-mounting-paper diode 2; divide framework 1, stamp-mounting-paper diode 2 and wire jumper 3 to be coated with epoxy resin plastic packaging layer 7, can play the effect of waterproof insulation.
Each divides framework 1 upper end to be provided with the welding position of extending epoxy resin plastic packaging layer 7, and be provided with installing hole and the cable connecting hole that extends epoxy resin plastic packaging layer 7 the first and dividing on the framework 1 of position, end.
Adopt stamp-mounting-paper diode 2, a pole-face of diode is contacted with metal framework fully, more be conducive to stamp-mounting-paper diode 2 heat transfers, be conducive to reduce installing space, realized the setting of different capacity in less space, overall dimension changes little.During use, directly be fixed to photovoltaic junction box inside by installing hole 5, cable is received on the cable connecting hole 4, busbar directly arrives each welding position 6.
Epoxy resin plastic packaging layer 7 can use mold injection, adopts high strength low-strees epoxy resin encapsulating layer, thereby reduces stress, has strengthened waterproof and dampproof property and withstand voltage properties.After adopting epoxy resin plastic packaging layer 7 to solidify, waterproof and dampproof property and withstand voltage properties have been strengthened.Solar junction box manufacturer is affixed to module on the photovoltaic junction box when mounted, will just can finish assembling on the cable welding, and size is unified, and outward appearance is beautiful, and radiating block also can be installed at epoxy resin plastic packaging layer by producer, strengthens heat radiation.
During use, the attached cable position connects respectively and connects respectively solar panel and charging control loop.Solar panel is subjected to produce electric energy behind the solar radiation, directly is transported to the charging control loop by connecting line; When a certain solar panel is blocked cisco unity malfunction, by stamp-mounting-paper diode 2 conductings, avoid occuring hot spot, burn cell panel, thereby protect this solar panel, and so that all the other solar panels work on.
Above-described embodiment is described to be to specify this patent; though describe by specific term in the literary composition; but can not limit with this protection range of this patent; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
