Abstract
The utility model relates to a bypass protector for a solar photovoltaic junction box. The protector comprises a metal frame which is divided into a plurality of sub-frames which are independent and arranged at intervals. Conductive metal layers are arranged on the surfaces of the sub-frames. Electrode surfaces of surface-mounted diodes are welded on the conductive metal layers of the sub-frames except for a first sub-frame. Jumpers are connected between the conductive metal layers on adjacent sub-frames and other electrode surfaces of the surface-mounted diodes. Welding positions are arranged at the upper ends of the sub-frames, and installation holes and cable connection holes are arranged in the first and last sub-frames. The bypass protector for the solar photovoltaic junction box has the advantages that the installation stress does not exist, the assembly is convenient, labors are saved, and the efficiency is high; sizes are unified, and repeated input costs are reduced; and power is identical, so that the packaging size can be reduced, the cost is reduced, the installation is facilitated, and the protector can be matched with large-power junction boxes needed by components to be used.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box bypass protector, belongs to the solar energy power generating apparatus field.
Background technology
Common photovoltaic terminal box comprises plastic casing, cap and bypass protection part at present; general bypass protection partly adopts diode directly pin to be welded on 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 diode 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 the stamp-mounting-paper diode damaged, a kind of photovoltaic terminal box bypass protector that thermal diffusivity is good.
The utility model is realized by following measures:
A kind of photovoltaic terminal box bypass protector of the present utility model; comprise metal framework; described metal framework is divided into some independences and spaced minute framework; the framework surface was provided with conductive metal layer in described minute; all be welded with an electrode surface of 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 another electrode surface of stamp-mounting-paper diode; each divides the framework upper end to be provided with welding position, is provided with installing hole and cable connecting hole on the first and last minute framework.
Above-mentioned metal framework is divided into 4-7 minute framework.
Between above-mentioned 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:
1, without stress is installed, easy to assembly, to save manually, efficient is high;
2, size is unified, reduces the overlapping investment cost;
3, equal-wattage can reduce package dimension, reduces cost, be easy to install, but the high-power terminal box that matable assembly needs is used.
Description of drawings
Fig. 1 is structural representation 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.
Embodiment
As shown in Figure 1; a kind of photovoltaic terminal box of the utility model bypass protector; 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; other minute except framework 1 is divided in the first place all is welded with an electrode surface of stamp-mounting-paper diode 2 on framework 1 the conductive metal layer; be connected with wire jumper 3 between conductive metal layer on adjacent two minutes frameworks 1 and another electrode surface of stamp-mounting-paper diode 2; each divides framework 1 upper end to be provided with welding position 6, and be provided with installing hole 5 and cable connecting hole 4 the first and dividing on the framework 1 of position, end.
Adopt stamp-mounting-paper diode 2, 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.
Between stamp-mounting-paper diode 2 and the conductive metal layer substrate is set.Substrate can adopt molybdenum sheet, copper sheet or sheffield plate, eliminates welding stress, can adopt the hot reflux welding manner.
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.
