Description
Technical field
The utility model relates to a kind of solar assembly junction box with fault cues function.
Background technology
Widely used terminal box and diode and terminal box body connected mode mainly contain two kinds in the market: welded type and plug-in type, by welding diode or to be plugged in junction box body in metal frame, its shortcoming is: be difficult to detect that problem has appearred in which diode, even if the problem which diode has occurred detected, unless original diode is destroyed, otherwise cannot change, be difficult to when assembly diode goes wrong change fast, for the diode changed in assembly brings very large inconvenience, and diode adds that the volume of pin makes terminal box bulk volume larger, affect the heat radiation of terminal box.
Therefore, in order to make the radiating effect of terminal box better, diode more easily detects and is replaced when occurring abnormal, and solar components industry in the urgent need to a small volume, radiating effect better and can detect the terminal box whether diode normally work at any time and support the use with it.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of solar assembly junction box with fault cues function.
Solve the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of solar assembly junction box with fault cues function, it is characterized in that: described solar assembly junction box comprises terminal block housings, this terminal block housings is provided with cathode output end, the binding post of cathode output end and two groups or more, each group binding post include one for connect solar cell string positive pole positive terminal with one for being connected the negative terminal of solar cell string negative pole, the positive terminal of first group of binding post is electrically connected with described cathode output end, the negative terminal of last group binding post is electrically connected with described cathode output end, and, the negative terminal of last group of binding post is electrically connected with the positive terminal of rear one group of binding post, a bypass diode and a light emitting diode is all serially connected with between the positive terminal of each group binding post described and negative terminal, the negative electrode of wherein said bypass diode is electrically connected with the anode of light emitting diode, the anode of bypass diode is electrically connected with negative terminal, and the negative electrode of light emitting diode is electrically connected with positive terminal.
For the ease of observing, the one new as the utility model is improved, and described terminal block housings has the through hole for exposing described light emitting diode.
Improve as one of the present utility model, described bypass diode is modular diode.
Compared with prior art, the utility model has following beneficial effect:
First, the utility model is provided with bypass diode and light emitting diode, judge whether the solar components connecting this solar assembly junction box breaks down by whether light emitting diode is luminous, and can find out by light emitting diode the solar cell string broken down;
Second, bypass diode of the present utility model adopts the modular diode with pin, thus be easier to carry out changing, obtaining better heat dispersion, and, because modular diode has less volume compared to plug-in type diode, therefore the terminal block housings volume of this solar assembly junction box can diminish, thus effectively improves the integral heat sink effect of this solar assembly junction box;
In sum, the utility model has to be easy to whether detection solar components normally works, bypass diode changes the advantage easy, volume is little, radiating efficiency is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the circuit theory diagrams of solar assembly junction box of the present utility model.
Detailed description of the invention
As shown in Figure 1, the solar assembly junction box with fault cues function of the present utility model, comprise terminal block housings 1, this terminal block housings 1 is provided with cathode output end V+, the binding post of cathode output end V-and two group or more, each group binding post includes one for connecting the positive terminal S1+ of solar cell string positive pole, S2+, Sn+ with one for being connected the negative terminal S1-of solar cell string negative pole, S2-, Sn-, the positive terminal S1+ of first group of binding post is electrically connected with cathode output end V+, the negative terminal Sn-of last group binding post is electrically connected with cathode output end V-, and, the negative terminal of last group of binding post is electrically connected with positive terminal such as S1-and the S2+ of rear one group of binding post, the positive terminal of each group binding post is if Sn+ and negative terminal are as being all serially connected with an a bypass diode D1 and light emitting diode D2 between Sn-, this bypass diode D1 is the modular diode with pin, wherein the negative electrode of bypass diode D1 is electrically connected with the anode of light emitting diode D2, the anode of bypass diode D1 with negative terminal as Sn-is electrically connected, the negative electrode of light emitting diode D2 with positive terminal as Sn+ is electrically connected.In addition, terminal block housings 1 has the through hole for exposing light emitting diode D2, so that observe.
The operation principle with the solar assembly junction box of fault cues function of the present utility model is as follows:
Solar assembly junction box of the present utility model, its each group binding post all can connect two solar cell strings, the positive pole of one of them solar cell string connects the positive terminal of this group binding post, negative pole is electrically connected with the positive pole of another solar cell string, the negative pole of another solar cell string connects the negative terminal of this group binding post, thus each solar cell was ganged up this solar assembly junction box and is composed in series solar components.
When solar components normally works, according to diode forward conducting, oppositely by characteristic, each bypass diode D1 is not activated work, electric current is not had to flow through yet, the light emitting diode D2 connected with it is non-luminous, so just can judge that assembly is not abnormal by the not luminous of light emitting diode D2, bypass diode D1 is not activated work.
When there is abnormal (such as hot plate effect) in solar components, according to diode forward conducting, oppositely by characteristic, the bypass diode D1 that the solar cell string broken down connects starts to start work, also electric current is had to flow through, at this moment the light emitting diode D2 connected with it is luminous, so just can judge that assembly has abnormal (or hot spot effect occurs), in bypass diode D1 startup work by the luminescence of light emitting diode D2.
When solar components normally works, according to diode forward conducting, oppositely by characteristic, each bypass diode D1 is not activated work, electric current is not had to flow through yet, the light emitting diode D2 connected with it is non-luminous, but it is also likely itself break down to cause open circuit that bypass diode D1 is not activated work, at this moment light emitting diode D2 is also non-luminous, we just do not judge that whether bypass diode D1 is still intact, at this moment, we are just by artificially manufacturing hot spot effect (such as covering a slice or several cell pieces with object), bypass diode D1 is made to start work, if at this moment light emitting diode D2 does not still light, be bypass diode D1 open circuit with regard to explanation and cannot play a protective role, because we use the modular diode holding easily changeable band pin, so just can change diode very easily, so normally work at assembly, time diode breaks down, we also judge out by whether luminous light emitting diode D2 is next.
The utility model does not limit to and above-mentioned detailed description of the invention; according to foregoing; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; the utility model can also make the equivalent modifications of other various ways, replacement or change, all drops among protection domain of the present utility model.
