Abstract
The utility model provides a novel photovoltaic junction box which comprises a box body, wherein the box body is internally provided with a plurality of parallel wire holders, every two adjoining wire holders are electrically connected with each other by a bypass diode, output ends of the wire holders, which are near to the two sides of the box body, are respectively and electrically connected with an anode output cable and a cathode output cable at one side of the box body, the box body is internally provided with a fault detecting chip which is used for detecting whether a solar battery component is abnormal or not, and two wiring terminals at two ends of the fault detecting chip are respectively fixed on the output ends of the wire holders, which are near to the two sides of the box body. The novel photovoltaic junction box has the benefit effects that the box body is internally provided with the fault detecting chip which is used for detecting whether the solar battery component is abnormal or not, so that a specific position can be fast discovered and positioned, and a fault reason can be analyzed once the solar battery component is faulted, therefore, the solar battery component can be fast overhauled, and the generating capacity of a system can be improved; and 24-hour anti-stealing and protective monitoring is offered, so that the novel photovoltaic junction box can be well monitored at night, and the losing or stealing position can be exactly discovered.
Description
(1) technical field
Whether unusual the utility model relates to a kind of terminal box, relate in particular to a kind ofly can detect solar module novel photovoltaic junction box.
(2) background technology
Photovoltaic junction box is a kind of being installed on the solar panel, a kind of transition apparatus that battery component on solar panel lead-in wire is coupled together, inside generally is provided with a plurality of bypass diodes, and this bypass diode is used to prevent that reverse charging from damaging the battery component on the solar panel and prevent that the battery component short circuit from causing the entire cell assembly to use.The failure detector that does not have the special detection solar module in this photovoltaic junction box, if solar module has damage, can bring very big energy loss to solar power system, take time and effort by hand inspection, can not satisfy system's requirement of maintenance fast, bring very big trouble for the operation maintenance in large solar power station.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provide a kind of simple in structure, easy to use, can detect solar module and whether have unusual novel photovoltaic junction box.
The technical scheme in the invention for solving the technical problem is: a kind of novel photovoltaic junction box, comprise box body, be provided with a plurality of junction blocks arranged side by side in this box body, electrically connect by bypass diode between adjacent two described junction blocks, near the output of the described junction block of described box body both sides respectively with just be positioned at described box body one side, the negative pole output cable electrically connects, whether unusual be provided with in the described box body and detect solar module fault detect chip, the binding post at these fault detect chip two ends is separately fixed on the output near the described junction block of described box body both sides.
Further, described box body is provided with draw-in groove, and described fault detect chip places in this draw-in groove.
Further, the end of the binding post of described fault detect chip is provided with fixing hole.
The utility model in use, the fault detect chip is determined that solar module is that part of and is broken down by detecting voltage, electric current and variation of temperature value on junction block and the bypass diode, and can judge failure cause, thus can overhaul rapidly, improve system's energy output; And the monitoring of 24 hours anti-theft protections is provided, and make well be monitored night, can accurately find out and lose or steal the position.Because box body is provided with draw-in groove, the fault detect chip places in this draw-in groove, makes things convenient for the fixing of fault detect chip.The end of the binding post of fault detect chip is provided with fixing hole, and screw passes this fixing hole and is screwed onto on the output of junction block, reaches fixing the fault detect chip.
Whether unusual the beneficial effects of the utility model are: detect solar module fault detect chip owing to be provided with in the box body of the present utility model, make solar module can find rapidly once breaking down, locate particular location rapidly and analyze failure cause, thereby can overhaul rapidly, improve system's energy output.And the monitoring of 24 hours anti-theft protections is provided, and make well be monitored night, can accurately find out and lose or steal the position.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of novel photovoltaic junction box, comprise box body 1, be provided with a plurality of junction blocks arranged side by side 2 in this box body 1, electrically connect by bypass diode 3 between adjacent two described junction blocks 2, near the output of the described junction block 2 of described box body 1 both sides respectively with just be positioned at described box body 1 one sides, negative pole output cable 4,5 electrically connect, be provided with in the described box body 1 and detect the whether unusual fault detect chip 6 of solar module, described box body 1 is provided with draw-in groove 7, described fault detect chip 6 places in this draw-in groove 7, the binding post at described fault detect chip 6 two ends is separately fixed on the output near the described junction block 2 of described box body 1 both sides, the end of the binding post of described fault detect chip 6 is provided with fixing hole, screw 8 passes this fixing hole and is screwed onto on the output of junction block 2, reaches fixing fault detect chip 6.
The utility model in use, fault detect chip 6 is determined that solar module is that part of and is broken down by detecting voltage, electric current and variation of temperature value on junction block 2 and the bypass diode 3, and can judge failure cause, thus can overhaul rapidly, improve system's energy output; And the monitoring of 24 hours anti-theft protections is provided, and make well be monitored night, can accurately find out and lose or steal the position.
