The caution device comprises a first solar battery pack, wherein the first solar battery pack comprises at least two solar battery pieces which are connected in series in the same direction. The caution device has the characteristics that a first diode group and a first indicating lamp are connected in parallel at two ends of the first solar battery pack, and the first diode group consists of a first diode and a second diode which are connected in parallel. The anode and the cathode of the first diode group are respectively connected with the cathode and the anode of the first solar battery pack. The caution device can be used for preventing the solar panel from short circuit.
Description
Technical field
The present invention relates to a kind of solar cell.Specifically, be the alarming device that is used for preventing the solar panel short circuit.
Background technology
All know in the manufacture of solar cells industry, at present, only be provided with solar battery group on the solar panel, this solar battery group has the multi-disc solar battery sheet to be series aiding connection to form.Solar battery group in use meets leaf or cloud covers, just can't normal power generation.Owing to internal resistance is arranged in the solar battery sheet, when being covered by leaf or cloud, heating easily makes that electric battery is prone to burnt out.
Summary of the invention
The problem that the present invention will solve provides a kind of solar panel short circuit alarming device.Adopt this solar panel short circuit alarming device, the situation that can avoid electric battery to burn out takes place, and makes that solar battery group can't operate as normal.
For addressing the above problem, take following technical scheme:
Solar panel short circuit alarming device of the present invention comprises first solar battery group, and this first solar battery group has at least two solar battery sheets to be series aiding connection to form.Its design feature is that the two ends of said first solar battery group are parallel with the first diode group and first pilot lamp, and the said first diode group is formed in parallel by first diode and second diode.The positive pole of the said first diode group links to each other with anodal with the negative pole of first solar battery group respectively with negative pole.
Further improvement project of the present invention is, comprises second solar battery group, and the two ends of second solar battery group are parallel with the second diode group and second pilot lamp.The said second diode group is formed in parallel by the 3rd diode and the 4th diode.The positive pole of the said second diode group links to each other with anodal with the negative pole of second solar battery group respectively with negative pole.The positive pole of the first diode group links to each other with the negative pole of the second diode group.
Further improvement project of the present invention is, comprises the 3rd solar battery group, and the two ends of the 3rd solar battery group are parallel with the 3rd diode group and the 3rd pilot lamp.Said the 3rd diode group is formed in parallel by the 5th diode and the 6th diode; The positive pole of said the 3rd diode group links to each other with anodal with the negative pole of the 3rd solar battery group respectively with negative pole.All link to each other between the positive pole of the second diode group and the 3rd diode cathode.
Take such scheme, have the following advantages:
Can find out that by such scheme owing to be parallel with diode group and pilot lamp at the two ends of said solar battery group, said diode group is formed in parallel by two diodes.And the positive pole of said diode links to each other with anodal with the negative pole of solar battery group respectively with negative pole.Under normal operation, the electric current of solar battery group flows to anodal from negative pole, flow through the pilot lamp as load.Because diode has unidirectional conduction, is equivalent to open circuit, so the pilot lamp operate as normal.As when leaf or cloud occurring and covering, diode is then breakdown, is equivalent to lead, and pilot lamp and electric battery are by short circuit, and this moment, pilot lamp did not work.This moment, the staff can whether operate as normal judges whether solar battery group exists hot spot effect or reverse current recoil through pilot lamp.Thereby the situation of having avoided solar battery group to be burnt out takes place, and has guaranteed that solar battery group can operate as normal.
