Figure 13 is the signal of the structure for the photovoltaic power generation system 100 for representing the anti-backflow device 1 using present embodiment
Figure.Photovoltaic power generation system 100 possesses solar cell 200 and battery 300 and anti-backflow device 1.Solar cell 200 connects
Take over control the input terminal 11 of backflow device 1.Battery 300 connects the lead-out terminal 12 of anti-backflow device 1.In addition, by above-mentioned
Anti-backflow device 1 structure, as shown in figure 13, form connection input terminal 11 and lead-out terminal 12 circuit 15.
In the circuit 15, diode 8 is configured between input terminal 11 and lead-out terminal 12.Diode 8 is allowed from input
Flowing of the terminal 11 to the electric current of lead-out terminal 12, limit the flowing to the electric current of input terminal 11 from lead-out terminal 12.Input

Figure 14 is the time diagram for representing the action of anti-backflow device 1 in photovoltaic power generation system 100.Figure 14 (A) represents anti-
The change of the current value flowed through in backflow device 1.Figure 14 (B) represents the change of the state of contact mechanism part 4 in anti-backflow device 1
Change.
In photovoltaic power generation system 100, solar cell 200 generates electricity, then electric current flows to coil 51 by input terminal 11.
Sunshine is weak, when the current value flowed through in coil 51 is less than defined action threshold value I_th1 (for example, 3A) (from moment t0 then
Carve t1), electromagnet group 5 will not excitation.Therefore, contact mechanism part 4 maintains off state (OFF).Therefore, from solar cell
The electric current of 200 supplies is charged by diode 8 to battery 300.In addition, the generated energy of solar cell 200 is small, battery
In the case that 300 voltage exceedes the voltage of solar cell 200, it is possible to carried out from battery 300 to solar cell 200
Electric current adverse current, still, because contact mechanism part 4 is in off state, the adverse current of electric current can be prevented by diode 8.Thus,
It can prevent from flowing into reverse current in solar cell 200, the damage of solar cell 200 can be prevented.
On the other hand, sun light intensity, the current value flowed through in coil 51 is in action more than threshold value I_th1 (moment t1), then
The excitation of electromagnet group 5, contact mechanism part 4 switch to connection status (ON) from off state (OFF).Therefore, from solar cell
The electric current of 200 supplies, around diode 8, is charged by the few contact mechanism part 4 of resistance value to battery 300.Therefore, the sun
Can battery 200 generated energy it is big in the case of, do not flow through high current in diode 8.Therefore, it is possible to suppress in diode 8
The generation of the problem of damage of energy loss or diode 8 etc..
The current value flowed through in coil 51 (moment t1 to moment t2), contact in defined more than reset threshold I_th2
Mechanism part 4 maintains connection status (ON).Then, when current value is less than reset threshold I-th2 (moment t2), contact mechanism part 4
Off state (OFF) is switched to from connection status (ON).
As described above, the anti-backflow device 1 of present embodiment, due to short between the panel of ground connection or solar cell 200

It is connected by substrate with circuit 15, can also passes through the movement of these rib limiting fuses 9.Particularly, first can be passed through
The movement of the horizontal support rib 305 of horizontal support rib 304 and second and the limiting fuses 9 of the 3rd horizontal support rib 306 in transverse direction.In addition,
By first time fuse ribs 203 and second time fuse ribs 204 can limiting fuses 9 above-below direction shifting
It is dynamic.
Terminal board 3 has on the first of support connection member 10 ribs 308 in ribs 307 and second.In addition, pedestal
2 have first time ribs 205 and second time ribs 206.Therefore, in the inside of terminal board 3, can be suppressed by these ribs
Shake of the connection member 10 in above-below direction.Particularly, such as present embodiment, intersected due to connection member 10 with fuse 9 and matched somebody with somebody
Put, even if the length of connection member 10 becomes big, also can by suppress connection member 10 wave suppress with terminal board 3
The contact of other parts.
One embodiment of the present invention is this concludes the description of, but the invention is not restricted to above-mentioned embodiment, is not departing from hair
Various changes can be carried out in the range of bright purport.
