The metal-cored bad connection with joint of aging, cable inner all can cause the uncontrollable sensing high voltage of generation, form thunderbolt
The monkey wrench of surge impact.
In production application, also frequently there is the photovoltaic electrification component bypass protection module produced under any of the above factor
Internal by-pass protects the inefficacy of diode, and the first diode occurring in series diode negative pole end is all concentrated in inefficacy.Lost efficacy
The analysis result of diode also complies with the pattern of lightning surge impact failure and occurs in that chip scorification point at chip internal.
Utility model content
The purpose of this utility model be to provide a kind of be avoided that lightning surge signal to the damage of bypass diode thus
Bypass diode is caused to lose efficacy and simple in construction, dependable performance, low cost, photovoltaic electrification component bypass protection mould elegant in appearance
Block.
The technical solution of the utility model is: include photovoltaic power generation plate and bypass protection module, described bypass protection module
Include the bypass diode of some mutual concatenations, be parallel with lightning surge protector with described some bypass diodes concatenated
Part.
The polarity of described lightning surge protective device is consistent with the polarity of described bypass diode.
Described lightning surge protective device is Transient Suppression Diode or solid discharge diode.
Described lightning surge protective device is one, is connected in parallel on first front end and of the bypass diode of some concatenations
The rear end of latter one.
Described lightning surge protective device is equal, the most also with the bypass diode quantity of described some concatenations
Connect.
This utility model is when receiving the impact of lightning surge signal, and bypass diode and lightning surge protection device are led simultaneously
Logical, lightning surge protection device is connected to one stable voltage of bypass diode two ends output, forms voltage-stabilizing protection, it is to avoid
The high-voltage great-current impact to bypass protection diode, makes photovoltaic power generation plate be shorted, affects normal power generation, cause serious commercial
Loss.

Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model first embodiment,
Fig. 2 is the structural representation of this utility model the second embodiment；
In figure, 1 is photovoltaic power generation plate, and 2 is bypass protection module, and 3 is bypass diode, and 4 is lightning surge protective device.
Detailed description of the invention
Below in conjunction with the accompanying drawings two kinds of embodiments of the present utility model are elaborated.
Fig. 1 is the first embodiment of the present utility model, and photovoltaic electrification component protection module includes photovoltaic power generation plate 1 He
Bypass protection module 2, described bypass protection module includes the bypass diode 3 of some mutual concatenations, some concatenates with described
Bypass diode be parallel with lightning surge protective device 4, the polarity of described lightning surge protective device and described bypass two pole
The polarity of pipe is consistent, and described lightning surge protective device is Transient Suppression Diode or solid discharge diode, described thunderbolt wave
Gushing protective device is one, and the mode of employing Reflow Soldering is connected in parallel on first front end of the bypass diode of some concatenations with last
The rear end of one；After described lightning surge is protected device and connected, described bypass diode and described lightning surge protection device are same
Time conducting, lightning surge protection device be connected to bypass diode two ends output one stable voltage, formed voltage-stabilizing protection.Thunder
When hitting surging signal generation, described lightning surge protector is stable for the lightning surge of the high-voltage great-current range of set value at it
In, make photovoltaic electrification component normally can work under rated operational voltage, it is to avoid high-voltage great-current is to described bypass protection two pole
The impact of pipe, causes protected assembly to be shorted, affects normal power generation, cause serious financial consequences.
Fig. 2 is the second embodiment of the present utility model, and photovoltaic electrification component protection module includes photovoltaic power generation plate 1 He
Bypass protection module 2, described bypass protection module includes the bypass diode 3 of some mutual concatenations, in order to enhanced protection is imitated
Really, it is parallel with lightning surge protective device 4, the pole of described lightning surge protective device with described some bypass diodes concatenated
Property is consistent with the polarity of described bypass diode, and described lightning surge protective device is Transient Suppression Diode or solid discharge two
Pole is managed, and described lightning surge protective device is equal with the bypass diode quantity of described some concatenations, correspondingly and connect；Institute
After stating lightning surge protection device and connecting, described bypass diode and the protection of described bypass diode lightning surge one to one
Device simultaneously turns on, described lightning surge one to one protection device export at described bypass diode two ends one stable
Voltage, forms voltage-stabilizing protection.Lightning surge signal shared jointly by some lightning surges protection device, reduces lightning surge protector
The loss of part, increases the service life.
Operation principle of the present utility model is that described lightning surge protector is big high pressure when lightning surge signal occurs
The lightning surge of electric current is stable in its range of set value, make photovoltaic electrification component can under rated operational voltage normal work
Making, it is to avoid the high-voltage great-current impact to described bypass protection diode, cause protected assembly to be shorted, impact is normal to be sent out
Electricity, causes serious financial consequences.
This utility model implements the product device simple in construction of formation, dependable performance, low cost.
