Abstract
The utility model provides an anti-static photovoltaic connector. The anti-static photovoltaic connector comprises at least one diode, and each of the diodes is connected in parallel with a protection diode. In a junction box for a photovoltaic panel, which is provided by the utility model, diodes in the junction box are connected in parallel with protection diodes, so that when the reverse voltage on the diodes is on the point of the limit of reverse voltage resistance due to static electricity and other reasons, the protection diodes generate reverse high current to release electric energy to protect the diodes against reverse breakdown and further ensure the normal use of the junction box for the photovoltaic panel and photovoltaic components. Therefore, the anti-static photovoltaic connector has a very good popularization prospect.
Description
Technical field
The utility model relates to photovoltaic module, particularly the antistatic photovoltaic connector.
Background technology
Along with the mankind are more and more higher to requirements of saving energy, the utilization of solar energy obtains development energetically, thereby the application of photovoltaic panel obtains promoting.Photovoltaic module is to be assembled by a plurality of photovoltaic cell sheets, each photovoltaic cell sheet produces the low-voltage electric energy, photovoltaic module forms the electric energy of high voltage by these low-voltage electric energy of series connection, and the electric energy output lead is set, these electric energy output leads are connected with the photovoltaic panel terminal box, and by the more high-tension electric energy of the formation of the diode rectification in the photovoltaic panel terminal box, the electric energy of exporting from photovoltaic junction box forms the electric energy that can be connected to the grid by rectifier systems such as inversions again.
The reverse withstand voltage that is used for the interior diode that uses of terminal box of photovoltaic panel is generally about 40V, because the magnitude of voltage of the electric energy that produces on the photovoltaic panel is not very stable, the voltage that is higher than the diode reverse withstand voltage that transient state often occurs, the perhaps static that produces in process of production, the phenomenon of puncture often appears being reversed in diode, and the breakdown back of diode photovoltaic panel terminal box just can not normally be used, thereby influences the normal use of overall optical photovoltaic assembly, causes very big loss.
At present; go back the good method of neither one for the protection of diode in the terminal box that is used for photovoltaic panel; can only change the terminal box that is used for photovoltaic panel in the breakdown back of diode; therefore on the diode in being used for the terminal box of photovoltaic panel protective device is set, becomes key subjects being badly in need of solution.
Summary of the invention
At above-mentioned defective; the antistatic photovoltaic connector that the utility model provides; protection diode in parallel on the diode in terminal box; owing to the reason of static when the reverse voltage on the diode is about to reach the reverse withstand voltage limit; the protection diode produces reverse high electric current electric energy is discharged; thereby the protection diode can not be reversed puncture, and then guarantees to be used for the terminal box of photovoltaic panel and the normal use of photovoltaic module, has fine promotion prospect.
The antistatic photovoltaic connector that the utility model provides comprises at least one diode, protection diode in parallel on each above-mentioned diode.
Preferably, it is characterized in that above-mentioned protection diode is that transient voltage suppresses diode.
Preferably, above-mentioned terminal box comprises three diode in series, and a transient voltage in parallel respectively suppresses diode on this diode.
The reverse withstand voltage that is used for the interior diode that uses of terminal box of photovoltaic panel is generally about 40V, because the magnitude of voltage of the electric energy that produces on the photovoltaic panel is not very stable, the voltage that is higher than the diode reverse withstand voltage that transient state often occurs, the perhaps static that produces in process of production, the phenomenon of puncture often appears being reversed in diode, and the breakdown back of diode photovoltaic panel terminal box just can not normally be used, thereby influences the normal use of overall optical photovoltaic assembly, causes very big loss.The terminal box that is used for photovoltaic panel that the utility model provides; protection diode in parallel on the diode in terminal box; owing to reasons such as static when the repercussion voltage on the diode is about to reach the reverse withstand voltage limit; the protection diode produces reverse high electric current electric energy is discharged; thereby the protection diode can not be reversed puncture; and then guarantee to be used for the terminal box of photovoltaic panel and the normal use of photovoltaic module, have fine promotion prospect.
In the preferred version of utility model, it is a kind of more common diode as protection that transient voltage suppresses diode, and the response time is about 1NS, and response voltage scope and transient power can be chosen as required.
Description of drawings
Fig. 1 is the connection diagram of the utility model embodiment 1.
Embodiment
Below the embodiment 1 that provides for the utility model.
As shown in Figure 1, the antistatic photovoltaic connector that the utility model embodiment 1 provides comprises three diode in series (1), goes up a transient voltage in parallel at each above-mentioned diode (1) and suppresses diode (2).
The reverse withstand voltage of above-mentioned diode (1) is 40V, the inhibition voltage range that transient voltage suppresses diode (2) be 35V to 38V, transient power 1500W, response time 1ns.
The antistatic photovoltaic connector that the utility model embodiment 1 provides; the inhibition voltage range of the protection diode that uses arrives 38V as 35V; and the reverse withstand voltage of diode is 40V; when static that photovoltaic connector is subjected to reaches 35V in the scope of 38V; transient voltage suppresses diode will produce the oppositely big electric current of transient state; electric energy is discharged; thereby can not allow the reverse voltage of diode reach 40V; thereby the normal use of protection diode; and then guarantee to be used for the terminal box of photovoltaic panel and the normal use of photovoltaic module, have fine promotion prospect.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
