Description
Technical field
The utility model relates to the photovoltaic generating system equipment technical field, especially relates to a kind of intelligent photovoltaic header box with anti-counter-function.
Background technology
At present; Along with the exploitation energetically of green energy resource, the photovoltaic generation industry development is swift and violent, and supporting with it equipment has formed huge industrial chain; Corresponding to large-sized photovoltaic be incorporated into the power networks or the photovoltaic module of stand alone generating system and inverter between line complicated; Intelligent photovoltaic generating system header box has appearred in the relatively poor and inconvenient maintenance of reliability for this reason, but present header box reliability is with to be that practicality still has to be hoisted.
The utility model content
In view of this, the purpose of the utility model is to provide a kind of intelligent photovoltaic header box with anti-counter-function, improves the reliability and the practicality of this kind header box.
For achieving the above object, the utility model adopts following technical scheme:
The intelligent photovoltaic header box with anti-counter-function of the utility model comprises photovoltaic cell tandem input, intelligent monitoring module, the output that confluxes, and also comprises lightning protection device and automatic reclosing; Photovoltaic cell tandem input anode links to each other with automatic reclosing with lightning protection device respectively through positive bus, and photovoltaic cell tandem input cathode links to each other with lightning protection device through negative bus-bar; Lightning protection device other end ground connection, the other end of automatic reclosing is connected with the said output that confluxes; Between said photovoltaic cell tandem input anode and positive bus, also be provided with the counnter attack diode, this counnter attack diode cathode connects photovoltaic cell tandem input anode, and the counnter attack diode cathode connects positive bus.
The beneficial effect of the utility model is:
The utility model has disposed the special-purpose lightning protection device of photovoltaic; And be provided with operating state indication and ceraunograph counting unit, current monitoring unit, voltage monitoring unit, environmental monitoring unit, self-powered module and wireless data transmission unit in described intelligent monitoring module; Make things convenient for the working condition of user's grasp photovoltaic cell promptly and accurately, guarantee photovoltaic cell performance maximum effect.It is to prevent solar module or square formation when not generating electricity that one of effect of diode is filled in counnter attack, and the electric current of storage battery send consumed energy to assembly or square formation conversely, and can make assembly or square formation heating even damage; Two of effect is in battery array, prevents that the electric current between each branch road of square formation from sending.This is because the output voltage on each road of series connection can not definitely equate; Each branch voltage always has the poor of height; Perhaps a certain branch trouble, shade such as cover at the output voltage that makes this branch road to be reduced; The electric current of high voltage branch road will flow to the low-voltage branch road, even can make the reduction of the overall output voltage of square formation.Daytime, solar cell was to storage battery power supply in addition, and when night, solar cell produces no-voltage, as did not have the counnter attack diode, and solar cell will become load, will damage solar cell like this.The generation that diode has just been avoided this phenomenon is filled in series connection access counnter attack in each branch road.
Other advantages, target and the characteristic of the utility model will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, take a hint to investigating of hereinafter.The target of the utility model can realize through the structure that is particularly pointed out in following specification and the accompanying drawing and obtain with other advantages.
Description of drawings
Fig. 1 is the electric logic diagram of the utility model.
Fig. 2 is the winding diagram in kind of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
In conjunction with illustrated in figures 1 and 2, the intelligent photovoltaic header box with anti-counter-function of the utility model comprises photovoltaic cell tandem input, intelligent monitoring module 6, the output 1 that confluxes, lightning protection device 7 and automatic reclosing 8; Photovoltaic cell tandem input anode 10 links to each other with automatic reclosing 8 with lightning protection device 7 respectively through positive bus 5, and photovoltaic cell tandem input cathode 9 links to each other with lightning protection device 7 through negative bus-bar 11; Lightning protection device 7 other ends link to each other with earth terminal 2, and the other end of automatic reclosing 8 is connected with the said output 1 that confluxes; Between said photovoltaic cell tandem input anode 10 and positive bus 5, also be provided with counnter attack diode 3, the positive pole of this counnter attack diode 3 connects photovoltaic cell tandem input anode 10, and counnter attack diode 3 negative poles connect positive bus 5.
The intelligent photovoltaic header box with anti-counter-function of the utility model is used for photovoltaic generating system, input direct current cabinet or inverter end of incoming cables after several photovoltaic modulies of organizing string are confluxed.Adopt intelligent, modularized design, have the cost performance height, outward appearance is beautiful, easy to install, efficient is high.
For reliability and the practicality that improves the utility model device; Disposed special-purpose lightning protection device, the dc fuse of photovoltaic in the header box of the utility model; Replace traditional dc circuit breaker with automatic reclosing, and be provided with operating state indication and ceraunograph counting unit, current monitoring unit, voltage monitoring unit, environmental monitoring unit, self-powered module and wireless data transmission unit through the intelligent monitoring module.Make things convenient for the working condition of user's grasp photovoltaic cell promptly and accurately, guarantee photovoltaic cell performance maximum effect.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Other modifications that those of ordinary skills make the technical scheme of the utility model perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of the utility model technical scheme, all should be encompassed in the middle of the claim scope of the utility model.
