Abstract
The utility model provides a novel intelligent photovoltaic conjunction box capable of monitoring a photovoltaic cell in all directions. The novel intelligent photovoltaic conjunction box comprises sensors connected with all photovoltaic cell panels. The sensors comprise current sensors and voltage sensors. The sensors are connected in series with a direct current breaker. The direct current breaker is connected in series with a direct current fuse. The direct current fuse is connected in series with a lightning protection device. The novel intelligent photovoltaic conjunction box of the utility model can monitor the cell panel operation state in a photovoltaic cell array, can measure the photovoltaic cell current, and can acquire the states of the lightning protection device and the direct current breaker. The currents of at most 16 photovoltaic assembly strings can be monitored at the same time, and all the monitored data can be sent to a monitoring background system by using a standard MODBUS protocol through an RS485. All the monitored data can be conveniently looked over through a nixie tube, the monitored data are displayed in a circulating manner, and the novel intelligent photovoltaic conjunction box can carry out data monitoring, query, statement analysis, pattern analysis, communication debugging and the like when cooperating with a function software.
Description
Technical field
The utility model relates to a kind of solar facilities, especially a kind of novel intelligent photovoltaic combiner box.
Background technology
Entered since the new century, the photovoltaic industry has become one of world today's new industry of greatest concern.Photovoltaic generation is to utilize photovoltaic cell effectively to absorb the solar radiation energy, and makes it to be transformed into the direct generation of electricity mode of electric energy, is the solar power generation mode of current main flow.Photovoltaic generation is pollution-free, safety, life-span long, it is simple to safeguard, resource is never exhausted and widely distributed characteristics.Being considered to " green " industry, is most important new forms of energy of 21 century, can be widely used in the fields such as space flight, communication, the energy, agricultural, office facility, traffic and private residence.
For photovoltaic generating system, in order to reduce the connecting line between photovoltaic array component and the inverter, improve power output, then can between photovoltaic array component and inverter, increase the direct current collector-shoe gear, to satisfy user's instructions for use.At present existing header box need be used the 220V Alternating Current Power Supply, and it is loaded down with trivial details to connect up, and whole photovoltaic system all is affected if will have a power failure or cut off the power supply then.Existing header box current protective device mostly is fuse, if but electric current surpasses its fuse of warning value burns out, need to change fuse, and the operating overload protector only need press the button and can automatically recover to connect, and need not to change device.But there is following shortcoming in this header box: 1, do not have lightning protection device, when being struck by lightning, can not protect inverter, 2, do not have a fuse of overload flow protection; 3, there is not detection module, can not be to the monitoring state of photovoltaic cell string, 4, existing accuracy of detection is inadequate, error is larger.5, can not accomplish self-powered for the header box that detection module is arranged, need 220v to power separately, the wiring trouble.
The utility model content
The utility model provides a kind of novel intelligent photovoltaic combiner box that can the conduct monitoring at all levels photovoltaic cell.
Realize the novel intelligent photovoltaic combiner box of the utility model purpose; comprise the transducer that links to each other with every road photovoltaic battery panel; described transducer comprises current sensor and voltage sensor; described transducer series direct current circuit breaker; this dc circuit breaker series direct current fuse, this dc fuse series connection anti-lightening protector.
The counnter attack diode of all connecting on described current sensor and the voltage sensor is used for preventing adverse current.
Described dc fuse comprises anodal dc fuse and negative pole dc fuse, guarantees the stability of follow-up work element.
Described dc fuse is the fuse of level Four series connection, improves the voltage protection grade.
The beneficial effect of novel intelligent photovoltaic combiner box of the present utility model is as follows:
Novel intelligent photovoltaic combiner box of the present utility model can be monitored cell panel running status in the photovoltaic battery array, photovoltaic cell current measurement, lightning protection device, dc circuit breaker state acquisition.Can monitor simultaneously the electric current of maximum 16 road photovoltaic module strings, can be by RS485, with standard MODBUS agreement all monitor datas are delivered to the monitoring background system, header box can be manual arranges the address.Can check easily all Monitoring Data by charactron, the Monitoring Data circulation shows that this device cooperates functional software, can carry out data monitoring, inquiry, statement analysis, pattern analysis, communication debugging etc.Cooperate the self-powered module, can directly use the electric energy power supply of photovoltaic array, convenient construction.
