Description
Technical field
The utility model belongs to solar cell output control technology, is specifically related to a kind of solar panel direct current collector-shoe gear.
Background technology
Solar energy power generating has obtained application more and more widely as a kind of clean energy resource mode.In photovoltaic generating system, the first step will be carried out connection in series-parallel with solar photovoltaic cell panel exactly, the branch road after the connection in series-parallel is linked in the header box confluxes then.Traditional header box generally can only satisfy branch road and conflux and simple loop protection function; if some solar panel decreased performance is unusual or wiring is unusual in electricity generation system; general being difficult to found; after can only carrying out the craft inspection to all cell panels of electricity generation system; all are normal just to guarantee system works; but solar panel quantity is huge in the photovoltaic generating system, so the workload of spot check is very big, can not often carry out.So may generation systems often not be to be operated in best generating state, cause waste.
The purpose of this utility model is to provide a kind of can realize that the output to cell panel realizes the solar panel intelligence header box of monitoring, addresses the above problem.
Solar panel intelligence collector-shoe gear, it comprises the binding post that confluxes of solar panel, busbar confluxes, be connected in parallel between the busbar each line conductor of solar panel of the binding post and confluxing of confluxing, the lightning protection device that connects between the output both positive and negative polarity of busbar and the lead-out terminal that confluxes conflux, be in series with current transducer on each line conductor, be connected with voltage transmitter between the output both positive and negative polarity of the busbar that confluxes, the output of current transducer and voltage transmitter is connected the communication measurement and control unit respectively.
Described communication measurement and control unit adopts RS485 interface (communications protocol is standard Modbus), magnitude of voltage and current value can be sent to the Central Control Room computer by RS485 interface (communications protocol is standard Modbus)
The utility model is owing to introduced current transducer and voltage transmitter in existing solar panel collector-shoe gear; make this device can satisfy that traditional header box confluxes and defencive function outside; can also gather the electric current and the voltage of each branch road that confluxes in the header box in real time; and the information of electric current and voltage can be delivered to power station Central Control Room computer by RS485 interface (communications protocol is standard Modbus); in case the electric current of certain branch road differs from other branch roads; supervisory control system can be sent prompting at once; the attendant can know very in time that branch road breaks down, thereby fault loop is checked and got rid of fault.So just can guarantee electricity generation system always in the optimum Working operation of oneself, guarantee that system has given play to maximum operating efficiency.This device is simple, stable.
Description of drawings
Fig. 1 solar panel intelligence apparatus structure schematic diagram that confluxes.
Embodiment
As shown in Figure 1, be connected in parallel between the busbar 2 each line conductor of solar panel of the binding post 1 and confluxing of confluxing, each branch road direct current both positive and negative polarity group realizes confluxing; The lightning protection device 3 that connects between the output both positive and negative polarity of the busbar that confluxes after the busbar 2 of confluxing refluxes and the lead-out terminal 4 that confluxes are connected with direct current air switch 5 at the input of the lead-out terminal 4 that confluxes.The fuse 6 that is connected in series respectively, diode 7 and current transducer 8 of the binding post 1 and each anodal the line conductor between the busbar 2 that confluxes conflux.Conflux and be connected with voltage transmitter 9 between the output both positive and negative polarity of busbar.Current transducer 8 can adopt Hall closed loop current transducer or dc pulse current transducer, and voltage transmitter 9 can adopt the Hall voltage transmitter.The output of each current transducer 8 is connected communication measurement and control unit 10 with the output of voltage transmitter 9.
The communication measurement and control unit receives the 4～20mA or the 1-5V standard signal of voltage transmitter and current transducer, be converted into correspondent voltage value and current value and RS485 interface (communications protocol is standard Modbus) is provided, magnitude of voltage and current value can be sent to the Central Control Room computer by RS485 interface (communications protocol is standard Modbus).
Utilize the characteristic of the unidirectional conducting of diode, when the both positive and negative polarity that confluxes connects inverse time, the header box circuit is equivalent to open circuit, the protection electricity generation system.
During operate as normal, solar panel branch road after the connection in series-parallel inserts through the binding post (differentiation both positive and negative polarity) that confluxes, anodal branch current is by fuse 6, diode 7 and current transducer 8, busbar 2 confluxes confluxing, electric current after confluxing picks out through the lead-out terminal 4 that confluxes by behind the direct current air switch 5 again.When the voltage that confluxes or a certain solar panel branch road occur when unusual, voltage transmitter or current transducer can detect at any time, and by the communication measurement and control unit this abnormal data are sent to the Central Control Room computer.
