Description
Technical field
The utility model belongs to solar energy generation technology field, is specifically related to a kind of photovoltaic battery matrix and grid-connected photovoltaic system.
Background technology
Solar energy is a kind of emerging green energy resource, because it is clean, efficiently, never exhaustion and be not subject to region resource limitation, therefore have safe and reliable, noiseless, pollution-free, be subject to restriction less, the advantage such as failure rate is low, easy maintenance, the every field that can be widely used in social life, particularly can form photovoltaic battery matrix and be applied in grid-connected photovoltaic system.In grid-connected photovoltaic system, the direct current that photovoltaic battery matrix can be produced is converted to the same amplitude of line voltage, the alternating current of frequency, homophase, and realization together and is connected with electrical network through combining inverter.At present, the large-sized photovoltaic electric system construction of tens megawatts megawatts even up to a hundred, power plant's quantity of generating electricity by way of merging two or more grid systems are just increasing.
Combining inverter and step-up transformer are the more equipment of number in photovoltaic plant, install, debugging work load is large.And, the voltage not high (conventionally only having 270V to 315V) that combining inverter exports step-up transformer low pressure input side to, but electric current is very large, meet or exceed 1000A, therefore, not only difficulty of construction is large, and butted line technological requirement is high for this part tie cable wire diameter large (conventionally reaching 185 to 240mm2), coupling head and cable long-term work are under current state, and failure rate is also very high.
Voltage, electric current, transformer temperature, high-voltage switch gear position, the remote signal of the signals such as the voltage of combining inverter itself, electric current, power and step-up transformer all depend on communication device and are transferred to control room, in Practical Project construction, also need to connect signal cable, be subject to communication cable to connect technogenic influence, often cause communication debugging work load large, easily produce communication and disturb fault etc.
Summary of the invention
The purpose of this utility model is as much as possible the core components such as the related combining inverter in power station, step-up transformer to be concentrated in together to intensive management.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of desert of the utility model power station inversion boosting all-in-one, comprise container, DC cabinet, combining inverter, dry-type transformer, high-tension switch cabinet and low-voltage distribution cabinet, described DC cabinet, combining inverter and dry-type transformer are connected successively and are arranged on side by side in container, and described high-tension switch cabinet and low-voltage distribution cabinet are separately positioned on dry-type transformer both sides and control its final Voltage-output.
Further, also comprise communication device, described communication device is arranged between described combining inverter and dry-type transformer.
The utility model is the equipment of one that is arranged in a kind of combining inverter and dry-type transformer combination of sets, by combining inverter and dry-type transformer centralized arrangement in a casing, electric wiring can be very short path configurations install, especially can shorten the wire connecting length that combining inverter is exported to step-up transformer porch, than being easier to realize bus, connect simultaneously, further strengthen connection reliability.The equipment that heat dissipation capacity is larger can be concentrated design heat dissipation wind channel as inverter, dry-type transformer and dispel the heat, inverter and transformer have been reduced as the cooling fan quantity of specific installation, improved utilization rate of equipment and installations, improved the efficiency of photovoltaic system, not only reduced the quantity of single devices, and, by a large amount of fitter's work batch production, minimizing project site operation cost, has raised the efficiency very important meaning.
