Technical field
The utility model relates to a kind of photovoltaic generation control cabinet.
Background technology
solar energy power generating is to rely on solar module, utilize the electronics property of semi-conducting material, when solar light irradiation on semiconductor PN, because P-N junction barrier district has produced stronger built-in electrostatic field, thereby be created in nonequilibrium electron and the hole in barrier region or be created in outside barrier region but diffuse into nonequilibrium electron and the hole of barrier region, under the effect of built-in electrostatic field, motion round about separately, leave barrier region, result raises P district electromotive force, N district electromotive force reduces, thereby produce voltage and current in external circuit, light energy conversion is become electric energy.
Solar photovoltaic generation system can be divided into two classes substantially, and a class is grid-connected system, namely with utility network, by standard interface, is connected, as a small-sized power plant; Another kind of is free-standing electricity generation system, namely at the inner circuit that forms of the closed-circuit system of oneself.Grid-connected system will receive the solar radiation energy that comes and become high voltage direct current after high-frequency direct-current is changed by the photovoltaic array, through the backward electrical network output of inverter inversion and the simple sinusoidal alternating current of line voltage with frequency, homophase.And at first free-standing electricity generation system photovoltaic array can be directly changed into the electric energy supply load with receiving the solar radiation energy that comes, and excess energy form with chemical energy after charge controller is stored in storage battery, be not exclusively used in the market the measurement control box of photovoltaic generating system.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of photovoltaic generation control cabinet that is exclusively used in grid-connected photovoltaic system is provided.
The purpose of this utility model realizes by following technical solution:
A kind of photovoltaic generation control cabinet, comprise casing, it is characterized in that: described box house becomes inverter chamber, ammeter chamber and switchgear house by baffle for separating, inverter chamber, ammeter chamber and switchgear house all are equipped with independently chamber door, inverter is equipped with inverter in chamber, ammeter is equipped with ammeter in chamber, power distribution assembly is installed in switchgear house, inverter input terminal is connected with the solar panel of peripheral hardware, output is connected with the ammeter input, the ammeter output connects power distribution assembly, and the output of ammeter also is connected with electrical network can export inverter electric energy feed-in electrical network.
Further, described inverter chamber is positioned at the left side of casing, and described ammeter chamber is positioned at the upper right side of casing, and described switchgear house is positioned at the lower right side of casing.
Further, be provided with data display screen on the chamber door of described inverter chamber, this data display screen is connected the running parameter information that is used for showing inverter with inverter.
Further, be formed with observation window on the chamber door of described ammeter chamber, be provided with the perspective protective cover on observation window.
The utlity model has following beneficial effect:
Inverter in the photovoltaic generation control cabinet can become dc inverter alternating current and via ammeter feed-in electrical network, ammeter can be measured the actual power consumption outside deduction solar power generation amount, and the control cabinet that the utility model provides has the advantages such as simple in structure, with low cost.
The specific works mode is: when sunlight is arranged, the dc inverter that inverter is sent out photovoltaic system becomes sinusoidal ac, the alternating current that produces can directly be supplied with AC load, and then with remaining electric energy input electrical network, whole electric energy that perhaps directly will produce are connected to the grid.There is no the solar time, the load electricity consumption is all supplied with by electrical network.
Grid-connected photovoltaic power generation system has many superiority, can be summarized as following some:
1) utilize clean, the reproducible solar power generation of cleaning, do not consume fossil energy, without greenhouse gas and pollutant emission, harmonious with biological environment in use, close sustainable development of socio-economy strategy.
2) generate electricity can feed-in electrical network,, take electrical network as energy storage device, save storage battery, reduce 25%-30% than the construction investment of angle of solar battery system, thereby cost of electricity-generating greatly reduced.Save the secondary pollution that storage battery also can improve the mean free error time of system and avoid storage battery.
3) photovoltaic cell component and building perfect adaptation not only can be generated electricity but also can make physical resources take full advantage of the performance several functions as construction material and ornament materials, not only are conducive to reduce cost of erection, and the building scientific and technological content is improved, and increase " attraction ".
