In the system, the solar panel is used as the main supply source, and the high frequency switching power supply is started to introduce commercial power to complement the electricity of the storage battery in case of inadequate storage battery supply, thereby saving electric energy, providing stable and reliable supply manner for the communication base stations, and achieving energy conservation and environmental protection.
Description
Technical field
The utility model relates to solar energy and the complementary power supply technique of civil power field, and relating in particular to provides the working power aspect for communication base station.
Background technology
Because the geographical position particularity that communication base station is installed, has plenty of the remote mountain areas of being installed in, have on high mountain top, supply of electric power can not get effective guarantee, be subjected to the weather reason, rely on fully and solar poweredly can't satisfy electricity needs, if the dependence commercial power supply need set up special circuit and be connected with the 220V utility grid, because circuit is longer, resistance in the circuit is bigger, electricity decreases bigger, and the voltage that reaches the communication base station end is lower, and scope range of the fluctuation of voltage is bigger, influence communication quality, when serious even damage equipment.
Summary of the invention
In sum, the purpose of this utility model mainly is to solve the problem that the communication base station power supply is not ensured, and proposes a kind of solar energy and civil power complementary system.
For solving the problem that the utility model proposed, the technical scheme that adopts is: a kind of solar energy civil power complementary system, comprise: solar panel, controller for solar, storage battery, high frequency switch power and support is characterized in that: described solar panel is located at a top of the trellis of inclination; Described solar panel quantity is more than six, per two series connection are one group, the output in parallel of each group connects the sun-generated electric power incoming end of controller for solar, the output of controller for solar connects storage battery through high frequency switch power, connect civil power on the ac input end of high frequency switch power, connect load on the load output of high frequency switch power.
As the technical scheme that the utility model is further improved be:
Described load includes DC load and AC load, and DC load directly connects the load output of high frequency switch power, is provided with inverter between AC load and high frequency switch power.
Described solar panel has 12, is divided into 6 groups, every group of 2 series connection, and the maximum output voltage of 12 solar panels is 72V.
Include in the described high frequency switch power when switching to mains-supplied is the charging circuit of charge in batteries.
The threshold voltage that described high frequency switch power switches storage battery and mains-supplied is 51V.
The beneficial effects of the utility model are: the utility model is based on the solar panel power supply, be subjected to weather effect or night, the solar panel output voltage is low, when storage battery power supply is not enough, adopting high frequency switch power to open the civil power of introducing is that storage battery replenishes electric weight, jointly for load provides electric energy, and saves energy, for communication base station provides reliable and stable supply power mode, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of a plurality of solar panels of the present utility model;
Fig. 2 is a structure principle chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred a kind of embodiment structure of the present utility model is further described:
Shown in seeing figures.1.and.2, the utility model includes 12 solar panels 1 on the support 2 that is located at the inclined-plane, the battery sheet by 72 125mm*125mm of each piece solar panel is formed, the maximum output voltage of monolithic solar panel is 36V, peak power output is 175W, 12 solar panels 1 are divided into 6 groups, two series connection in every group, then by lead with 6 groups of parallel connections, for controller for solar provides a ceiling voltage is 72V, maximum power output is the power supply input of 2100W, controller for solar is connected with a high frequency switch power, connect storage battery on the high frequency switch power, civil power and DC load, and some must use the AC load that alternating current could work or directly use the alternating current load of aspect more (as: air-conditioning, computer) increases the inverter that an energy converts direct current to alternating current and between high frequency switch power.Wherein, controller for solar be used to control solar energy too the pond plate to charge in batteries, storage battery is to load discharge, and the device that storage battery is worked in trouble free service voltage, current range, its control performance directly influence the useful life and the system effectiveness of storage battery.It is 150A that controller for solar is set the max-flow of controlling charge in batteries, setting the control storage battery is 60A to the maximum current of load discharge, controller for solar detects the storage battery output voltage more than 51V, storage battery is undertaken being electric after the voltage stabilizing by the voltage stabilizing circuit of high frequency switch power, simultaneously, the additional electric weight of solar panel accumulators carries out work.Be subjected to weather effect or night, when the solar panel output voltage was lower than 51V, controller for solar control disconnection solar panel was connected with storage battery, prevents reverse charge.When the storage battery output voltage was lower than 51V, it was that storage battery replenishes electric weight by the transformation rectification circuit that the control high frequency switch power is opened the civil power of introducing, and is electric by high frequency switch power jointly.When the solar panel output voltage is not lower than 51V, and when storage battery occurring and electricity shortage occurring, solar panel, storage battery and civil power three power jointly, and saves energy is for communication base station provides reliable and stable supply power mode.
