Specific implementation mode
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present embodiment provides a kind of marine radar power supply systems powered based on solar panels and accumulation energy type Combined storage battery It unites, by rational deployment, solar panels can be made to power with accumulation energy type accumulator complementation, and have intelligent control protection and prevent certainly Thunder function can ensure that marine radar is unmanned on duty under severe complicated marine environment, and can be safe and stable, uninterrupted Work.
The power-supply system includes solar panel group, accumulation energy type accumulator group, lightning protection device and integrated power supply, wherein Solar controller, power conversion module and power supply shift control module are provided in integrated power supply.Its basic principle such as Fig. 1 Shown, solar panel group and accumulation energy type battery component after lightning protection device with integrated power supply by not being connected, integration Power supply passes through reverse transformation, and required 220V voltages are exported to load equipment by power output interface.
In the present embodiment solar panel group include 48 pieces of 36V solar panels 1, wherein every 12 pieces of solar panels 1 be one too Positive energy plate unit, is thus divided into 4 solar panels units by solar panel group.Too by 12 pieces in each solar panels unit first Positive energy plate is in parallel, then that 4 solar panels units are in parallel.Solar panel group by the way of in parallel, grouping, power supply safety, Reliably;One piece of any of which or even any one solar panels unit 1, which break down, will not all cause in electricity shortage or power supply It is disconnected.
Solar panel group uses the layout type described in Fig. 2 according to marine radar use environment, specially:Laying the sun Before energy board group, the longitude and latitude in geographical location is laid according to marine radar, calculates local intensity of sunshine and solar incident angle, rationally Design the placement angle of single solar panels.48 pieces of solar panels are uniformly divided according to all directions four direction in the present embodiment Cloth, and contain the solar panels of identical quantity different directions direction, i.e., each solar panels in each solar panels unit Each 3 pieces towards the solar panels of all directions four direction in unit.Such layout type so that solar panel group is round-the-clock Sunlight can be fully received, and then it is other load equipment power supplies on marine radar to be converted into electric energy, is substantially increased The working efficiency of solar panel group.And this layout type also ensures 4 solar panels units round-the-clock every time Output power is almost the same, it is ensured that it is unmanned on duty to improve marine radar for marine radar electric system long-term working stability Service ability.
Solar panels are mounted on by holder 2 on the deck of marine radar, it is contemplated that marine radar lays geographical location Monsoon climate, for the structure of the holder 2 as shown in figure 3, every two pieces of solar panels share a holder 2, holder 2 includes a bottom Face and two sides, cross section are isosceles triangular structure.The bottom surface level of holder 2 is affixed above deck, two side Above each to fix a solar panels, thus two solar panels form herringbone, reserve air duct among it, as shown in Figure 4.It should Kind of mounting means can improve marine radar monsoon climate lower platform stability.
Accumulation energy type accumulator group uses 8 pieces of 12V plumbic acid accumulation energy type accumulators, accumulation energy type accumulator to be divided into 2 in the present embodiment A secondary battery unit, each unit by 4 pieces of plumbic acid accumulation energy type accumulators using first two-by-two series wiring mode again in parallel connect and At using the mode of connection in parallel between two secondary battery units.Accumulator, can be effective in such a way that grouping, connection in series-parallel combine Raising accumulator input and output voltage, the normal power supply of proof load equipment.Working as in each battery simultaneously has one piece to go out Have in existing failure or two-way accumulator when breaking down all the way, still ensures that the normal work of battery system will not be by shadow It rings.
The solar controller embedded in integrated power supply, effect are utilization and the accumulation energy type accumulator group to solar energy Charge and discharge carry out intelligent control and protection.Specially:In the case of sunshine abundance, when the electric energy of solar panel group conversion is enough full When sufficient load equipment power reguirements, the electric energy for ensureing solar panel group conversion can by integrated power supply reverse transformation after it is straight It connects on the basis of powering to load equipment, remaining electric energy gives accumulation energy type battery charging by solar controller;When too For the electricity of positive energy board group conversion it is impossible to meet when load equipment power reguirements, integrated power supply realizes UPS's (uninterruptible power supply) Function, control accumulation energy type accumulator group release electric energy are powered to load equipment, to ensure what equipment can uninterruptedly be stablized for a long time Work.
The solar controller can acquire the voltage status of accumulation energy type accumulator group simultaneously, and control solar panel group is to storage The output current of energy type battery charging, to control the charging rate of accumulation energy type accumulator group (i.e. when accumulation energy type accumulator When the voltage of group is higher, reduce the output current to accumulation energy type battery charging, to slow down to accumulation energy type accumulator group Charging rate) prevent accumulation energy type accumulator group overcharge;When powering to load equipment using accumulation energy type accumulator group, pass through electricity The output current of source shift control module control accumulation energy type accumulator group, prevents its overdischarge, ensures accumulation energy type accumulator group Normal use extends the service life of accumulation energy type accumulator group.
It is supplied using solar panel group, accumulation energy type accumulator group and the integrated power supply composition complementary of embedded solar controller The power supply mode of electricity.Plumbic acid accumulation energy type accumulator has good low-temperature characteristics, charge characteristic and non-maintaining characteristic.
It is natural in thunder and lightning etc. that lightning protection device in the system can prevent marine radar power-supply system and load equipment Under the conditions of be struck by lightning, protection can be automatically powered off in lightning stroke by realizing, guarantee marine radar power-supply system is badly complicated in ocean Safe and reliable operation under environment.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention. All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's Within protection domain.
