Work principle and features

Working principle: Wind energy is used as the motive power to provide low speed rotation of a permanent magnet generator to produce alternating current which is then converted to direct current by a controlled constant voltage rectification system, the resulting voltage being stored in a battery, or batteries. The direct current from the battery, (batteries), is then converted to alternating current by an inverter, the resulting controlled and stabilised alternating current being used to power the load, this is the general principle for battery storage type systems. Grid connect systems take the alternating current produced by the turbine directly to an inverter which controls and stabilises the alternating current and also provides numerous control elements for direct connection to the electricity grid.

Features : The products combine unique and innovative design with high reliability. The innovative design has been awarded both Invention and Practical new patents by the State Intellectual Property Department and thereby has totally independent property rights in China, resulting in the market leading position in wind to electrical energy conversion, technical design and efficiency. Key design features such as very low rotation speed result in increased efficiency in comparison to other small turbine systems.

Applications and installations

The products are used in areas that benefit from good wind regimes but have little or no electrical grid connection such as; islands, desert and low inhabitation areas, frontier defence posts, microwave and telephone communication stations, forest observation posts, oil pipeline delivery stations, highway lighting etc. Rural and urban applications include, community squares and recreational areas, parks, landscape and scenic locations, resorts, and other ecological areas, applications also include on or off grid national electrified fencing systems.The utilisation of wind energy at no on-going cost significantly reduces the environmental impact of fossil fuel usage whilst saving vital energy resources.

Q:Fuse keeps going out in my car?
Either you have an intermittent short to ground in the wiring or something on the circuit (motor, for example) is adding resistance and subsequently pulling excessive current because it is binding/starting to fail etc. and causing the circuit to overload and the fuse to pop. Is there anything else on the circuit that you know of? Do the power seats move smoothly and consistently on the tracks? Some cars have several motors that control the power seats so it can get complicated if one of them is the culprit. If it is not in the wiring and a component is causing it it sometimes it is easier to wait for the problematic component to take a sh*t and then just replace it. That's about the best that I can say over a computer. Good luck!
Q:1988 chevy 1500 electrical problem.?
the dash wire harness has a ground wire that hooks to the steering column support bracket. even if its hooked up reposition it for a good contact.
Q:Overheated PS3 on accident?
your husband might be wanting to kill you now haha
Q:Automotive fuse boxes?
Gandalf waves his wand and magic happens? Of COURSE there's a wire, you NOOB! If you want a diagram of the electrical system in your car then go buy a service/repair manual for your car. They have wiring diagrams in them.
Q:96 Chrysler Concord fuse?
I know you said that you checked the fuses ,but did you check both fuse boxes .You should have one under the dash and another one under the hood. It sure sound like you have a blown fuse to me.
Q:Why did the digital display instrument cluster go dark in my 1991 Cadillac Brougham?
Replace fuses When water comes in contact with a electrical component bad things can happen.
Q:What is electrical drainage and is it cheap to fix?
Basics are: Remove fuses and relays one at a time to find circuit that is draining the battery. Refer to your vehicle owner's manual or a wiring diagram to identify the fuses and relays. Then pull the fuses and relays one at a time until the current reading drops. Avoid pulling the fuses for the PCM or other KAM-sensitive modules until you have checked all of the other circuits. Once you've found the circuit that is causing the excessive current drain, check the relay, switch, module or other components in the circuit and replace as needed. Sometimes a bad alternator diode can cause a battery to run down. A good diode should only pass current in one direction. If it leaks current in the opposite direction, it may keep the charging circuit on when the engine is not running, causing the battery to run down Causes of excessive current drain in late model vehicles include things like lights that remain on (trunk and hood lights, interior lights, brake lights, etc.) and also relays that may be stuck on, or modules that are not going to sleep or powering down. A fuel pump relay that sticks on may keep the fuel pump running after the engine is shut off. A switch or relay that powers a rear window defogger can stick on, pulling current from the battery after the ignition is off. An electronic suspension module, ABS module or keyless entry module may remain active long after it should have powered down.
Q:do i have to replace the whole part in a 1997 ford thunderbird back lights and blinkers?
Either the turn signal switch or turn signal relay. If the green light comes on when you put the lever in the turn position, check for burned out bulbs, front and rear. If the bulbs are OK, replace the flasher relay. Master tech 40 yrs.
Q:1992 grand am start up problems?
Sounds like the fuel pump fuse.try looking under the dash or on the side of the dash when you open the door.if it isn't there it will be under the hood.I would reccomend you go to your local autozone and purchase a $15 book on your car!! not only will it help you find those pesky relays and fuses.but it will also have a wiring diagram to show you where that disconnected wire goes.but don't fret if you can't find that because sometimes car manufacturers use wiring harnesses for different cars and option packages and that wire may not be used for your vehicle.although given it's location my guess isthat it goes somewhere.Buy a book if you are going to be doing your own work on the car.it is a invaluable investment!!!!!!!!!
Q:3 of 4 Electric stove top not working?
Those coils do go bad. Plus it could also be a problem with the transformers burning out for each coil. Call a repairman.
