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: Can someone help me out here. Please in layman's terms, to much detail is not necessary.
The hyphae is the thread-like filaments that form the structure of fungi. A mass of hyphae is called the mycelium. Upon the hyphae, spore bodies form to produce new fungal colonies. When the proper conditions occur, the hyphae of mating types fuse and form fruiting bodies such as mushrooms in which the sexually produced spores form and are released. The hyphae produces enzymes that digest the food they grow upon. These enzymes are called exoenzymes.

if the bike fits, it seems like a decent price. the sora components are entry level (you may already know this) and the 53t ring is awfully big for a beginer. whats the rear cassette like? the most important thing is fit. check your stand over height most else can be adjusted and new stems can be bought. consider upgrading the groupset when you have the chance though that will be more $ than you spent on the bike.
Q: I have a 2006 Toyota Corolla which the Toyota dealership claims has damage caused by jumping the car incorrectly. They say the car was damaged due to reversed polarity. I took the car to the local Autozone to have a free electrical system check before taking it to the Toyota dealership. Is it possible that the Autozone tech caused the damage by incorrectly testing the electrical system? Thanks for your help.
mroe likely then not you just need a new battery. check al the fuses and relays as well.
Q: have issue with couple of thing on a ford galaxy 1999 2.3 ghia w/airconis there a relay box in it as checked all fuses for the issuse i have and i lost even with the propper manual, rear passenger door wont open or window wont work, air con not workin and the blower that you can switch on to let air at ya face for cold or hot not working. now i havew done loads to the car and so far ive done well but this is bugging - can anyone help. what things have i missed.
Jay the controls for the windows and door are likely a problem in the drivers side control switches as this works as the main switch for all doors. I have seem this often when someone installed door speakers and unhooked the wires from the way they were tied down. the window came down and pulled them damaging the the wires. The A/C system and heater are hard to call over the computer but I can tell you the fan portion is not connected directly to either. it is a rheostat. a dimmer of sorts. The actual fan motor is built with a power and ground connection and is like all other electric 2 wire motors, a positive and a negative. If the motor isn't frozen inside the motor will spin even if the two wires are switched around as this is only changing it's polarity. what will happen though is your fan will draw air out of the cabin instead of pushing air in. It uses a connection screwed into the air box to control the various speeds. the power enters this device and then used power reducing components internally to slow the motor down or speed it up. your switch on the dash for fan speed feeds this controller. If you are saying you are getting no air to your face but the fan is blowing, I think you will find its blowing on the dash board. maybe the feet as well. This is a factory installed default for a problem in the heater or A/C directing system. It was determined that the most critical thing a driver needs when driving is a clear windshield in the cold of winter. You must be able to see ahead and can bundle up with clothes to keep warm. If the system looses the vacuum needed to run the directional doors to send air to your face etc springs will close the doors and direct the air to the windshield over every other place.
Q: a motor, a generator, a battery, or a fuse?
Generator: mechanical to electrical Motor: electrical to mechanical Battery: chemical to electrical Fuse: electrical to thermal, so that it melts to protect other components
Q: I have a 1000 watt insignia amp trying to power 2 12 sony xplods but everytime i connect power to the amp the fuses blow in it. I also have a fuse by the battery that hasnt blown. Everything is right and it should work, I have gone throught it like 100 times and I cant understand why the fuses are blowing. Someone said insignia is garbage and i should just replace the amp, is this true?
Ok, first off, the guy who said to use larger size fuse is wrong, and i pray he does not reproduce and infect the world with that kind of moronic thinking. The fuses are there for a reason, if you feel like frying your components, then by all means, put a higher fuse in there. Since they are blowing as soon as you connect power, I would guess you have a direct short to ground, which means somewhere, a wire is touching a ground where it shouldn't, this is a connection with little to no resistance, and it will be before any load in the circuit. Find it, fix it, then put the fuse in. A little trick I use wire up a test light to be able to stick in the fuse slot. Once you do this, there will be a load in the circuit, and you will not damage anything. Follow the line and find where it is shorting, if the light goes out, you know you just found where your short was and removed it, cover or replace exposed wire, replace the fuse, and be on your way. I know you said your ground is fine.and I'm sure it is. A ground wire being shorted to ground is no problem at all. You have a short in your power wire, somewhere between the fuse and the load. Its basics really, went here is a direct short to ground, then you will smoke every wire between the short and the battery, unless you have a fuse or circuit breaker, in which case, it will be between the fuse and the load.
Q: I have a 1987 ninja 750. i bought it and it turned on with an old battery but needed to be jumped to start. i bought a new battery . a duralast the one you add the acid in and charge. but now it wont turn on. a battery before that i added a new battery but i mixed up the terminals (pos on neg and neg on pos) did that mess up the electrical stuff or fuses or am i doing something wrong. hope to hear some help.
Do the ignition lights come on? Will it at least turn over but not start. I think we need more details.
Q: Hi i need to remove my fuse from my Nissan Serena Van 92 model, and i have looked at the fuse box, but nothing is indicating which fuse it is i take out. Can a electrician on here tell me which one it is to remove, and once removed will that effect anything else like lights, horn etc Thank you for any answers given
there should be a diagram in the owners manual that will show you which fuse to pull. Another thing is that there are usually two fuse boxes on vehicles, one either the passenger or driver door side of the dash, and one underneath the hood. the interior fuse box usually is for the interior components. I hope this helps and if not you can go to Auto Zone and let them know you need to know and they will help you out.
Q: from a circuit board, is this a resistor or a fuse?
3.15A 250WV fuse.
Q: If you add in cost of each component you will definetly win.Please reply soon. First to answer with good reply will win 10 POINTS!
no where near enough information. Purpose of circuit, number of additional circuits, are you tying into an existing circuit designing from scratch, Constant circuit, power option circuit (Turn signal, window, alarm) come on throw us a bone here Building a camping stove ehhhh? 12 volt D.C. heavy duty switch 60 ampre should suffice. Around 10 bucks 12 foot spool of 10 guage wire 15 bucks 10 guage inline fuse holder with 50 amp fuse 12 bucks Package of assorted wire ends 14 bucks (or solder and/or soldering iron) price of element unknown (never bought one before) Interstate Battery re-manufactured $25, new $90, deep cycle new $125 60 amp rheostat (to control temperature) 45 bucks Assuming you are talking about a heating element
