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 somebody please explain the parts marked in red on the following image
The item on the left is a fuse rated at 200mA. The 47k items are 47 k ohm (47000 ohm) resistors. I have no idea what the circuit does, but at the 4 pin connector on the right, provides voltages of, from the bottom pin up, 0, 2.5 volts, 2.5 volts, and 5 volts. .
Q: I turned on my truck the other day and suddenly my radio, dome light and power locks did not work. I wouldn't think all of these would be on the same fuse, but I don't know much about that stuff. Could it be a bad ground wire?
Radio and dome light are commonly on same fuse in many vehicles today. Depending on what you drive, the fuse panel could be at the end of the dash on the driver side (have to have the door open to find it) or under the dash on the driver side, or under the dash on the passenger side. Some vehicles have a secondary fuse block in the engine compartment, but this is not where the radio/dome fuse would be. Good luck in the fuse replacement.
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: I put new fans cooling and ac,, new fan relay. And new tempeture sensor and don't work my ac fan and cooling fan . I check the all fuses are in good condition .,only I have to change the auxiliary switch to see if that is the problem.,
I can't imagine why anyone would replace all these components that are easily tested with a simple test light? For example, you can't be sure of fuses by looking at them. You have to use a test light. You need to start at one end of the flow and work to the other. Might be easiest to start at the radiator temp sensor. If you shunt that, the relay should kick the fan on. If not, then check power to the relay at the relay. And don't forget grounds. For example, power to the fan is not enough. It also much have a good ground connection wire. You can get a test light at a place like Harbor Freight for $1.
Q: connectors on the backglass. no damage to the defroster grid. is there an inline fuse in the lift gate that i might have missed, or could the switch be bad and still light up?
You won't get power to grid because it goes to ground. You'll have to unplug it at the connector near the grid and read the grid with an ohm meter. If it's open, you may be able to see where its damaged. Sometimes when you clean or scrape frost from the inside glass, or maybe when you loaded something the grid got damaged. . The grid can be damaged pretty easy. Your favorite auto supply will have a repair kit for your defroster grid. You won't see wires go from the body of the car to the components of the tail gate.There is a pressure connector that makes this connection. On one side there will be a plate with dividers on it. On the other side you'll see the pins that are spring loaded. They line up and touch each other when the tail gate is closed. They stick out about 1/4 inch. You can clean this plate with a pencil eraser. Do the same with the pins. Use a little di electric grease on them. This is where the tailgate components are grounded. These components are activated by switching the ground. That's why you won't read power at the component.
Q: any suggestion to fix them would be appreciated.
Sounds like a fuse to me. A fuse can actually blow and not look like it. Go ahead and change it out. If you remove the fuse box cover, there will be an illustration that would show you which fuse to pull.
Q: a. short circuit b. series circuitc. switch d. parallel circuit e.fuse f. electric power
Answer b) A series circuit only has one possible path for the electrons to move.
Q: 1. Protection against disease2. Communication between cells, tissues, and organs3. Oxygen transport4. Carbon Dioxide transport5. Buffer against pH changes6. Nutrient supply7. Tissue repair8. Transport of hormones, lipids, and fat soluble vitamins Hurry!!!!!!!!!!!!!!!!!!!!!11
1: Could be White Blood Cells and other immuno cells 2: Hormones 3: Hemoglobin located on red blood cells 4: Carbonic An hydrase (which fuses CO2 molecules into a bicarbonate for transfer in the blood) as well as carbamino hemoglobin located with red blood cells and some plasma transports small amounts of diffused CO2 5: Red blood cells hemoglobin and bicarbonate are 2 major blood pH buffers 6: Don't know what you mean cause glucose, amino acids and fatty acids/ other monomers float freely for the most part in the blood (plasma if you want the correct portion of blood) 7: If by tissue you mean clotting then platelets and clotting proteins like fibrin/fibrinogen 8: Carrier proteins carry those things. or they float freely anything thats a protein or cell is part of the solid component anything not manufactured by the body is plasma portion, e.g. glucose, amino acids and such been awhile since I did circulation so I hope thats pretty accurate
Q: I changed all the bad fuses, then I changed the switch, then I tested the motor by hooking up a 12V battery pack, and it worked just fine up and down. What else could be the problem and how do I test it?Also, the window and the door lock mechanisms don't work on the passenger front door, even from the master control on the drivers side door.
the window has a plastic belt on it behind the door panel that has broken or the teeth on it has stripped out.You can get the parts anywhere now.
Q: I have BOSS Bass1500 with 25A fuse hooked onto 8GA 1000W 40A metra kit. Annoyed with low output I bought a 2 way subwoofer crossover SOUNDSTORM SX210. SOUNDSTORM SX210 kit requires a 3A fuse from the battery to crossover.What if I run a 10GA cable to power the crossover through my amplified subwoofer?Also, run the remote wire through the amplified subwoofer to crossover?Doesn't make sense laying 2 power cables running from the battery to 2 different things and 2 separate remote wires from the head unit.What do you guys think?
For the main power you can use a distribution block that splits the power two ways. just cut the main power wire (with the battery disconnected of course!) and connect them back up again via the d block. then run your 10GA wire from the d block to your crossover. Don't forget to put fuses in between the distribution block and the components though. A 25 amp fuse for the sub and a 3 amp fuse for the crossover. For the remote wire you can simply tap into the one already running to you sub. there are connectors for this that you can buy from any electrics store. Good luck. Ben.
