The power of the generator is based on the power of the equipment in the home multiplied by 3 times the starting current. For example: the power of the rice cooker is 200W, the induction cooker is 1200W, the total is 1400W 1400 times 3 = 4.2KW (equal to the generator power).
When choosing a generator, you should consider the following points:
Step one: Determine the power of the electrical equipment. If the power of the electrical equipment is 300KW, then it is not possible to choose a 300KW generator. Yes, because there is also a starting current to consider. Electrical equipment must overcome inertia to perform work when starting, and the starting current is generally 2-7 times the actual current.
Step 2: Choose the diesel engine brand of the generator. Knowing the starting current can determine the size of the generator to be used. As for the performance indicators of the generator, the diesel engine accounts for a large proportion because of the power of the generator. The source is a diesel engine, which has sufficient power, is easy to maintain, and has a low failure rate.
I want to make a small household wind turbine (DC motor to generate electricity). Who can explain the process, principle (and gear matching)? If you answer well, high score will be awarded
If you only buy a wind turbine, you only need 2,000-3,000 yuan. If you want a high-power one, the price will be higher. It depends on how powerful you want it to be. Guangzhou Shangneng Wind Power Co., Ltd. produces small wind turbines. You can You can contact them, I have used them, they are good
Small household wind turbines
Power generation process:
Wind blades---gearbox-- - DC motor---rectifier bridge (polarity protection)--battery
Principle:
The wind rotates the blades (similar to electric fan blades) to drive the gearbox to make DC When the motor speed exceeds the rated speed, the voltage generated by the motor will be equal to the motor working voltage. Generally, 12V or 24V is selected because the battery generally has these voltages.
Difficulty:
To make a gearbox, you need to calculate the transmission ratio. For example: the rated speed of the motor is 3000, the fan blade rotates 10 times per minute, and the motor end reaches 3000 through the gearbox. rpm. At this time, the transmission ratio is 1:300.
The above data are obtained from the small-power hand-operated generator model I have made and are for reference only.
24 hours multiplied by 500w equals 12000w or 12kw.
I guess the poster is doing engineering inspection.
The average daily wind speed is 7-8m/s How many hours can it last?
We assume that it is only 4-5 hours in general areas. Then you need about a 3kw fan, which can supply 12kw to 15kw power every day. The premise is that you have to ensure that there is so much wind every day. .
If the wind speed is very good and is greater than 7m/s for 12 hours or more every day, then you can choose a 2kw fan.
As for the battery, it is recommended to choose at least 10 Block 12v 150AH battery, which can basically store 15kw of electricity, and can support it for one day without wind. If the number of days it needs to be supported increases, you can double the battery.
Although your maximum power does not exceed 600w, it still It is recommended that you choose a 2kw inverter, after all, the difference is only a few dollars.
