How much power is generally required for a small household generator

The generator power 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, and the sum is 1400w 1400 times 3 = equal to the power of the generator).

The selection of a generator should be considered from the following points:

Step 1: 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, because a starting current should also be considered. When the electrical equipment is started, it is necessary to overcome the inertia to do work, and the starting current is generally 2-7 times of the actual current.

Step 2: Choose the diesel engine brand of the generator, know the starting current to determine how big the generator to use, and the performance indicators of the generator, the diesel engine accounts for a considerable proportion, because the power of the generator is the diesel engine, the diesel engine is full of power, easy to maintain, and the failure rate. Low.

Small wind turbines for home! The maximum power is 5kw, and you don't have to pay for electricity when you install one at the door!

How much power is generally required for small household generators depends on the electricity consumption, which should be calculated according to the actual electricity consumption.

Small household generators have small power, small size, small vibration, low noise, good quality and low price, and what kind of unit is needed to be selected according to the specific work needs.

Generally, 5kw is enough for household generators, and 2kw is enough if some electrical appliances can be reduced.

The specific calculation method according to the commonly used electrical appliances is as follows:

1.Common household appliance grade power:

Microwave oven 600---1500 watts.

Rice cooker 500---1700 watts.

Induction cooker 300---1800 watts.

The power of conventional diesel generators is 3kw - 2000kw!

No matter how big it is, it will be a heavy oil generator, weighing between 1,000 kilowatts and 75 trillion, and there are very few markets! If it's too big, you might as well build a power plant!

There are many types of generator sets, including gasoline generator sets, diesel generator sets, gas generator sets, wind turbine generator sets, hydro generator sets, etc. The minimum and maximum power of all types of units are different.

When selecting a generator set, users can choose the appropriate unit type, unit brand, unit power and unit configuration according to specific work needs and environmental requirements.

Large generator sets have a large power, generally referring to generator sets above 500kw. What brand, configuration and how much power unit the user needs can be selected according to the specific work needs.

There are many brands of large-scale generator sets, but users should pay attention to which industry the generator sets are used in? Is it a common power supply or an emergency backup power supply? What is the environment in which the unit is used, and whether the unit is used in the alpine region!

How much power is required for the unit and so on all affect the choice of unit brand. Like Cummins, Perkins, Yuchai, etc. are all good unit brands. Users can choose the right unit according to their needs and budget.

Specific matters should be communicated with the manufacturer.

The power of the unit should be selected according to the specific work needs, and whether the unit configuration needs to move the trailer and the silent box should also be selected according to the specific work needs, so that the selected unit can meet the work requirements.

At present, it is 750,000 kilowatts in China.

Household generators generally choose small generator sets, can be purchased according to the situation of household appliances at home, small generator sets are divided into gasoline generators and diesel generators, power optional: 3kw 5kw 6kw 7kw 8kw 9kw 10kw, etc., generally speaking, 5kw units can meet the use of power outages, if there are many household appliances, larger units can be purchased according to the situation.

Household generators generally buy 5kw units on it, when there is no electricity, you can spare power supply, gasoline generators and diesel generators can be selected, gasoline generators are lighter, diesel generators are more bulky, but the performance of diesel generators is better than gasoline generators, the service life is long, diesel generators are also a little more expensive than gasoline generators, normally domestic 5kw gasoline generators are about 2500 yuan, 5kw diesel generators are about 3500 yuan.

The general power of diesel generator sets is from 8 to 2000kw, and the brands of diesel generators include Cummins generators, Perkins generators, Volvo generators, Yanan generators, Yuchai generators, Weichai generators, Shangchai generators and other brands. Generally, diesel generators include stationary generators, mobile generators, silent generators, containerized generators and other styles.

Application fields of diesel generator sets.

1. Mines. The diesel generator set can be fixed on the foundation as a whole, positioned for use, or installed on a trailer for mobile use. Therefore, it is widely used in mines.

2. Marine and port.

Large ports have a large number of ships calling at each day, and the powerful diesel engines on board the ships must run continuously to keep the ship's equipment and support systems running.

3. Field construction sites.

Due to its small size, flexibility, lightness, complete facilities, easy operation and maintenance, it is widely used in field construction sites and other departments as a backup power supply or temporary power supply.

Fourth, municipal machinery.

Yanan Motor Tips: Diesel engines are widely used due to their high thermal efficiency. Off-highway diesel engines are the main body of the off-highway engine market, mainly used in agricultural machinery (such as tractors), construction machinery (such as excavators, loaders, bulldozers), material handling machinery (such as forklifts) and multi-purpose equipment (such as generator sets, pumps), etc.

5. Building construction.

The high-performance and stable generator set adopts a low-noise design to ensure that the replacement power system must be able to provide power immediately in the event of a mains power outage. Support the normal operation of all types of buildings and facilities around the world.

Sixth, special for breeding.

Farms are generally built in relatively remote places, and electricity is inconvenient, so generators are a must-have magic weapon for major farms. Aquaculture is an industry that uses more generator sets.

Generally, 5kw of household generators is enough, and 2kw is enough if some electrical appliances can be reduced. The specific calculation method according to the commonly used electrical appliances is as follows:1

Common household appliance level power: microwave oven 600---1500 watt rice cooker, 500 --- 1700 watt induction cooker, 300 --- 1800 watt electric wok, 800 --- 2000 watt electric water heater, 800 --- 2000 watt refrigerator, 70---250 watt electric heater, 800 --- 2500 watt electric oven, 800 --- 2000 watt sterilizer, 600 --- 800 watt electric iron, 500 --- 2000 watt air conditioner, 600 --- 5000 watt air conditioner 1000w microwave oven 1000w electric stove 1000w electric water heater 1000w vacuum cleaner 800w hair dryer 500w electric iron 500w washing machine 500w TV 200w computer 200w range hood 140w electric fan 100w flashlight lighting 50-100w2, power failure must be used electrical power calculation refrigerator 250w TV 200w computer 200w lighting 50-100w starting battery box is a type of compressor, and the starting current is calculated according to the times. Therefore, the power of the generator for the refrigerator is 250*, therefore, the minimum power of the generator for home use = 200 + 200 + 100 + 625 = 1125w, leaving part of the spare power, so the 2kw generator is enough! 3. Calculation of the power of commonly used electrical appliancesSome homes may add air conditioners, electric water heaters and other equipment on the basis of necessary electrical appliances

Because the air conditioner is a type of compressor, the starting current of the air conditioner is also calculated according to the multiple, and a 1000W air conditioner needs 2500W generator power. Coupled with the 1000w power of the electric water heater, plus the power of the original necessary electrical appliances 2000w, the generator used in the commonly used household appliances is 1125w + 1000w + 2500w = 4625w, and the backup 5kw generator is enough for Zhengzhenfen in the remaining department!

Power: generator rated speed 6000r; Rated voltage 12V or 24V; The hot state output current at the rated speed is the rated current. Generally, it consumes about 1900w.

The car generator is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idle), and at the same time charge the battery.

On the basis of the three-phase winding of the ordinary alternator, the number of winding turns is increased and the terminal is drawn out, and a set of three-phase bridge rectifier is added. At low speeds, it is output in series by the original winding and additional winding, and at higher speeds, it is only output by the original three-phase winding.

The working principle of the integral alternator: when the external circuit energizes the excitation winding through the brush, a magnetic field is generated, so that the claw pole is magnetized into the N pole and the S pole. When the rotor rotates, the magnetic flux changes alternately in the stator winding, and according to the principle of electromagnetic induction, it can be seen that the alternating induced electric turbulence potential is generated in the three-phase winding of the stator.

This is how the alternator generates electricity.

The generators have a wide range of power ranging from 8kW to 3000kW.

Generator refers to the mechanical equipment that converts other forms of energy into electrical energy, which is driven by water turbines, steam turbines, diesel engines or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy.

Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are all based on the laws of electromagnetic induction and electromagnetic forces. Therefore, the general principles of its construction are:

Magnetic circuits and circuits that use appropriate magnetic and conductive materials to generate electromagnetic power and achieve the purpose of energy conversion.

Whether it is a diesel generator or a gasoline generator, each cylinder works in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate.

The generator power is 30kw-2000kw in size, and the general large-scale power is more than 500kw, and users can choose the right generator set according to their needs.

The generators have a wide range of power ranging from 8kW to 3000kW. Regarding what is the power of the large generator set you said, this cannot give an exact definition, it can only be a relative value.

For general users, a 200kW generator set may be considered a high-power unit, but for oilfield development users, an 800kW generator set may be considered a high-power unit.

Therefore, it is enough to make the right choice according to your immediate needs.

If it is large, it is generally more than 40 kW, large can be up to thousands of kW, and there are 6000MW.

Large generator sets have a wide power range, and generator sets above 500ke are called large generator sets. How much power the user needs must be selected according to the specific work needs.

There are many brands of large generator sets, such as Yuchai, Cummins, Perkins, etc. The right unit brand can be selected according to various aspects such as budget.

In order to ensure the quality of the unit, it is necessary to choose from a regular manufacturer.

Available from 30 kilowatts to 2000 kilowatts!

2000 kilowatts are very large in the industry.

Generally, the power of diesel generators ranges from 5kw to 2000kw, and the power of diesel generator sets should be selected according to the needs.

Gasoline power generation power is very wide from 1kw to 60kw, and there are very few 60kw gasoline generators in the market.
