The frame number has nothing to do with the power, the frame number just indicates the installation size, the same frame number can have a variety of power, and the same power can also have a variety of frame numbers. The length of the core corresponding to the different frame numbers is also different, and the corresponding elevation is also different. There are different frame numbers and elevations for the same power, which is mainly for the convenience of equipment installation to adapt to different equipment and installation environments.
L=90 and 4 L=100 are different frame numbers, and the installation size of the two is different.

Generators are: active power, reactive power.
There are three types of power, active power P, reactive power Q and apparent power S.
The three power and power factor COS are a right-angle code high-power triangle: the two right-angled edges are active power and reactive power, and the hypotenuse is the apparent power.
Active power squared + reactive power squared = apparent power squared.
In a three-phase load, all three types of power are always present at the same time at any time
Apparent power s=
Active power p=
Reactive power q=
Power factor cos = p s
sinφ=q/s
Active power is used to do work.
Electrical energy is used to do work to be consumed, and they are converted into thermal energy, light energy, mechanical energy, or chemical energy, etc., which is called active power; Also known as average power. The instantaneous power of the AC current is not a constant value, the average value of the power in a cycle is called the active power, which refers to the power consumed in the resistive part of the circuit, which is represented by the letter P in watts.
Reactive power is the one that builds up the magnetic field and transmits active power.
In a circuit with an inductor or capacitor, the inductor or capacitor sends the stored magnetic field (or electric field) energy to the power supply in half a cycle, and exchanges energy with the power supply, without really consuming energy. Hope.

Generally, a gasoline generator needs about 2L of gasoline per hour, and the greater the power, the higher the fuel consumption. (The amount of diesel fuel consumed by generator sets with different output power, different engines and other relevant parameters is different.) )
Main advantages: Generators are usually composed of stator, rotor, end caps and bearings. The stator consists of a stator core, a wire-wrapped winding, a base, and other structural parts that hold these parts in place.
The rotor is composed of rotor core (or magnetic pole, magnetic choke) winding, guard ring, central ring, slip ring, fan and rotating shaft. The stator and rotor of the generator are connected and assembled by the bearing and end cover, so that the rotor can rotate in the stator.

The power of a generator refers to the amount of work done by an object in a unit of time, i.e., power is a physical quantity that describes how fast or slow the work is done.

Unit power calibration.
Generally, the diesel generator set supplied to the coarse household is a common unit, which can supply power to the load at rated power for 12 hours (including 1
hours of capacity to operate at 110 rated power). When the mains power failure is not too frequent and the power supply time is not long, the user can use the power stool to know the generator set that is set as a standby unit. It should run at an average of 80 maximum power for no more than 200 hours per year and no more than 25 hours per year at 100 maximum power.

The national standard stipulates that the rated power on the nameplate of the diesel engine is divided into the following four categories;
min power: that is, the maximum power of the diesel engine allowed to run for 15min. It may be overloaded in a short period of time and requires the calibrated power with acceleration performance, such as the nominal power of diesel engines such as automobiles and motorcycles.
h power: that is, the maximum effective power of the diesel engine allowed to run continuously for 1h. Such as the calibrated power of diesel engines such as wheeled tractors, locomotives, ships, etc.
H power: that is, the maximum effective power of the diesel engine allowed to run continuously for 12h, that is, the rated power that we often say. For example, the calibrated power of diesel engines for power station units and construction machinery.
4. Continuous power: that is, the maximum power of the diesel engine allowed to run continuously for a long time.

Calibration power: The national standard stipulates that the power calibration of internal combustion engines is divided into four types according to the use and use characteristics.
15min powerThe internal combustion engine allows continuous operation i5min maximum effective power. It is suitable for internal combustion engine power calibration for automobiles, ships, tanks and other purposes.
The maximum effective power of a 1h power internal combustion engine allows continuous operation for 1h. It is suitable for the power calibration of internal combustion engines for industrial tractors, construction machinery, diesel locomotives, ships and other purposes.
The 12h power internal combustion engine allows the maximum effective power of continuous operation for 12h. It is suitable for the power calibration of internal combustion engines for agricultural tractors, agricultural drainage and irrigation, diesel locomotives, inland river vessels, etc.
Continuous powerThe maximum effective power that an internal combustion engine allows for long-term continuous operation. It is suitable for the calibration of internal combustion engine power for agricultural drainage and irrigation, ocean-going ships and power stations.
The diesel engine power calibrated according to the Chinese national standard is called the rated power. However, the standard does not stipulate the relationship between the calibrated power and the ultimate power, so the calibrated power can only be reasonably determined through production practice.
The difference between the parameters and performance of high-voltage generator sets and low-voltage generator sets is mainly reflected in the generator part and the distribution system part. >>>More
1. The selection of the power of the diesel generator set must meet the working requirements of the unit, and the power of the generator set is not simply added to the power of all the electrical appliances, but also the starting mode of the electrical appliances. The general starting mode is divided into direct start and step-down start or frequency conversion start, the former starting current is about 6 times of the working current, and the instantaneous power will reach 6 times of the rated power; The starting current of the latter is about 3 times, and the instantaneous power is also 3 times the rated power. >>>More
It is necessary to depend on the ratio of inductive equipment (such as motors, transformers) and capacitive equipment ((pure resistive loads) in electrical equipment, because their power factors are very different, so the difference in active power that can be dragged is also large. The specific load is calculated on a case-by-case basis.
The main power of diesel generator set is also called continuous power or long-running power, in China, the main power is generally used to mark the diesel generator set, and the international standby power is used, also known as the maximum power to mark the diesel generator set, there are often manufacturers who do not serve in the market to use the maximum power as continuous power to introduce and sell the unit, forming many users to misunderstand these two concepts. >>>More
Comparison of imported and domestic.
1. Quality: The characteristics of the domestic machine are durable and can adapt to the use of the harsh environment, while the imported diesel engine has higher requirements for working conditions, and is generally used as a fire backup and other use environments are better, and it is more suitable to purchase when the number of uses is less. >>>More
