Portable generators are great for recharging. According to relevant content surveys, there are many disadvantages of using gasoline for portable generators, such as: it is noisy when generating electricity and it feels like you are camping at a construction site. Not only is it large and difficult to store, but it is also difficult to store. It's also difficult to buy and transport gasoline, while rechargeable generators don't have that many disadvantages, so portable generators are better for charging.
Is it better to use a gasoline generator or a diesel generator at home?
The classification of generators includes:
The generators are divided into: DC generators and alternator; the alternator is divided into: synchronous generator and asynchronous generator (rarely used); alternator can also be divided into mo generatorsingle-phase and three-phase generator;
There are many types of generators. In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators.
In terms of production methods, they are divided into steam turbine generators, hydraulic generators, diesel generators, gasoline generators, etc. In terms of energy, it is divided into thermal generators, hydraulic generators, etc.
Detailed information:
1. Operating characteristics:
The performance of synchronous generators is mainly characterized by no-load characteristics and on-load operating characteristics. These features provide an important basis for users to choose generators.
2. No-load characteristics:
When the generator is not connected to a load, the armature current is zero, which is called no-load operation. At this time, the three-phase winding of the motor stator only has the no-load electromotive force E0 (three-phase symmetry) induced by the excitation current If, and its size increases with the increase of If. However, due to the saturation phenomenon in the core of the motor magnetic circuit, the two are not proportional. The curve reflecting the relationship between the no-load electromotive force E0 and the excitation current If is called the no-load characteristic of the synchronous generator.
3. Armature Reaction:
When the generator is connected to a symmetrical load, the three-phase current in the armature winding will produce another rotating magnetic field, called the armature. reaction magnetic field. Its speed is exactly equal to the speed of the rotor and the two rotate synchronously.
The armature reaction magnetic field andthe excitation magnetic field of the rotor of the synchronous generator can be approximately considered to be distributed according to the sinusoidal law. The spatial phase difference between them depends on the temporal phase difference between the no-load electromotive force E0 and the armature current I. The armature reaction magnetic field is also related to the charge state.
When the generator load is inductive, the armature reaction magnetic field acts as a demagnetizer, which will cause the generator voltage to decrease; when the load is capacitive, the armature reaction magnetic field acts as; a magnetizer. This will increase the output voltage of the generator.

Hello, it is recommended to choose a gasoline generator for domestic use of generators. The first reason is that the gasoline generator must be. small in size and does not take up spaceace. Easy to move; the second reason is that the noise of gasoline generators is lower than that of diesel generators;The third reason is that the general power of about 5 kilowatts is enough for home use, and it is more cost-effective to choose the gasoline with less chance of use. I hope that will be the case. useful for you.
