There are requirements regarding the quality of water used for cooling generators. For example, in power plants, the water used for cooling generators is chemically treated and the different ion contents cannot exceed the standards. You said to use distilled water, then you need to ensure that the water quality is not contaminated during the replenishment process and the water quality must meet the standards. Otherwise, it cannot be used!
Generators are generally classified in the following three ways:
1. Classification according to the electrical energy conversion method
According to the electrical energy conversion method. , it can be divided into AC power generation. There are two categories: machine and DC generator.
Alternator is divided into two types: synchronous generator and asynchronous generator. Synchronous generatorsones are divided into two types: hidden pole synchronous generators and salient pole synchronous generators. Synchronous generators are most often used in modern power plants and asynchronous generators are rarely used.
AC generators can be divided into two types: single-phase generators and three-phase generators. The output voltage of the three-phase generator is 380 V, and the output voltage of the single-phase generator is 220 V.
2. Classification according to the method of excitation
According to excitation. method, it can be divided into brush excitation generator and non-excitation generator. There are two types of brush excitation generators
The excitation mode of brush excitation generators is excited separately, while the excitation mode of brushless excitation generators. is excited by himself. The rectifier device of the self-excited generatorThe rectifier device is located on the generator stator, while the self-excited generator rectifier device is located on the generator rotor.
3. Classification by motive power
There are many forms of generator motive power:
(1) Wind turbine
.Wind turbines rely on wind energy to turn the generator and generate power; this generator does not consume extra energy and is a pollution-free generator;
(2) Hydropower generation machine
The hydro generator uses the water flow drop to generate energy to drive a generator to produce electricity. It is also a device that uses green natural resources to produce electricity.
The fuel generator relies on the combustion of diesel or gasoline to generate the energy needed to drive the generator set. Lhe use of a small fuel generator can play an emergency role. In the event of a power outage, the fuel generator can be started to generate electricity to maintain normal operation.
