  發電機的分類有哪些?

What are the classifications of generators?

  發電機的分類方式通常有以下三種:

There are usually three classification methods for generators:

  按驅動動力分類

Classified by driving force

  發電機驅動動力的形式有多種,常見的的動力機有:

There are various forms of power driven by generators, and common power machines include:

  風力發電機就是依靠風力帶動發電機轉動,產生電流;這種發電機無需消耗額外能源,是一種無污染的發電機。

A wind turbine relies on wind power to drive the generator to rotate and generate current; This type of generator does not require additional energy consumption and is a pollution-free generator.

  水力發電機是利用水流的落差,產生動力,帶動發電機發電,也是利用綠色自然資源發電的設備,又稱水輪發電機。

A hydroelectric generator is a device that utilizes the drop of water flow to generate power, drives the generator to generate electricity, and also utilizes green natural resources for power generation, also known as a hydroelectric generator.

  燃油發電機是依靠柴油或汽油燃燒產生動力帶動發電機組的。遇到停電,就可啟動燃油發電機發電,以維持正常工作。

Fuel powered generators rely on diesel or gasoline combustion to generate power and drive the generator set. In the event of a power outage, the fuel powered generator can be started to generate electricity and maintain normal operation.

  按轉換的電能方式分類

Classified by the method of converting electrical energy

  按轉換的電能方式可分為交流發電機和直流發電機兩大類。

According to the conversion method of electrical energy, it can be divided into two categories: AC generators and DC generators.

  交流發電機又分為同步發電機和異步發電機兩種。同步發電機又分為隱極式同步發電機和凸極式同步發電機兩種。現代發電站中最常用的是同步發電機,異步發電機很少用。

AC generators are divided into two types: synchronous generators and asynchronous generators. Synchronous generators are divided into two types: hidden pole synchronous generators and salient pole synchronous generators. The most commonly used in modern power plants is synchronous generators, while asynchronous generators are rarely used.

  交流發電機組又可分為單相發電機和三相發電機兩種。三相發電機輸出電壓為380V,單相發電機輸出電壓為220V.

AC generator sets can be divided into two types: single-phase generators and three-phase generators. The output voltage of a three-phase generator is 380V, and the output voltage of a single-phase generator is 220V

  按勵磁方式分類

Classified by excitation method

  按勵磁方式可分為刷勵磁發電機和無刷勵磁發電機兩類

According to the excitation method, it can be divided into two types: brush excitation generators and brushless excitation generators

  有刷勵磁發電機的勵磁方式為他勵式,無刷勵磁發電機的勵磁方式為自勵式。他勵式式發電機的整流裝置是在發電機定子上,而自勵磁式發電機的整流裝置是在發電機組的轉子上。

The excitation method of a brushless excitation generator is separate excitation, while the excitation method of a brushless excitation generator is self excitation. The rectification device of a self-excited generator is located on the stator of the generator, while the rectification device of a self-excited generator is located on the rotor of the generator set.
