generators: kinds, description, advantages and disadvantages
variety of devices:
- by type of fuel - petrol, diesel and gas;
- according to the number of phases - single-phase and three-phase;
- according to the control circuit and the presence of an armature - asynchronous and synchronous;
- a separate group includes inverter devices.
Advantages and disadvantages of individual devices
Gasoline units are small in size, power up 10 kW, lungs.
- pros: a little noisy, easy care, are inexpensive.
- Minuses: use a lot of fuel, resource to 3000 martyr, output voltage parameters fluctuate. Products are used as a backup power source during a power outage.
Power of diesel units up to 40 kW, resource to 40000 martyr. They consume fuel economically, very reliable, voltage parameters are stable. Products function without interruption. Used as a backup or main power source (for example on construction sites). Particularly popular diesel welding generator, which is widely used in the absence of external power supply.
- pros: power, stability, continuity.
- disadvantages: are expensive, makes noise during operation, difficult maintenance, hard to start at sub-zero temperatures. The devices are used as a constant source of energy.
The following gas mechanisms are produced: on liquefied gas, on network gas and universal. The latest models are used very often.
- pros: have a large resource, economical and environmentally friendly.
- disadvantages: may cause explosion hazard.
Generators are single-phase(220 AT) and three-phase(380 AT). They differ from each other. Models of the second type are chosen in that case, if there are three-phase consumers. They are expensive. If there are no three-phase consumers, then choose powerful single-phase models.
Asynchronous devices do not have windings. These are simple, reliable and cheap models. Minuses: hard to bear starting loads. Products are used for devices, which have active loads.
Synchronous devices can withstand starting loads very well, have windings on the armature. They are more expensive than previous units. The devices are suitable for welding machines and devices with reactive power. Minuses: brushes on the rotor.
Recently, inverter models have been in demand.. У них переменный сигнал преобразовывается в постоянный и наоборот. Параметры выходного тока становятся стабильными и качественными. Изделия применяют для питания телевизоров, компьютеров и средств охранной сигнализации.
Council! Перед выбором модели генератора изучите все данные о нем. Дизельные механизмы с мощностью 40 кВт подходят для постоянного и временного обеспечения различных объектов. А бензиновые изделия применяют для питания оборудования и электроинструментов.
