All about three-phase gasoline generators

The productivity of industrial enterprises and their functionality largely depend on a stable supply of electricity. In addition, in factories, the installed equipment is connected to 380 V. To ensure the normal operation process, you should supply 3-phase petrol generator... The output of the 3-phase unit is enough to satisfy the need for electricity and not stop the operation of the enterprise even in the event of an emergency power outage.

One of the main features of 3-phase power generators is the need for uniform current distribution between 3 phases. For example, when the total power of the unit is 15 kW, then a consumer with one phase with a total power of not more than 5 kW can be connected to each phase.

Key differences between 3-phase gas generators.

• Fuel type. Gasoline generators 380 V are a portable segment for construction sites, tire shops and other objects where 3-phase equipment is used. Diesel units 380 V are used at production facilities, in the form of a spare power source in cottage residential complexes. Gas units 380 V are currently the most environmentally friendly sources of power from 5 to 500 kW, covering the scope of use from summer cottages to shift workers' settlements in remote areas.
• On the frame or in the casing. 3-phase generators of frame design should be located in a room equipped with exhaust and supply ventilation and an exhaust system. Units in a casing are more expensive, but this pays off with the least labor-intensive outdoor installation, which implies the location of the gas generator on a horizontal platform.
• Automatic 3-phase units. At the request of the client, the power plant can be equipped with an ABP shield. This option performs constant monitoring of the main network and the start of the HU with further switching between the two sources of electricity.

Consider a company whose units have certainly earned the attention of both specialists and ordinary consumers.

The category of the most popular domestic units is headed by diesel and gasoline stations under the brand name "Vepr" from 2 to 320 kW, intended for use in everyday life and at work. Owners of cottages, small workshops, builders and oilmen have WAY-energy household electric generators with a capacity of 0.7 to 3.4 kW, and semi-professional ones with a capacity of 2-12 kW.

The favorites of the Russian market include Russian-Chinese devices of the Prorab and Svarog brands. Both brands are represented by diesel and gasoline models for home and industrial applications. Power of gas generators "Svarog" ranges from 2 kW for installations with one phase, up to 16 kW for 3-phase devices of the Ergomax series. Prorab units from 0.65 to 12 kW are extremely reliable and very comfortable in everyday life and business.

European units have the most impressive number on the market. The lion's share of them is characterized by high reliability, productivity and economy. Of those who have repeatedly hit the top ten world ratings, experts call the French SDMO units, German Hammer and Geko, Belgian Europower, Spanish Gesan, Aiken (England / China), FG Wilson (England), Huter (Germany / China). European is often referred to as Turkish Genpower units power from 0.9 to 16 kW.

French units SDMO have a power from 5.8 to 80 kW, and Huter (Germany / PRC) from 0.6 to 12 kW.

British diesel generators FG Wilson have a power from 5.5 to 1800 kW.

Aiken units of Anglo-Chinese assembly - 0.64 - 12 kW, and are classified as domestic and semi-professional.

Under the brand name Gesan (Spain) stations from 2.2 to 1650 kW are produced.

Belgian Europower made household diesel and gasoline installations up to 36 kW famous.

America's generator market is represented by brands Ranger, Mustang and Generac moreover, the first two brands are produced by the Americans together with China. Among the modifications Generac there are compact industrial and household units on liquid fuel, as well as on gas. Their power ranges from 2.6 to 13 kW.

As usual, high-tech and high-quality units are manufactured by Japan, South Korea and China. Among them stand out Hyundai (South Korea / China), Japanese Elemax, Hitachi, Yamaha, Honda, Japanese-Chinese Kipor units and new Chinese brand Green Field. Under the brand Green field household stations from 2.2 to 8 kW are produced to provide energy to household appliances, lighting, garden equipment, construction tools, as well as diesel generators from 14.5 to 85 kW.

Separately, it should be said about Japanese units, famous for their long life, unpretentiousness, stable performance and relatively low prices due to "native" components. This includes brands Hitachi, Yamaha, Honda, which traditionally occupy the 3 first places in demand in the market. Diesel, gas and petrol stations Honda are created on the basis of Honda engines with a power of 2 to 12 kW. Yamaha represented by household gas generators from 2 kW, and diesel generators up to 16 kW.

There are a number of key principles to follow when selecting a 3-phase gasoline generator.

• Price - high-quality three-phase gas generators cannot be cheap. In this case, inexpensive is a criterion for the use of low-quality materials, as well as the fact that soon the installation will begin to "crumble". A reliable gas generator is equipped with a gasoline engine and an electric generator, as well as additional automation and protection systems.
• Availability of automatic start (ATS). Individual consumers are not satisfied with the ATS supplied at the enterprise, in this situation it is possible to buy and install this unit on your own. When choosing a 3-phase gasoline generator with auto start, you need to pay attention to the time interval between the power outage and the start of the backup power source, as well as the quality of the voltage supply to the power grid.
• Required productivity... This aspect can include not only the choice of device power, but also the quality of the supplied voltage. Certain types of industrial equipment are susceptible to power surges. Inverter units are the most expensive types, but they guarantee the softest voltage supply. Before purchasing a suitable modification, you should consult an electrician and study the specifics of using the equipment.

The installation should be entrusted to professionals so that in the future the device will work without failures. The connection of the unit implies the connection of its wiring to the centralized network. Therefore, adherence to special rules is required during operation:

1. after completion of the installation, the generator is prepared for use;
2. check the oil level in the crankcase;
3. this operation is performed while the installation is on a flat plane;
4. as they are consumed, they fill in fuel;
5. if the generator is indoors, it must be ventilated during maintenance;
6. when refueling, it is forbidden to smoke, use an open flame;
7. the fuel is poured very carefully, not allowing leaks.
