Maintenance Measures for Long-term Outage of Diesel Generator

Diesel generator is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It has low fuel consumption, low emissions, low noise, advanced technology, reliable work, convenient maintenance, long service life, lightweight and portable, high emergency efficiency, and comprehensive cost. Low, has a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life.

In recent years, with technological advancement, as a high-quality choice for home emergency power supply and power supply for outdoor travel, diesel generators can provide limited power supply and can be easily replaced in places where they are used; they can be placed indoors in thunderstorms, but in some cases diesel power generation The engine needs to be used outdoors. In severe weather, lightning protection of the equipment will be involved. So what are the specific steps for lightning protection of diesel generators?

First of all, it is necessary to determine the lightning protection method of diesel generators mainly according to the size of the generator capacity, the strength of local lightning activities and the requirements for power supply reliability.

Theory and practice have proved that if the diesel generator is connected to the overhead transmission line through the transformer, as long as the transformer is reliably protected, there is generally no need to take lightning protection measures for the diesel generator. In mine areas, there is no overhead direct wiring. In order to prevent the lightning wave on the high voltage side of the transformer from endangering the insulation of the generator through the transformer, it is advisable to install a set of magnetic blower arresters on the outlet of the diesel generator.

Diesel generators directly connected to overhead power distribution lines must be protected against lightning, and different lightning protection measures should be taken for the insulation of diesel generators according to different conditions in accordance with the provisions of the national standard design code. The lightning arrester used to protect the high-voltage rotating electrical machine generally adopts a magnetic blown arrester, and the arrester should be close to the diesel generator. Under normal circumstances, the arrester can be installed at the outlet of the motor;

If there are no more than two diesel generators connected to each group of bus bars, or the capacity of a single unit does not exceed 500kw, and the distance from the arrester is no more than 50m, the arrester can also be installed on each group of bus bars as a direct-matching motor neutral. When the point can be led out and is not directly grounded, a magnetic blower or ordinary valve-type arrester should be installed on the neutral point. When using diesel generators outdoors, you must pay attention to lightning protection to ensure personal safety.

Many customers buy diesel generators as a backup power source and only use them several times a year. If the diesel generator is out of service for a long time without proper maintenance, it will cause the generator to fail to start when it needs to be used.
