The generator set is a complete set of mechanical equipment that converts other forms of energy into electric energy. It has low oil consumption, low emissions, low noise, advanced technology, reliable work, convenient maintenance, long service life, lightweight portability, high emergency efficiency, and low comprehensive cost. It is widely used in industrial and agricultural production, national defense, science and technology and daily life.
In recent years, with the progress of technology, as the choice of household emergency power supply and outdoor travel power supply, the power supply range of the generator set itself is limited, and the place of use can be easily replaced; In thunderstorm weather, the generator set can be placed indoors, but sometimes it needs to be used outdoors. In case of bad weather, the lightning protection of the equipment will be involved. What specific steps should be taken for the lightning protection of the generator set?
Firstly, it is necessary to determine the lightning protection mode of the generator set 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 as long as the transformer is reliably protected for the generator set connected to the overhead transmission line through the transformer, it is generally unnecessary to take lightning protection measures for the generator set. In the lightning prone area, for the particularly important generator set without overhead direct wiring, in order to prevent the lightning wave at the high voltage side of the transformer from passing through the transformer and endangering the insulation of the generator, a group of magnetic blow arresters should be installed on the outgoing line of the generator.
For lightning protection of generator units directly connected with overhead distribution lines, different lightning protection measures shall be taken for generator unit insulation according to different conditions according to the provisions of national standard design specifications. The lightning arrester used to protect high-voltage rotating motor generally adopts magnetic blowing lightning arrester, which should be close to the generator set. In general, the lightning arrester can be installed at the outlet of the motor;
If no more than two generators are connected to each group of buses, or the single unit capacity is no more than 500kw, and the distance from the arrester is no more than 50m, the arrester can also be installed on each group of buses. When the neutral point of the direct distribution motor can be led out and is not directly grounded, the magnetic blow or ordinary valve type arrester should be installed on the neutral point. When using generator set outdoors, pay attention to lightning protection to ensure personal safety.
Many customers buy diesel generator sets as standby power supply, which can only be used several times a year. If the diesel generator set is shut down for a long time without proper maintenance, it will be found that the generator cannot be started when it is needed. So what should we pay attention to when the diesel generator set is in a long-term shutdown state?
1、 Before sealing
1. After the primary diesel generator set is used, drain the lubricating oil of the diesel generator set in the hot state, including the oil in the oil filter. As the coolant has rust prevention function, it does not need to be drained. Fill the crankcase with qualified sealing oil of specified capacity, start the diesel generator set to idle speed, run for 1-1.5 min and then stop the engine, and then drain the sealing oil from the oil pan. The sealing oil inside the engine is the dehydrated CF grade 15W/40 lubricating oil.
2. Clean the surface of the diesel generator set, check that there is no visible dirt, oil stain, rust, water stain, etc., and then dry it with compressed air; Use a brush to evenly apply the antirust oil on the machined surface of all the metal surfaces of the diesel generator set (that is, the unpainted machined surface); Note that the surface of rubber parts, plastic parts and fiber fabric parts shall not be coated with antirust oil or contacted with antirust oil.
Note: certain rust prevention measures shall be taken for the surface of accessory drive pulley.
FD615 dehydrated antirust oil or antirust oil meeting the following performance requirements is recommended for engine external storage.
3. Disconnect the battery connecting wire, clean the terminal, apply a thin layer of grease to charge the battery.
4. Slack the drive belt
5. All exposed air pipes, water pipes or oil pipe orifices shall be sealed or wrapped with moisture-proof paper or vapor phase rust proof paper or polyethylene plastic film tape, and the entire air filter shall also be sealed or wrapped with moisture-proof paper.
2、 Saving period
Charge the battery every month. Check the liquid level of the battery, add it if necessary, and then charge it. Turn the crankshaft 3-4 times a month with the turning tool.
