The main oil tank 1 and the spare oil tank are arranged outside the generator set 2. A tank pump 12 is arranged inside the main oil tank 1. An oil delivery pipe 13 is arranged at the output end of the tank pump 12. The other end of the oil delivery pipe 13 is connected to the generator set 2. A return oil pipe 14 is also arranged between the main oil tank 1 and the generator.

[0027] An oil replenishment pump 35 is provided inside the standby oil tank 3, and an oil replenishment pipe 7 is provided at the output end of the oil replenishment pump 35. The other end of the oil replenishment pipe 7 extends out of the standby oil tank 3 and is connected to the main oil tank 1.

[0028] A heating device is also provided outside the generator set 2 , and the heating device is used to heat the spare oil tank 3 .

[0029] The heating device comprises a negative pressure fan 4, which is fixed on the side wall of the generator set 2, and an air suction hood 5 is provided at the output end of the negative pressure fan 4;
