High-voltage generator unit

High-voltage generator sets use high-quality domestic and foreign diesel engines as power, in accordance with the national standard "GB2820 Industrial Frequency Diesel Generator Sets General Technical Conditions", and referring to the International Electrotechnical Commission rotating machine standard "IEC34 - |", selecting high-quality generators produced domestically and internationally to produce high-voltage generator sets. With development, it is necessary to use multiple large-capacity generator sets to provide backup power. If traditional 380V generator sets are used for power supply, a large amount of power cables will be consumed and a large amount of cable channel space will be occupied. Moreover, multiple generator sets often cannot solve the problems of installation location, air intake and exhaust, exhaust, and noise reduction in the machine room, and the amount of cables and cable channels consumed is even greater. Therefore, in recent years, the industry has proposed the use of 10kV generator sets as backup power, which can significantly save power cables, reduce line losses, and save cable channels and civil engineering costs compared with conventional 380V generator sets. High-voltage generator sets are mainly divided into three types: 3kV, 6kV, and 10kV. These three voltage levels are called medium voltage in the power industry. Compared with the 380V low-voltage generator set, they can be called high voltage.
