In the use of electric vehicles, the use of battery electric locomotive is still relatively common. High efficiency and energy-saving technology and equipment is the most important one in the battery frequency conversion electric locomotives. At present, China's industrial power consumption is the main component of social power consumption, while the energy consumption of explosion-proof battery electric locomotives plays a major role in industrial power consumption. Therefore, the potential of motor energy conservation in the future is very significant Huge, let's understand together, what's the way to improve the operation efficiency of battery frequency conversion electric locomotive?
There are two ways to improve the operation efficiency of the battery inverter electric locomotive:
1. Improve the operation efficiency of the AC electric locomotive through the frequency converter;
2. Use efficient motor. Therefore, in terms of energy-saving equipment, the market scale of high-voltage inverter and high-efficiency motor cannot be underestimated.
66% of the total power generation in China is consumed by motors, and the operation efficiency of various motors is 10-20% lower than that of foreign advanced level. The total installed capacity of the motor is about 762 million kilowatts, 90% of which are AC motors, while the high-voltage motor accounts for about 50%, and nearly 70% of the load dragged by the high-voltage motor is fans, pumps and compressors, half of which are suitable for speed regulation.
As the battery frequency converter can adjust the motor speed in real time according to the actual needs, it can make the motor run at the most energy-saving speed, and can greatly reduce the power consumption during light load operation, thus significantly reducing the comprehensive power consumption of motor operation. Its energy-saving effect is obvious, the general power saving rate is 20% - 30%, and the maximum can even exceed 50%. The investment recovery period is generally 2 years left Right.
Compared with the ordinary motor, the energy consumption of the high-efficiency motor is reduced by about 20% on average by adopting high-quality materials and optimizing design, while the ultra-efficient motor consumes more than 30% less electric energy than the ordinary motor, and the price of the high-efficiency motor is 15% - 30% more expensive than the ordinary Y-series motor. But generally speaking, the investment of high-efficiency motor is higher than that of ordinary motor, which can be recovered within 2 years. In the whole life cycle, it can save power for enterprises.
