The application of Odeli frequency converter in the power industry
The Odeli frequency converter is mainly used in the transformation of power generation projects for the induced draft fan of the boiler, and the transformation of frequency converters with different power ranges of 5.5-220kw is applied. The boiler induced draft fan is the main part of the boiler combustion support. It is a power equipment that removes the high-temperature flue gas generated by the boiler combustion through water mill dust removal, electrostatic precipitator, and then discharged through the chimney. When the boiler is burning, the load changes. In order to ensure the relative stability of the negative pressure in the furnace hall, the oxygen content in the flue gas, and the corresponding temperature and pressure, it is necessary to adjust the suction air volume of the induced draft fan in a timely manner, and adjust the air volume by the opening of the baffle.
After the Odeli frequency conversion transformation, stable and efficient operation of the boiler fan has been achieved, meeting the peak shaving needs of the power plant and achieving good energy-saving and consumption reduction goals.
The energy-saving effect is very obvious, and the starting frequency is low, the speed is low, the current is small and stable. Implemented soft start, avoiding the impact of high current and torque on motors, cables, switches, and mechanical equipment when starting with power frequency in the past. Not only does it extend the lifespan of motors and other equipment, but it also reduces bearing wear and improves the reliability of safe power supply.

Application of Soft Starters in Hydroelectric Power Plants
In hydropower plants, a large number of mechanical equipment are mostly driven by AC asynchronous squirrel cage motors, such as pressure oil pumps. During the direct starting process of AC asynchronous squirrel cage motors, a starting current of 5-8 times the rated current of the motor will be generated. Excessive starting current seriously affects the service life of the motor and contactor; Meanwhile, due to the high starting torque, it increases the wear and additional maintenance of rotating components; In addition, when the power of the motor is high, it causes a significant voltage drop, which affects the safe and stable operation of the power supply in the factory. Especially in case of accidents, it may cause the accident to expand. Therefore, larger capacity motors should adopt step-down starting.
The soft starter has multiple built-in protection functions, such as stall and stall testing, phase balance, under load protection, under voltage protection, overvoltage protection, etc., which further protect the motor.
