With the continuous development of industrial technology, the application of frequency converter is applicable to all walks of life. Today we will introduce to you the successful application of frequency converter in various fields. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), brake unit, drive unit, and detection unit micro-processing unit. The inverter regulates the voltage and frequency of the output power supply by the breaking of the internal IGBT.
Inverter is the application of frequency conversion technology and microelectronics technology, by changing the frequency of motor power supply to control the AC motor power control equipment. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), brake unit, drive unit, and detection unit micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed control. In addition, the inverter has many protection functions. , such as over-current, over-voltage, overload protection and so on. With the continuous improvement of industrial automation, inverters have also been widely used.
According to Tiantuo Quartet's years of industry experience, inverters can be used in 32 classical industries, such as air-conditioning load, crusher load, large furnace calciner load, compressor load, and rolling mill. Loads, Converter Loads, Hoist Loads, Roller Loads, Pump Loads, Cranes, Dump Truck Loads, Wire Drawing Machine Loads, Transport Vehicle Loads, Elevator Overhead Touring Loads, Feeder Loads, Stacker-reclaimer load, fan load, mixer load, spinner load, special power load, etc.
Here are the specific applications of these industries in specific analysis:
1、Application of frequency converter in air conditioning load
Office buildings, shopping malls, and some supermarkets and factories all have central air-conditioning. During the summer months, the power consumption is very high. In hot weather, the electricity consumption of air-conditioners in Beijing, Shanghai, and Shenzhen accounted for more than 40% of peak power. Therefore, using the frequency conversion device to drive the refrigeration pump, cold water pump, and fan of the air conditioning system is a very good energy-saving technology. At present, many companies specializing in air conditioning have emerged throughout the country. The main technology is frequency conversion and energy saving.
2. The inverter is applied to crusher load
Many crushers and ball mills are used in metallurgical mines and building materials, and the effects of such loads after frequency conversion are significant.
3, inverter used in large furnace calcining furnace load
Most large industrial rotary kilns (converters) such as metallurgy, building materials, and caustic soda used DC, commutator motors, slip motors, cascade speed control, or medium-frequency unit speed control. Because these speed control methods have slip rings or low efficiency, in recent years, many companies have adopted frequency conversion control and have excellent results.
