Why use the inverter ? As the degree of industrial automation increased, the inverter has also been widely used. Now frequency control has been recognized by enterprises and users as the best way to speed. Not only can improve labor productivity, improve living environment, but also energy saving, lower production costs. The correct choice of universal inverter drive control system for the normal operation of the can be very crucial, we must first clear the purpose of using universal inverter, according to the type of production machinery , speed range, speed response and control accuracy, starting torque and other requirements , Fully understand the load characteristics driven by the drive, decide what function of general-purpose inverter constitutes a control system, and then decide which control method is the most suitable. The selected general-purpose inverter should not only meet the requirements of the production process, but also have reasonable technical and economic indicators. If the general inverter selection, system design and use of improper, often with the same frequency inverter can not operate properly, fail to achieve the desired goal, and even lead to equipment failure, resulting in unnecessary losses. In addition, in order to ensure long-term and reliable operation of general-purpose inverters, it is also very important to connect the inverter ground. 1, frequency changer function and the use Adjustable speed drive composed of inverter and AC motor is called inverter drive, and its functions and purposes are as follows. Which may be related to each other, in fact, no clear classification, see the table below, for reference purposes only. 2, the advantages of using the inverter (1) energy-saving frequency control As the use of frequency control, fan, pump the most obvious energy-saving load-saving rate of 20% to 60%, this is because the fan pump power consumption and speed of the third power of proportion, when the user needs The average flow rate is small, the fan, pump speed is low, the energy saving effect is very impressive. The traditional baffle and Famen flow control, power consumption changes little. Because of this kind of load, which accounts for about 20% ~ 30% of the total capacity of the AC motor, their energy saving is of great significance. For some constant torque load running at low speed, such as conveyor belts, frequency control can also save energy. In addition, the original energy-saving speed control methods (such as winding rotor motors, etc.), the original speed control mode is more complex, less efficient (such as planer, etc.), the use of frequency control, Energy-saving effect is also obvious. (2) frequency control in motor operation advantages Frequency control is very easy to achieve positive and negative motor. Only need to change the inverter internal inverter tube switching order, you can achieve the output commutation, there is no problem due to commutation and burned the motor properly. Frequency control system start mostly from low speed, lower frequency. Canada, deceleration time can be arbitrarily set, so Canada, deceleration time is relatively gentle, starting current is smaller, you can start and stop at a higher frequency. When the frequency control system is braking, the inverter can use its own brake circuit to dissipate the energy of the mechanical load on the braking resistor and also to the power supply grid. However, the dedicated accessory needs to be added back to the grid to make a large investment. In addition, the inverter also has a DC braking function. When braking is required, the inverter adds a DC voltage to the motor to perform braking. There is no need to add a brake control circuit. (3) to improve the level of technology and product quality for the purpose of the application In addition to the frequency of fan speed, pump load on the application, but also can be widely used in conveying, winding, lifting, extrusion, machine tools and other mechanical equipment control. It can improve the peculiar product yield, extend the normal working period and service life of the equipment, simplify the operation and control system, and some even change the original technical specification, so as to improve the control level of the whole equipment. The above describes the purpose and advantages of using the inverter, I believe you have understood. Therefore, the use of frequency control on the user can according to their own actual process requirements and use of different occasions to choose different types of converter.
