The development of future radio frequency technology
With the continuous development and improvement of industrial technology, frequency conversion technology has also been greatly improved. Frequency conversion technology has excellent power-saving performance, start-up characteristics and various protection functions. Not only help companies save energy, reduce costs, but also enhance security assurances.
Circuit Breaker is an electrical device used in an electrical panel that monitors and controls the amount of amperes (amps) being sent through the electrical wiring. Circuit breakers come in a variety of sizes. For instance, 10, 15 and 20 amp breakers are used for most power and lighting needs in the typical home. Some appliances and specialty items (washers, dryers, freezers, whirlpools, etc.) will require a larger circuit breaker to handle the electrical load required to run that appliance.

Frequency control is the best and most promising technology for speed control. The frequency converter is the main product for the three-phase asynchronous motor speed regulation in industrialized countries. Its main advantages are: good energy-saving effect, up to 55%; wide speed range, speed ratio up to 20:1; good start and braking performance, can achieve soft start, automatic smooth acceleration and deceleration and rapid braking; The protection function is perfect, and it can realize various protection modes such as overvoltage, undervoltage, overload, overcurrent, instant power failure, short circuit, stall, etc., and can realize fault judgment display; it is easy to use in the electronic computer system and can realize long-distance control.
The future high voltage variable frequency speed control technology will be developed in the following eight aspects, the main performance of which is: the pressure frequency converter will develop in the direction of high power, miniaturization, and light weight; the high voltage frequency converter will be directed to the direct device high voltage and multiple superposition ( The device is connected in series and the unit is connected in series; the new type of power semiconductor device with higher voltage and higher current will be used in high-voltage inverters; at this stage, IGBT, IGCT, SGCT will still play a major role, SCR, GTO Will exit the inverter market; speed sensorless vector control, flux control and direct torque control and other technology applications will mature; fully realized digitization and automation: parameter self-setting technology; process self-optimization technology; Diagnose technology; Apply 32-bit MCU, DSP and ASIC and other devices, to achieve high-precision frequency inverter, multi-function; related supporting industries are moving toward professional, large-scale development, social division of labor will be more apparent.
