    變頻器的工作原理是怎么樣的?他的功能和應用有哪些?

    相信很多朋友對什么是變頻器一直不是很清楚。今天專業變頻器廠家邦瑞機電的沈工程師。就帶大家了解一下變頻器的工作原理具體是怎么樣的。
    I believe that many friends have not been very clear about what inverter is. Today, engineer Shen from Bongrui. Let's take a look at the working principle of the frequency converter.
     
    首先簡單的說呢。變頻器的主要作用就是將交流電經過電容器濾波逆變為直流電,然后再轉換所需要的電流頻率以提供給設備工作使用。一般是由中央芯片中心輸出信號通過驅動電路,控制輸出模塊輸出三相交流電。一般的直流電源大多是由交流電源通過變壓器變壓,整流濾波后得到的。很多人會好奇為什么變頻器使用量和使用范圍這么廣?要知道交流電源在人們使用電源中占總使用電源的95%左右。
    First of all, let's make it simple. The main function of frequency converter is to invert alternating current into dc current through capacitor filtering, and then convert the required current frequency to provide equipment for use. Generally by the central chip center output signal through the drive circuit, control output module output three-phase ac. The general DC power supply is mostly obtained by ac power supply through transformer transformer, rectification and filtering. Many people will be curious why frequency converter usage and use so wide range? We should know that ac power supply accounts for about 95% of the total power supply in people's use.
    變頻器的工作原理是怎么樣的?
     
    變頻器的作用:
    1,調整電機加減速時間長短和電機運行力矩大小。另外,變頻器還有很多的保護功能。如濾波、逆變、過流、過壓、過載保護等等。隨著工業自動化程度的不斷提高,變頻器也得到了非常廣泛的應用。
     
    Function of frequency converter: adjust motor acceleration and deceleration time and motor running torque size. In addition, the frequency converter has many protection functions. Such as filtering, inverter, overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency converter has been widely used.
     
    2,變頻器的作用:變頻器起到變頻節能。變頻器調整輸出電源的電壓和頻率,根據電機的實際需要來提供其所需要的電源電壓,進而達到節能、調速的目的
    2, the role of frequency converter: frequency converter to energy saving. The frequency converter adjusts the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation
    變頻器的功能和應用有哪些?
    變頻器的應用領域
    1,電氣伺服傳動領域  在要求速度控制和位置控制的場合,特種電機的應用越來越廣泛。開關磁阻電動機、永磁無刷直流電動機、步進電動機、永磁交流伺服電動機、永磁直流電動機等都已在數控機床、工業電氣自動化等方面。
    Frequency converter application field
    1. In the field of electric servo drive, the application of special motors is more and more widely in the occasions requiring speed control and position control (servo). Switched reluctance motor, permanent magnet brushless DC motor, stepper motor, permanent magnet AC servo motor, permanent magnet DC motor and so on have been in CNC machine tools, industrial electrical automation
     
    2,變頻器在自動化系統中應用非常廣泛。石油輸油泵、電潛泵,鋼鐵軋機、風機泵等。冶金行業、自動送料建筑、礦業設備,交通運輸領域,造紙業,電子制造業等領域都是必備設備組件。
    2. Frequency converters are widely used in automation systems. Oil pump, electric submersible pump, steel mill, fan pump, etc. Metallurgical industry, automatic feeding construction, mining equipment, transportation, paper industry, electronic manufacturing and other fields are essential equipment components.
     
    3,家用電器領域 ,據有關數據統計顯示:一般家庭中約使用 50~100 臺特種電機。如目前流行的高效節能變頻空調和冰箱就采用永磁無刷直流電動機驅動其壓縮機及風扇。洗衣機采用低噪聲多極扁平永磁無刷直流電動機,可省去原有的機械減速器而直接驅動滾筒,實現無級調速,是目前洗衣機中的高檔產品。吸塵器中采用永磁無刷直流電動機替代原用的單相串勵電動機,具有體積小、效率高、噪聲低、壽命長等優點。 
    3. In the field of household appliances, about 50~100 special motors are used in the average family. For example, the current popular high efficiency and energy saving frequency conversion air conditioning and refrigerator use permanent magnet brushless DC motor to drive its compressor and fan. The washing machine adopts low-noise multi-pole flat permanent magnet brushless DC motor, which can directly drive the drum without the original mechanical reducer and realize stepless speed regulation. It is a high-grade product in the current washing machine. Permanent magnet brushless DC motor is used in vacuum cleaner instead of single-phase series motor, which has the advantages of small volume, high efficiency, low noise and long service life.
    4,實現電機軟啟動。保護點擊設備安全運行
    4, achieve motor soft start. Protect click devices for safe operation
     
    5,特殊領域。比如各種飛行器、探測器、自動化裝備、醫療設備等使用的電機多為特種電機或新型電機。
     
    5. Special fields. For example, all kinds of aircraft, detectors, automation equipment, medical equipment and other motor used for special motor or new motor
