卷簾門主要依靠變頻器來進行控制的，但是你知道關于變頻器的一些小知識嗎？下面就讓濟南電動卷簾門安裝維修人員來為您講解一番吧。

The roller shutter door is mainly controlled by the frequency converter, but do you know some small knowledge about the frequency converter? Let the installation and maintenance personnel of Jinan electric roller shutter door explain it for you.

使用異步開門器時，變頻器是安裝和使用快速卷簾門不可缺少的附件。通過變頻實現快速開關的效果，對于快速卷簾門日常操作的輔助功能非常重要。

When using the asynchronous door opener, the frequency converter is an indispensable accessory for installing and using the fast rolling shutter door. The effect of fast switching through frequency conversion is very important for the auxiliary function of daily operation of fast rolling shutter door.

所謂快速門逆變器，就是將工頻電源(50Hz或60Hz)轉換成各種頻率的交流電源，實現電機調速運行的裝置。

The so-called fast gate inverter is a device that converts the power frequency power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize the speed regulating operation of the motor.

門廠快速卷簾門使用的逆變器有很多種分類方法。其中，根據主電路的工作模式分為電流型逆變器和電壓型逆變器。

There are many kinds of classification methods for the inverter used in the fast rolling shutter door of the door factory. According to the working mode of the main circuit, it is divided into current type inverter and voltage type inverter.

控制逆變器和高載波頻率PWM控制逆變器；按工作原理可分為矢量控制逆變器、V/f控制逆變器和轉差頻率控制逆變器。按應用分類，可分為單相逆變器、三相逆變器、通用逆變器、高性能專用逆變器和高頻逆變器。

Control inverter and high carrier frequency PWM control inverter; According to the working principle, it can be divided into vector control inverter, V / F control inverter and slip frequency control inverter. According to application classification, it can be divided into single-phase inverter, three-phase inverter, general inverter, high-performance special inverter and high-frequency inverter.

目前各國使用的交流電源的電壓和頻率，無論是家用還是工廠用，都是400v/50hz或200v/60hz(50hz)。我們通常把固定電壓和頻率的交流電轉換成可變電壓或頻率的交流電的裝置稱為“變頻器”。

At present, the voltage and frequency of the AC power supply used in various countries are 400V / 50Hz or 200V / 60Hz (50Hz), whether it is for household or factory use. We usually call the device that converts the fixed voltage and frequency AC into variable voltage or frequency AC as "frequency converter".

為了產生可變的電壓和頻率，設備需要將電源的交流電轉換成直流電力(DC)。用于電機控制的變頻器可以改變電壓和頻率，以滿足快速卷簾門高速運行的需要。

In order to generate a variable voltage and frequency, the equipment needs to first convert the alternating current of the power supply into direct current power (DC). The frequency converter used for motor control can change the voltage and frequency to meet the needs of high-speed operation of the fast roller shutter door.
