卷帘门关于变频器的一些知识

卷帘门主要依靠变频器来进行控制的，但是你知道关于变频器的一些小知识吗？下面就让济南电动卷帘门安装维修人员来为您讲解一番吧。

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.

使用异步开门器时，变频器是安装和使用快速卷帘门不可缺少的附件。通过变频实现快速开关的效果，对于快速卷帘门日常操作的辅助功能非常重要。

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.

所谓快速门逆变器，就是将工频电源(50Hz或60Hz)转换成各种频率的交流电源，实现电机调速运行的装置。

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.

门厂快速卷帘门使用的逆变器有很多种分类方法。其中，根据主电路的工作模式分为电流型逆变器和电压型逆变器。

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.

控制逆变器和高载波频率PWM控制逆变器；按工作原理可分为矢量控制逆变器、V/f控制逆变器和转差频率控制逆变器。按应用分类，可分为单相逆变器、三相逆变器、通用逆变器、高性能专用逆变器和高频逆变器。

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.

目前各国使用的交流电源的电压和频率，无论是家用还是工厂用，都是400v/50hz或200v/60hz(50hz)。我们通常把固定电压和频率的交流电转换成可变电压或频率的交流电的装置称为“变频器”。

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".

为了产生可变的电压和频率，设备需要首先将电源的交流电转换成直流电力(DC)。用于电机控制的变频器可以改变电压和频率，以满足快速卷帘门高速运行的需要。

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.
