PLC变频器控制柜主要是有哪些应用?

发布时间:2024-02-26 来源://www.aqfitlab.com/ 浏览量:

变频器控制柜是由PLC控制变频器及外围设备所构成的一个系统,它具有显示,保护等功能,是对三相交流电动机(包括风机,泵)进行变频调速控制的交流拖动装置和装置。与传统的变频器控制柜相比显著的特点是能实现PID调节。

The frequency converter control cabinet is a system composed of PLC controlled frequency converters and peripheral equipment, which has functions such as display and protection. It is an AC drive device and energy-saving device for frequency conversion speed control of three-phase AC motors (including fans and pumps). The significant feature compared to traditional frequency converter control cabinets is the ability to achieve PID regulation.

Power switching and protection: The PLC frequency converter cabinet is equipped with a circuit breaker connected to the incoming power supply. In addition to completing the connection and disconnection of the circuit, it can also protect the circuit and frequency converter from short circuits and overloads. And the power can be cut off during maintenance.

启、停控制功能:PLC变频柜面板上会装人机界面,在此有变频启动,变频停止按钮,用于变频装置的运行控制。也可以在面板上安装按钮。

Start and stop control function: The PLC variable frequency cabinet panel will be equipped with a human-machine interface, where there are variable frequency start and stop buttons for controlling the operation of the variable frequency device. You can also install buttons on the panel.

PLC变频柜面板上设置电压表,电流表,频率表和各种指示灯如电源指示,报警指示,运行指示,工频指示,实现对变频器输入电压、输出电流、输出频率和各种工作状态的监测,这样看很直观。也可在人机界机中看到这些数据。

The PLC frequency conversion cabinet panel is equipped with a voltmeter, ammeter, frequency meter, and various indicator lights such as power indicator, alarm indicator, operation indicator, and power frequency indicator, to achieve monitoring of the input voltage, output current, output frequency, and various working states of the frequency converter, which is very intuitive. These data can also be seen in the human-machine interface.

通信功能:PLC变频器控制柜可与上位机联接,以实现遥控,遥测,遥信。

Communication function: The PLC frequency converter control cabinet can be connected to the upper computer to achieve remote control, telemetry, and remote signaling.

变频器控制柜典型应用可广泛应用于冶金、化工、石油、供水、矿山、建材、电机行业等泵类、风机、空气压缩机、轧钢机、注塑机、皮带运输机等。

Typical applications of frequency converter control cabinets can be widely used in pump, fan, air compressor, steel rolling machine, injection molding machine, belt conveyor, etc. in metallurgy, chemical industry, petroleum, water supply, mining, building materials, motor industry, etc.
