设计
SINAMICS G120C is a compact converter for control cabinet mounting in IP20 degree of protection where the Control Unit (CU) and Power Module (PM) function units are combined in one device.
The compact mechanical design and the high power density allow these devices to be installed in machine control enclosures and control cabinets for maximum space utilization. The SINAMICS G120C compact converter can be butt-mounted directly, without derating at temperatures up to 40 °C (104 °F).
SINAMICS G120C, frame size FSAA with BOP-2
SINAMICS G120C can be integrated into the widest range of applications, either using the integrated digital and analog inputs or via the integrated fieldbus interface (available in USS, Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP versions). Especially the product versions with integrated PROFIBUS/PROFINET interface make full integration into the Siemens TIA family possible, therefore allowing the advantages of the seamless TIA product family to be fully utilized. SINAMICS G120C devices are preset in the factory so that they can be immediay connected to PROFIBUS and/or PROFINET fieldbus systems without parameterization.
SINAMICS G120C is also equipped with the safety function STO (Safe Torque Off) as standard, which is used to safely stop drives. As a consequence, machine manufacturers can simply comply with current machinery directives with minimum associated costs.
SINAMICS G120C can control asynchronous (induction) motors in the power range from 0.37 kW up to 132 kW (0.5 hp to 200 hp). Reliable and efficient motor operation is achieved by using state-of-the-art IGBT technology combined with vector control. The extensive range of functions integrated in the SINAMICS G120C also offers a high degree of protection for the converter and motor.
Line-side components
Line reactors
Line reactors smooth the current drawn by the converter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC-link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the converter.
Recommended line-side power components
Standard fuses can be used for the SINAMICS G120C. These must be dimensioned to comply with local regulations. In this chapter, you will find recommended components such as fuses and circuit breakers in compliance with IEC and UL regulations.
DC link components
Braking resistors
Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are designed for use with the SINAMICS G120C. This has an integrated braking chopper (electronic switch).
Load-side power components
Output reactors
Output reactors reduce the rate of voltage rise (dv/dt) and the height of the current peaks, and enable longer motor cables to be connected.
Supplementary system components
Inligent Operator Panel IOP
Graphics-based, user-friendly and powerful operator panel for commissioning and diagnostics as well as local operator control and monitoring of SINAMICS G120C.
Basic Operator Panel BOP-2
A 2-line display to provide support when commissioning and troubleshooting the drive. The drive can be locally controlled.
Memory card
The parameter settings for an inverter can be stored on the SINAMICS SD memory card. When service is required, e.g. after the inverter has been replaced and the data have been downloaded from the memory card the drive system is immediay ready for use again. The associated memory card holder is integrated in the inverter.
PC inverter connection kit 2
For controlling and commissioning an inverter directly from a PC if the STARTER commissioning tool or SINAMICS Startdrive has been installed on the PC.

西门子S7-200 PLC在电磁感应加热造纸烘缸中的应用
“感应加热”是一种合适的加热方式，具有热效率高、加热均匀、安全等特点，在钢铁冶炼、汽车制造等行业已有成功应用。本文将“感应加热”应用到造纸烘缸设备的开发中，设计了一个小型试验纸机中频感应烘缸，并利用SIEMENS S7-200系列PLC产品，开发了一套成本低、控制精确、操作方便的控制系统。经过调试运行，电磁感应烘缸*可以满足原有生产工艺的要求，运行稳定，节能效果明显，可以作为传统烘缸的替代产品，有广阔的市场前景。
1 感应加热电源
1.1 感应加热电源原理
开发感应加热电磁烘缸，关键是开发稳定可靠的感应加热电源系统。目前各个领域投入使用的感应加热电源，主要结构大致相同，都是由如下的几部分组成：
(1)整流变换电路(AC-DC);
(2)逆变电路(DC-AC);
(3)谐振负载电路;
(4)电源保护及控制电路。
感应加热电源的原理图如图1所示。其中，整流变换电路将50 Hz工频市电转换为直流电;根据整流得到的直流电压大小是否可变，整流电路可以分为“可控整流”和“不可控整流”，其中“不可控整流”只需要采用大功率二极管作为整流元件即可，电路结构简单，可有效降低设备成本;整流后的直流电再经过逆变电路，变换成大小和方向都随时间变化的交流电，其频率和幅值可以通过逆变电路控制;按要求得到的交变电流加载到谐振负载电路上，在负载线圈上产生交变的磁场，从而在置于交变磁场中的金属器件表面产生涡流，完成能量的传递，达到加热金属器件的目的;“保护控制电路”起保护作用以及调节加热功率的大小。
1.2 串联谐振型感应电源
串联谐振型感应电源又称“电压型感应电源”，其主电路原理图如图2所示。A 区域部分为三相桥式不可控桥式整流电路，它将工频交流电整流成脉动的直流电ud;B为直流中间路，它由一个滤波电感和滤波储能电容组成，它把50Hz工频网络和中频网络隔开，电容很大，它两端基本上是平滑的直流电压u'd，此电压是在逆变电路C还没有工作前电容器就储能建立的电压，以便于启动逆变电路;C 为单相桥式串联逆变电路，它将直流电压u'd逆变为中频方波电压ud，并把它加到负载电路;负载电路D为电感器和电容器组成的串联振荡电路，它对工件进行感应加热。中频电压u'd中含有明的基波和谐波成份：接近谐振频率的基波电压加到串联振荡电路时，振荡电路呈高阻，比基波频率高几倍的谐波电压加到串联振荡电路时，振荡电路呈现很小的阻抗。所以方波电压加到串联振荡电路时，感应器负载电流ia实际上接近于正弦波。
1.3 逆变调功
逆变调功是整流部分不采用相控整流，而是用简单的不可控整流代替，整流输出电压不可控制，通过在逆变过程中改变频率或者相位角等办法来实现功率调节的方法。常见调功方法主要有脉冲频率调制法(PFM)、脉冲密度调制法(PDM)、脉冲宽度调制法(PWM)等。
PWM法是通过调节输出电压的脉冲宽度以及输出频率来实现功率调节的。由于改变脉动宽度时，脉冲的周期也变化，频率相应改变，为了区别于工作频率不变的移相PWM方法，也称这种方法为脉冲宽度与频率混合调制(PWM&PFM)方法。
一般的逆变器如DC-DC变换逆变器中，常用的移相PWM方法的工作频率是固定的，不需考虑负载在不同工作频率下的特性。而串联谐振感应加热电源要求其工作频率必须跟踪负载的谐振频率。在串联谐振感应加热电源使用移相PWM方法时，通常使某一桥臂的驱动脉冲信号与输出电流的相位保持*，另一桥臂驱动脉冲信号与输出电流的相位差则可以调节，通过改变两个桥臂开关器件的驱动信号之问的相位差，来改变输出电压有效值，以达到调节功率的目的。由于PWM&PFM 调功方式具有不可控整流、电路简单、成本较低、功率调节范围宽、控制电路实现较易、频率变化不大等优点，开发的电磁感应烘缸中将采用此种调功方式。
2 烘缸设计及PLC硬件
2.1 电磁烘缸的物理组构
在系统生产的过程中，烘缸设备是需要一直转动的，如何将电感线圈与转动的烘缸设备组合在一起，既满足线圈与烘缸设备之间传递能量的需要，又不影响烘缸的转动，生产过程中的引致等操作，在物理实现上还必须简单实用，这种线圈与烘缸的组合方式称为电磁烘缸的物理组构。
造纸烘缸主要由烘缸体、烘缸罩、以及变频电机和齿轮箱组成。与传统的油热烘缸和蒸汽烘缸不同，电磁烘缸体内部不需要通入加热介质，不需要封闭，只需要三根辐条支撑在内缸体表面即可。烘缸罩位于烘缸缸体的顶部，可以上下活动。当需要引纸时，通过控制箱上的按钮可以将烘缸罩抬起，此时电磁烘缸停止加热;当引纸操作完成，正常操作时候，放下烘缸罩，感应电路对烘缸加热。烘缸罩的抬升与降落采用手动方式，配置小型空气压缩机。利用上下行程开关，保证烘缸罩降落时与缸体表面有合适的间距。
2.2 造纸生产工艺流程
在造纸生产工艺流程中，纸浆过滤去水之后，形成薄薄的一层附着在传动带上。这些潮湿的纸浆先被传送到几个烘箱中，经初步的烘烤去掉一些水分。烘箱中自上而下吹入100℃以上的热空气，热风的温度可以调节。潮湿的纸浆薄层在热空气中一部分水分挥发，水蒸气随热风吹走，达到预烘干的目的。潮湿的纸张从烘箱中出来以后，再到表面温度1400℃左右的烘缸上烘烤，去掉剩余的大部分水分。烘缸表面的温度需要根据不同的纸张厚度和纸张材质，以及走纸的速度来上下调整。
本课题开发的造纸系统，在整个工艺流程中潮湿纸浆薄层成型后，附着在传送带上经过了三个烘箱。三个烘箱设备结构基本相同，采用的是电热烘箱。每个烘箱上部装有电热板，通入电流后，电热板发热，从顶部吹入的冷风被加热成热空气，吹到传送带上对纸浆薄层进行预干燥。使用标准的4～20mA电流信号来控制流经电热板的加热电流，从而实现对加热功率的控制，调节烘箱内的温度。
散热排湿及空气循环系统部为冷空气进风总管，由鼓风机向其中吹气。总管分为三个分管，经过几层电热板进入三个烘箱内。在分管的入口处，各有一个插片式挡板，改变挡板的插入深度，可以改变进风量。
冷空气被电热板加热后，热风对着潮湿纸张吹干去湿，与挥发的水蒸气混合，热风湿度增大，温度降低;三个烘箱内的湿风在烘箱底部经排湿口排出。排湿入口处也各装有一个插片式挡板，可以调节排出去的湿风流量，调节烘箱内的湿度。另外，在排湿口总管的出口处，安装有抽风机，吸出三个烘箱以及烘缸罩内的潮湿空气。经过烘箱后的潮湿空气，虽然温度有一定降低，但是仍然有相当部分的热量，全部排出不再利用从节能的角度看有些浪费。因此设计了潮湿热风的回流，在排湿总管上分出一部分重新进入进风总管，从而有效地提高了能源的利用率。回流进风量的多少，也通过一个插片式挡板来调节。
电磁烘缸是zui后一道造纸加热工序，经过预干燥之后的纸张，与高温的烘缸表面接触，除去剩余的水分，产生大量的水蒸气。由于水蒸气密度小于空气，会上升被烘缸罩收集。烘缸罩顶部也留有一排湿口，并与排湿总管相连。在排湿口抽风机的吸力下，顺利排出室外。
