西门子G120C紧凑型变频器

SINAMICS G120C紧凑型变频器，在许多方面为同类变频器的设计树立了*。包括它紧凑的尺寸，便捷的快速调试，简单的面板操作，方便友好的维护以及丰富的集成功能都将成为新的标准。

SINAMICS G120C是专门为满足OEM用户对于高和节省空间的要求而设计的变频器，同时它还具有操作简单和功能丰富的特点。这个系列的变频器与同类相比相同的功率具有更小的尺寸，并且它安装快速，调试简便，以及它友好的用户接线方式和简单的调试工具都使它与众不同。集成众多功能：安全功能（STO,可通过端子或PROFIsafe），多种可选的通用的现场总线接口，以及用于参数拷贝的存储卡槽。

SINAMICS G120C 变频器包含三个不同的尺寸功率范围从0.55kW到18.5kW。为了提高能效，变频器集成了矢量控制实现能量的优化利用并自动降低了磁通。该系列的变频器是全集成自动化的组成部分，并且可选PROFIBUS, Modbus RTU,CAN以及USS 等通讯接口。操作控制和调试可以快速简单地采用PC机通过USB接口，或者采用BOP-2（基本操作面板）或IOP（智能操作面板）来实现。[2]

5日常维护

操作人员必须熟悉西门子变频器的基本工作原理、功能特点，具有电工操作常识。在对变频器日常维护之前，必须保证设备总电源全部切断；并且在变频器显示*消失的3-30分钟（根据变频器的功率）后再进行。应注意检查电网电压，改善变频器、电机及线路的周边环境，定期清除变频器内部灰尘，通过加强设备管理极大限度地降低变频器的故障率。

1、冷却风扇

变频器的功率模块是发热严重的器件，其连续工作所产生的热量必须要及时排出，一般风扇的寿命大约为20kh～40kh。按变频器连续运行折算为3～5年就要更换一次风扇，避免因散热不良引发故障。

2、滤波电容

中间电路滤波电容：又称电解电容，该电容的作用：滤除整流后的电压纹波，还在整流与逆变器之间起去耦作用，以消除相互干扰，还为电动机提供必要的无功功率，要承受极大的脉冲电流，所以使用寿命短，因其要在工作中储能，所以必须长期通电，它连续工作产生的热量加上变频器本身产生的热量都会加速其电解液的干涸，直接影响其容量的大小。正常情况下电容的使用寿命为5年。建议每年定期检查电容容量一次，一般其容量减少20%以上应更换。

3、防腐剂的使用

因一些公司的生产特性，各电气mcc室的腐蚀气体浓度过大，致使很多电气设备因腐蚀损坏（包括变频器）。

为了解决以上问题可安装一套空调系统，用正压新鲜风来改善环境条件。为减少腐蚀性气体对电路板上元器件的腐蚀，还可要求变频器生产厂家对线路板进行防腐加工，维修后也要喷涂防腐剂，有效地降低了变频器的故障率，提高了使用效率。

4、给变频器除尘：变频器根据使用环境的不同，应定期检查散热通道、及电路板中有无积累灰尘，一般每半年清理一次，至少也要一年清理一次，以确保变频器散热良好，使其避免因散热不良而引发故障。

在保养的同时要仔细检查变频器，定期送电，带电机工作在2hz 的低频约10分钟，以确保变频器工作正常。

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 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 immediately connected to PROFIBUS or PROFINET fieldbus systems without parameterization.

Wireless commissioning, operation and diagnostics via mobile device or laptop thanks to the optional web server module SINAMICS G120 Smart Access enabling user-friendly operation and easy access to the converter, even if this is installed in areas difficult to access.

With the optionally available SINAMICS CONNECT 300 IoT Gateway, connection to the Cloud MindSphere is possible.

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.
