在技术改造项目中,变频器的投入和使用,节能效果是显而易见的。在新建项目中,变频器在风机、水泵中的应用也深入到钢铁、石油、化工各个行业,节能效果为大家所共识,是经济可持续发展的必然趋势。1西门子低压变频器(G120)的技术特点1)模块化。西门子SINAMICS G120低压变频器是1个由多种不同功能单元组成的模块化变频器。其主要单元:控制单元(CU),功率模块(PM)。控制单元可以按照几种不同的方式对功率模块和所接的电机进行控制和监控。它支持与本地或
In the technological transformation project, the frequency changer investment and the use, the energy conservation effect is obvious. In the newly-built project, the application of frequency converter in fans and pumps has also been deepened into various industries of steel, petroleum and chemical industry, and the energy-saving effect is the consensus of all people. It is an inevitable trend of economic sustainable development. 1 Siemens low-voltage inverter (G120) technical features 1) modular. Siemens SINAMICS G120 low-voltage inverter is a multi-functional modules composed of a variety of modular inverter. The main unit: control unit (CU), power module (PM). The control unit can control and monitor the power module and the connected motor in several different ways. It is supported with local or
