苯酐包装生产线上称重仪表的选择

Weighing Instrument Options in Packaging Production Line of Phthalic Anhydride

本文以苯酐包装生产线为例阐述了称重仪表的选择。分析了电力系统中,由非线性负载谐波源所产生谐波的成因以及对电网供电质量的影响和危害,引入了暂态谐波和稳态谐波的概念。介绍了传统的谐波抑制方法和新型的谐波抑制方法,肯定了有源滤波器的是今后谐波抑制装置的主要发展方向。

The paper described the weighing instrument choice in packaging production line of phthalic anhydride.It analyzed in the power system,the generating cause of the nonlinear load harmonic harmonics and the power supply quality causes and effects and harms,it introduced the transient and steady-state harmonic concept.It introduced the traditional harmonic restrained methods and new methods of harmonic suppression.It confirmed active power filter is main direction of harmonic suppression device development in the future.
