生产过程控制中电磁干扰的产生与抑制

Produce and Inhibition of Electric and Magnetic Interference in Control of Production Process

在生产过程控制中人们经常要讨论的问题:如何使用好仪表控制设备,使其能够安全、可靠、稳定地工作,从而保证生产的安全、长周期运行,使企业的效益最大化。其中干扰是一个主要问题,它贯穿于设计、施工、生产运行的全过程,如果某个环节出现问题,将最终影响到仪表正常使用,众多实践证明在使用中解决干扰问题往往是最棘手的。因此,就生产过程控制系统中干扰产生的类型和如何消除或抑制干扰进行了论述。

The problem often discussed in production process control is how to use instrument and make it secure, reliable and stable, thereby to ensure production security, long-period operation. Reliability and stability of the device in production process is key problem,which can ensure production long period op- eration and make the benefit for the enterprise. Interference is key influence element. It exists in whole course of design,construct,production operate, and will affect normal use if some segments exist problem. Interference exile in using-process is troublesome. So the type of interference result in productionprocess and how to abate and eliminate it are introduced.
