摘要
随着电气防爆技术的发展,必须建立与正压外壳防爆电气设备相配套的正压控制系统,而模块化设计缩短了正压控制系统的设计和制造周期。文中通过示意图及大量的计算公式,介绍了一种正压控制系统,并对正压控制系统和节流装置的设计作了介绍。
With the development of explosion protection electrical technology, it is necessary to adopt of pressurized control system in the Ex equipment with a pressurized enclosure. The application of modular design is shorten the period ha design and manufacturing for Ex＂p＂equipment. A pressurized control system is present with schematic diagrams and design formulas, as well as the throttling set in this paper.
