mtl安全栅
MTL安全栅(MTL Safety Barrier)是一种用于防爆电气设备
的安全措施,可确保在爆炸危险环境中使用电气设备时的安全性。
MTL安全栅的主要功能是将非安全信号(非防爆区域)转换
为安全信号(防爆区域),从而保护设备和人员免受爆炸和火灾的威胁。
它可以用于防爆区域的仪表、开关、传感器等设备的安全隔离和防护。
MTL安全栅的工作原理是通过使用阻挡电流的方式,将输入
信号转换为安全的输出信号。
它通过限制电流和电压的传输,防止火花或电弧的形成,从而降低了爆炸的风险。
MTL安全栅一般由两个部分组成:输入模块和输出模块。
输
入模块将非安全信号输入,输出模块将转换后的安全信号输出。
这两个模块之间通过隔离电路实现电流和电压的隔离,并确保在非安全区域的故障不会传导到防爆区域。
MTL安全栅具有多种特点和优势,如可靠性高、安装简便、
体积小等。
它能够适应各种恶劣环境,如湿度、温度、振动等,并具有一定的耐腐蚀性能。
另外,MTL安全栅还能够进行自
我监测和故障检测,以确保设备的正常运行和安全性。
总之,MTL安全栅是一种重要的防爆电气设备,它能够有效
地保护设备和人员免受爆炸和火灾的威胁。
在危险环境中使用
MTL安全栅可以提高工作安全性和生产效率,为工业生产提供保障。
MTL安全栅的技术说明
MTL是世界著名本安仪表品牌,本安技术多年居领先地位,MTL仪器仪表(中国)有限公司(以下简称MTL)是MTL公司全球业务的一部分,多年来在中国所有的大型石化企业的装置大量应用,占主装置进口安全栅份额的70%以上。
尤其在近几年百万吨乙烯和千万吨炼油项目中90%均采用MTL安全栅,如兰州乙烯,茂名乙烯,赛科100万吨乙烯,福建100万吨乙烯一体化(含1000万吨炼油),海南1000万吨大炼油,青岛1000万吨大炼油,燕山石化1000万吨炼油改造,广石化800万吨炼油,武石化800万吨炼油。
在这些大项目中,均采用DCS与安全栅整体采购,这样可以减少工作界面与中间环节,便于项目管理,提高工程效率,这种模式也是国际上正在流行的采购模式,说明中国的工程建设当正在引入先进的国际化工程理念。
在本项目中MTL可以提供成熟的、有丰富应用经验的底板安装方案,这是一种世界上最先进的接线和安装方式,优点在于:
1.减少接线环节,减少故障点,提高系统可靠性。
2.节省机柜空间,减少机柜数量,利于控制室排布。
3.集成非常快捷,缩短开车调试周期。
4.便于系统运转后的日常维护和管理。
5.底板安装支持各家DCS厂商:Yokogawa, Honeywell, ABB, Foxboro, Triconex, Siemens,August Systems 。
6.已经取得IEC的SIL2认证,技术上亦可实现SIL3的安全标准。
为了更好地为中国的用户服务,MTL在上海和北京都配有丰富工程经验的高级应用工程师。
MTL引以自豪的是我们的生产效率和产品质量,但我们清醒地认识到在高速发展的工业领域,我们必须不断改进产品结构和提高质量,使MTL
永远站在本质安全领域的前列,才能更好地服务用户。
