IM33-11-HI/24VDC 图尔克安全栅/防爆

安全栅的主要功能就是限制安全场所的危险能量进入危险场所，及限制送往危险场所的电压和电流。齐纳管Z用于限制电压。当回路电压接近安全限压值时，齐纳管导通，使齐纳管两端的电压始终保持在安全限压值以下。电阻R用于限制电流。当电压被限制后，适当选择电阻值，可将回路电流限制在安全限流值以下。
————————————————————
本安系统除了要选择合适的安全栅外，使用的时候要注意以下几个方面：
一，要注意线缆和现场设备的容抗和感抗，本安防爆是系统防爆，除了安全栅需要达到所需的防爆等级外，线缆和现场设备的蓄能也是一个关键问题。特别是在参量认证替代系统认证后，工程商尤其要注意这个问题。
第二，要注意本安接地，齐纳安全栅需要本安接地，接地电阻应小于1。
第三，本安线缆与非本安线缆应分开敷设在不同的线槽里。并应有明显标识。
第四，更换时应注意断电。
