2.1 主控、輔佐體系輸入/輸出繼電器以及操控繼電器的選用 跟著現(xiàn)代科技的高速開(kāi)展，控制系統(tǒng)、交換機(jī)、現(xiàn)場(chǎng)智能儀表等現(xiàn)代電氣、電子設(shè)備的集成度越來(lái)越高，運(yùn)轉(zhuǎn)速度也越來(lái)越快，但隨之而來(lái)的是器材抗沖擊才能卻越來(lái)越弱，鋼鐵行業(yè)是這些電氣設(shè)備的使用大戶，在曩昔的使用過(guò)程中，常常有一些設(shè)備因雷電、開(kāi)關(guān)電子脈沖等的沖擊而損壞，造成了很大的丟失。因而，防雷過(guò)電壓維護(hù)技術(shù)越來(lái)越遭到鋼鐵行業(yè)的注重。
2006年末，馬鋼新區(qū)項(xiàng)目中的燒結(jié)、料廠、第一座高爐等技術(shù)段順暢投產(chǎn)，第二座高爐于2007年3月投產(chǎn)，新區(qū)項(xiàng)目中其它技術(shù)段均于2007年9月份之前完結(jié)投產(chǎn)。在全部項(xiàng)目調(diào)試、投產(chǎn)運(yùn)轉(zhuǎn)過(guò)程中，PHEONIXCONTACT的商品，以其優(yōu)良的品質(zhì)、安穩(wěn)牢靠的功能，得到了客戶充分的必定，為馬鋼新區(qū)項(xiàng)目的順暢投產(chǎn)作出了重要貢獻(xiàn)。
