SB70P系列岸電電源控制系統(tǒng)針對(duì)岸電電源客戶需求定制開發(fā),滿足岸電電源系統(tǒng)供電要求。在樓宇自動(dòng)化領(lǐng)域,電力供應(yīng)的廣泛運(yùn)用常常伴隨嚴(yán)格的技術(shù)要求。電源在建筑物中應(yīng)用環(huán)境通常很惡劣。雷暴會(huì)造成電源供應(yīng)電壓的強(qiáng)烈瞬變,尤其是在高層和高塔建筑中。因此,對(duì)電源輸入變換器進(jìn)行穩(wěn)健性的電氣設(shè)計(jì)是至關(guān)重要的。在極端情況下,還會(huì)運(yùn)用電涌保護(hù)器保護(hù)電源輸入。小體積、低發(fā)熱
在建筑中,電力供應(yīng)的安裝空間通常是有限的,例如懸掛式天花板。普爾世電源內(nèi)部結(jié)構(gòu)緊湊的同時(shí)具備超高轉(zhuǎn)換率,能夠完美應(yīng)用于樓宇中的狹小空間。
高M(jìn)TBF數(shù)值保障完美的可靠性
電源的轉(zhuǎn)換效率高意味著由電源產(chǎn)生的能量損耗低,也就意味著系統(tǒng)運(yùn)行時(shí),在開關(guān)柜或間隙內(nèi)產(chǎn)生和匯聚的熱量少。這也使得電源以及電氣設(shè)備的工作環(huán)境溫度更低,由此可以延長(zhǎng)電源和系統(tǒng)的使用壽命,提高平均故障間隔時(shí)間 (MTBF) 值。在LED照明應(yīng)用中,電源的長(zhǎng)壽是必不可少的,高平均故障間隔時(shí)間(MTBF)值也意味著能降低故障率。魏德米勒PROtop系列電源,屬于電源的高端系列,可靠性高且抗干擾能力強(qiáng),輸出保護(hù)高,在個(gè)別設(shè)備發(fā)生故障時(shí),能提供可靠的持續(xù)供電,維持關(guān)鍵的系統(tǒng)運(yùn)行。魏德米勒PROtop系列電源耐高溫高濕,防護(hù)性更好,不容易“凝露”。同時(shí),在電源的輸出側(cè)安裝電子負(fù)載監(jiān)控maxGUARD電子熔絲,能增加保護(hù)等級(jí)且進(jìn)行快速的故障診斷。魏德米勒這種“組合拳”形式的解決方案,保障了煙草的加工更加流暢。魏德米勒PROtop電源的高可靠性、耐用性和緊湊性,都使其成為客戶的首選。得益于專利的DCL技術(shù)(DCL——輸出動(dòng)態(tài)過流),
after the coke loading, coke dry quenching and other steps. The hot coke is discharged from the coke discharge system at the lower part of the dry quenching furnace after being cooled by nitrogen circulation in the dry quenching furnace. Whether the cooled coke can be automatically, continuously and evenly discharged to the belt conveyor and transported to the corresponding transfer station is related to the cooperation efficiency of the whole CDQ system. Therefore, it is particularly important to realize the reasonable chain control of the coke discharge system, and the application of PLC system is very necessary. Taking the coking supporting CDQ project of Qian'an Jiujiang coal storage and Transportation Co., Ltd. as an example, the realization of automatic control in the coke discharge system is analyzed in detail.
1 hardware composition of automatic control system
The network topology of the whole CDQ automatic control system is divided into three layers: Fieldbus layer, that is, fieldbus dual network communication is adopted between PLC and field equipment such as frequency converter and encoder; The basic control layer, that is, redundant communication between the main
