FSEL003半導體模塊,SCHENCK英文說(shuō)明
工業(yè)直流備用電源可為指定的驅動(dòng)器而不是整個(gè)交流網(wǎng)絡(luò )提供靈活的輸出功率控制。通過(guò)直接向關(guān)鍵負載設備的逆變器而不是整個(gè)系統供電,可以為用戶(hù)節省能耗。進(jìn)而降低了系統的投入成本。其次,工業(yè)直流備用可以與不同的儲能技術(shù)兼容。您可以使用一種存儲技術(shù),也可以使用多種存儲技術(shù)的組合,例如鋰離子電池,超級電容器,液流電池和超級電容器。通過(guò)丹佛斯的工業(yè)直流備用電源,用戶(hù)可以升級現有安裝,通過(guò)并行安裝擴展電源大小,以滿(mǎn)足隨著(zhù)時(shí)間的推移不斷增長(cháng)的需求。相比使用不間斷電源,用戶(hù)可以最大限度的節約成本。
FSEL003半導體模塊,SCHENCK英文說(shuō)明儲能技術(shù)是新能源產(chǎn)業(yè)革命的重要發(fā)展趨勢,我國儲能產(chǎn)業(yè)正在快速成長(cháng)為在全球有重要影響的新興戰略性產(chǎn)業(yè),這也將極大促進(jìn)國內新能源的規?;l(fā)展。丹佛斯將始終致力于為用戶(hù)提供最優(yōu)化的產(chǎn)品和解決方案。工業(yè)現場(chǎng)供電,我們必須會(huì )使用到電源,電源的供電質(zhì)量和產(chǎn)品性能是確?,F場(chǎng)設備穩定運行的關(guān)鍵因素。從現場(chǎng)運行穩定性和更換成本的角度考慮,客戶(hù)肯定會(huì )優(yōu)先使用故障率低,壽命高的電源,但是從采購成本考慮,只要上述兩個(gè)參數能夠達到現場(chǎng)可用性的標準,那么選擇一些折中的電源方案也很常見(jiàn)。但是本文考慮的是另一種情況,即對于現場(chǎng)斷電率控制要求極其嚴格的一些應用。石化、核電、軌交等行業(yè),一方面對于現場(chǎng)運行安全性的要求極高,另一方面一旦出現停機,就會(huì )產(chǎn)生很高的效益損失和維護成本。因此在降低電源自身故障率的基礎上還需要加一層保障確保系統最高的可用性,這就要提到“冗余供電”這個(gè)概念,其實(shí)現方式并不復雜,即使用多臺電源輸出直接并聯(lián)的方式(通常一些行業(yè)使用兩臺電源),當一臺電源損壞,負載仍然能通過(guò)另外的電源來(lái)繼續得到供電。雖然采購成本成倍增加,但是綜合現場(chǎng)運行風(fēng)險的把控和維護,這些投入也是值得的。
接觸器相關(guān)的能效標準(GB21518-2008《交流接觸器能效限定值與能效等級》)對于一級能效的要求非常高,除了永磁式接觸器,其他傳統交流接觸器無(wú)法達到此標準,對傳統交流接觸器的引導作用有限。與2008版的標準相比,如今正在擬制的標準對傳統交流接觸器的能效提高更有引導作用,把一級能效的要求放寬,對二級能效、三級能效的要求變嚴。
In addition, the pre crusher room is also equipped with a mechanical dust removal device to make the indoor dust content meet the safety and health requirements. The task of the coal blending room is to mix various brands of coking coal according to the proportion determined by the coal blending test, so that the blended coal can be refined into coke that meets the quality requirements, and achieve the purpose of rational utilization of coal resources and reducing production costs.
The coal blending room is composed of 14 f10m hyperbolic nozzle coal blending tanks, which are arranged in double rows. Each single kind of coal is divided into two groups for storage according to coal quality. Reversible bin distribution belt conveyor is used for distribution at the top of the trough. The storage capacity of each coal blending tank is about 800t, and the total storage capacity is 11200t, which can provide about 26.6 hours of coal consumption for four coke ovens.
The coal blending tank adopts the hyperbolic nozzle with equal section shrinkage, which has good adaptability to the water content in the coal, can prevent the coal from being shed in the coal blending tank, and improve the accuracy of coal blending.
