耐火母線的一些知識點Some knowledge points of fire-resistant busbar
耐火母線廠家認為在許多大型建筑或重要建筑中,除了正常的供配電外,還配備柴油發(fā)電機作為應急電源。一旦電網(wǎng)供電線路出現(xiàn)問題或建筑物發(fā)生火災導致市電跳閘斷電,需要柴油發(fā)電機組發(fā)電臨時供電,以保證重要工作不會停止,或保證疏散照明指示人員疏散方向。柴油發(fā)電機發(fā)出的電需要經(jīng)過變電站內(nèi)的一些低壓配電柜,饋給需要應急電源的用電設(shè)備。柴油發(fā)電機和變電站低壓配電柜需要耐火封閉母線連接成一個綜合供電系統(tǒng)。Fire resistant busbar manufacturers believe that in many large or important buildings, in addition to normal power supply and distribution, diesel generators are also equipped as emergency power sources. Once there is a problem with the power supply lines of the power grid or a fire occurs in a building, causing the mains power to trip and cut off, a diesel generator set is needed to generate temporary power to ensure that important work does not stop or to ensure that evacuation lighting indicates the direction of personnel evacuation. The electricity generated by the diesel generator needs to pass through some low-voltage distribution cabinets in the substation and be fed to electrical equipment that requires emergency power supply. Diesel generators and low-voltage distribution cabinets in substations need to be connected with fire-resistant enclosed busbars to form a comprehensive power supply system.
耐火母線廠家認為隨著現(xiàn)代工程設(shè)施和設(shè)備的出現(xiàn),各行各業(yè)的用電量迅速增加,特別是許多高層建筑和大型車間的出現(xiàn)。在大電流傳輸系統(tǒng)中,傳統(tǒng)的電纜作為傳輸線已經(jīng)不能滿足要求,多路電纜的并行使用給現(xiàn)場安裝和施工連接帶來了諸多不便。
耐火母線廠家認為母線安裝在電力系統(tǒng)各級的電壓分配裝置中,其主要功能是收集、分配和輸送電能。由于母線在運行中傳輸巨大的電功率,當通過大負載電流短路時,承受巨大的發(fā)熱和電動力學效應。
耐火母線槽正在逐步替代電纜,種類也越來越多。今天就為大家介紹一下它的特點,讓我們在購買時能夠買到合適的? 1、耐火母線主要用于為消防設(shè)備供電,一般不作其他用途。有良好的耐熱性和隔熱性,但不能長期滿負荷使用,主要是其散熱效果不是很好。除耐火母線外,其他可長期滿負荷運行。
