耐火母线的一些知识点Some knowledge points of fire-resistant busbar
耐火母线厂家认为在许多大型建筑或重要建筑中,除了正常的供配电外,还配备柴油发电机作为应急电源。一旦电网供电线路出现问题或建筑物发生火灾导致市电跳闸断电,需要柴油发电机组发电临时供电,以保证重要工作不会停止,或保证疏散照明指示人员疏散方向。柴油发电机发出的电需要经过变电站内的一些低压配电柜,馈给需要应急电源的用电设备。柴油发电机和变电站低压配电柜需要耐火封闭母线连接成一个综合供电系统。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.
耐火母线厂家认为随着现代工程设施和设备的出现,各行各业的用电量迅速增加,特别是许多高层建筑和大型车间的出现。在大电流传输系统中,传统的电缆作为传输线已经不能满足要求,多路电缆的并行使用给现场安装和施工连接带来了诸多不便。
耐火母线厂家认为母线安装在电力系统各级的电压分配装置中,其主要功能是收集、分配和输送电能。由于母线在运行中传输巨大的电功率,当通过大负载电流短路时,承受巨大的发热和电动力学效应。
耐火母线槽正在逐步替代电缆,种类也越来越多。今天就为大家介绍一下它的特点,让我们在购买时能够买到合适的? 1、耐火母线主要用于为消防设备供电,一般不作其他用途。有良好的耐热性和隔热性,但不能长期满负荷使用,主要是其散热效果不是很好。除耐火母线外,其他可长期满负荷运行。
