MX 空气附加绝缘型母线槽
HBCE
Air-insulated insulated busway

概述 Overview
MX 空气附加绝缘型母线槽适用于交流三相四线制、三相五线制、频率 50-
60Hz，额定电压至 660V 的供配电系统，承担配电任务，用于低压配电屏与大、
中型负载的连接，主要用于现代化的车间、厂房和高层建筑。
MX air additional insulated busway is suitable for AC three-phase
four-wire system, three-phase five-wire system, frequency 50-60Hz,
rated voltage to 660V power supply and distribution system, for power
distribution tasks, for low-voltage power distribution panels and large
The connection of medium-sized loads is mainly used in modern
workshops, workshops and high-rise buildings.

主要技术参数 The main technical parameters

◆ 额定绝缘电压：660V；
◆ 额定频率：50~60Hz；
◆ 额定电流：见表 1；
◆ 绝缘电阻：每段母线槽的绝缘电阻应大于或等于 20MΩ, 用户安装时应检验绝缘电阻值后再进行安装；
◆ 介电强度：每一段母线槽单元出厂前均经受 50Hz/3750V/min 工频压试验；
◆ 短路强度：母线槽能承受表 2 规定的额定短时耐受电流和额定峰值附受电流所产生的热应力和电动力 , 经承受后无永久性可视察变形。
◆ Rated insulation voltage: 660V;
◆ Rated frequency: 50~60Hz;
◆ Rated current: see Table 1;
◆ Insulation resistance: The insulation resistance of each busbar slot should be greater than or equal to 20MΩ. The user should check the
insulation resistance value before installation.
◆ Dielectric strength: Each busbar slot unit is subjected to 50Hz/3750V/min power frequency voltage test before leaving the factory.
◆ Short-circuit strength: The busbar drawing can withstand the thermal stress and electric power generated by the rated short-time withstand
current and the rated peak-affected current specified in Table 2. After permanent bearing, there is no permanent visible deformation.
