摘要
针对母线槽在短路耐受强度型式试验过程中遇到的一些故障,结合IEC 60865-1、IEC/TS 60865-2和GB 7251.2—2006标准,以及试验过程中采集到的示波图,分析了产生类似故障的原因。探讨了母线槽承受短时间、大电流所形成的电动力和热效应的能力,并对母线槽导体截面积的选择排列和绝缘支撑件的布局、安装方式提出建议。
Aiming at some faults encountered in the process of busway short circuit withstand strength test, combining with the international standards IEC 60865-1 and IEC/TS 60865-2, national standard GB 7251.2—2006, and oscillograms collected in the experiment, this paper analyzed the causes leading to analogous faults. Discussion was made to the capability of busway forming electrodynamic force and heat effect under a short period of time and large current. This paper puts forward some reasonable suggestions to the selection and arrangement of busway conductor cross-section, layout of insulation support and installation methods.
