摘 要：針對(duì)母線槽在短路耐受強(qiáng)度型式試驗(yàn)過程中遇到的一些故障，結(jié)合IEC60865-1、IEC/TS60865-2和GB7251.2—2006標(biāo)準(zhǔn)，以及試驗(yàn)過程中采集到的示波圖，分析了產(chǎn)生類似故障的原因。探討了母線槽承受短時(shí)間、大電流所形成的電動(dòng)力和熱效應(yīng)的能力，并對(duì)母線槽導(dǎo)體截面積的選擇排列和絕緣支撐件的布局、安裝方式提出建議。
關(guān)鍵詞：母線槽；短路耐受強(qiáng)度試驗(yàn)；導(dǎo)體截面積；動(dòng)熱穩(wěn)定

Abstract: 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.
Key words: busway; short-circuit withstand strength test; conductor cross-section; dynamic thermal stability
