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
