【国外标准】 IEEE Approved Draft Guide for Bus Design in Air Insulated Substations

This design guide provides direction for the substation engineer in the design of air insulated substations. This guide provides users with information on typical bus arrangements including various criteria necessary to develop bus arrangement decisions. The guide is applicable to both rigid bus and strain bus designs for outdoor and indoor, air-insulated, alternating current substations. This guide includes a method to calculate ampacity for electrical bus and ampacity tables for typical bus… read more types and sizes. This guide also provides design criteria and a method to calculate electromechanical forces on insulators and bus resulting from gravity, wind, ice, short circuit forces, and thermal expansion. This guide does not consider the following: a) The electrical criteria for the selection of insulators (see IEEE Std 1313.2TM[B22]) b) The seismic forces to which the substation may be subjected (see IEEE Std 693TM and IEEE Std 1527TM) c) The design of bus mounting structures (see ASCE Manual and Report on Engineering Practice No. 113) d) Design considerations for contaminated environments (see IEEE Std 1313.2-1999 [B22]) e) Installation methods f) Design of direct current buses read less
