This paper introduces the property requirements on insulating varnish and some techniˉcal indicators of import varnishes used in electronic transformer,discusses the effects of baking temperature,baking time,dry capability,impregnation process of varnish on the noise,rustiness,box craze,insulating tape bond failure which occurred in electronic transformer.
Teaching is a crucial step in the process of insulating generator stator′s bars with insulating tape. Two teaching algorithms based on online-dynamic and offline-PTP respectively are given. The numerical control insulating machine can obtain the central line track of the bar online or offline by them. The central line track obtained by the algorithms provides important geometrical data for the machine to insulate the bar with high quality.
In this paper,the related standard test methods for polyvinyl chloride adhesive insulating tape are reviewed.Standard test methods for adhesion,corrosion,flammability,temperature resistance and standard conditions of UL-510,ASTM D1000,IEC60454-2,PSTC standards,CSA C22.2No.197and Chinese standards(GB)are compared in detail.Various standard specifications for PVC insulating tape are introduced.HG/T3596which is the Chinese standard specification of polyvinyl chloride adhesive insu-latin...
