H级6kV高压防爆电机绝缘结构的探讨

针对H级高压三相异步电动机的绝缘结构进行了探讨，认为6kV及以上电压等级的定子线圈主绝缘，采用有机硅玻璃布补强粉云母带或环氧二苯醚玻璃布补强粉云母带时，严重影响定子线圈的常态和热态介损，会缩短线圈绝缘的电热老化寿命，故应采用新型H级云母带或其他H级云母带。

Approach to Insulation Structure of Grade H 6kV High Voltage Ex Motor

This article approaches the insulation structure of Grade H high voltage three phase induction motor,And draws a conclusion:it has a strong impact on the dielectric losses both in normality and thermal state for stator coil to adopt organosilicon glass cloth reinforcement mica paper tape or epoxy diphenyl oxide glass cloth reinforcement mice paper tape in the major insulation of 6kV and/or upwards high voltage stator coils,thus it may shorten the electroheat Aging longevity of coil insulation.For this reason,it should be adopted a newly Grade H mice tape or others
