摘要
通过计算推导,得到了GB1094.5《电力变压器第5部分承受短路能力》中介绍的变压器突发短路后热稳定平均温度计算公式。导出了各种绝缘系统和耐热等级下的导体的最大允许电流密度值。给出了计算实例。
The formula for calculating heat stabilization average temperature of transformer after sudden short-circuit test is obtained by calculation and derivation. It's introduced in GB1094.5, Power Transformer Part 5: Ability to Withstand Short Circuit. The maximum allowable current density of conductor is developed under different kinds of insulation system and temperature classification. The calculation example is given.
