摘要 温升是衡量开关设备能否长期稳定运行的重要因素之一。本文以典型结构KYN96-12的出线柜为例,探讨了进行高压开关柜热效应仿真分析的方法。首先将柜体有效简化,生成了合理的有限元模型;然后利用电磁仿真分析软件,对开关柜的发热功率进行了仿真分析;最后通过稳态热分析得到了开关柜导体的温度场数据。试验数据验证了简化的开关柜模型是合理的,热仿真分析的方法是正确的。开关柜的仿真数据对其温升优化设计具有指导意义。

Abstract:To measure if the switchgear can run steady long-term, temperature rise is an important factor. Based on the example ofoutlet cabinetwith typical structure KYN96-12, method of thermal simulation about high-voltage switchgear was discussed. First, the switchgear was simplified effectively and reasonable finite element model was generated. Then heating power of the switchgear was simulated through an electromagnetic simulation software. At last, temperature field data was obtained after the steady state thermal analysis. Test results have verified that simplified switchgear model is reasonable and method of heating effect simulation proper. Simulation data of switchgear can guide the optimization design of its temperature rise.
