摘要

气体绝缘开关柜（C-GIS）的导电回路封闭在充有绝缘气体的隔室内。由于隔室内部气体不能有效地与外界空气进行热交换

因此内部热量难于散出

特别是大电流的气体绝缘开关柜尤为突出。因此大电流气体绝缘开关柜的发热成为设备制造企业和用户共同关注的问题。文中采用多物理场耦合方法对充入干燥空气的气体绝缘开关柜进行了温度仿真

分析了内部温度分布特性

并将温升试验结果与仿真结果进行了对比

验证了该仿真方法的准确性

为气体绝缘开关柜散热优化设计提供了依据。

Abstract

The conductor circuit of gas insulated switchgear is sealed in the gas chamber.The inner heat can not be effectively exchanged with outer air so the heat couldn’t dissipate.Especially when the current is very large.Therefore the temperature-rise of gas insulated switchgear is becoming a focus for manufactures and users.In this paper we simulated a 3-D model of dry air insulated switchgear by coupling field approach and analyzed the properties of inner heat distribution identified the accuracy of simulation by comparing the data of temperature-rise between experiment and simulation and provided the evidences of optimized design for gas insulated switchgear heat dissipation.
