摘要

额定通流温升作为评估真空断路器工作状态的一项重要参数，目前主要依赖于电磁耦合仿真。然而，这种方法针对不同结构、尺寸的触头模型需要耗费大量时间建模。文中提出了一种基于热路方法的真空灭弧室额定通流温升估算模型，与传统的电磁耦合仿真模型相比，热路模型能快速反映高压真空断路器的温升，有助于高压真空断路器的通流结构设计。针对真空灭弧室的通流结构，构建了由热流和热阻构成的热路模型。建立了2/3匝线圈触头的热路模型，并基于触头结构的物理参数，将热路中的元件参数化，仿真获得了真空灭弧室触头的关键节点的温升值。通过与真空灭弧室的电磁耦合仿真结果对比，验证了热路模型的准确性和效率。

Abstract

Temperature rise of rated current

as an important parameter for assessing the status of vacuum circuit breaker

currently relies primarily on electromagnetic coupling simulation. However

this method requires considerable time for modeling contact models with different structures and dimensions. In this paper a temperature rise estimation model for the rated current of vacuum interrupter based on a thermal circuit method is proposed. The thermal circuit model

compared with the traditional electromagnetic coupling simulation model

can quickly reflect the temperature rise of high-voltage vacuum circuit breaker

which is conducive to the design of current-carrying structures for high-voltage vacuum circuit breaker. A thermal circuit model consisting of heat flow and thermal resistance is constructed for the current-carrying structure of the vacuum interrupter. The thermal circuit models for 2/3 turn coil contacts are set up

and the components in the thermal circuit are parameterized based on the physical parameters of the contact structure. The temperature rise values of the key nodes of the vacuum interrupter contact are obtained by simulation. Both accuracy and efficiency of the thermal circuit model are verified by comparison with the electromagnetic coupling simulation results of the vacuum interrupter.
