摘　　要：引入热网络技术,建立了某型号瓷柱式高压断路器主回路的仿真模型。温升试验表明,实验结果与仿真结果之差的最大值误差为7.9%,该仿真方法的准确度在工程许可范围之内。基于此仿真模型,利用3种改善措施,观察其对断路器温升的影响程度。研究结果表明,应用热网络方法可以方便快捷地修改任意参数,了解其对电力设备热特性的影响,为产品设计提供参考。Based on the thermal network technology, a high voltage circuit breaker simulation model was established in this paper. The difference value between experimental and simulation results was 7.9%, and the thermal network method is effective for the power equipment thermal analysis. To observe the influence degree of circuit breaker temperature rise, three methods were adopted. This study shows that it is easily to modify parameter in the method, which provides the characteristic reference for products design.
