Abstract
Taking advantages of theoretical analysis,simulation calculation and test,the thermal characteristics of tank body of a tank-type circuit breaker are studied on the basis of simplified tank body model.Calculations show that the thermal power of conductor resistance is the main thermal source of the circuit breaker,and the eddy current loss can be basically ignored.On the other hand,the heat dissipation of the hot gas through convection is the main heat dissipation way of the circuit breaker.The thermal radiation effect of smooth surface conductor is weak,but that of the painted surface conductor cannot be ignored.The results of simulation calculation are basically consistent with those of temperature rise test,which proves the correctness of the methods adopted in the theoretical analysis and simulation calculation.关键词
