Abstract

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.
