Numeral Analysis by Using Balance Method of Volume Control inside the Temperature Field of the Low-Voltage Circuit

摘要：

This paper studies the temperature field in the interrupter room of the low-voltage circuit breaker by using the modal of DZ15LE-100/4901-type leakage circuit breaker. It is based on the study of the magnetic flow field analysis and numerical heat transfer study - diffusion equations. Taking the processes of contact and break of the interrupter as a whole, the heat value of two processes is different. This paper is on the study of heat transfer numerical analysis, and makes a conclusion of algebraic equations of the interrupter temperature field by using the method of volume balance for numerical heat transfer study. This method is used for the research of regional dispersion, discrete equation of the hot-node coupling and transferring differential equations into algebraic equations.
