Research on Temperature Rise Experiment and Temperature Field Simulation of Electrical Penetrations in Nuclear Power Plants

This article combines the actual situation of electrical penetrations in a domestic nuclear power plant to complete temperature rise tests on 17 sets of conductor components of electrical penetrations, and conducts research and verification on the conductor heating law and temperature monitoring methods of electrical penetrations; Taking the penetration component as the research object, using Comsol finite element analysis software, a finite element model of three temperature fields of the penetration component is established. Heat sources are loaded at both ends of the conductor component to simulate the transient temperature field and temperature curves at the ends and inside of the penetration component. We need to provide data support for the maximum internal and external temperature during the thermal aging test of penetration components through experiments.
