基于10kV开关柜热场分析的温度监测点选取方法研究
Research on Temperature Monitoring Point Selection Method Based on Thermal Field Analysis of 10 kV Switchgear Cabinet
摘要
Abstract
Temperature sensors can not be installed directly on some critical parts as circuit breaker contact of switchgear cabinet.For obtaining suitable temperature sensing monitoring points to achieve the monitoring and pro-tection of the switchgear cabinet,in this paper type KYN28A-12 type 10 kV switchgear cabinet is taken as the re-search object,the three-dimensional physical model of the switchgear cabinet is set up and the temperature field dis-tribution of the switchgear cabinet under rated condition is obtained through Ansys simulation so to intially provide theoretical basis for subsequent selection of monitoring point.To addrss the complex operating conditions of the switchgear cabinet,the temperature field simulations under such various conditions as ambient temperature and cur-rent-carrying capacity are performed by the authors in this paper.Based on the simulation result and theoretical analy-sis,some busbar nodes with significant temperature variations are finally selected as the temperature monitoring points,and the influence differentce of temperature rise of those monitoring points under different operating condi-tions are specifically analyzed and the rationality of the temperature monitoring points selected in the paper is verified.关键词
