基于外壳尺寸和元器件功耗计算低压成套开关设备温升的算法
An Algorithm for Calculating Temperature Rise of Low-voltage Switchgear Assemblies Based on Shell Sizes and Component Power Consumption
摘要
Abstract
According to GB/T 24276-2017,the paper puts forward an algorithm for calculating temperature rise of low-voltage switchgear assemblies based on shell sizes and component power consumption.The principle of this algorithm is to determine the internal air temperature rise of the shell,according to the sizes and the heat dissipation area of the shell,to obtain the temperature rise of the air inside the shell.The data obtained by calculation was used to calculate the predicted temperature rise and draw the temperature rise curve,fitting well with the actual temperature rise curve,which verified the feasibility of the algorithm for temperature rise prediction.The algorithm is expected to help enterprise design and test station inspectors,and improve the quality level and the inspection efficiency of high-voltage&low-voltage electrical appliance industry.关键词
