摘要：本文研究测温传感器安装在开关柜仪表室或柜顶泄放通道，通过对这些位置温度的监测，根据高压开关柜的热物理模型，计算出断路器触头等发热部位的温度，从而达到对开关柜易发热部位间接测温的目的。本文的研究结果，亦可为其他同类的电流致热型电气设备的传热特性、温升分布规律、测温诊断等研究作为理论参考。

STUDY ON INDIRECT TEMPERATURE MEASURING METHOD OF HIGH VOLTAGE SWITCH CABINET
Abstract:This paper studies the temperature sensor installed in the switch cabinet on channel instrument room or cabinet top discharge, by monitoring the temperature of these positions, according to the thermal physical model of high voltage switch cabinet, calculate the circuit breaker contact parts of the heating temperature, so as to achieve the switch cabinet temperature to indirect heating position. The results of this paper can also be used as a theoretical reference for the study of heat transfer characteristics, temperature rise distribution and temperature diagnosis of other similar current heat type electric equipment.
Keywords：Switch cabinet, Indirect temperature measurement, Temperature distribution, Thermal physical model, Temperature diagnosi
