讲述了光纤温度传感器用于在线测量高压电气设备内部绝缘温度的原理和方法,并说明这种测量方法在实际应用中的意义。
The principle and method of measuring the internal temperature of insulator of online HV equipment by optical temperature sensor is described, and the advantages of the method in practice are given.
在右侧的黑色绝缘胶带下,是一个感应金属杆的外界温度的传感器。
On the right, under black electrical tape, is a sensor for ambient temperature taken from the metal pole.
这个主要取决于内外空气的温度差、绝缘层的类型和厚度以及传导面的面积。
It is dependent on the temperature differential between the inside and outside air, type and thickness of insulation, and the area of the conducting surfaces.
Now, you can have a change of temperature without any heat being involved.
不进行热量传递也可以改变温度,想象有一个热绝缘的盒子。
