当我们在郊外散步或乘车旅行时,总可以看到在田野上、在崇山峻岭、在大江南北都有许多高压输电线路伸向祖国的每个角落,它们每时每刻都给各行各业送来巨大的动力。那末,怎样才能保证输电线路的正常运行呢?过去,需要许多维修人员长年累月奔走于线路上,经常爬上爬下、一个一个地检查各电缆接头、各电气元件是否工作正常。而现在,人们把一种称之为红外测温仪或红外热象仪的仪器装在车辆或直升飞机上沿着线路行驶(或飞行),将仪器瞄准电缆接头或电气元件,在很短时间内就可以精确的测出接头(或电气元件)的温度是多少,是否正常工作,…这样做既省事又省人,又快又安全,这种测量技术就是红外无损检测。
As we walk or travel by car in the suburbs, we can always see that there are many high-voltage transmission lines in every corner of the motherland in the fields, in the mountains and mountains, and all over the country. Huge motivation. How can we ensure the normal operation of the transmission line? In the past, many maintenance personnel needed to run the line for many years and often climbed up and down and checked the cable connectors one by one and whether the electrical components were working properly. Now, people put a device called an infrared thermometer or an infrared camera on a vehicle or a helicopter to run (or fly) along a line, aim the instrument at a cable or electrical component, Time can accurately measure the connector (or electrical components) temperature is how much, is working properly, it is both easy and save people, fast and safe, this measurement is infrared non-destructive testing.
