射频同轴电缆发热时间常数的确定方法

Determination Method of Heating Time Constant for RF Coaxial Cable

射频同轴电缆发热时间常数是指电缆加热到稳态温升的63.23%所需要的时间,是射频同轴电缆额定功率测试过程中的关键参数。基于发热时间常数的重要性,介绍了确定发热时间常数的方法,并指出了其在电缆超功率运行等方面的应用。

Radio frequency（RF）coaxial cable heating time constant means the time that the cable needs to be heated up to 63.23% of the equilibrium temperature rise and it is the key factor in the rated power test process of RF coaxial cable.Based on the significance of the heating time constant,the determination method of the constant is given.And the application of the cable in overpower operation is also introduced.
