长自动限温加热带的电学性能

On the Electrical Behavior of Long Self-Temperature-Limiting Heating Strip

将均匀传输线公式应用于自动限温加热带,可从短加热带的测试结果估算长加热带的主要电性能,如电流、功率及其沿带长的分布,上述讨论得到实验验证。该结果有助于加热带的设计、测试及应用。

The major electrical parameters of long self-temperature-limiting heatingstrip, such as current, power and their distribution along the strip, can becalculated from the test results of short strip sample by making use of the e-quations of uniform. propagation line. The discussion mentained above has beencomfirmed by experimental data. The imformation is helpful for the design,test and application of the heating strip.
