中文摘要: |
PTC元件是一种特殊的正温度系数的热敏电阻元件,其阻值一温度特性具有"延时断开"特性.可以在一些电气控制线路中取代时间继电器,从而简化线路,提高可靠性.给出了PTC元件的应用实例,探讨了应用时的一些问题. |
英文摘要: |
The PTC component being presented in this article is a special kind of positivetemperature coefficient resistance component, which feature of value of resistance -temperature can be characterized by "delayed action of switching off". If the PTCcomponents substitute the timer to be used in some electric bang-bang control circuits, thecircuits can be simplified and their reliability can be raised. This article presents twoexamples of the PTC component and discusses some practical problems. |
