自复保险丝用户指南(RESETTABLE FUSE USER GUIDE)
2022-02-16
●自复保险丝的特点:
●The characteristics of PPTC resettable fuses:
■过电流保护:当设备电路出现过电流或短路故障时,自复保险丝会快速的从低电阻转变高阻状态,达到保护设备电路的目的。
■自动复位:当引起过载电流的故障排除后,自复保险丝自动复位,无需人工拆换。
■自锁(非循环)运作:自复保险丝触发后,以极小的电流锁定其高阻状态。在电源关闭和故障排除后,才会自动复位,从而避免了故障设备通断恶循环现象。
■耐大电流:自复保险丝具有极强的耐大电流能力,有些型号的产品可承受 100A 的冲击电流。
■抗雷击:自复保险丝具有抗雷击的功能。它可以使用在那种能把电流限定在相当低的程度又不会因瞬时雷电冲击而使系统失去操作性能的装置之中。
■快速断开:自复保险丝功能高分子材料的本征特性,使他限制电流的速度比其他类似的装置快得多。
■Protect the Devices against overcurrent and over-temperature the resistance of resettable fuses will change to very high state to cut off the current flow over the circuit as an overcurrent flow through the circuit, so as to protect the Devices against the failures.
■Resettable after power off and the failure has been eliminated, resettable fuses will recover to the initial state without any manual operation.
■Non-cycle running There are a little current flow over the fuse to keep high resistance of the fuse at tripping state until the failure is eliminated and the Devices is powered off.
■Large interrupting capacity Resettable fuses can cut off larger interrupting current, even more than 100A.
■Tolerance to lightning strike the resettable fuses can be used in the systems where may be some strong lightning surge flow over without any damage.
■Rapidly tripping PPTC resettable fuses trip more rapidly than other similar Devices.
