1746-C16固態(tài)繼電器的合理使用要注意過電流保護(hù)、過電壓的保護(hù)與過熱保護(hù)
固態(tài)繼電器過電流保護(hù)
固態(tài)繼電器是以半導(dǎo)體開關(guān)器件作為功率輸出部件的,對(duì)溫度的變化較為敏感,過電流會(huì)使半導(dǎo)體芯片過熱而造成品質(zhì)下降,壽命降低甚至永久性損壞。雖然固態(tài)繼電器在瞬間可以承受額定電流10倍以上的浪涌電流,但超過此值很容易造成永久性損壞。因而,過電流的保護(hù)是很重要的,過電流的保護(hù)關(guān)鍵在于反映速度要快,對(duì)以可控硅為輸出器件的交流固態(tài)繼電器,由于可控硅需電流過零關(guān)斷的特性則對(duì)于在10mS(50Hz)以內(nèi)超過SSR浪涌電流承受值的浪涌電流和短路電流
