描述

國內(nèi)大多數(shù)繼電器負(fù)載能力，只標(biāo)最大純阻性負(fù)載，這給用戶在選擇繼電器負(fù)載時(shí)，產(chǎn)生二種誤解，導(dǎo)致選型失誤。誤解之一是：用戶實(shí)用的往往不是純阻負(fù)載，而是感性的、燈的、電機(jī)的或容性的負(fù)載，負(fù)載大小等同或接近于阻性負(fù)載；誤解之二是：負(fù)載可以從低電平到額定負(fù)載，均能適應(yīng)。應(yīng)該指出，能可靠轉(zhuǎn)換10A阻性負(fù)載的繼電器，不可轉(zhuǎn)換10A的感性負(fù)載，不一定能可靠轉(zhuǎn)換10mA的負(fù)載。因?yàn)椴煌再|(zhì)負(fù)載條件下的電接觸失效機(jī)理是截然不同的。應(yīng)該強(qiáng)調(diào)，觸點(diǎn)故障是繼電器失效的主要原因。正確理解觸點(diǎn)在不同負(fù)載類型、不同負(fù)載大小條件的電接觸特性、失效現(xiàn)象及失效機(jī)理，統(tǒng)一制造方與用戶的認(rèn)識(shí)，對(duì)提高繼電器工作的可靠性，尤為重要。制造廠應(yīng)改進(jìn)觸點(diǎn)負(fù)載的標(biāo)識(shí)、內(nèi)容，對(duì)不同負(fù)載類型應(yīng)分別標(biāo)注
