是不是只要隨便安裝一個(gè)漏電保護(hù)器都能保護(hù)人身和設(shè)備的安全呢？答案是否定的。要使漏電保護(hù)器能安全有效地保障我們?nèi)松戆踩?，必須要從下面幾個(gè)主要參數(shù)來選擇和考慮。

●業(yè)從事（DCS系統(tǒng)）（機(jī)器人系統(tǒng)）（大型伺服控制系統(tǒng)）模塊 備件銷售廈門[泰尼電氣有

　　轉(zhuǎn)子流量計(jì)在工業(yè)生產(chǎn)過程中應(yīng)用較廣，可以測(cè)量多種介質(zhì)的流量，特別適用于中小管徑和低雷諾數(shù)的中小流量測(cè)量。轉(zhuǎn)子流量計(jì)結(jié)構(gòu)簡(jiǎn)單，靈敏度高，量程比寬（10：1），壓力損失小且恒定，對(duì)直管段的要求不高，刻度近似線性，價(jià)格便宜，使用維護(hù)簡(jiǎn)便。但儀表受被測(cè)介質(zhì)密度、粘度、溫度、壓力等因素的影響，其精度一般在1．5級(jí)左右。

1、額定電流In

是指能夠持續(xù)流過漏電保護(hù)器的最大負(fù)載電流。這需要根據(jù)家中各種電氣設(shè)備的功率之和P來計(jì)算確定，即：I=P/220。算出負(fù)載電流I后，再選擇額定電流In比計(jì)算電流略大一點(diǎn)的漏電保護(hù)器，這樣，在正常使用中，不至于漏電保護(hù)器因過負(fù)荷經(jīng)常動(dòng)作，影響正常使用。按目前的生活水平和電器普及的程度，我單位院區(qū)電路改造時(shí)，為各戶選用In為20A的漏電保護(hù)器是小了一點(diǎn)，因此本人建議將In改為32A或40A，得到了領(lǐng)導(dǎo)的采納。

目前，市場(chǎng)上常見的家用漏電保護(hù)器額定電流In規(guī)格有：16A、20A、25A、32A、40A、63A。
