前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T7357—2010《船舶電氣設(shè)備系統(tǒng)設(shè)計(jì)保護(hù)》，與GB/T7357—2010相比，

除結(jié)構(gòu)調(diào)整和編輯性改動(dòng)外，主要技術(shù)變化如下：

a）增加了“基礎(chǔ)保護(hù)”“電力負(fù)荷分析”的定義（見(jiàn)3.11、3.12）；

b）增加了電力系統(tǒng)分析、計(jì)算的規(guī)定（見(jiàn)4.3）；

c）增加了電力負(fù)荷分析的規(guī)定（見(jiàn)第5章）；

d）更改了短路電流的規(guī)定，增加了短路電流計(jì)算的規(guī)定（見(jiàn)第6章，2010年版的第5章）；

e）增加了選擇性保護(hù)分析的規(guī)定（見(jiàn)第7章）；

f）刪除了照明電路的保護(hù)和岸電連接的保護(hù)的相關(guān)規(guī)定（見(jiàn)2010年版的8.7、8.8）；

g）增加了欠頻率和過(guò)頻率保護(hù)的規(guī)定（見(jiàn)第14章）。

本文件等同采用IEC60092?202：2016《船舶電氣設(shè)備第202部分：系統(tǒng)設(shè)計(jì)保護(hù)》。

本文件做了下列最小限度的編輯性改動(dòng)：

—將標(biāo)準(zhǔn)名稱修改為《船舶電氣設(shè)備系統(tǒng)設(shè)計(jì)保護(hù)》。

請(qǐng)注意本文件的某些內(nèi)容可能涉及專利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識(shí)別專利的責(zé)任。
