塑殼斷路器工作條件
 周圍空氣溫度

 周圍空氣溫度上限+40℃;○ 周圍空氣溫度下限-5℃;○ 周圍空

氣溫度24h的平均值不超過+35℃。

海拔:安裝地點(diǎn)的海拔不超過2000m。

大氣條件：
大氣相對濕度在周圍空氣溫度為+40℃時(shí)不超過50%;在較底溫度

下可以有較高的相對濕度;zui濕月的月平均zui大相對濕度為90%,

同時(shí)該月的月平均zui低溫度+25℃,并考慮到因溫度變化發(fā)生在產(chǎn)

品表面上的凝露。

污染等級:污染等級為3極。

情況概述
塑殼斷路器也被稱為裝置式斷路器，所有的零件都密封于塑料外

殼中，輔助觸點(diǎn)，欠電壓脫扣器以及分勵脫扣器等多采用模塊化

。由于結(jié)構(gòu)非常緊湊，塑殼斷路器基本無法檢修。其多采用手動

操作，大容量可選擇電動分合。由于電子式過電流脫扣器的應(yīng)用

，塑殼斷路器也可分為A類和B類兩種，B類具有良好的三段保護(hù)

特性，但由于價(jià)格因素，采用熱磁式脫扣器的A類產(chǎn)品的市場占

有率更高。 塑殼斷路器是將觸頭、滅弧室、脫扣器和操作機(jī)構(gòu)等

都裝在一個(gè)塑料外殼內(nèi)，一般不考慮維修，適用于作支路的保護(hù)

開關(guān)，過電流脫扣器有熱磁式和電子式兩種，一般熱磁式塑殼斷

路器為非選擇性斷路器，僅有過載長延時(shí)及短路瞬時(shí)兩種保護(hù)方

式，電子式塑殼斷路器有過載長延時(shí)、短路短延時(shí)、短路瞬時(shí)和

接地故障四種保護(hù)功能。部分電子式塑殼斷路器新推出的產(chǎn)品還

帶有區(qū)域選擇性連鎖功能。大多數(shù)塑殼斷路器為手動操作，也有

部分帶電動機(jī)操作機(jī)構(gòu)。

其具體試驗(yàn)是：把線路的電流調(diào)整到預(yù)期的短路電流值（例如

380V ，50kA），而試驗(yàn)按鈕未合，被試斷路器處于合閘位置

，按下試驗(yàn)按鈕，斷路器通過50kA短路電流，斷路器立即開斷

（open簡稱O），斷路器應(yīng)完好，且能再合閘。t為間歇時(shí)間，

一般為3min，此時(shí)線路仍處于熱備狀態(tài)，斷路器再進(jìn)行一次接
