2018-4-8 16:44:35點擊：
電纜穿線管及端子箱電纜孔洞的封堵,是變電站防火、防潮、防小動物的關鍵環節。因其封堵環境不方正,阻攔物較多,施工封堵質量很難控制。導致在設備運行中,出現小動物侵害,設備受潮等事件的發生。該發明從簡單實用,方便美觀和可重復利用等幾個方面綜合考慮,研制出一種新型的電纜穿線管及端子箱電纜孔洞封堵裝置,目的在于降低運維成本,降低封堵不可靠帶來的設備隱患。
封堵方式及特點分析
對(dui)于有(you)(you)機(ji)(ji)封(feng)堵(du)(du)來說，優(you)點(dian)：①材料為合成有(you)(you)機(ji)(ji)樹脂(zhi)，可以(yi)直接(jie)作(zuo)為粘接(jie)劑使用；②可塑(su)性(xing)較(jiao)強；③有(you)(you)較(jiao)長(chang)的(de)耐火時間，且質(zhi)地較(jiao)為柔軟；④可以(yi)重復(fu)利用且可修復(fu)。缺點(dian)：①比較(jiao)容易受到破(po)壞；②牢(lao)度較(jiao)差，污染也(ye)較(jiao)重；③易發生垮塌(ta)(ta)缺陷，在實踐(jian)(jian)中，在端(duan)子箱的(de)底部(bu)，孔(kong)洞(dong)較(jiao)大的(de)位置一(yi)(yi)般(ban)較(jiao)易發生垮塌(ta)(ta)問題。對(dui) 于無機(ji)(ji)封(feng)堵(du)(du)來說，優(you)點(dian)：①質(zhi)地較(jiao)為穩定(ding)，不(bu)容易被(bei)破(po)壞；②箱內的(de)污染較(jiao)少，封(feng)堵(du)(du)比較(jiao)美觀(guan)。缺點(dian)：①對(dui)于技(ji)術人(ren)員封(feng)堵(du)(du)技(ji)能(neng)有(you)(you)一(yi)(yi)定(ding)的(de)要求(qiu)；②對(dui)于堵(du)(du)料的(de)配比有(you)(you)較(jiao)嚴格的(de)要求(qiu)，不(bu)容易實踐(jian)(jian)操作(zuo)； ③雖然采用水泥加耐火磚的(de)方式實施封(feng)堵(du)(du)較(jiao)為堅實，也(ye)能(neng)較(jiao)好(hao)的(de)預(yu)防(fang)小動(dong)物進入，但對(dui)于技(ji)能(neng)有(you)(you)一(yi)(yi)定(ding)
的(de)要求(qiu)，比如對于出(chu)現(xian)的(de)返潮和水汽等問(wen)題；④較為容易產生污染。

對(dui)于有(you)(you)機(ji)(ji)封(feng)堵(du)(du)來說，優(you)點(dian)：①材料為合成有(you)(you)機(ji)(ji)樹脂(zhi)，可以(yi)直接(jie)作(zuo)為粘接(jie)劑使用；②可塑(su)性(xing)較(jiao)強；③有(you)(you)較(jiao)長(chang)的(de)耐火時間，且質(zhi)地較(jiao)為柔軟；④可以(yi)重復(fu)利用且可修復(fu)。缺點(dian)：①比較(jiao)容易受到破(po)壞；②牢(lao)度較(jiao)差，污染也(ye)較(jiao)重；③易發生垮塌(ta)(ta)缺陷，在實踐(jian)(jian)中，在端(duan)子箱的(de)底部(bu)，孔(kong)洞(dong)較(jiao)大的(de)位置一(yi)(yi)般(ban)較(jiao)易發生垮塌(ta)(ta)問題。對(dui) 于無機(ji)(ji)封(feng)堵(du)(du)來說，優(you)點(dian)：①質(zhi)地較(jiao)為穩定(ding)，不(bu)容易被(bei)破(po)壞；②箱內的(de)污染較(jiao)少，封(feng)堵(du)(du)比較(jiao)美觀(guan)。缺點(dian)：①對(dui)于技(ji)術人(ren)員封(feng)堵(du)(du)技(ji)能(neng)有(you)(you)一(yi)(yi)定(ding)的(de)要求(qiu)；②對(dui)于堵(du)(du)料的(de)配比有(you)(you)較(jiao)嚴格的(de)要求(qiu)，不(bu)容易實踐(jian)(jian)操作(zuo)； ③雖然采用水泥加耐火磚的(de)方式實施封(feng)堵(du)(du)較(jiao)為堅實，也(ye)能(neng)較(jiao)好(hao)的(de)預(yu)防(fang)小動(dong)物進入，但對(dui)于技(ji)能(neng)有(you)(you)一(yi)(yi)定(ding)
的(de)要求(qiu)，比如對于出(chu)現(xian)的(de)返潮和水汽等問(wen)題；④較為容易產生污染。
