電力是社會(huì)生產(chǎn)發(fā)展的時(shí)代產(chǎn)物,注意用電安全,應(yīng)該是我們生存的基本條件,用電設(shè)備注意安全,對(duì)于用電費(fèi)用煩惱的工廠主,可以考慮對(duì)用電設(shè)備進(jìn)行節(jié)電,節(jié)能節(jié)電節(jié)能環(huán)保。
配電室用電防范:在配電室內(nèi)設(shè)值班室或檢修室時(shí),該室距配電屏(盤(pán))的水平距離應(yīng)大于1米,并采取屏障隔離。配電屏單列布置宜靠墻安裝,正面的操作通道寬度不小于1.5米。配電屏單列布置宜靠墻安裝,正面的操作通道寬度不小于1.5米。配電室建筑五的耐火登記不低于3級(jí),室內(nèi)應(yīng)配置砂箱和適于撲救電器火災(zāi)的滅火器。
配電室應(yīng)能自然通風(fēng),并保持干燥,并采取防止雨雪和小動(dòng)物進(jìn)入的措施。配電室的門(mén)向外開(kāi),并配鎖。配電室的裸母線與地面的垂直距離小于2.5米時(shí),采取遮攔隔離,措施遮攔下方通行高度不小于1.9米;遮攔與帶電部分的凈距離不小于0.075米。配電室的頂棚距地面不小于3米。配電屏應(yīng)與重復(fù)接地線及保護(hù)零線做接地連接。配電屏單列布置宜靠墻安裝,正面的操作通道寬度不小于1.5米。
施工用電線路:架空線路,施工現(xiàn)場(chǎng)搬運(yùn)電桿時(shí),應(yīng)由專(zhuān)人指揮。電桿就位移動(dòng)時(shí),坑內(nèi)不許有人。人工立電桿時(shí),應(yīng)由專(zhuān)人指揮。架空線路距地面不小于4米,過(guò)路線的最低一層不低于6米。在建工程(含腳手架)的外側(cè)邊緣與外電架空線路的邊線之間的最小距離:1kv以下時(shí)為4米,1kv以上時(shí)為6米。
架空線路的干線設(shè)置(380/220V)應(yīng)采用鐵橫擔(dān),瓷瓶水平架設(shè),檔距不大于35米,線間距不小于0.3米。桿上緊線應(yīng)側(cè)向操作,并將夾緊螺栓擰緊,僅有角度的導(dǎo)線時(shí),操作人員應(yīng)在外側(cè)作業(yè)。大雨、大雪及六級(jí)以上的大風(fēng)天,停止登桿作業(yè)。電纜、電線:電纜的上下各均勻鋪設(shè)不小于5公分的細(xì)砂,上蓋電纜蓋板或紅機(jī)磚作為電纜的保護(hù)層。有接頭的電纜不準(zhǔn)埋在地下,接頭處應(yīng)露出地面,并配有電纜接線盒(箱)。電纜接線盒(箱)應(yīng)防雨,防塵、防機(jī)械損傷,并遠(yuǎn)離易燃、易爆、易腐蝕的場(chǎng)所。電纜干線應(yīng)采用埋地或架空敷設(shè),嚴(yán)禁沿地面明敷設(shè),并避免機(jī)械損傷和介質(zhì)腐蝕。
電纜在室外埋地敷設(shè)時(shí),必須按電纜埋設(shè)圖施工,并應(yīng)砌磚槽防護(hù),埋設(shè)深度不小于0.6米。電纜穿越建筑物、構(gòu)筑物、道路、易受機(jī)械損傷的場(chǎng)所基因出地面從2米至地面以下0.2米處,必須加設(shè)架設(shè)防護(hù)套管。地上應(yīng)由埋設(shè)電纜的標(biāo)志,并應(yīng)有專(zhuān)人負(fù)責(zé)管理。不得將物料對(duì)方在電纜埋設(shè)的上方。
