自然災(zāi)害因素
配電線路在運(yùn)行的過(guò)程中,由于承載電能的特性,其在運(yùn)行的過(guò)程中會(huì)存在一定的磁場(chǎng)現(xiàn)象。此類現(xiàn)狀在遭遇雷電天氣、風(fēng)暴氣候時(shí),會(huì)產(chǎn)生一定的風(fēng)險(xiǎn)現(xiàn)象。例如磁場(chǎng)吸引,在發(fā)生雷電天氣時(shí),配電線路設(shè)備易受到雷擊危害。配電線路受雷擊危害,直接導(dǎo)致上級(jí)線路跳閘,受擊線路短路、斷路和接地故障。并且近距離運(yùn)行的電器設(shè)備,易造成線路設(shè)備爆炸或火災(zāi)現(xiàn)象。風(fēng)暴氣候出現(xiàn)時(shí),配電線路易出現(xiàn)風(fēng)偏或高桿植物造成線路跳閘事故事件,也會(huì)導(dǎo)致線路出現(xiàn)斷路或短路故障。影響了區(qū)域范圍內(nèi)用電戶的穩(wěn)定用電,并對(duì)設(shè)備的運(yùn)行狀態(tài),造成了極大的影響。
