獨家|電網脆弱元凶曝光 三接超高壓電纜竟降低標準驗收
4.完整新聞內文:
近年全台各地無預警停電、跳電事故頻傳,凸顯台電供電能力、穩定性不足,不但民怨四
起,也重創國內外企業投資信心,《蘋果新聞網》接獲台電人員爆料,指台灣電網脆弱元
凶之一,竟是台電長年放任綜合研究所降低電纜耐壓試驗標準,甚至連國人關注的大潭天
然氣三號接氣站,正進行大潭電廠連接林口電廠的超高壓電纜工程,都企圖以十多年前的
暫時替代方案降低標準驗收,不依國際標準及台電自訂規範進行全段耐壓試驗。
台電人員指出,各發電廠的電力必須透過電網進行輸送配電,而大大小小電網就是透過各
條電力電纜連接組成。電力電纜出廠前須通過定型試驗(Type Test) 、例行性試驗
(Routine Test) 及取樣試驗(Sample Test),以確保電纜的品質。
此外,根據IEC(國際電工委員會)及台灣電力公司的標準,電力電纜現場安裝完成後,還
必須進行各項現地竣工試驗(Acceptance test),如:電氣試驗、耐壓試驗、部分放電試
驗、系統加壓24小時….等,確認電纜最終狀態符合驗收標準,才能併聯加入供電系統。
然而,台電公司參考IEC國際規範所制訂的竣工耐壓試驗標準,長期以來卻「嚴以待人、
寬以律己」,要求民間廠商執行耐壓試驗必須完全符合國際標準,但對於台電綜合研究所
為台電各項工程進行驗收,卻大開後門,2010年以設備不足為由,提出「暫時替代方案」
,自行降低驗收標準至今,結果不但阻礙我國對於高壓試驗技術的提升與產業發展,也無
法為電纜工程品質把關,恐成為近年電網脆弱的元凶之一。
以新建電纜為例,國際、中國及台電的電力規範,耐壓試驗標準都要求「指定電壓下進行
全段耐壓1小時」,台電卻放水同意旗下綜合研究所執行「暫時替代方案」,不但將耐壓
時間減半至30分鐘,還可將電纜切成多段,只要分段進行耐壓試驗,就可通過驗收。
離譜的是,只有台電綜研所可以執行「暫時替代方案」,民間廠商承攬台電標案,一律都
要依照國際規範,通過全段耐壓1小時試驗,否則台電不予驗收。
更可議的是,分段耐壓試驗不但需追加大筆分段工程費用,將電纜切除分段後安裝測試用
套管引出,嚴重影響工程進度,且分段試驗完畢之後,又再用電纜接續閘將電纜接回,結
果最常發生事故的「電纜接續匣」,並未在全段耐壓試驗時同時進行測試,勢必提高日後
電網事故風險。
台電內部人員進一步爆料,近年備受國人關注的「大潭天然氣三號接氣站」,政府規劃擴
充大潭電廠發電機組來大幅提升發電量,目前正進行大潭至林口電廠超高壓電纜工程(總
共規劃四迴線12條,每條長達31.3公里的161kV超高壓電纜),台電綜合研究所依然不顧
電網安全,想要以分段耐壓試驗、降低標準驗收,甚至要求輸工處為分段試驗追加編列約
2000萬套管材料等費用,連台電其他部門都看不下去。
台電內部人員認為,想要有安全穩定的電力,除了依靠政府長遠規劃多種能源政策提高發
電量、提升同仁專業職能,也要確保電網系統安全、可靠,才能將意外風險降至最低。因
此呼籲主管機關正視相關電力試驗積弊,才能確保供電安全。
