產品簡介

(中興電工)公司自民國七十三年八月開始與日商日立製作所技術合作,產製SF6氣體絕緣開關設備(GIS)SF6氣體絕緣複合式開關設備(GCS)SF6氣體絕緣斷路器(GCB)

與本公司技術合作之日立製作所,對GISGCSGCB等設備之設計、製造是從西元1969年開始,故對上述設備已俱豐富實際經驗。145 kV SF6氣體絕緣斷路器(Live Tank GCB),係由3個包封於充滿SF6氣體的瓷礙子內之滅弧室(CB)、支持瓷礙子(Support Insulator)、彈簧操動機構(Spring Mechanism)、控制櫃(LCC)、台架等組成。

CB可以控制櫃中的切換開關轉換為就地控制或遠方遙控室中控制。而於維護時須將切換開關置於就地(LOCAL)位置,只允許就地能夠操作控制。
