Insulation design of low voltage and heavy current busbar and its application
低壓大電流母線的絕緣設計與工程應用 -
In 2004, the company s technology development department has actively and successfully developed the shield - type american - style european - style cable heads, high - low - voltage cable branch cases for load switch busbar coupler system, outdoor ring network cabinets, box - type transformer substations and auxiliary products, which have passed the authentication one after another and been launched into the market in large batches, giving a strong support to the upgrading of the national urban power grids and the construction of key projects ; in 2006, the company has developed the four - splitting and dual - splitting wire and cable box and released to market ; the 2nd half of 2006, over 500kv ultra - high voltage electrical hardware being developed for 2007 market ; four products awarded national patents in 2006
2004年公司技術開發部積極開發了屏蔽型美式歐式電纜接頭，負荷開關母線聯接系統的高低壓電纜分接箱，戶外環網櫃，箱式變電站及配套產品相繼通過鑒定，大批量投入市場，有力支持國家城網改造與重大工程建設2006年公司又研製出四分流二分流電線電纜分線盒，已投放市場2006年下半年，正在研製開發超高壓500kv及以上電力金具，有望2007年投放市場2006年有六種產品已申請國家專利。 -
At present the special protective devices for busbars in middle and low voltage distribution networks are still not common. only appended to original busbar protections, so the faults occurred in middle and low voltage busbars have to be cleared by back - up relaying with long time delay. thus, some kind of faults may spread which originally could be cleared and tremendous economy loss may appear
在電力系統中35kv及以下電壓等級的母線由於沒有穩定問題，一般未裝設專門母線保護，母線故障要由較長延時的后備保護來切除，使不少本可以得到控制的故障被發展和擴大，造成了巨大的經濟損失。 -
