  一、概述
  I. General Information
  上為電氣有多年零序電流互感器的生產經驗,質量優于國際GB1208-1997《電流互感器》,產品分整體式和組合式兩類,互感器采用工程塑料外殼,樹脂澆注成全密封。外形美觀、安裝方便、節省安裝空間,規格品種多,可適應各種保護裝置的需要,和電力系統各種運行方式(中性點接地、中性點不接地、大電阻接地、小電流接地、消弧線圈接地)的需要。
  Shangwei Electricity has many years of experiences for producing zero sequence current transformers. The quality of our products is better than those specified in the national standard GB1208-1997 Current Transformers. The products are divided into integrated type and combined type. Engineering plastic casings are used for such transformers, and resin is poured into fully sealed packages. The products have nice appearances; they can be easily installed and they can save installation spaces. The various specifications can meet the requirements of all kinds of protective devices as well as all kinds of operation modes (neutral point grounding, neutral non-grounding, large current grounding, small current grounding and arc suppression coil grounding) in electric systems
  二、選型
  II. Model Selection

  B  表示配合DD11/60型繼電器配合使用
  C  表示配合DL11/0.2型繼電器配合使用
  D  表示配合消弧線圈、微機保護、小電阻接地系統使用
  A stands for that it is used for small current grounding line selection devices
  B stands for that it is used for DD11/60 relays
  C stands for that it is used for DL11/0.2 relays
  D stands for that it is used for arc suppression coil, microcomputer protection and low resistance grounding systems
  注明:本公司根據用戶要求制作特殊孔徑產品。
  Note: The company can produce products with special bore diameters as per users’ requirements.
