  一、概述
  I. General Information
  上为电气有多年零序电流互感器的生产经验,质量优于国际GB1208-1997《电流互感器》,产品分整体式和组合式两类,互感器采用工程塑料外壳,树脂浇注成全密封。外形美观、安装方便、节省安装空间,规格品种多,可适应各种保护装置的需要,和电力系统各种运行方式(中性点接地、中性点不接地、大电阻接地、小电流接地、消弧线圈接地)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、选型
  II. Model Selection
  Type
  Inner bore diameter (mm)
  Combined type (Open type)
  Zero sequence current transformer
  Shangwei Electricity
  类别说明:
  Illustration of types:
  A  表示配合小电流接地选线装置使用
  B  表示配合DD11/60型继电器配合使用
  C  表示配合DL11/0.2型继电器配合使用
  D  表示配合消弧线圈、微机保护、小电阻接地系统使用
  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:本公司根据用户要求制作特殊孔径产品。
  Note: The company can produce products with special bore diameters as per users’ requirements.
