Current transformer installation
Please back out the outer surface of current transformer, suspe nd the current transformer with rope on 3 spots without stow-wood, put the current transformers into the sleeve in the light of negative pola rity(the letter P1 on the upside of CT as its nameplate stands uprigh t),set the current transformer with its secondary lead on the same di rection as the secondary lead box, and finally fix the current transfo rmers. 4.2接线及检查 将电流互感器的二次接线端子正确、牢固地接在二次出线板的接线柱上，并标明 出线标志，接线完毕后应做极性和变比检查。对于小变比（100／5A以下）电流互 感器变比检验用电流法测量可能误差较大，推荐采用校验仪检验。 Lead junction and examination Secondary leads should be connected firmly with secondary termina ls marked. Current ratio and polarity examination tests are carried ou t after secondary lead connection. For the current transformer with sm all current ratio(less than 100/5A), checkout instrument should be sug gested to test current ratio as error of current measurement method. 5．注意事项 电流互感器的铁芯材料为硅钢片及合金等磁性材料， 猛烈的敲打及撞击会对磁 性能产生很大的影响，因此，严禁搬运时将互感器在地上滚动，装配固定时严禁 猛烈敲打电流互感器。

套管型电流互感器 Bushing Current Transformer 使用说明书 Explanation for Use
Packaging and storing
Please pack current transformer with plastic film bag and put them into wooden box which should be strong enough to be able to protec t current transformer from being damaged. In addition, they should be stored at dry and ventilative place. 订货时请提出产品型号、电流比、额定负荷、准确级、外形尺寸等要求， 有特殊要求时在订货时提供技术协议。 7．订货须知
1．用途 套管型电流互感器用于交流电力设备上，用于电气测量和继电保护。 Application Bushing current transformers are applied on AC electrical equipme nts for measuring and relay. 2．分类 套管型电流互感器按其用途，可分为测量级互感器和保护级互感器两种。 Class Bushing current transformers may be divided into measuring transfo rmers and relay transformers according to their purpose. 3．型号说明 Ty器外观及铭牌数据逐一检查，确保各参数符合使 用要求；将检验合格的电流互感器按照不同型号分类摆放（摆放时将铭牌正 立），在120℃烘房内干燥24小时。 Installation The appearance and nameplate of every current transformer shoul d be checked to assure the parameters to be able to meet the requi rement for use. Please put the current transformers checked accordi ng to their type(nameplate up) in 120℃ drying room for 24 hours.
4.1电流互感器的安装 拆除电流互感器的外保护层，采用三点起吊的方法，用绳子起吊电流互感器 非垫块部位，依据电流互感器装配顺序，按减极性方向（产品铭牌正立时上端面 为P1）逐一装配到套筒内，装配时注意电流互感器二次引线与套筒二次出线盒在 同一方向，并用适当的方法将电流互感器固定。
Notice
Knocking and impacting violently the core of current transformer m ay possibly influence greatly magnetic performance because the core is made of silicon steel or alloy. So, rolling or impacting the cur rent transformer is forbidden. 6．包装和储存 电流互感器用薄膜塑料袋密封包装后装入木箱中， 木箱具有足够的机械强 度，可保证电流互感器在运输中不受损伤；产品应放置在干燥通风处储存。
