Distribution FTU CPT-31

Name：CPT series reclosing controller-CPT-3 reclosing controller 1、Application The outline switch will trip off in the substation when the internal failure of 10kv overhead distribution happening, or if the failure happening in the inline section, or the prevention time of switch does not cooperate with the outline switch even if the failure happening in the inline section. If the failure is permanent, the reclosing of substation switch is not succussed, then the accident happened in the middle voltage users will cause power interruption of the whole distribution. It is very common in the distribution network and cause very bad influence in society. Boundary load switch is ideal device to solve the affected accident listed above. It is installed on the responsibility dividing point of 10kv overhead distribution network, can isolate the single phase earthing failure or short circuit between phases automatically to ensure the power safety of users not in the failure area. CPT-3 boundary load switch controller is the intelligent controller specially designed for boundary load switch. They can protect the line and communicate with center system. Controller and switch are connected by control cable and aviation connectors to protect the network and monitor it automatically. It is widely used in 10 kilovolt overhead distribution network in urban and rural areas. 2、Enviroment for Use a) Altitude： ≤2000 Meters b) Environment temperature： outdoor -40℃ ~ +80℃ the maximum average yearly temperature is 20℃, the maximum average daily temperature is 30℃
