The CHZ4(T)-12(15/27/38) KV/630A-1250A Providing the features of a traditional re-closer, plus the bene of up to date design optimized for automation, remote control and monitoring, now or in the future.by customer demand for improved return on capital investment in the distribution network to achieve optimum performance and reliability, making use of the latest available technology in insulation, vacuum interruption and microelectronics.
Three phase pole-top automatic circuit re-closer are designed and produced by the three kind of international advanced technology, as epoxy solid encapsulated technology, permanent magnetic actuating device, and intelligence control technology and so on.
The product is composite with solid dielectric insulted pole, permanent magnetic actuating device or motor actuating device, control unit, current transformer and vacuum interrupter and voltage sensor. Except the control unit is a single device, the others are combined together, compact frame, flexible design, easy to operate.
The CHZ4(T)-12(15/27/38) KV/630A-1250A three phase pole-top automatic circuit re-closer is for 12kV(15KV/27KV/38KV),50/60Hz distribution system, has not only circuit breaker control and protection features, but also can automatically detect the lines running statement.
Once the load side line or equipment occur a fault, meet or exceed current setting the minimum starting current, it will be good at a per-determined action sequence, to identify the fault is transient or permanent, and auto-complete one to three re-closing.
