1,Summary PCZ-12 ~38kV (we called it CHZ series before) Series Reclosers is a new generation of multi-function product developed and manufactured by Zhejiang Pleased Electric Co.,product employs advanced technology throughout the whole design. It integrates the functions of control,protection,measurements,communication,fault detection,on-line monitoring of closing or opening. It can carry out Substation Automation and distribution automation．This product can be used as the switches in 10kV up to 38kV line and 10kV up to 38kV outline of distribution. It can be also used as the switches in poll,It is suitable choice to realize distribution automation and miniaturization Substation. 2,Technical Features

● Uses imported outdoor Compound silicon rubber for insulated material．The device has light weight,long life and is able to endure hash outdoor climate . It has no oil or gas, environmentally friendly.

● Advanced DSP is used in this system. The device integrates the functions of control,protection ,measurement and communication.

● The device uses the integrated sensor technology and can be monitored and measured on-line.

● The circuit-breakers can be closed or open in-phase. This can restrain over -voltage and surge current in operation effectively. This feature has special advantages with capacitors

● Rich Communication methods. The recloser can communicate through GPRS modem and support English or Chinese short messages.

● There are 128 sampling points in a cycle. FFT transform provides high-speed and high-precision data up to 19th harmonics waveforms.

● The device has good EMC compatibility. Its EMC meets IV level of the Chinese national standard. It ensures the recloser not to act by accident.

● The device can provide independent phase tripping current protection when it communicated to each other with optical cable,This feature ensures the device to have fault isolation or resume power supply automatically without the centre station. This greatly improves the reliability of power supply.

● The device measures and makes corrections according to the temperature inside. This feature made it to have high precision throughout the entire operating temperature range.

● The specially designed power supply unit can switch between AC110V and AC220V，The voltages of the batteries can be tested and the charge current or voltage can be controlled.

● User interface is very friendly. It supports Chinese&English.

● The stainless steel cabinet does not rust and made the device essentially maintenance free. 3,Main Functions

● Protective Function:This device has instantaneous over-current protection,timing over-current protection,negative sequence over-current protection,directional over-current protection and over-voltage protection.

● Measurement：The recloser can measure currents,voltages,kWh,kVARh,power factor and frequency etc.

● Control：The recloser can be controlled locally and remotely. The control sequence can also be pre-programmed

● Automation：The recloser can implement fault detection,fault isolation,power supply resume and parameters analyse automatically. It can subtract load automatically in low frequency and deliver or cut capacitors automatically. It can report failure in time through GPRS modem or other communication network.

● Communication：The recloser provides TCP/IP，DNP3.0，IEC101 protocols. CAN,RS232/485 ports are available and make the recloser ready for external links through a GPRS modem.

● The recloser can record and save the operation parameters and failure parameters. The protected values and parameters can be set locally or remotely.

● The mechanism parameters of the recloser and the operation status of the vacuum interrupters can be monitored on-line.

● The circuit-breakers can be closed or opened in-phase. This can restrain over voltage and surge current in operation effectively especially for capacitors 4,Technical Parameters
