      PCS-222 Circuit Breaker Controller
    1. The PCS-222 is an intelligent terminal used to control primary switching devices, whichinclude the circuit breaker and main transformer, in the digital substation at all voltage levels. It supports realtime GOOSE communication, and can realize tripping and closing of circuit breakers and switches by matching protection and BCU. It can locally acquire binary signals of primary equipment such as breakers and switches at the same time. It can meet the requirement of GOOSE tripping by point-to-point mode.

      The device can be installed outdoors nearby the primary equipment or connected to the protection & control devices in the control room via optic GOOSE network. Special cabinets are designed for the Circuit Breaker Controllers to fulfill the requirements of dust-proof, humidity-proof, and radiation protection.

    2. Functions Features
      • Tripping and closing of circuit breakers

      This device receives various GOOSE signals from protection devices, including tripping signals; both initial and non initial AR,and reclosing signals.Then the device drives corresponding output relays to convert GOOSE signals to output.

      • ?Remote control outputs

      This device provides 33 binary outputs. In addition to tripping/closing and blocking the outputs from the circuit breaker, it also has remote control tripping, closing and blocking contacts for four disconnectors and four earth switches.There are 24 output contacts in total.

      • ?Remote signal inputs

      This device provides 54 binary inputs. It can locally acquire binary quantities such as breaker position, switch position, and signals from thecircuit breaker mechanism and main transformer body. Then it can upload them to a corresponding protection device or BCU via GOOSE network.

      • All plug-in modules in this device can be smoothly upgraded to keep compatible with UAPC platform. Therefore, providing a solid protection for users' investment in equipment over a long period.

      • ?The device adopts high-performance DSP, internal highspeed bus, and intelligent I/O. Both hardware and software adopt modular design, allowing flexible configuration, general module for both plug-in module and software modules, and easy expansionand maintenance. Therefore, the number and types of spare plug-in modules that auser needs to keep for replacement are largely reduced.

      • ?This device can receive GOOSE signals, such as protection tripping/closing, manual closing/tripping of BCU, control of disconnecters and earth switches, and output of corresponding contacts. It can acquire and upload the position of breakers/ disconnecters/earth switches, breaker body signals, etc.

      • ?Time between receiving a GOOSE message and corresponding at output relay is less than 7ms. This is normally not affacted by a GOOSE network storm.

      • ?This device adopts fully enclosed relays, which have high impedance and low power consumption, thus power consumption and heat dissipation are reduced.Improvingthe security of the device.

      • The device provides flexible communication modes. It is equiped with 15 independent GOOSE interfaces and 1 RS- 232 commissioning port. Furthermore, it supports the new generation substation communication standard IEC61850.

      • Supporting IRIG-B synchronization via fiber optical interface and IEEE1588 time synchronization and 256 latest local operation records.

      • A ambient temperature and humidity measuringfuncionis integrated.
