India Portugal Overview With a 20 years’ experience using vacuum technology, Efacec used the know-how for the development of three-phase REVAC circuit-breakers, where the breaking and switching environment is vacuum. This technology is particularly adjusted to functions of this type of reclosing equipment, enabling more switching manoeuvres, helping the device to be more stable and useful in power distribution networks. The device is environmentally friendly with vacuum switching technology and SF6-free insulation creating added-value for the management of smart power grids. The REVAC was designed to integrate an automated power distribution system. Reliability on distribution network is enhanced when integrating this equipment. Failures can be detected and isolated by the device and the network can be reconfigured from the control centre or based on distributed intelligence. This type of technology enables to increase the service quality and to reduce the cost associated to outages and line-crew dispatch. The switchgear is equipped with magnetic actuator, current transformer, resistive voltage sensores, controller, devices for protection, communication and remote control. Benefits • Flexible • Reliable • Remotely controlled • Long service life (10 000 mechanical operations) • Ideal for adverse environmental conditions • Compact equipment design • Simple and flexible installation • Adapted to any type of pole assemblies • Few mechanical parts, minimal maintenance • Prepared for smart automation of distribution networks Construction Features Bushing The equipment is a three-phase device, each phase with a corresponding vacuum interrupter and with Voltage Sensing epoxy resin housing. Each pole has it’s own magnetic actuator interconnected by a mechanical link that assures synchronized three phase operation. An external pull lever enables manual tripping of the device. Current Sensor The signalling of state position is on the REVAC lid and it is visible by the operator from the ground. Voltage is measure by six terminals of the device using resistive sensors, and the current is measured in all phases by toroidal transformers. Designed for outdoor operation (pole-mounted) REVAC circuit breakers are insensitive to weather Magnetic Actuator conditions, easily assembled with straightforward operation.

Includes breaker control with multiple reclose cycles, voltage check and optional synchronism check as a part of the available function set, in addition to sectionalizer / interrupter controller. Fault Detection and Protection Functions The RCU 220 supports several independent stages for main fault detection and protection functions, such as ANSI/IEC standard curves, traditional recloser curves, and editable time-current curves. Eight independent setting groups are available. Feeder Automation The RCU 220 can be easily integrated in radial or loop network configurations and includes a flexible loop section isolation and feeder restoration function that implements a distributed self-healing algorithm (that can be further enhanced with peer-to-peer GOOSE messaging). The RCU 220 units are capable of automatically adapting the control algorithms to the new network topology through flexible settings. Recording, Measurement and Monitoring The RCU 220 includes a general-purpose event and disturbance recorder; all records are stored in native COMTRADE format. The RCU 220 also includes a fault location function and extended fault reporting. The unit provides six voltage inputs and four current inputs, enabling continuous monitoring upstream and downstream of the recloser. Three-phase measurements and metering are some of the built-in monitoring functions. The RCU 220 also includes the fault location function and extended fault reports. Hardware The RCU 220 was designed according to European and US international standards, and tested by independent laboratories. This product is also CE Marked according to the applicable European Directives. The RCU 220E cabinet, with protection level of IP55, includes all necessary components for recloser application, including batteries, inverters, battery system monitoring and management function, communication interfaces and I/O wiring.

  • Outdoor Circuit Breaker GVR Recloser Hawker Siddeley Switchgear
    Outdoor circuit breaker GVR Recloser Hawker Siddeley Switchgear rated voltage 15, 27 and 38 kV rated current 630 A Outdoor circuit breakers GVR Recloser GVR switchgear brings the reliability of modern materials and technology to overhead distribution networks The reliability of a system is achieved through: a new, patented, single coil magnetic actuator mechanism which allows the GVR to operate independently of the HV supply and to be tested in an ordinary workshop; environmentally friendly vacuum interruption produces no by-products; the lightweight aluminium tank makes the GVR easier to transport and install; the EPDM rubber bushings are resistant to damage from vandalism or mishandling; by extensive use of insulated mouldings, in particular the bushings, the total number of parts has been reduced by a factor of x 20 and the number of moving parts by x 50. Environmental design The award-winning GVR gas-filled vacuum recloser combines the high reliability of vacuum interruption with the controlled environment and high dielectric strength of SF6, in a compact, maintenance-free unit. Since SF6 is only used as insulation, there is no health hazard from toxic by- products of arcing. Electrical life is well in excess of ANSI and IEC requirements. The magnetic actuator provides consistent performance and a dramatic reduction in the number of moving parts. Materials and finishes have been carefully chosen for reliability – from EPDM bushings, tested for tracking and erosion to IEC 1109, in salt fog and other environments, to the neodymium iron boron permanent magnets used in the mechanism. Application The GVR can be pole mounted or substation mounted and can operate as a stand-alone recloser without the need for an additional auxiliary supply, or it can be integrated into the most advanced distribution automation schemes.
