Kiosk
auto reclosers

The VX4 series of Automatic Circuit Recloser is clearly the most advanced and safe product of its kind on today's market. It is built on the well proven VX, Vacuum circuit breaker module and the FTU Recloser controller.

  • Non enclosed switch for extra safety
  • Core balance transformer for detecting low earth faults
  • Operation On and Off without electric power
  • Solid insulated. No harmful SF6 gas
  • Same footprint as ABB NAL loadbreak switch
  • Frame of stainless steel

WHAT IS ANKIOSK AUTO RECLOSER

The VX (Vacuum Interrupter module) is solidly insulated with neutral grounded stainless steel walls between the phase elements and optional integrated air break switch for extra personal operation safety. It has low weight, most of the parts are made of stainless steel and with focus on minimizing electro chemical corrosion. The bushings and isolators are made of epoxy and silicone rubber.

VACUUM INTERRUPTER MODULE (VX) BUILDING BLOCKS
The VX4 series of switch module components are a modular building system for easy tailored switches for different qualified solutions. The base is a Vacuum Interrupter Module as can take a multiple selection of options. The Air break Switch option and Earth Switch option cannot be combined on the same VX4.
 

AIRBREAK SWITCH
The air break switch gives visible open points of all three phases for extra safety. The air break switch is synchronized with the vacuum interrupter and cannot be open or closed when the vacuum interrupter is closed.

EARTH SWITCH
The earth switch is synchronized with the vacuum interrupter and cannot be closed when the vacuum interrupter is closed.

PHASE CURRENT TRANSFORMERS
The Vacuum Interrupter module can be fitted with a combination of none, two or three phase current transformers with different winding ratio and with multiple tapings.

COREBALANCE CURRENT TRANSFORMER
An addition to the phase current transformers is the core balance current transformer as measure and detect extreme low earth currents. It is suitable for all networks with isolated neutral point.
This solution gives a secure detection of extreme low earth currents as the CCT unit combines all three phases in one winding

The VX4 series are designed for use on underground distribution lines, in distribution substation, applications and as an advanced Smart Grid building block.

The FTU protection relay is fitted with multiple microprocessors and digital signaling processors for high end performance.
On top of the protection functionality, the FTU unit has also built-in RTU functionality for easy SCADA integration.
The FTU unit has built in DNP3 serial and TCP/IP and IEC 60870-5-101 serial and IEC 60870-5-104 TCP/IP and MODBUS serial /IP signaling protocol.
The VX and FTU unit can operate in complex Smart Grid application or in a single stand-alone application.

WHO NEEDS AUTO RECLOSERS?

  • Utilities who has weak network infrastructures
  • Many (SAIFI) or long (SAIDI) un-planned interruptions
  • Lifetime extension of existing network infrastructures
  • Hostile climate – Cold or Hot!
  • Many customers per km cable or very rural areas
  • Regulatory perspective – heavy fines at interruptions
  • SAIFI = system average interruption frequency index
  • SAIDI = system average interruption duration index

DISTRIBUTION SWITCHES / BREAKERSTECHNICAL DEVELOPMENT
