HUGHES KIOSK RECLOSERMAIN ADVANTAGES

The VXR kiosk recloser of the latest generation has the following advantages:

  • Low maintenance. Hughes reclosers are built to remain in operation for more than 30 years without major maintenance due to the highest quality materials used in its construction. 
  • Live tank construction (1). It completely eliminates the occurrence of internal arc faults and the risk of explosion or destruction inside the recloser switch tank. That makes it repairable in case one of the poles is damaged. It provides improved cooling of the vacuum interrupters due to unhindered air circulation. It has the increased creepage distance that allows the use of reclosers in an environment with a 4th degree of atmospheric pollution and cleaning of insulation without dismantling;
  • Solid epoxy insulation of bushings and insulators is environmentally friendly, does not contain harmful SF6 gas or oil;
  • Vacuum interrupter bottles that can handle 25kA faults for 3s guarantee long term problem free operation in networks with many high current faults;
  • Highest quality stainless steel (2) is used for most of the parts to minimize electrochemical corrosion. The use of stainless steel in accordance with DIN50049 / 3.1B, thanks to its non-magnetic properties, completely eliminates the occurrence of any kind of corrosion, including electrochemical corrosion over the entire life of the recloser;
  • Spring stored energy operating mechanism provides turning On and Off the switch module even in the complete absence of power supply (voltage transformer malfunction, full battery discharge);
  • Manual charging (3) of the spring mechanism as well as switch operation On and Off are possible with the help of manoeuvring arms located on a switch body. The spring capacity is enough for the full reclosing cycle (Off - On - Off);
  • Padlock facility (4) for mechanical blocking of operation;
  • Advanced protection relay with functions of directional fault detection, low earth fault detection, intermittent earth fault detection, automatic reverse power flow setting change;
  • Same footprint as ABB NAL load break switch;
  • Truck mount (5) for simple maintenance; optional
  • Simple connection to the bus bar (6) or cable (several custom options);
  • Simple installation in existing switch bays and kiosks;

RECLOSER USERS

         
          Utilities with:
  • weak network infrastructures;
  • multiple (SAIFI) or long (SAIDI) unplanned 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 for interruptions;
  • SAIFI = system average interruption frequency index
  • SAIDI = system average interruption duration index

HUGHES KIOSK RECLOSERBUILDING BLOCKS

VX4 vacuum circuit breaker
The VX4 series of vacuum circuit breaker is a modular building system, enabling to build easy tailored switches for different qualified solutions.

The basic VX4 can have the following built-in optional components.
