RPW auxiliary switchgears

The Guaranteed Auxiliary Power Supply System was designed to ensure reliable and uninterrupted supply of devices in case of an interference or a power failure in the power network.

 

Areas of Guaranteed Auxiliary Power Supply Systems application

  • Professional power sector: substations
  • Heavy industry: metallurgy, fuel and energy, shipbuilding, defence
  • Public buildings

 

A basic variant of a guaranteed auxiliary power supply system consists of:

AC 400 / 230 V switchgear

  • single-, double- or multi-selective system,
  • two or more power sources including energy measurement systems
  • overvoltage protection, class B and C
  • output circuits, single- and three-phase, protected with fuse-switches or overcurrent circuit breakers with response monitoring
  • control and measurement equipment

 

ATAS switchgear

  • automation module for selecting the operating mode (spinning and operating reserve), as well as a diagram of switches
  • coupler, contactor or moulded-case circuit-breaker
  • LCD graphic display
  • set of buttons and switches for manual control

 

DC 220(110)V switchgear

  • single-, double- or multi-selective system
  • ZP industrial power supply
  • battery protection
  • temperature compensation system
  • measurement of current for battery charging
  • control of battery circuit integrity
  • battery voltage measurement
  • measurement of earth fault resistance
  • LED reduction system
  • output circuits protected with fuse‑switches or overcurrent circuit breakers with response monitoring

 

AC-GW switchgear

  • FPS guaranteed voltage inverter with integrated electronic bypass
  • service bypass
  • output circuits protected with fuse‑switches or overcurrent circuit breakers with response monitoring
  • galvanic isolation between the DC circuit and output circuits
  • control and measurement equipment

 

Battery switchgear or battery rack with connection set

  • type and parameters of the batteries individually matched to the demand for power and back-up time
