Breaker Remote Racking Device for Magne-blast Switchgear

The remote racking equipment from Power Precision allows viewing and connecting breakers from a safe distance – outside the arc flash boundary.

 

Touch screen operator interface

  • Breaker movement is controlled by a touch screen graphical interfac
  • The controls prompt the operator through a sequence of steps and checks to perform the racking process safely. 
  • The control interface is mounted safely outside the arc flash boundary.
  • Real time information such as the breaker tilt/level measurements and breaker lifting resistance are displayed in real time.
  • Alarms and faults are displayed immediately.

 

Live Video Monitoring

  • Using a low light Infra-red camera, the operator is able to view the breaker position and movement on a live flat screen video monitor while the breaker door is closed. 
  • The video monitor is mounted next to the operator interface outside the arc flash boundary.

 

Breaker Tilt Monitoring

  • A dual axis analog monitor continuously transmits breaker the level/tilt status of the breaker for live viewing and to automatically stop movement when outside programmed limits.

 

Breaker Lift Resistance

  • The resistance of the breaker lifting mechanism is continuously monitored.  Resistance exceeding typical limits provides an alarm or trip.

 

Lifting Motor and Controls

  • A new racking motor/clutch assembly is provided to control the motor, clutch and breaker lifting mechanism from the remote operator station.
  • The new racking motor/clutch assembly is equipped with a variety of sensors for monitoring during operation.

 

Previous versions have involved portable controls as shown below.
