Portable Remote Racking Assembly for Magne-Blast Circuit Breaker

Touch screen operator interface

• Breaker movement is controlled by a touch screen graphical interface.
• 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. 
• Two different options are available for remote controls and video monitoring
  • A large video monitor above the touch screen controls in a permanently wall mounted cabinet - shown below
  • OR a portable monitor and control station in an orange industrial case - shown below

Breaker Tilt Monitoring

• A dual axis analog monitor continuously transmits 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.
