Empowering the Future of Substations with Safer Breaker Handling
ULC Technologies and Con Edison are developing a semi-autonomous mobile robot designed to rack medium voltage circuit breakers within indoor electric distribution substations. This innovative robot is set to revolutionize field fault locating, repair, restoration activities, and circuit breaker maintenance procedures, significantly enhancing efficiency and safety.
Close proximity to breakers during the racking in and racking out process can expose workers to arc flash. Additionally, manual handling of heavy circuit breakers can also lead to soft tissue injuries. Through remote-controlled driving and autonomous operations, the Breaker Racking Robot will carry out end-to-end breaker racking and storage to improve worker safety.
Key Benefits
Improve Operator Safety
Autonomously racking in and removing breakers from cubicles to ensure operators remain at a safe distance and prevent exposure to potential arc flashes. Also eliminates the need for physical labor by effortlessly maneuvering heavy breakers.
Obstacle Detection and Collision Avoidance
Equipped with two 2D LiDAR units, the robot can detect obstacles during navigation. If an obstacle is near, the robot will automatically pause operations and the operator is notified through the warning system.
Autonomous Breaker Alignment
The Breaker Racking Robot uses Laser Profilers to detect features of breakers and cabinets and autonomously align itself from up to several feet away.
Adaptable System
The robot base platform can be adapted to operate with a wide variety of circuit breaker models and improve autonomous operations.
Convenient Charging
Battery-operated and conveniently stored in the substation’s switchgear room, the robot is always ready to assist.
Integrated Safety Features
Equipped with state-of-the-art safety features and real-time alert reporting, operators can work confidently, maintaining a consistently high level of safety.
Features
- Autonomous Racking In and Breaker Removal: A combination of actuators for manipulating levers, turning the racking nut, and pushing/pulling the breaker provides automated and safe connecting and disconnecting of the breaker with the bus.
- Wireless Control Station: The robot is controlled using a control station and wireless sub-system. The graphical user interface (GUI) provides situational awareness data, real-time camera views and push button control.
- Versatile and Configurable System: The design of the base mobile platform will allow for reconfigurability to handle several types of breakers.
Where Sparks of Innovation, Meet Safety.
Breaker Racking Robot: Process Overview
01. Autonomous Alignment
The Breaker Racking Robot utilizes 2D laser scanning and omnidirectional navigation to align itself to the breaker within the cabinet.
02. Breaker Racking Out
The breaker is racked out, lifted off the ground and secured on the frame of the robot.
03. Breaker Storage
The robot transports the breaker to a designated storage location and picks up a Ground and Test Device.
04. Breaker Racking In
The Breaker Racking Robot autonomously aligns itself to the breaker cabinet and remotely racks the breaker or Ground and Test Device.
The Circuit Breaker Racking Robot is currently developed to handle circuit breakers (1200A, 3000A, and Ground and Test Device), but can be expanded in the future to address additional types of breakers.
More Features
- Guided Breaker Alignment: The robot uses visual aids to help operators quickly align the robot with the breaker and the cubicle for precise and repeatable lifting of the breaker off the ground and cubicle insertion and removal.
- Drive System: Mecanum wheels on the robot provide omnidirectional navigation, making it easier to move in constrained environments within power stations and provide precise alignment for autonomous operations.
- Camera Sub-System: The robot is equipped with cameras for navigation, breaker identification, monitoring the racking indicator, and alignment with the cabinet. Navigational cameras minimize blind spots and provide the operator with situational awareness.
