DC Switchgear

PowerBond™

BRUSH PowerBond™ DC Switchgear is an innovative solution designed to meet the demands of the world’s busiest transit systems. Utilising our award-winning magnetic actuator technology, PowerBond™ is an all-in-one solution, combining the functionality of a line circuit breaker with that of a bonding switch.

Overview

Developed for today’s modern rail network, PowerBond™ is an air-insulated, air-break, high-speed direct current circuit breaker which allows direct current contact line systems to be fed from the traction power supply, or alternatively to be bonded to negative or earth.

Designed for 750V DC and 1500V traction power systems, both overhead line and conductor (3rd and 4th) rail, PowerBond™ is compatible with a wide range of protection relays, including BRUSH Switchgear Mitre+.

With all this functionality in one unit, PowerBond™ offers a smaller footprint, convenience of installation, safe maintenance and superior performance.

NDC circuit breaker at the heart of Lightning DC

The patented arc transfer system prevents internal contamination of the circuit breaker compartment and cubicle.

The cold cathode arc chute assembly dissipates all arcs whilst the transfer coil provides additional magnetic flux across the contact gap, assisting with the interruption of low currents that would otherwise lead to long arcing times.

The magnetic actuator is based on a solenoid plunger, and provides the motion required to close the main contacts and to reset the latch device on tripping.

SafeBond

SafeBond integrates the feeder circuit breaker function and the remote bonding function into one standard Lightning panel footprint, a big advantage in floor space saving, civil engineering, cabling and operational consistency and safety.

Overview

SafeBond incorporates the NDC high speed, unidirectional circuit breaker, featuring the award-winning magnetic actuator, to carry out the making and breaking of all load and fault currents, whilst an ‘off-load’ motorised two position disconnector selects the circuit.

With the disconnector in the positive position and the NDC circuit breaker closed, the positive busbar is connected to the track feeder cable thereby functioning as a standard feeder circuit breaker.
