Descriptive Bulletin R-MAG magnetically actuated dead tank outdoor vacuum circuit breaker 15.5 kv - 38 kv
Introduction The R-MAG is truly the next generation in medium voltage vacuum circuit breaker technology. ABB is the first to combine the unique benefits of vacuum interrupter technology with a magnetic actuator designed to exploit these capabilities. Using a flux-shifting device with integral permanent magnets, the R-MAG mechanism has only one moving part. With simple open and close coils, an electronic controller and capacitors for energy storage, the R-MAG circuit breaker mechanism is capable of 10,000 load operations. These are a few of the features that mark a departure from the conventional spring-operated mechanism, introducing new capabilities and benefits for a smarter distribution system. ABB makes safety our first priority by employing magnetic actuators to eliminate maintenance on coils, motors, and mechanically charged springs. R-MAG benefits include: Simple, less frequent maintenance Rated for 10,000 full load operations (five times ANSI requirements) No maintenance required on magnetic actuator Plug & play actuator circuitry Vacuum interrupters rated for 30,000 full load operations Increased reliability Magnetic actuator has only one moving part No spring charging motors to replace No trip/close coils to replace Less moving parts leads to less maintenance R-MAG increased performance 2,000 operations between servicing vs 500 operations between servicing - ANSI C37.06 requirements 10,000 mechanical or load operations vs 2,000 no-load mechanical operations - ANSI C37.06 requirements No maintenance required on magnetic actuator Eliminates open/close coils in stored spring mechanism lubrication requirements The R-MAG has three main components: Vacuum interrupter assembly Operating mechanism Provides reliable operation even after extended periods of inactivity Electronic control board Compatible with all forms of overcurrent, reclosing and control functions 2 R-MAG magnetically actuated dead tank outdoor vacuum circuit breaker Descriptive bulletin

Magnetic actuator ABB has utilized magnetic actuators since 1997. One global team is dedicated to designing magnetic actuators for ABB products, including R-MAG breakers. 15 kv rated at 100,000 mechanical operations 38 kv rated at 50,000 mechanical operations One moving part No maintenance required Magnet life expectancy Developments in magnetic material technology allow the magnetic actuator to be highly reliable over a long life time. Reduction in magnetic flux density is less than 1% over 100 years at 248 F (120 C). Connection to cranksfaft Coils Permanent magnets Movable armature Steel laminate housing A spring charged mechanism has over 300 total parts (many moving parts) and requires periodic maintenance. A magnetic actuator has one moving part and requires no maintenance. 4 R-MAG magnetically actuated dead tank outdoor vacuum circuit breaker Descriptive bulletin
All operating mechanism functions are integrated in the magnetic actuator of the R-MAG circuit breaker. The actuator is a bistable magnet system, in which armature change-of-state is accomplished by the magnetic field of two electrically excited coils. The armature is held magnetically in the limit positions by the fields of two rare-earth permanent magnets. Switching operations are achieved by excitation of one of the two coils until the retaining force of the permanent magnets is exceeded. Even after complete failure of the auxiliary power, the energy stored in the capacitors will allow electrical operation for 200 seconds. In the event of complete loss of control power, the circuit breaker can be tripped manually. The armature of the magnetic actuator is linked to an operating shaft connected via insulated push rods to each of the vacuum interrupters.
