Product Name: Permanent Magnet Operation Mechanism Certification: ISO9001-2000 Type: Circuit Breaker Poles Number: 3 Structure: ELCB Installation: Fixed Arc-extinguishing Medium: Vacuum Speed: High-Speed Circuit Breaker Operation: Electric Type Breaking Capacity: High Voltage Circuit Breakers Trademark: NCE Transport Package: Wooden Package Specification: compact Origin: China HS Code: 8538900000 Product Description Permanent magnet operation mechanism is a new-generation of operation mechanism which will replace spring operation mechanism in the future. It has all better and stable performance than spring operation mechanism. only the price is higher.Normally the mechanical life of permanent magnet operation mechanism can reach 100,000 times while spring mechanism usually is 10,000 times. It brings long-time maintenance free service to customer which meet the request trend of smart grid.It is much smaller, compact, less parts. These characteristics make it stable. It avoid the spring loose after several times operation.YC series magnetic actuator applies to 12/24/40.5kV voltage outdoor and indoor vacuum circuit breaker and switchgear.Actuator is designed by Yangzhou New Concept Electric Inc, and after continuous modification and marketization, it formed a variety of product serialization capabilities.Product characteristicsMagnetic actuation technique is the most advanced technique in 90th century. It adopts a new kind of working principle and organization, by combining electromagnet and permanent magnet, it realizes full functions of traditional circuit breaker operation mechanism. In structure, the biggest difference between magnetic actuator and traditional circuit breaker operating mechanism is that it can realize traditional function of end position of mechanism without the need to remove and lock the device, and has fewer moving parts(only one), lower power consumption, high reliability and maintenance-free.Magnetic operation mechanism mainly consists of permanent magnetic and open/close control coil, and is a new type of electromagnetic operation mechanism using permanent magnets to achieve vacuum circuit breaker closing and opening hold.Traditional circuit breaker normally use spring operation mechanism, consists of more than 100 parts, transmission system complicated, mechanical lock, more friction surface, more lubrication parts, large volume, high failure rate and short life.Permanent magnetic mechanism, only has 7 spare parts, 1 moving part, without mechanical wear, stable and reliable, no need periodic maintenance, and mechanical life more than 100k times.Permanent operation mechanism has following advantages:Less spare parts, only one removable part, no mechanical wear, increase mechanical reliabilityMechanism's mechanical life can be more than 100k times, compared to traditional electromagnetic mechanism and spring mechanism, mechanical life increases more than 3 times.Simplify transmission line by driving moving contact through moving iron core, eliminate the need for mechanical removal and locking devices, reducing the source of fault. The use of magnetically actuated (permanent magnet) mechanism can greatly reduce the number of components, greatly reduce the closing power, and is stable and reliable, without regular maintenance. Reliable guarantee of circuit breaker sequence [O -t1(0.3s)-CO-t2(180s)-CO-Lock] successfully completed.
