New Concept Electric Inc.  

Product Name: Permanent Magnetic Operation Mechanism Permanent Magnetic Actuator for Switchgear Model NO.: NCE-PM-12-01 Certification: ISO9001-2000, CCC Function: Conventional Circuit Breaker, Circuit-Breaker Failure Protection, Overcurrent Protection, OVP(Overvoltage Protection), RCCB Type: Circuit Breaker Poles Number: 3 Structure: Vcb Installation: Fixed Arc-extinguishing Medium: Vacuum Speed: High-Speed Circuit Breaker Operation: Energy-storage Type Breaking Capacity: High Voltage Circuit Breakers Operating Power: DC110V/220V/380V Trademark: NCE Transport Package: Wooden Package Specification: customized Origin: China HS Code: 8538900000 Product Description Permanent Magnetic Operation Mechanism Permanent Magnetic Actuator for SwitchgearYC series of permanent magnetic mechanism (magnetic actuator) is used in 12/24/40.5kV voltage level of indoor and outdoor vacuum circuit breakers and RMU, as a prototype of New Concept Electric Inc independent research and development, through continuous structural optimization and marketing, forming a multi series of products supporting capacity. Less components, simple structure, high reliability, long life (mechanical life of up to 100,000), maintenance-free, can be used to control electronic software, so its prospects are very broad, permanent institutions can be divided into one-shot permanent magnet means and bistable permanent magnetic actuator; by number of used coils, divided into two-coil permanent magnet means and the single-coil permanent magnetic means.Technical parametersNo.nameparameterRemark1Operating PowerDC110V / DC220V / DC380VDemand can be customized2Co-bit static holding force> 3000NSupporting 20kA circuit breaker or RMU> 3500NSupporting 25kA circuit breaker or RMU> 4200NSupporting 31.5kA breaker or RMU3Travel agencies8-35mmDemand can be customized4Mechanical life> 100,000 times/5Temperature demagnetization> 175 ºCDemand can be customized6Inherent in opening time<10msTo 10kV equipment as an exampleNew Concept Electric Inc is an integrated manufacturer of switchgear and vacuum circuit breaker. We are not only an assembly factory but also a manufacturer of many parts. Operation mechanism, epoxy resin insulator, control panel, circuit board, structure, etc.Permanent magnetic mechanism is an important part of operation mechanism. Its market percentage increases quickly in past years. NCE permanent magnetic mechanism adpots the advanced solution to make. It uses three single-phase permanent magnetic mechanism. It is more stable and reliable than spring mechanism because it has less parts. Its closing power is increasedenormously.Adopt fast algorithm with national patent technology (patent number: ZL200720037710.7) so as to obtain fast breaking capacity for circuit breaker. As a result, it can isolate fault circuit rapidly. If we take 12kV circuit breaker as an example, it takes less than 25ms from inspecting fault to cut out fault circuit. It can avoid the problem of override trip effectively.Adopt single-phase grounding protection system with national patent technology (patent number: ZL201020178325.6). It can realize online judgment to single phase grounding fault of low current grounding system without adding device. Releases warning or tripping action according to setting valueApply the most advanced embedded operation system currently; adopt dual CPU structure, including ARM9 for general processing and system control, and strong DSP with high efficiency processing on multitasking; and realize high speed data processing, control and communication.It has function of automatic re-close which can effectively prevent power outage caused by instantaneous fault. The power distribution network could also complete fault isolation and power restoration automatically without cooperation of main station.Convenient operation, either manual open/close operation, or wireless remote operation. The remote distance is more than 50m.Adopt synchronous open/close technology so as to realize synchronous open/close of circuit breaker and restrain overvoltage and inrush phenomenon effectively.Permanent magnetic operation mechanism is used in our products in many projects for years. And it get good reputation from our customers. We continuously provide good quality permanent magnetic mechanism for the customers and switchgear factories.NCE passed ISO9001:2015, ISO14001:2015 and OHSAS 18001:2007 certificates and the CCC certificate.We wish to cooperate with current and new customers for long cooperations.
