Acrel published "Atlas of Smart Motor Control and Protection Secondary Circuits"

Smart Motor Protector is a new type of smart protector using modern electronic technology, communications technology, and computer network technology. The protector has motor overload, phase failure, underload, stall, blocking, three-phase imbalance, overvoltage, undervoltage, underpower, over temperature, start overtime, residual current, power phase sequence and other protection and operating data Remote and monitoring functions. The protector can play an active role in the effectiveness of the motor protection, operation and maintenance and management, equipment safety and fire protection, energy conservation and consumption reduction, in order to promote the application of new technologies and meet the needs of engineering designers, construction workers, and supervisors. The Atlas was compiled.
Atlas combines the characteristics of the ARD series products, designed the motor directly start circuit diagram, the motor forward and reverse start circuit diagram, the motor two-speed starting circuit diagram, the motor star-delta starting circuit diagram, the motor auto-coupling decompression starting circuit diagram, the motor soft start protection circuit diagram, One-for-one, one-for-one, two-start motor control, two mutual preparation, liquid level control and mutual preparation circuit diagram, electric valve electrical control circuit diagram, sewage pump, submerged pump, belt conveyor, conveyor belt and other control circuit diagram. The atlas was compiled by engineers such as Lu Weiqing, Zhao Bo, and Li Yingxin of Shanghai Ankerui Electric Co., Ltd. Li Daoben Senior Engineer, Li Binghua, and Duke Gao worked on this atlas carefully.
The atlas can be used by metallurgy, petrochemical, coal, light industry, and industrial enterprise power distribution systems to engage in electrical design, scientific research, manufacturing, construction, installation, supervision, operation, and maintenance personnel reading, but also for power supply and power professional Design, scientific research, installation, operation and maintenance personnel and teachers and students of relevant professional universities read.
