The intelligent integrated power supply system consists of AC power supply, DC power supply, AC uninterruptible power supply, DC converter for communication, inverter power supply and general monitoring unit; DC power supply, AC uninterruptible power supply (UPS), inverter power supply (INV) and communication DC / DC share the same set of batteries, which reduces the number of batteries and reduces the operation and maintenance and management costs. The general monitoring unit implements centralized monitoring and decentralized control for each power subsystem, which improves the management level of integrated power supply system.
GZDW series DC power supply cabinet is suitable for large, medium and small power plants and substations. It is used as the operation power supply for opening and closing, relay protection, automatic device and signal device of DC operating mechanism of high voltage circuit breaker, and DC power supply for emergency lighting and control.
Atsun is the only supplier of nuclear safety high frequency switching power supply in China. In the field of nuclear safety level power system, with its strong R & D and innovation ability, OTEX has become a member of "CGN nuclear power equipment localization research and development center". The nuclear power products researched and developed not only meet the requirements of nuclear power plant operation with high quality, but also break the long-term monopoly of foreign countries on such products, saving a lot of costs for the construction and operation of nuclear power plants in China, and promote the development of nuclear power plants in China The process of localization of nuclear power equipment. Nuclear safety class (1E) high frequency switch DC charging device and DC distribution cabinet refer to the 2008 nuclear power plant 1E high frequency switch DC charging device and AC / DC distribution cabinet prototype qualification test program, and combined with the opinions of relevant experts, OTEX compiled the quality appraisal program (version a) of 1E high frequency switch DC charging device and DC distribution cabinet, and passed the Nuclear experts have reviewed it. The charging device is composed of 4 charging cabinets and 1 incoming cabinet. The rated output current of the charging device is 1200A and the maximum output voltage is 286v. 39 atc230m32 charging modules are distributed in four single charging cabinets. The DC distribution cabinet is composed of battery feeder cabinet and battery fuse switch cabinet. There are frame type switch, drawer switch, fuse, indicator light, signal, wiring terminal, horizontal bus bar and vertical bus bar. There are two drawer type cabinets in total. Acp1000 PWR nuclear power plant 1E AC / DC power distribution cabinet in July 1999, CNNC started the conceptual design of 1 MW PWR nuclear power plant. After more than ten years of hard work and the joint efforts of the old, middle and young generations of CNNC people, acp1000, a third generation PWR nuclear power brand with complete independent intellectual property rights, has been developed. Acp1000 design comprehensively and balanced the design principles of nuclear safety defense in depth and design reliability. 177 sets of fuel assemblies are used in the core. The double containment, single reactor arrangement and "safety design concept of combining active and passive" are adopted in the core. The passive safety system which can effectively deal with the loss of power source is taken as the supplement of the engineering proven, efficient, mature and reliable active safety system, which provides diversified means to meet the safety requirements. China's nuclear power equipment Co., Ltd
It passed CPR1000 certification in 2008, epr1250 in 2012, Hualong No.1 nuclear safety product in 2015, and acp1000 in 2015
The structure of atcj type AC power supply system is divided into incoming line unit and feed unit. The cabinet structure has fixed type, drawer type and fixed partition type. The product has passed the type test of the national authoritative testing organization and obtained the China Compulsory Product Certification Certificate (3C certificate), which conforms to iec60439 and GB 7251.1-2005 standards. It is widely used in industrial and mining enterprises, substations, high-rise buildings and other power distribution places.
