With the growth of electricity demand, people have begun to propose the idea of establishing an electricity production center. The development of motor manufacturing technology, the expansion of the scope of electric energy application, and the rapid growth of the demand for electricity in production have led to the emergence of power plants. At present, power plants can be divided into many types according to different power generation modes: Fossil fuel power station, hydropower plants, solar (photovoltaic) power generation, wind power generation and tidal power generation. Faced with a variety of power generation and distribution systems, the final step in the power system - facing end users - is the final step in the distribution system. Therefore, the improvement of the distribution system directly affects the reliability and quality of electricity consumption for the majority of users, and therefore plays an important role in the power system.
The SVO series products have been used in many large power plants in previous engineering cases, such as the first phase of Shandong Longda Thermal Power Project, the later stage renovation of Hongyang Thermal Power, the new construction project of Hunjiang Power Plant, and the renovation project of Changdian Station of Taipingwan Power Plant. Therefore, in the application of the power industry, Shenyang SVO electrical products have become very mature.
The main application products in the Shandong Longda Thermal Power Phase I project include SIWOG series isolation switches and SIWOQ series dual power supply products. In response to the requirement of not allowing power outages during the operation of important equipment in the project, the SIWOQ1-3 series PC grade dual power supply products were adopted in the design. By accurately judging and converting the status of the power supply during the operation of the dual power supply product, the normal power supply and operation of equipment in the project are ensured. The SIWOG series isolation switch products, as the main power isolation switches, are mainly used for power isolation in various distribution cabinets and boxes in power plants, and are all equipped with padlock functions to ensure the personal safety of maintenance personnel during maintenance.
The SIWOP and PCESIWO series products were applied in the later transformation of Hongyang Thermal Power. In response to the harsh environment of high dust or high corrosion in the coal conveying system and desulfurization workshop of the thermal power plant, imported materials were used in the project, with IP protection levels ranging from IP44 to IP67 for PCESIWO industrial plugs and sockets and SIWOP maintenance box products. The products have many advantages such as dust prevention, water resistance, corrosion resistance, high mechanical strength, and stable protective functions. In practical applications, it has received high praise from users, ensuring the stability of electricity consumption and safe operation of equipment in thermal power plants.
The new project of Hunjiang Power Plant has designed and applied multiple types of products, including SIWOE series intelligent instruments, SIWOQ series and SIWOT6 series automatic transfer switches, and SIWODK motor protectors. For many large loads and important distribution circuits in power generation equipment, SIWO has launched the power level automatic transfer switch SIWOT6 series products. Its high short-term withstand capacity, extreme short-circuit breaking capacity, rapid conversion time, and intelligent and networked detection and control system provide reliable guarantees for the safe and stable operation of important loads in power plants. In addition, SIWOQ series automatic transfer switches are used, Provide reliable power supply for various loads ranging from 16A to 4000A in the factory.
The SIWODK product is applied to the water control system in the factory. SIWODK has 13 monitoring and protection functions and 9 startup control methods, meeting the application requirements of various equipment in the water treatment system. The design concept of intelligence and networking also meets the automation requirements of power plant construction.
The renovation project of Changdian Station in Taipingwan Power Plant has designed and applied products such as SIWOQ series automatic transfer switches, SIWOG isolation switches, and PCESIWO industrial plugs and sockets.
The SIWOQ series products, as the flagship products of SIWO Company, rely on their excellent product quality to be applied in the factory lighting system and fire equipment control system in this renovation. The SIWOG series products are used as power isolation switches in the power distribution system of this project, and are installed in distribution cabinets and boxes at all levels.
