Nuclear reactive load, abbreviated as NRL, is a kind of special protection device for electric power system. It is suitable for fault current limitation and protection of important equipment. The 0451008.NRL is a type of fuse with multiple applications, such as existing transmission and distribution systems, substations, telecommunication systems, and data processing centers. This article will focus on the application field and working principle of 0451008.NRL.The 0451008.NRL is mainly used for protection of busbar, generators, transformers, and switches. It provides advanced fault current limitation and overcurrent protection for the power system. It is mainly used in the protection of large and medium sized power systems with high voltage and large capacity, including (but not limited to) urban power supply systems, industrial and mining power systems, wind and solar energy power systems, generators, and transformer stations. It can also be used in the protection of urban power supply, booster stations, transformer substations, large and medium sized diesel generating sets, trans-provincial transmission lines, and various power equipments.The working principle of the 0451008.NRL can be explained with the help of a diagram. When a current passes through the fuse links, the heat generated by the current breaks down the adhesive between the fuse link parts, thus causing the fuse’s main element to melt and disconnect the electric circuit. In this way, the system can be effectively protected from overcurrent and short circuit damage due to the thermal effect of long-term heavy current passing through the fuse system. When a fault occurs, the current passes through the fuse, and the heat generated will cause the fuse link to break, thus disconnecting the electric circuit. In this way, the electric circuit is effectively cut off, preventing damage to other equipment in the system. The 0451008.NRL also provides additional protection against faulty wiring by eliminating the risk of short circuit and overload. The fuse protects the power system by responding quickly to the fault current, reducing the operating temperature of the electrical components, and limiting the magnitude of an electrical shock. In addition, fuses reduce the risk of fire due to short circuits, improve the safety of people and equipment, and reduce insurance premiums. In conclusion, the 0451008.NRL offers a high degree of protection to power systems due to its fault current limitation and over-current protection. It is suitable for the protection of many large and medium-sized power systems and can effectively prevent short-circuits, overloads, and other malfunctions. Moreover, its use in power systems can also prevent unnecessary fire risks and promote safety for personnel and equipment.
