Innovations in electrical engineering have led to cutting-edge technologies that revolutionized power distribution systems. One notable advancement is the solid insulated core unit. This blog aims to illustrate the performance benefits of this technology and its key components, including vacuum interrupters, solid insulation systems and three-station knife gates. Let’s get into the details!
1. Vacuum arc extinguishing chamber:
The core of the solid insulated ring main unit is the vacuum arc extinguishing chamber, which is equipped with a vacuum circuit breaker. This component has excellent short-circuit current breaking capabilities while ensuring overload and short-circuit protection of circuits and electrical equipment. Vacuum circuit breakers operate efficiently with minimal contact opening distances, short arcing times and low operating energy requirements. In addition, it has the characteristics of small size, light weight, waterproof, explosion-proof, and low operating noise. With its remarkable characteristics, vacuum interrupters have widely replaced oil circuit breakers and SF6 circuit breakers and are used in various industries.
2. Solid insulation system:
The solid insulated ring main unit adopts solid-sealed poles produced by the advanced pressure gel (APG) process. These poles contain important current-carrying conductors such as the vacuum interrupter and upper and lower exit seats, forming a unified unit. This solid insulation system is the primary method of phase insulation. By implementing the isolating switch within the solid sealing rod, wireless expansion of the functional units becomes possible. Design flexibility also enables single-phase busbar scalability, facilitating seamless upgrades and adaptability of distribution systems.
3. Three-station knife gate:
Three-station knife switches are used in all switch cabinets, which is a major feature of the solid insulated core unit. The knife switch is integrated into the sealing lever together with the main switch. Additionally, it enables three-phase linkage, ensuring smooth operation and facilitating effective circuit breaking when required.
As we explored the various components of solid insulated core units, it became clear that their performance advantages surpassed traditional alternatives. These benefits include enhanced safety, compact size, reduced maintenance, improved energy efficiency and reliable performance. In particular, the solid insulation system simplifies expansion possibilities, allowing the seamless integration of additional functions according to changing needs.
As technology continues to advance, solid insulated core units will play a key role in shaping the future of power distribution systems. Industries such as power generation, metallurgy and communications have already experienced the advantages of these advanced equipment. Employing this sustainable smart solution increases productivity, protects valuable electrical equipment, and ensures the efficient flow of power.
In summary, solid insulated core units are a major breakthrough in power distribution technology. With key components such as a vacuum interrupter, solid insulation system and three-station knife switch, the solution offers enhanced safety, increased energy efficiency and versatile expansion possibilities. As industries continue to adopt this innovative solution, solid insulated core units will redefine the future of power distribution systems.
