The Usune VS1 Indoor Vacuum Circuit Breaker is a core protection device specifically designed for medium-voltage indoor power distribution scenarios. It is widely used in circuit control and power protection in critical locations such as substations, industrial plants, commercial buildings, and residential power grids.
Compared to traditional oil-immersed and SF6 circuit breakers, the Indoor Vacuum Circuit Breaker utilizes vacuum arc-extinguishing technology, eliminating open flames and harmful gas emissions, resulting in higher operational safety. Equipped with an integrated spring operating mechanism, its precise and stable operation effectively solves problems such as easy aging, frequent failures, and frequent maintenance associated with traditional equipment, making it the preferred device for modern intelligent power distribution systems.
Custom-developed for indoor power distribution environments, adaptable to normal temperature, humidity, and space conditions, allowing for long-term stable operation in enclosed indoor power distribution scenarios with strong environmental adaptability.
Adopting a modular integrated design and optimized internal structure, the overall unit is small in size and lightweight, significantly saving installation space in the power distribution room, making it suitable for space-constrained commercial and industrial power distribution scenarios.
Equipped with a high-precision integrated spring operating mechanism, ensuring precise and consistent opening and closing actions. It boasts strong resistance to voltage fluctuations and environmental vibrations, resulting in an extremely low equipment failure rate.
Utilizing a high-quality vacuum interrupter, its electrical lifespan far exceeds industry standards. It eliminates the need for frequent replacement of vulnerable parts, enabling long-term maintenance-free operation and significantly reducing subsequent maintenance costs.
Optimized mechanical transmission structure reduces wear during opening and closing, making it suitable for power grid peak shaving and high-frequency start-stop scenarios in industrial production lines. It withstands frequent operations and offers high work efficiency.
Its dimensions, installation interfaces, and electrical parameters are fully matched with KYN28 switchgear, allowing for seamless assembly and rapid installation, facilitating project construction and subsequent equipment upgrades.
A residential power grid renovation project in an area of East China adopted Usune VS1-12kV Indoor Vacuum Circuit Breaker in batches, used in conjunction with KYN28 switchgear in community substations. This residential area experiences concentrated power load and frequent peak-hour switching. The product's superior performance in frequent operation and rapid fault disconnection completely solved the problems of frequent tripping and unstable power supply in the aging power grid. The equipment has experienced zero failures in its first year of operation, effectively ensuring the safety and stability of residential electricity supply.
This product covers three mainstream voltage levels: 12kV, 24kV, and 36kV. It is compatible with 50/60Hz AC indoor medium-voltage power distribution systems and is widely applicable to indoor substations, industrial workshops, commercial buildings, high-rise residential buildings, community power grids, etc., comprehensively meeting the power protection and circuit switching needs of industrial production, commercial operations, and residential life.
The product can be seamlessly matched with the KYN28 series switchgear, ready to use immediately, and is also compatible with most mainstream indoor medium-voltage switchgear on the market. For customers' existing special equipment models, our technical team can provide customized parameter debugging and installation solutions to ensure the compatibility and stable operation of the entire equipment.
The Usune VS1 indoor vacuum circuit breaker is equipped with a high-quality vacuum interrupter and an integrated spring mechanism, enabling long-term maintenance-free operation under normal conditions. Routine maintenance only requires periodic simple dust removal and checking of operating status. Unlike traditional circuit breakers, there is no need for regular parts replacement and lubrication, greatly saving maintenance time and costs.
