Muhimman Iyakoki
Babu SF6 gas design, zafi da zero burden: Ta yi karfin SF6 greenhouse gas insulation media, babu fitaccen gas da za suka faru a cikin aiki, yana daidaita na siyasa ta biyu na carbon da kuma talabukan zafi, da kuma bai canza waɗanda suke da kyau a kan cost of compliance and rectification risks of SF6 equipment.
High performance vacuum arc extinguishing chamber, long-term protection equipment: Amfani da vacuum arc extinguishing components na musamman, arc extinguishing response speed is fast, which can quickly cut off the arc, greatly reduce the erosion loss of conductive contacts, extend the life of equipment core components from the root, and reduce the frequency of maintenance and replacement.
High reliability operating mechanism, zero opening and closing errors: Customized and stable operating mechanism with high action accuracy and fast response speed, ensuring that each opening and closing operation is completed quickly and effectively, avoiding operational failures from the source, and ensuring the continuous operation of the distribution system.
Can type sealed structure, suitable for complex working conditions: adopting a fully sealed tank design, it has excellent dustproof, moisture-proof, and anti pollution performance, and can operate stably in complex outdoor/indoor environments such as high temperature, high humidity, and high dust.
Low operation and maintenance costs, high long-term cost-effectiveness: low loss rate of core components, low risk of failure, significantly reducing manpower and capital investment in spare parts replacement and on-site maintenance, and reducing long-term usage costs by more than 30% compared to traditional equipment.
Wide adaptation current range, strong scene compatibility: supports multiple rated current selections of 2000/3150/4000A, and can flexibly match high-voltage distribution systems of different capacities without the need for additional customization and adjustment.
Kwayoyin aiki
RVD vacuum high-voltage tank circuit breaker mainly consists of the following core components:
Vacuum arc extinguishing unit: Equipped with a high-performance vacuum arc extinguishing chamber, integrated with conductive contacts and insulating supports, it is the core module for achieving rapid arc extinguishing;
Sealed tank: It is sealed and packaged with high-strength metal material, with a vacuum insulated environment inside and an insulated sleeve (spiral structure in the picture) on the outside for external wiring;
Operating mechanism box: integrated stable operating mechanism, control components, and status display device, installed below the tank, responsible for receiving instructions and driving opening and closing actions;
Supporting frame: Using steel structure brackets with high-strength load-bearing performance, the equipment can be stably fixed to the installation foundation, while reserving space for operation and maintenance.
