Paglalarawan ng Produkto
Bilang isang bagong henerasyon ng pangunahing kagamitan para sa distribusyon na espesyal na disenyo para sa 145kV tatlong-phase AC sistema, ang RVD vacuum high-voltage tank circuit breaker ay may "SF6 free environmental protection technology+high-performance vacuum arc extinguishing+high stability operating mechanism" bilang core nito, sumisira sa mga limitasyon ng tradisyunal na tank circuit breakers. Ito ay maaaring umadapt sa mahigpit na high-voltage distribution scenarios at lumikha ng matagal na halaga para sa mga user mula sa perspektibo ng environmental protection, operation and maintenance, at seguridad. Ito ay kasalukuyang ang pinakamagandang solusyon para sa pag-upgrade ng high-voltage distribution systems sa mga substation, industrial plants, at iba pang lugar.
Pangunahing Katangian
Walang disenyong SF6 gas, berde at zero burden: Abandoning traditional SF6 greenhouse gas insulation media, walang masasamang paglabas ng gas sa buong proseso, na sumasabay sa dual carbon policy at environmental protection requirements, at walang kailangan na magdala ng environmental compliance costs at rectification risks ng mga kagamitang SF6.
High performance vacuum arc extinguishing chamber, long-term protection equipment: equipped with high-quality vacuum arc extinguishing components, ang bilis ng tugon ng arc extinguishing ay mabilis, na maaaring mabilis na putulin ang arc, malaking pagbawas sa erosion loss ng conductive contacts, pag-extend ng buhay ng core components ng equipment mula sa ugat, at pagbawas sa frequency ng maintenance at 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.
Struktura ng Produkto
Ang RVD vacuum high-voltage tank circuit breaker ay pangunahing binubuo ng mga sumusunod na core components:
Vacuum arc extinguishing unit: Equipped with a high-performance vacuum arc extinguishing chamber, integrated with conductive contacts and insulating supports, ito ang core module para sa pag-achieve ng mabilis na arc extinguishing;
Sealed tank: Ito ay sealed at nakapackage sa high-strength metal material, may vacuum insulated environment sa loob at may insulating sleeve (spiral structure sa larawan) sa labas para sa external wiring;
Operating mechanism box: integrated stable operating mechanism, control components, at 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, ang kagamitan ay maaaring maayos na fixed sa installation foundation, habang nagrereserve ng space para sa operation and maintenance.
