The high-quality 11 KV Indoor Vacuum Circuit Breaker designed and produced by Youbian not only perfectly adapts to complete sets of equipment such as 11kV switchgear and ring main units, but also achieves comprehensive upgrades in breaking capacity, mechanical life, and insulation performance. With sufficient stock supply and efficient customized delivery, it has become a core cooperation partner for domestic power engineering and complete equipment manufacturers, providing hardcore support for the safe separation and integration of distribution systems.
From the perspective of product appearance and design, the 11 KV Indoor Vacuum Circuit Breaker adopts a three-phase AC 50Hz design. The main body consists of a vacuum arc extinguishing chamber, an operating mechanism, a conductive circuit, a bracket, and installation accessories. The three brown insulation sleeves clearly present the three-phase conductive circuit, and the front integrates operation buttons and status indicators such as closing, opening, and energy storage. The overall structure is compact and suitable for standardized switchgear installation dimensions.
Core technical parameters reference:
The 11 KV Indoor Vacuum Circuit Breaker adopts a high-quality vacuum arc extinguishing chamber, which has no arc overflow during disconnection, completely eliminating the fire and explosion risks of traditional oil circuit breakers and adapting to indoor dense installation environments;
The vacuum arc extinguishing chamber does not need to be replaced, and the operating mechanism uses high-quality bearings and transmission components. The mechanical life exceeds 10000 times, and only simple inspections are needed for daily operations, reducing maintenance costs;
Cooperating with relay protection devices, it can quickly cut off short-circuit faults (breaking time ≤ 0.08s), effectively protect transformers, lines and other equipment, and avoid the expansion of faults;
The 11 KV Indoor Vacuum Circuit Breaker supports the installation of intelligent controllers to achieve remote closing/opening, fault monitoring, and data uploading, meeting the upgrading needs of smart grids and distribution automation;
Standardized design is suitable for mainstream 10kV switchgear models, and can directly replace old circuit breakers, reducing renovation time and costs.
Before leaving the factory, the 11 KV Indoor Vacuum Circuit Breaker undergoes comprehensive testing including power frequency withstand voltage, mechanical life, and breaking capacity. Each product comes with a testing report to ensure 100% qualification before leaving the factory.
Zhejiang Youban Intelligent Technology is located in an industrial base with complete supporting facilities in the electrical industry. It has standardized production workshops, advanced vacuum arc extinguishing chamber assembly lines, and a comprehensive performance testing laboratory. It has established a sound ISO9001 quality management system and its products have been tested and certified by national authoritative institutions to comply with the national standard GB/T 1984-2014 "High Voltage AC Circuit Breakers". They are exported to multiple countries and regions in Southeast Asia, the Middle East, Europe, etc. With stable quality and professional services, it has become a trusted Chinese electrical equipment partner for global buyers.
Regular inspection: Check the lubrication condition of the operating mechanism and the appearance of the vacuum arc extinguishing chamber every 6-12 months. If there is no air leakage or damage, it is considered qualified;
Strictly prohibit opening and closing with load: It is forbidden to manually open and close without cutting off the load to avoid arc erosion of the arc extinguishing chamber;
Intelligent module maintenance: Install circuit breakers for intelligent controllers, regularly check communication lines and battery levels to ensure normal data transmission;
Troubleshooting: If closing fails, prioritize checking the energy storage mechanism and auxiliary switch instead of blindly disassembling the arc extinguishing chamber to avoid secondary damage.
