12kV 24kV Outdoor Pole-Mounted Recloser 630A 20kA
12kV 24kV Outdoor Pole-Mounted Recloser 630A 20kA (VCB) is a three-phase AC 50Hz power distribution equipment with a rated voltage of 12kV. Designed for outdoor use, it serves as reliable protection and control equipment for substations, industrial power distribution systems, and rural power grids with frequent operations.
This circuit breaker features compact size, lightweight construction, anti-condensation properties, and maintenance-free operation. It is engineered to withstand harsh weather conditions and polluted environments while maintaining optimal performance.
Structural features
◆ The vacum arc extinguishing chamber adopts patented solid sealing technology,small sze,long life,high reliabiliy,exposed shielding cover; encapsulated in epoxy resin,good weather resistance,easy to transport operation mechanism using high reliability bistable permanent Magnetic technology,simple structure,no maintenance,mechanical life can be up to 30,000 times;
◆ Epoxy resin wax package:mets environmental protection requirements:has been widely verified outdoor performance:ozone and ultraviolet resistance;strong,light and not easy to break;
◆Permanent magnet mechanism:few moving parts;no maintenance is required;bistable permanent magnet technology is applied;
◆Vacuum arc extinguishing,solid insulation,small size,light weight,large breaking capacity and high insulation level;
◆ Manual opening device:when the control system fails,manual opening can be used for emergency breaking operation,which can reliably break the rated load current;
◆ Position detector:the proximity switch is installed on the linkage shaft,no mechanical components are needed,and the sub-station position of the switch is simply and reliably detected;
◆ The shell of the switch is made of stainless steel or spray plastic,which has good corrosion resistance and weather resistance;
◆ Isolation switch,forming visible fracture and reliable interlocking,forming a combined electrical appliance;
◆The controller realizes "four remote"functions of remote control,telemetry,remote signaling and remote adjustment.
