Overview
The VJY1 indoor AC vacuum circuit breaker (Here in after referred to as breaker) is a three-phase AC 50Hz 12KV indoor switchgear, which is available for the control and protection purposes for electrical installations of industrial and mining enterprises, power plants and substations, and is suitable for the places that require frequent operation.
Description
Features
The VJY1 indoor AC vacuum circuit breaker, the nylon enclosed column is adapted in the arc chute. Comparing with traditional air insulated column, the breaker has following advantages:
• the technical performance of solid insulation embedded column is higher than GB/DL Standards.
• Easy structure design, less dismountable components, highly reliable.
• Advanced and energy-saving manufacture technologies have been adapted, light and eco-friendly material.
• New generation insulating material has been adapted; Extremely high insulation ability.
• Extremely high mechanical strength, the longitudinal pulling force can reach to 10000N.
• Adapting the latest and newest automation molding technology (APG Molding Technology), which is highly stable and reliable.
• Safe and Reliable, maintenance-free.
Mechanical Features
• The storage transmission of VJY1 is gear transmission; and the release device is swing-type leverage. The common structure of VS1 is very loose. The release device move radially, which requires higher accuracy, otherwise, there are some possibilities of stuck, open failure and early release.
• Due to the overall modular layout, the common vacuum breaker adapted Four-link Structure.
