Product Description
FZW28F-12/630 Series outdoor users boundaries vacuum load switch

1. Product Description:
        When 10kV distribution line T connected internal user fails, as its fault line side, or failure in the line but the inside of the switch protection operation time and substation outlet switch with no protection at that time, will result in the protection of substation outlet switch off brake.
        If the nature of the fault is permanent, substation coincidence unsuccessful, a pressure accident will result in the user community within the entire power distribution lines, even single-phase ground will cause interference to other users, which in the distribution network common accident spread to other normal users unnecessary power loss, highly dependent on the power supply to the adverse effects of social.
        Boundary load switch is the ideal equipment to solve the spread of the accident, the responsibility of the demarcation point of the equipment installed in the 10KV power distribution lines, can be automatically removed single-phase ground fault isolation and automatic phase fault. To ensure the safe use of electricity and to prevent the user's non-fault accident user failure to expand.
        Boundary load switch control device is designed for intelligent control of the switch body boundaries. Implement protective control functions and other functions, the control device and switch body via a control cable and air connectors for electrical connection to achieve its automatic monitoring and protection functions, the product is widely used in urban and rural users 10KV power distribution lines.
