Air 12KV Outdoor Sf6 Load Break Switch Combined Apparatus 630A
1. Product Description of Air 12KV Outdoor Sf6 Load Break Switch Combined Apparatus 630A
FT6-12 / T630 Outdoor AC high voltage vacuum isolation load switch for outdoor three-phase AC 50Hz, rated voltage 12KV outdoor distribution system as breaking and closing load current purposes, can also be used as breaking and closing no-load circuit, no-load transformer current purposes. Meet the outdoor all-weather operating conditions, corrosion resistant, anti-contamination features.
The vacuum load switch designed and developed by our company is made. The product is compact, small size, light weight, interrupter independent structure to ensure that the process of breaking free from outside influence operations, breaking current, arcing safe and reliable; obviously isolated fracture; equipped with a special operation actuator, can be manual or electric dual operation; product basic maintenance; the load switch can be upgraded to smart load switch for distribution automation, also be equipped with a vacuum controller is upgraded to automatic slicer.
2. Structural features of Air 12KV Outdoor Sf6 Load Break Switch Combined Apparatus 630A
This switch mainly by the interrupter, isolating switch, actuator and other components. Isolation switch structure vertical rotation mode, there is no natural hazards close down, up and down through the insulator is fixed to the base frame. Interrupter by the excellent performance of vacuum tubes and manual rapid grouped brake mechanism. Fixed disconnector fixed contact side. Actuator mounted on the right inside the chassis, connected by a rod and spindle isolation switch.
