Unit-type Modular SF6 Ring Net Cabinet - High Voltage switchgear
Contour & Installation size - High Voltage switchgearStructure (metal) - High Voltage switchgear
The cabinet is double-bended by the 1.5/2.0mm thick aluminum- zinc steel plate, which is light and solid. All components are connected by rivets or screws. The cabinet rear is pressed by the cover board and supported by the rivets below. In this way, in case of accident we can make sure that the leasing gas is released from the rear. The cover board on the cabinet is fixed by M6 screw. The cabinet gate is of special design so that it can bear possible pressure released by internal breakdown caused arc burning. It can be lifted and make anti-clockwise rotation by the gate handles. The small standard auxiliary components chamber on the upper cabinet can install terminal strip and other secondary parts. If the small chamber was lifted, the relay and other parts can be installed. Interlock load switch and grounded switch are automatic. Grounded switch and the interlock between the cabinet gates are mandatory. Do as the following steps to achieve automatically interlock. Close the cabinet gate. Open the grounded switch and close the load switch. Separate operation mode can effectively avoid misuse.
