main feature
● The cabinet adopts an assembled structure, which is stable and reliable, and the diversified structure can be increased and expanded at one time.
● It has a unique shutter structure and good protection performance. After the load switch is opened, the shutter automatically isolates the fracture, so that the incoming bus room and the switch room are separated, repaired, and maintained safely and reliably.
● The three phases are arranged one behind the other, so the width of the cabinet is small and the floor space is small.
● The mechanical interlocking is advanced and reliable, meeting the requirements of 'five preventions'. The grounding knife of the load switch can be locked in the open or closed position with the lock, and the interlocking between the load switches can be achieved according to the program.
● It can be equipped with live display device and nuclear phase device, and the main component load switch fuse is easy to replace.
● There are two options for the operating mechanism: manual and electric. The arc extinguishing and interrupting performance is stable and reliable by using the pneumatic principle.
