OPERATING MECHANISM AND SWITCH
"The spring operating mechanism equipped in the high-voltage ring main unit is a supporting device for 12kV rated voltage AC metal-enclosed switchgear. This series of mechanisms uses a planar volute spring for energy storage to control the operation of the load switch, while the earthing operation uses a compression spring over-center energy storage control. The operating positions include three positions: closing, opening, and earthing. The series features five-prevention interlocking functions, a compact size, easy installation, and strong adaptability.
