1.General description

VACF12-24kV series M.V. air type load break switch and its combination apparatus are used for AC 24kV, 50Hz indoor M.V. switchgear. The specific technical parameters of the load switch are high and the action is reliable. The operating mechanism is basically formed as manual spring energy storage type, and it can also be equipped with electromagnetic spring operating mechanism. Based on the principle of air pressure arc extinguishing, it can be broken many times without replacing arc extinguishing tube.

Under normal circuit conditions, the M.V. load switch can turn on,carry and turn off load current, and has the ability to turn on short-circuit current and bear short-circuit current at a specified time. M.V. load switch is suitable for installation in ring network switch cabinet and other types of switch cabinet for receiving and distributing electric energy.

VACF 12-24kV series load switch can be equipped with grounding switch. The grounding switch has the same short-circuit closing capacity as the load switch, so as to enable and dynamic thermal stability, and has strict mechanical interlock with the load switch, so as to ensure no misoperation in structure.

M.V. load switch is suitable for installation in ring network switch cabinet and other types of switch cabinet for receiving and distributing electric energy.
