Description
FKRN 12-24D series High Voltage Air Pressure Load Switches and their combined electrical appliances are AC 24 Kv, 50 Hz indoor high voltage switch equipment, the specific technical parameters of the load switch is high, the characteristics of action, the basic form of operation mechanism is manual spring energy storage, can also be equipped with electric spring operation mechanism, based on the principle of gas pressure arc extinguishing, so it can be broken for many times, without replacing the arc extinguishing tube.
Under normal circuit condition, the high voltage load switch can turn on and off load current, carry and break load current, and has the ability to close short-circuit current and carry short-circuit current at specified time.
The FKRN 12-24D series load switch can be equipped with ground switches, which have the same short-circuit closing ability and dynamic thermal stability as the load switches, and have strict mechanical interlocking with the load switches to ensure that no misoperation can occur in the structure.
