~1. General description
This Series indoor high voltage motorized earthing switch (short as: motorized earthing switch) is designed for the intelligent switchgear requirement of the electric system. It is suit for 3~40.5KV, 3 phase, AC 50 (60) Hz power system and kinds of high voltage switchgears. It is applicable for high voltage switchgear arrangement as the earthing protection when maintenance.
Due to the earthing switch is electrically operated, the cabinet manually operated interlocks is still keep the same as original design, but there are some parts have been modified, be sure to use our company's matchable connection rod , otherwise it would be burned the motor of motorized earthing switch.
Since the earthing switch is electrically operated, and therefore the cabinet manually operated chain catching rabbits consistent with the original style, but there are some parts have been modified, be sure to use the matching connection rod of our company, otherwise it would be burned the motor of motorized earthing switch.
If the cabinet back door need interlocking with motorized earthing switch, also be sure to use the company's patented technology to produce backdoor interlock mechanism, and equipped travel switch.
When the back door is not closed, cutting off the operation power of motorized earthing switch to avoid motorized earthing switch of misuse and damage the motor.
When electric interlocking with the motorized earthing switch, be sure to use auxiliary contacts associated with electrical components to disconnect the operation power of the motorized earthing switch to achieve electrical interlock in order to ensure a reliable electrical interlock.
