Description
KYN61-40.5 High Voltage Switchgear
KYN61-40.5 high voltage switchgear is suitable for 40.5kV, three-phase, AC, 50/60Hz power grid, used for receiving and distributing electric energy, and also used for control, monitoring and protection. It is suitable for general power systems and occasions with frequent operations.
This high voltage switchgear can meet the requirements of GB3906, IEC298 and other standards. It also has "five precautions" functions such as preventing misoperation of the circuit breaker, preventing the load-carrying trolley, preventing the grounding switch from being switched on when the grounding switch is in the grounding position, preventing the grounding switch from being transmitted by the grounding position, and preventing the erroneous entry of the electric isolation.
