Describe

Kyn61a-40.5 miniaturized armored gold corner enclosed switchgear is designed under the auspices of Xi'an High Voltage Power Research Institute. The cabinet frame is designed according to the metal enclosed armored movable structure, and the cabinet is equipped with a new fully insulated vacuum circuit breaker or sulfur hexafluoride circuit breaker. The cabinet adopts assembly structure, which improves the appearance quality and manufacturing accuracy and shortens the production cycle. All normal operations of the switch cabinet can be carried out when the door of the high-voltage compartment is closed. This product meets the requirements of iec-60298, GB3906, dl404 and other standards, and has the "five prevention" function of complete maintenance.

The switch cabinet is used in the 40.5kV three-phase AC 50Hz power system as the power distribution room of power plants, substations and industrial and mining enterprises to receive and distribute electric energy; The circuit has the functions of control, protection and monitoring. In addition to being widely used in general power systems, it can also be used in places with frequent operation. The operating environmental conditions shall comply with the normal operating conditions specified in GB3906 3-35kv AC metal enclosed switchgear.
