◆ Product overview

KYN61A-40.5 miniaturized armored metal-enclosed switchgear is a new product recently designed, developed and developed by Xi'an High Voltage Electrical Research Institute. The cabinet frame is designed according to the metal enclosed armor removable structure, and the cabinet is equipped with a new fully insulated vacuum circuit breaker or sulfur hexafluoride circuit breaker. The cabinet adopts an assembled structure, which improves the appearance quality and manufacturing accuracy, and shortens the production cycle. All normal operations of the switchgear can be carried out under the condition of closing the high-pressure compartment door. This product meets the requirements of the old C-60298, GB3906, and DL404 standards, and has a perfect "five defense" function. This switchgear is used in the 40.5kV three-phase AC 50Hz power system as a power distribution room of power plants, substations and industrial and mining enterprises to receive and distribute electric energy; It has functions such as control, protection and monitoring of the circuit. In addition to being widely used in general power systems, it can also be used in places with frequent operation. The use of environmental conditions is in accordance with the normal use conditions stipulated in GB3906-91 "3-35kV AC metal-enclosed switchgear".
