The main feature of KYN61-40.5KV armored moving style AC Metal-Enclosed Switchgear (hereinafter referred to as switchgear) is that the new fully insulated vacuum circuit breakers are equipped in cabinet. The cabinet body adopts assembly structure to improve the appearance quality of the product and the matching precision, assembly and timely delivery can be quickly organized to improve the utilization rate of the occupied area required by assembly and facilitate to form batch production and for other advantages. The closed-door operation can be achieved. Its various normal operation, including the switching on/off the of grounding switch, can be carried out under the condition that the door of circuit breaker room is closed. The product complied with the standards of GB3906 3-35KV AC Metal-enclosed switchgear, GB/T11022 common specification for high-voltage switchgear and controlgear and IEC60298 AC Metal-enclosed switchgear and controlgear for rated voltage about 1kv up to 52kv. The product is used for the power system of 40.5kv three phase AC 50Hz as the distribution room of power plants, substations industrial and ming enterprises to function as the acceptance and distribution of electric energy having the function of control protection and monitoring it can be widely used in general power systems but can also be used in the places of frequent operations. The operation environmental conditions shall meet the normal operation environmental conditions specified by GB3906
