General Description   KYN 61-40.5 Removable AC metal-clad switchgear (short for switchgear as below) applies to 40.5KV, 3 phase, AC and 50/60HZ electrical power network for receiving and distributing power energy and also for control, monitor and protection. It is applicable in general power system and occasions with frequent operation. The product conforms to GB 3906 “3-35KV AC Metal Enclosed Switchgear”. GB/T 11022 “The common technical clauses of HV Switchgear and controlgear Standard”, DL/T 404-1997 “Order Technical term of indoor AC HV Switchgear” and IEC-298 1-52KV “AC Metal Enclosed Switchgear and controlgear standard”         Model Definition       Operating Condition Ambient temperature: -10°C-40°C; Altitude: ≤3000m Relative humidity: daily average≤95%, monthly average≤90%; Earthquake intensity: ≤8 degree; Applicable occasions should be free from corrosives, inflammables and vapour.       Design Feature The switchgear is an assembly unit and the circuit breaker adopts handcart floor model. It owns simply change and well exchange after equipping with advanced composite insulation vacuum circuit breaker. Lead screw nut propulsion mechanism is installed in the handcart frame for preventing from fault operating and damaging propulsion mechanism, the handcart can be remove easily; all of the operation steps can be carried out at closing condition; it is compulsory locking among main switch, handcart and panel door to meet five protection; wide space for connecting several cable in cable cubicle. Earthing switch is used in earthing and loop short circuit, protection degree of enclosure is IP3X, IP2X under operating condition.       Technical Parameters

      Structure Feature The switchgear divides into enclosure and handcart, the enclosure is made of aluminum-zinc plated steel sheet after processed by CNC machine and multi-bending, then is assembled with blots. So it has strong mechanical strength and can guarantee the neatness and good appearance. Is consist of relay compartment, handcart compartment, cabledegree is IP2X when CB handcart is on opening and testing position.   The switchgear is metal-clad removable, main circuit adopts composite insulation processing, emergency spreading to other parts. CT and earthing switch are mounted in cable compartment and busbar compartment. The protection degree of enclosure is IP3X, the protection and large space for several cables. The structural design of new completely insulated VCB or SF6 CB and spring operating mechanism is integrated console model with such excellence of well exchange and simply change.       Company Information   Dongturbo Electric Company Ltd headquartered in Chengdu, Sichuan, and workshop for switchgear located in Kunming, Yunnan.
