Product overview
KYN61-40.5 (Z) armored open type AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a three-phase cross-flow 50H2, rated voltage 40.5kV indoor complete power distribution equipment. As a power plant, substation and industrial and mining enterprises to accept and distribute electricity, the circuit to play a control, protection and monitoring functions, can also be used for frequent operation of the place.
Product characteristics
- Reasonable use of composite insulation, optimize the shape of the electrode, improve the electric field distribution and other measures, so that the entire cabinet structure is compact, effectively reducing the footprint.
- Five-proof" function is complete, safe and reliable operation, handcart, circuit breaker, grounding switch and the cabinet back door is equipped with a mechanical interlocking device to prevent misoperation, at the same time in the valve propulsion mechanism can be added padlock, to prevent the handcart out of the cabinet, due to the non-professional personnel mistakenly open the door and cause accidents: circuit breakers, ground switches, and other operations can be carried out under the conditions of the closure of the cabinet door, fully realize the Closed door operation.
- The cabinet is made of high-strength, corrosion-resistant imported zinc aluminum-zinc plate formed by CNC sheet metal processing, connected by high-strength bolts and nuts, pull rivet nuts, the whole cabinet is no welding, precise size, good stiffness, to ensure interchangeability of the handcart.
- Adoption of ball screw propulsion mechanism makes the trolley propulsion (withdrawal) both labor-saving and smooth.
- Simple to operate, easy to maintain, the user only through the use of the manual will be able to master its operation, and can understand the precautions, no need for specialized training.
