KYN61-40. 5 Armored Removable Indoor Metal-Enclosed Switchgear is suitable for three-phase AC 50Hz, rated voltage 40.5kV single bus and single bus segmented power systems. It is widely used in power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories, mines and high-rise buildings. It is used to receive and distribute electric energy, and control, protect and monitor the circuit, meeting the requirements of IEC 298, GB3906, DL/T 404 and other standards.

Product introduction:

●  Reasonable use of composite insulation, optimization of electrode shape, improvement of electric field distribution and other measures make the entire cabinet structure compact and effectively reduce the floor space;

●  The "five-protection" functions are complete and the operation is safe and reliable. A mechanical interlocking device is installed between the trolley, circuit breaker, grounding switch and the rear door of the cabinet to prevent misoperation. At the same time, a padlock can be installed on the valve push mechanism to prevent accidents caused by non-professionals opening the valve by mistake when the trolley exits the cabinet;

●  The circuit breaker, grounding switch and other operations can be carried out under the condition that the cabinet door is closed, and closed-door operation is fully realized;

·  The cabinet is made of high-strength, corrosion-resistant imported aluminum-zinc plate processed by CNC sheet metal, and connected by high-strength bolts and nuts, and rivet nuts. The entire cabinet has no welding, precise size, good rigidity, and ensures the interchangeability of the trolley;

●  The ball screw push mechanism is adopted, which makes the trolley push (exit) both labor-saving and stable;

● Simple operation and convenient maintenance. Users can master the operation method and understand the precautions through the instruction manual without special training.
