Product Description
Complete switchgear with withdrawable elements of the KYN61-40.5 series (hereinafter referred to as the “switching device”). Its main feature is the use of a fully insulated ZN85-40.5 vacuum circuit breaker and spring actuator in the cabinet. The body is made of powder-coated steel sheets, which increases the precision of the cart's mating with the body, ensuring ease of rolling in and out of the cart and high interchangeability. The device is distinguished by its aesthetic appearance, wide range of circuits and reliability in operation.
The product consists of two main parts: the body and the trolley. The body is made from bent, powder-coated steel sheets, assembled using bolts. According to functional characteristics, it is divided into four compartments: the auxiliary busbar compartment, the relay equipment and measuring instruments compartment, the trolley compartment, the cable compartment and the busbar compartment. Each compartment is separated from the others by grounded metal partitions. The degree of protection of the outer shell of the housing is IP4X; when the trolley compartment door is open, the degree of protection is IP2X. This device provides the main circuit diagrams: cable inputs/outputs, air inputs/outputs, busbar sectioning, insulation, voltage transformers, surge suppressors and others. Busbars have combined insulation; Interphase connections and connections at the inputs are equipped with insulating caps cast from flame-retardant material. Between adjacent cabinets, the main busbars are separated by insulating sleeves, which effectively prevents the spread of accidents and at the same time serves as additional support for the main busbars. The cable compartment is equipped with a grounding switch, surge protection device and other equipment.
