Advantages over analogues: Номинальный ток сборных шин до 2000 А Одностороннее обслуживание Малые габариты и вес при сохранении удобства монтажа и обслуживания Максимально простая реализация секционирования вводными шкафами

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: Design features KRU Vertical formed from the required number of separate cabinets by their connections during installation. Vertical switchgear cabinets have the following features: Without bolted trim design selfwedging cabinets formed sheet panels of hot dip galvanized steel, mounted on a frame of extruded aluminum profile special section; The segregation of the internal volume of the cabinet slot switching on relay protection and automation, and three high-voltage compartment: busbar (USA), a vacuum circuit breaker compartment (BB), and the cable compartment; Availability of individual relief valves in each compartment of the high-voltage cabinet, integrated into the overall system of arch protection of KRU; The possibility of dismantling / installation of current transformers in the closet feeder without removing the voltage on the busbar; Use as a switching device series vacuum switches BB / TEL-10 (1000A / 2000A and 20kA / 31,5kA); Line of sight contacts of the disconnector and earthing providing a visible break of the main circuits in the "isolated"; Air-insulated busbars; The possibility of replacing an arbitrary cabinet within a section without dismantling the adjacent cabinets; Optional application to design cabinets separate stationary linear earthing full short-circuit current (CC) for the cable connection. In the case of (according to the order) set of equipment (such as relay protection and automation) with a narrow range of acceptable operating conditions, their values ??should be taken as an appropriate range of operating conditions Vertical switchgear.

Description of the development:
()
The composition of cells Vertical switchgear has the following range of cells: Switchboards (CC), which contain a switch disconnector and earthing switch; Built-in transformer (PCS), which contain voltage transformers (IOT), a transformer of own needs (TSN) and the optional earthing busbar (ZSSH); Built-in transient (WB cabinets joints); Built-section switch (bus coupler), which contain the sectional circuit breakers and disconnectors; Built-sectional isolator (SHSR) which contain switch disconnect.
