Air-insulated secondary switchgear up to 12 kV KSO-423 «Omega»

Air-insulated secondary switchgear up to 12 kV KSO-243 "Omega" are used for receiving and distributing three-phase alternating current electricity with a frequency of 50 and 60 Hz in networks with an isolated or grounded neutral.
AIS KSO-243 "Omega" cells are used in:
- indoor switchgear units (ISU) of complete transformer substations (CTS);
- electrical substations of industrial enterprises;
- switchgear of power plants' own needs;
- public utility facilities;
- and other power supply facilities.
AIS KSO-243 "Omega" cells are installed both in permanent closed switchgear buildings and in special quickly-assembled modules of full factory readiness.
Features of KSO-243 "Omega" cells;
The frame of the KSO-243 "Omega" cameras is made of steel with an aluminum-zinc coating, the facade doors are powder-painted, which makes the structure reliable and durable. The compactness of the design is achieved due to the location of the switching devices transversely relative to the busbars. The KSO-423 Omega housing contains power vacuum circuit breakers on draw-out elements, SF6 load switches and disconnectors, current and voltage measuring transformers, auxiliary transformers on draw-out elements, as well as high-voltage capacitors for reactive power compensation. To increase localization ability and ensure operational safety, the module body is divided into isolated compartments: busbars, secondary circuits, switching devices and cable connections.
Busbar compartment:
The insulated busbar compartment significantly increases the reliability of the structure and eliminates the possibility of overlap inside the cell. Busbars are formed by serially connected busbar sectors made of electrical copper. The busbars are installed on the terminals of the fixed contacts of disconnectors or load switches. To localize the electric arc within one cell, in the busbar compartment there is the optional possibility of installing a panel with bushings for busbars. With a double-row arrangement of cells in the switchgear room, the sections are connected by a bus bridge or cable insert.
Secondary circuit compartment:
In the secondary circuits compartment, a microprocessor relay protection unit, devices for commercial or technical electricity metering, electrical measuring devices (ammeters, voltmeters), terminal rows, heating and lighting circuits, automation and operational interlocks are installed. The fluorine circuit bundles are laid in a cable duct built into the secondary circuit compartment of each cell. To inform maintenance personnel about the position of switching devices in KSO-243 "Omega" cells, a mnemonic diagram with light indication is used, which is placed on the compartment door.
Compartment of devices and cable connections;
All equipment of the compartment is technologically installed in a withdrawable design, including the power switch and current transformers. The voltage indication unit monitors the presence of voltage on connecting cable lines and busbars. It receives the signal from support insulators with capacitive voltage dividers. The design of the compartment doors has a reinforced structure and a mechanism that provides multi-point fixation of the doors to the cell body when they are closed.
