Air-insulated secondary switchgear up to 12 kV KSO-366

Air-insulated secondary switchgear up to 12 kV KSO-366 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-366 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-366 cells are installed both in permanent closed switchgear buildings and in special quickly-assembled modules of full factory readiness.
Features of KSO-366 cells;
- The camera body is manufactured in 2 versions:
- welded frame made of ferrous metal with polymer powder coating;
- the body is made of steel with an aluminum-zinc (zinc) coating, with weldless fasteners.
- The simplicity and safety of the design allow the cell to be serviced by personnel who do not have special skills in servicing such equipment
- AIS KSO-366 cells are equipped with mechanical interlocks that ensure the safety of the operating personnel:
- interlock that prevents the disconnectors from being turned off when the switch is on;
- blocking, but allowing the disconnector to be turned on when the grounding switch is switched on;
- blocking that prevents the grounding switch from being switched on when the disconnector is switched on;
- a lock that prevents the door from being opened when the grounding switch is disconnected.
- All operations with the switch are performed with the chamber door closed.
- The devices, instruments, current-carrying parts, insulating supports, fastenings, and supporting structures used in the KSO-366 chambers are selected and installed so that gases or oil emitted from the devices cannot cause harm to operating personnel and do not cause overlapping of the chamber insulation. AIS KSO-366 cell has observation windows on the front door to monitor the position of switching devices.
- A socket for an interior lighting lamp is installed inside each chamber, which makes it possible to safely replace burnt-out lamps without removing the voltage from the main and auxiliary circuits. Sockets for portable lamps and a switch for the interior lighting lamp are installed on the façade of the cells.
- AIS KSO-366 cells have the ability to dock with other types of cells using adapter panels.
