KSO-292 cameras

Chambers of the KSO-292M assembly series (in further KSO) are intended for installation in distributing devices and work in installations of three-phase alternating current, with a frequency of 50 Hz, of 6 and 10 kV in systems with the neutral isolated or grounded via the dugogasyashchy reactor.

The KSO-292M cameras are manufactured according to a grid of schemes of electric connections of the main chains and according to schemes of auxiliary chains of electric connections on electromechanical relays and microprocessor devices of protection, management, automatic equipment and alarm system.

Design

The KSO cameras represent the metal design welded from bent steel profiles. In chambers the appartura of the main chains is placed. On a facade the equipment of chains of management of protection and alarm systems which is placed on a door are installed the drive of switches and disconnectors, and also. Access to a high-voltage compartment is provided during the opening of a door and a sjema metallicheskigo the screen with an observation port.

Combined tires are installed in the top part of the KSO cameras and located in the vertical and horizontal planes.

In order to avoid wrong operations at service and repair of RU on chambers electric and mechanical blocking are provided.

At a two-row arrangement of the KSO cameras in RU on cameras tire bridges are established. Tire bridges represent the metal construction collected from corners with an ustanvka on them of insulators, tires and shinoderzhatel. If necessary disconnectors are installed
