Operation conditions

The complete switchgears of K-01ES series are intended for indoor operation (climatic modification UHL3.1 in accordance with GOST 15150-69) under the following conditions:

• altitude above sea level 1000 m,
• ambient temperature from minus 10 up to plus 40°С,
• type of atmosphere - II in accordance with GOST 15150-69 (corresponds to industrial regions atmosphere).

Design and action

The complete switchgear panels of K-01ES series of all modification types represent a metal frame welded of the bent sections. Apparatus and devices according to the main and auxiliary circuit diagrams are installed inside.

K-01ES panel is divided into the following compartments:

The complete switchgears are delivered as separate metal cabinets with elements for joining them, at the request of the customer switchgears are delivered by transport blocks of up to three cases in the block with the connections of the main and auxiliary circuits mounted within the block.

The complete switchgears of K-01ES series are designed for front-side access.

For operation safety in the complete switchgears K-01ES there are:

Circuits of secondary switching of the complete switchgear panel are placed in the relay cabinet. The low-voltage equipment of auxiliary circuits is mounted inside the relay cabinet, or on the rear wall, or on the rotary panel. Secondary circuits diagrams are realized through a range of typical schemes using electromechanical relays, and also with the use of microprocessor relay protection devices of various manufacturers (of "Temp", "SEPAM", BMRZ, "Sirius" series and others). 

Diagrams are realized with direct, rectified and alternating operative current.
