Switchgear comprises a framework, a compartment of collecting buses, a compartment of current transformers, a relay compartment, a compartment of draw-out element with movable contacts, a ground connection, upper and lower stationary current conductive contacts. Polymeric bushing insulators are installed on a partition between the compartment of current transformers and the compartment of the draw-out element. To inside parts of the insulators, stationary current conductive contacts being connected with upper movable current conductive contacts of the draw-out element are connected. The draw-out element is performed as a low basis fixed relatively to the framework, an upper movable basis with a switch, and a rod. |
