MULTITERMINAL BREAKER CELL; METHOD OF CONSTRUCTING THE SWITCHGEAR SYSTEM OF A PRIMARY SUBSTATION CONTAINING AT LEAST ONE MULTITERMINAL BREAKER CELL; SWITCHGEAR SYSTEM OF A PRIMARY SUBSTATION

摘要

According to the present invention, a multiterminal breaker cell (1) and a switchgear system (51) of a primary substation with the breaker cells (1) are proposed. The cell design allows breakers to be installed in metallic boxes (2) with reduced overall dimensions. As a result, the possibility is provided to construct the switchgear system (51) that consists of several separate small-sized structural modules. In the proposed breaker cell, breakers (4a, 4b, 4c) are installed, with the corresponding insulated input terminals arranged along the longitudinal axes (A, B, C) of the corresponding breakers. The output terminals (30, 31) of each breaker are arranged along the straight line that is parallel to the longitudinal axis of the breaker. Each breaker contains elements (44) for fixing the breaker at a specified position relative to the input and output terminals of the substation.
