<p>PURPOSE:To miniaturize the whole device, by arranging breakers and disconnectors for forming a 1<1>/2 breaking system, in parallel with main bus lines, and by reversing the order of the breakers and disconnectors of adjacent bus line tie circuits, to connect line circuits to. CONSTITUTION:To a space between main bus lines 1, 2, equipment units A-C having disconnectors 4, 5, 7, 8, 10, 11 on both the sides of breakers 3, 6, 9 are connected to form bus line tie circuits. From the connecting points 18, 18 of the disconnectors 5, 7 and 8, 10, line circuits 12, 13 are branched to compose a 1<1>/2 breaking system. The equipment units A-C and the main bus lines 1, 2 are arranged in parallel with each other, and in the adjacent bus line tie circuits, equipment units A'-C' are reversely arranged. The main bus line side disconnectors 11, 11' of the two adjacent bus line tie circuits are connected to the main bus line 2 with a common connecting bus line 30, and at the end section of the bus line tie circuits, the main bus line disconnector 4 is connected to the voltage transformer 22 of the main bus line via a connecting bus line 31. As a result, an interval between the bus line tie circuits is shortened, and the whole device is miniaturized.</p> |
