<p>PURPOSE:To take out a circuit breaker without stopping main bus by arranging an L-type current path in a line side circuit breaker and coupling the line side circuit breaker with a connection bus through a bellows coupling and an L-type mounting/dismounting device. CONSTITUTION:A line side circuit breaker 5 is connected directly with a current transformer 2 which is connected with one lead-out part 1a of a circuit breaker 1 arranged vertically. An L-type current path is arranged in the line circuit breaker 5 and a mounting/dismounting device 21 is arranged in L-type thereon through a bellows coupling 20 so that the current path from the line side circuit breaker 5 is modified into horizontal direction and connected with a connection bus 7. The circuit breaker 1 can be drawn out by removing the upper cover of the mounting/dismounting device 21, contracting the bellows coupling 20 and removing the current transformer 2. By such arrangement, the circuit breaker can be taken out without interrupting the main bus and the installation space can be reduced.</p> |
