ABSTRACT:
The sliding mechanism (50) of a drawout type switchgear has a first slide arm (5) which is slidably supported by the upper and lower support rails (3A, 3B) and a second slide arm (7) which is slidably supported by the first slide arm (5). The second slide arm (7) is interlocked with the first slide arm (5) by a lock plate (12) when the first slide arm (5) is sliding from a connected position to a final drawout position of the first slide arm (5). When the first slide arm (5) reaches the final drawout position of the first slide arm (5), the interlocked second slide arm (7) is released by rotation of the lock plate (12).
