Abstract:
A bus duct with variable volume comprises a conducting bar (1), an enclosure (2) and a variable-volume connector (3). The variable-volume connector (3) comprises: a fixed insulation plate (31) connected fixedly to the enclosure, and a movable conducting plate (32) fixed above the fixed insulation plate and being slidable relative to the conducting bar. The movable conducting plate (32) comprises stacked conducting sheets (35, 36). The conducting sheets are provided in the middle thereof with strip-shaped holes (35a, 36a, 40a) and they are connected by a bolt (37). A movable insulation plate (33) which is provided above the movable conducting plate (32) is connected fixedly to the movable conducting plate (32) and is movable with the movable conducting plate (32). The bus duct with variable volume has an extension function. Without changing the enclosure and the length of the conducting bar, the effective length of the bus duct can be increased or reduced, thereby being adaptable to various installation environments and effectively avoiding installation errors between bus ducts.
