Described spacer is two semicircular ring.
Due to described electrical conductor being set between the cabinet in splicing, the structure that the bus connecting between cabinet and bus are connected with pole adopts plug-in type, after cabinet splicing, the installation of bus or dismounting are carried out from cabinet top, can separately bus be installed or be removed, and the cabinet of need not moving away, the installation of bus or remove more convenient; Owing to all adopting auxiliary sealing structure in two cabinet bus junctions, and install more for convenience, and improved insulating properties.
The beneficial effects of the utility model are:
(1). bus connecting device is owing to being plug in construction, and equipment can first carry out cabinet splicing, carry out bus installation again while installing, and spells cabinet and bus installation simply, conveniently.
(2). can the bus of separate unit cabinet be removed or be installed, the impact that is not subject to adjacent cabinet or other element is removed or installed to bus.
(3). bus is installed junction and is coordinated closely, and interface dielectric strength is high, and properties of product are reliable.
