Busbars mounting systems

Figure 13.30 Possible arrangements for busbar mounting systems...

To obtain a strong busbar mounting system, suitable to withstand the electrodynamic forces arising out of a system fault, modern practice is to make use of thermosetting plastics, such as DMC (Dough Moulding Compounds)... 

The mechanical endurance of the current-carrying parts of all the equipment, bus system, deviees and components, used in a particular circuit as well as the load-bearing members and supports on which they are mounted. The electrical parts of a device (breakers and switches, etc.) are the responsibility of the component manufacturers. The manufacturer of the switchgear assembly is responsible for the busbar systems, metallic links and wires. 

Manufacturers may adopt different practices to mount the main and auxiliary busbars, depending upon the size, rating and fault level of the system. Some of the recommended and more common of these are illustrated in Figure I3.30(a)-(d) and discussed briefly below,... 

The purpose of a flexible joint is thus to make an electrical connection and to absorb the busbar s expansion and vibrations of the generator or the transformer and to prevent transmission of these vibrations to the bus system and mounting structure. 

Despite the advanced technology of the AQUATECH System, its installation is not complex. In fact, it is simpler and less costly than conventional electrolysis processing. AQUATECH Systems need only two electrodes for an entire 100-150 cell unit stack, avoiding complicated busbar arrangements. Furthermore, scale-up and installation of the unit are facilitated by the modular skid mounted cell stack design.
