are always required when several furnaces are to be supplied from one or more\nenergy supply systems. The simplest form of switching is furnace current\nswitching from one switching system to 2 following furnaces. An alternative\nhere would be effective current switching, with a condenser bank for each fur-\nnace. The furnace switching system with the optimum \u201creserve\u201d for the furnaces\nand the energy supply is the so-called busbar distributor. With this system, every\nfurnace can be switched to every power supply. This requires the same number\nof furnaces as energy supply systems, together with the corresponding number\nof effective current switches for each furnace. In the case of more than 3 furnaces,\nthese systems require too large and complex a busbar system, so that from 4 fur-\nnaces, a 2 x 2 furnace system is used.\n<\/p>\n\n\n\n
In mains frequency systems, the current to the furnace is approx. 4.5x higher\nthan the effective current. 250 Hz systems have a current to the furnace approx.\n7.5x higher than the effective current, while for 500 Hz systems, the current is\napprox. 11x higher than the effective current.\n<\/p>\n\n\n\n
As an alternative to these switching systems, other systems have been developed\nwith unstepped distribution of the output to 2 or more furnaces. These systems\nalso have the advantage that 2 furnaces can be supplied with energy simultane-\nously.\n<\/p>\n\n\n\n
Electronic switching has not come into such common use, since in this case only\n1 furnace can be supplied with energy at any one time. The switching off and on\ntime is approx. 1 second.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
