Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...to secure maximum ventilation, the series and shunt coils being wound separately. The armature is of the ironclad type with the steel laminations mounted on a cast-iron spider. The armature coils are made waterproof and oilproof by dipping in armalac and baking for 24 hours in a temperature of 100C. Within the armature core are space blocks having radial arms that act like the blades or the vanes of a centrifugal blower, thus increasing the ventilation. This company also puts on the market a line of steam turbine generator sets ranging from 3 kw. at 3000 r. p. m. to 75 kw. at 2000 r. p. m., the generators being wound for voltages from 100 to 250. One of these is illustrated in Fig. 04. Triumph Electric Company. Engine Types. Fig. 65 shows one of a line of Triumph engine type generators, ranging in size from 30 to 1000 kw. The magnet frame is made of close grained cast steel with pole pieces of the laminated type bolted to the frame. Sizes smaller than 250 kw. have the frame split vertically, while the larger sizes have the frame split horizontally. The shunt and series coils are wound separately, the series coil being formed of solid bar copper, with spaces left between the coils. The armature is of the self-contained ironclad type. With the exception of the higher voltage and the smaller machines the armatures are bar wound, each coil consisting of one continuous length of solid copper, and held in position by hardwood wedges. Generating Sets. This company also builds a line of generating 6ets of the marine type as shown in Fig. 66, in sizes from 4 to 25 kw., all 4-pole machines and running at 500 to 350 r. p. m. Belted Types. Triumph belted generators are built in sizes ranging from J to 100 kw. The frame is made of close grained steel. The...show more
