(Cl. 10S-180) 2 claims. l
This invention relates to improvements in transformer tanks of the type adapted to enclose high voltage transformers which are cooled by the circulation of oil through the transformer which is enclosed in a suitable tank for that purpose.
The objects of the invention are to structurally form the tank in such a way that the shipping height and weight may be reduced.
This is accomplished by forming a well in the bottom of the tank and locating the truck wheels at the lsides of the well in the manner hereinafter more fully set forth and described in the accompanying specification and drawings.
In the drawings,
Figure 1 is a sectional elevation of a transformer in a tank constructed according to the present invention; and
Figure 2 is a sectional plan on the line 2-2 of Figure 1.
Referring to the drawings, A is a power transformer of any suitable design and B is a tank enclosing the same. In accordance with the present invention the bottom I of the tank is formed with a substantially central well II designed to receive the projecting core section I2 of the transformer. The formation of the well leaves a peripheral open space I3 around the bottom of the tank in which are located the truck wheels I6 suitably supported from supporting plates I'I connected to the tank. Conveniently four pairs of such truck wheels are provided, arranged as shown in Figure 2. The tank itself is conveniently of oval or elliptical shape as shown so as to conveniently fit the normal shape of a transformer of this kind, the lower core yoke of the transformer resting on the bottom of the usually rectangular well formed in the base of the tank. The well may extend the full length of the tank in which case the space I3 will extend along only each side of the tank and not around the ends. Generally in transformer tanks the transformer is mounted on an ordinary bottom plate and the wheels are mounted below the same. By the formation of the well in the manner indicated, a reduction of height as well as a reduction in weight is accomplished, due to the economy of material.
I claim:
l. In a transformer, the combination of a tank having a bottom wall, said bottom wall having a central depression therein providing a well and dening exterior recesses along opposite sides of the well, wheel trucks mounted in said recesses and extending slightly below said central depression, and a transformer core within said tank and having its lower end projecting into said well.
2. In a transformer, the combination set forth in claim 1, said wheel trucks comprising pairs of spaced bracket elements mounted in said recesses by attachment to said bottom wall, said elements having substantially the conguration of said recesses when viewed in side elevation, a pin supported by each pair of elements and bridging the space therebetween, a pair of spaced plates supported on each pin between each pair of bracket elements, and wheels mounted between each pair of plates.
