VANIAn OUTDOOR TRANSFORMER.
Specicaton of ILetters Patent. Patented Oct. 10, 1911.'
Application filed October 18, v195239. Serial No. 523,126.
To all whom it 'may concern: v
Be it known that I, KARL C. RANDALL, a citizen of the United States, and a resident of Edgewood Park, in the countyof Alle gheny and-State of Pennsylvania, have invented a new and useful Improvement in Outdoor Transformers, of whichy the following is a specification.
Myinvention relates to electric apparatus, and it has special reference to outdoor transformers and to similar devices that are disposed in inclosing casings. 4
The object of my invention is to provide a simple and inexpensive shield structure for electric apparatus of the class indicated above in order to facilitate the cooling of the apparatus ,and to protect the inclosing cas ing from the direct rays ofthe sun, whereby the transformer or other device may be particularly suitable for use in the open fair.
High-voltage transformers have usually been located in sub-stations or sheds of some kind in order to protect them from the weather and from the direct rays of the sun. The terminal structures of such apparatus' and the inclosed casings have, however, been so developed as to withstand the rain and snow without injury, and, according to my present invention, I provide a simple shield which is not intended to protect the transformer casing from the wet, but is only intended to prevent the direct rays of the sun from heating the part-s within. p
'Figure l of the accompanying drawings is a view, partially in section and partially in elevation, of a transformer equipped. with myinvention, and Fig. 2 is a plan view of a portion of the device shown in Fig. l.
Referring to the drawings, a transformer or other electrical device is disposed within a tank or casing l, having a plurality-of tubes 2, which are located outside of the tank and form a communication between its upper and lower interior portions in order that oil or some other insulating Huid contained in the tank may circulate through them.
My protective shield comprises a cylindrical shell'3, of sheet metal or other suit- 50.
able material, which surrounds the casing l and is attached to the tubes 2 by means of4 brackets 4. Above the casing 1 is an outer dome 5, having an opening 6 through which the transformer leads 7 project, andan in-v I' of the casing and by brackets 11 whichare fastened to the shell 3. v
rlfhe shell 3' is so proportioned that its lower edge is at a material .distance from the ground, or the base on which the tank rests, so that the outside air may circulate freely around the tubes 2. The domes 5 and 8 are so located as to cast a shadow on the casing and permit the Warm air which rises from .the tubes to readily escape through the opening 6. It will be observed that the shield thus serves to protect the cas-ing from the direct rays of the sun and also to assist in producing a circulation of air around the tubes.
I desire that variations which do not depart from thespirit ofmy invention shall be included within its scope. `f I claim as my invention:
l. In electric apparatus, thecombination with an inclosing tank, of a shield for intercepting the direct rays of the sun, comprising a tubular portion spaced from the sides and bottom ofthe tank and a'roof portion having Ventilating openings.
2. An outdoor transformer comprising an inclosing tank and a shield supported and spaced therefrom and comprising a tubular portion the lower end of which terminates .in a plane above the bottom of the tank and a roof portion having Ventilating openings.
8. An outdoor transformer comprising an inclosing tank or casing having external tubes for increasing the radiating surface, and a shield secured to the tubes for intercepting the direct raysl of the sun and for promoting a circulationof air around the tubes, said shield comprising a tubular portion that is open to the atmosphere at 'its bottom and a roof portion having ventilat-` ing openings. l
4. In electric apparatus, the combination with a containing tank or casing, of a shield for interoepting the direct rays of the sun which comprises a cylindrical shell secured to the tank and spaced therefrom, and a its dome or cap supported above the tank and provided v vlth an offset central portion to perlrnit a free circulation of air around the tan 5. The combination with a transformer tank and a shell surrounding the 'side Walls of the tank and spaced therefrom, of a main shield cap having a central opening, and a' supplemental cap located beneath the openmosso? ing in the main cap and spaced therefrom 10 and from the tank cover.
n testimony whereof, l have herento subscribed my naine this 6th day of Oct.,
Copies of this patent *may be obtained for ve cents eachfb'y addressing the Commissioner of Patents,
