Description

Dec. 30, 1958 I. K. FINNEY HIGH VOLTAGE INSULATION MOUNTING Filed June 6, 1955 INVENTOR 7 [mm KEN/v5 HIGH VGLTAGE INSULATION MOUNTING Ivan K. Finney, Uncasville, Conm, assignor to the United States of America as represented by the Secretary of the Navy Application June 6, 1955, Serial No. 513,617
1 Claim. (Cl. 174139) (Granted under Title 35, U. 8. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
This invention concerns high voltage insulation mountings and improvements therein.
Some types of high voltage insulators of the prior art are mounted in solid housings of ferrous metal. Where the insulation mountings are employed under conditions of high moisture or dampness they become rusty and require frequent maintenance and replacement. Under these conditions, a coat of moisture forms on the insulators and on the joints between the insulators and the insulation mounting to act as a current conductor short circuiting out the insulation to ground. The grounding of high voltage insulators is not only costly, due to high power loss, but may, under certain conditions, damage or destroy valuable equipment and be injurious or fatal to human life.
The principal object of this invention is the provision of an improved high voltage insulation mounting.
An object of this invention is the provision of a high voltage insulation mounting having a greatly reduced tendency to short circuit the insulator.
An object of this invention is the provision of a high voltage insulation mounting requiring little or no maintenance.
An object of this invention is the provision of a high voltage insulation mounting having greatly enhanced safety characteristics.
An object of this invention is the provision of a high voltage insulation mounting of simple configuration.
A further object of this invention is the provision of a high voltage insulation mounting of economical construction.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Fig. 1 is a full perspective schematic presentation of a preferred embodiment of the improved high voltage insulation mounting of the present invention; and
Fig. 2 is a full perspective schematic presentation of a high voltage terminal'utilizing the improved high voltage insulation mounting of the present invention.
The mounting 1 is preferably of cylindrical configuration; it is constructed of any suitable non-ferrous material known in the art, such, for example, as nickelcopper alloy. The windows 2, 3, 4 and 5 are cut in the mounting 1 in such positions that they do not adversely afiect the structural strength of said mounting.
The mounting 1 is of cylindrical configuration and is constructed of any suitable non-ferrous material known in the art. A preferred material for the mounting 1 is 2,6,845 Patented Dec. 30, 1958 any suitable nickel-copper alloy. The windows 2 and 4 are vertically aligned and in one portion of the mounting 1, whereas the windows 3 and 5 are vertically aligned and in the opposite portion of said mounting.
The top insulation plate 6 and the bottom insulation plate 7 are supported in perpendicular end relation to the mounting 1 by a series of support rods passing through holes in the corners of said plates. In the interests of clarity of presentation, only two of the support rods are shown in Fig. 2 and only one of the corner holes is shown. The end-threaded support rod 8 passes through a hole in a corner of each insulation plate. The support rod 8 positions the top plate 6 by the nuts 9 and it); said rod positions the bottom plate 7 by the nuts 11 and 12. The series of four support rods, of which the support rod 8 is one, serve to position the insulation plates 6 and 7 on the mounting 1 and to maintain sufiicient tension on said insulation plates that they remain in perpendicular end relation to said insulation mounting; said insulation mounting being, in effect, clamped between said insulation plates.
The insulator 13 is firmly affixed to the top insulation plate 6 in coaxial relation with the mounting 1. The insulator 13 supports the high voltage terminal 14, to which the high voltage line 15 is connected. The ground terminal 16 is supported by the mounting 1 and has the ground line 17 connected to it.
The windows 2, 3, 4 and 5 permit the free circulation of air through the mounting 1 and thus prevent the formation of short circuiting moisture between the insulator 13, the insulation plates 6 and '7 and said mounting 1. The non-ferrous construction of the mounting l. prevents its rusting and thus eliminates the need for frequent maintenance or replacement.
The high voltage insulation mounting of the present invention may be employed in all types of high voltage equipment and is not limited to the use as a terminal, shown.
Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claim the invention may be practiced otherwise than as specifically described.
I claim:
A high voltage insulation mounting which comprises a pair of insulating plates in face to face alignment but spaced apart, an elongated high voltage insulator extending from face to face through one of said plates well into the space between said plates, supported by said one plate and having a high voltage terminal at its exterior end for connection to a high voltage line, a cylindrical corona tube of non-ferrous metal surrounding that part of said insulator which is between said plates and at its ends abutting the inner faces of said plates, means for clamping said plates to the said tube with the tube approximately concentric with but spaced well from said insulator, and having open windows in its wall to ventilate the space around said insulator and prevent moisture condensation within the tube.
