2 Claims.
vThis invention relates to an improved compressed neutralizing condenser having a corona shield, and is a division of my copending application Ser. No. 96,046, tiled Aug. 14, 1936, now Patent #2,193,500, patented March 12, 1940.
The invention covered by this'applicatlon relates to the terminal construction of a condenser particularly suited for neutralizing Purposes.
One object of my present invention is'to provide an improved terminal construction of a gas filled condenser whose capacitive value may be varied. A further object of my present invention is to provide an improved condenser which, though subjected to high voltages, is substantially free of or has a minimum of corona losses. A still further object of this invention is a means to protect the insulation .portion of the condenser structure from high voltage forming a metallic creepage path on the surface of the insulator. Other objects, advantages and features of my present invention will be self-apparent as the more detailed description thereof proceeds.
In the accompanying drawing, I havel illustrated a cross-sectional view of a neutralizingcondenser embodying the various features of my invention. v
Referring in detail to the drawing, I have shown a neutralizing condenser provided with an outer electrode or wall |28. The inner electrode structure |28 is adjustable and constructed as described in Hanseil' et al. Patent #2,192,062,
patented Feb. 27, 1940. lThe upper portion of' casing |28 is providedwith a cone-like insulator |38 of porcelain. Isolantite, Pyrex or any other suitable material having the necessary and requisite mechanical strength and insulating qualities. The lower end oi.' insulator |88 is provided with a flanged portion 2A over which a metallic ring 8 securely fastens the insulator to casing |28 by the cooperation of collars 4 and 4A and screws |42. To provide a gas-tight sealand also to prevent breakage of the insulator, a lead or rubber gasket l5 is employed between members |88, 4A and |28. Over the outside oi member 8, there is provided a hollow ring-like member |48 which acts as the lower portion of a corona shield to prevent an arc-over on the surface of the insulator, due to high voltage; within the central portion of insulator |88, a long hollow stem 8 is located,l the lower portionbeing secured to an inner Velectrode supporting member 8 which supports the iixed portion of the inner electrode 8. A shoulder portion l0 retains stem 8 against a gasket within the upper portion of insulator |88, the upper portion of stem 8 being threaded` with a iine thread I2 by means of which the adjustable lower portion i1 of the central electrode is raised or lowered within the aperture lA with the aid of and against the internal fluid pressure and actuated by means of a relatively long adjusting nut |80. The adjustable portion of the central electrode is retained in any desired position by means vof the internal fluid -pressure always acting upon and forcing the central adjustable electrode portion up against the lower portion of a rod I8. The
lthe condenser at its proper height on support member 52. The condenser is retained in a xed position by means of a second support member 58 and a threaded spacing member B4.
To prevent corona creepage along the surface oi' conical insulator |88, an annular shield or shell |40 which is made to be a snug iitat the base or insulator -cone |88, and is provided to shield and completely enclose the round head slotted screws '|42 for fastening cone |88 to base |28. As these screw heads frequently give rise to sparking .of an arc-over due to their sharp points caused by the use of screw drivers, etc.
during the assembly of the condenser terminal. a circular doughnut-shaped corona shield is provided at the upper end or apex of the insulating cone |88 which is in the form of a ring-shaped corona shield, and is supported by means of four metal arms |48. It has been found that by the provision of shields |44 and |48, the condenser may be subjected to voltagestwice as great as compared to the voltages at which. without shields, flashoveror arcing takes place between points |42 and |48.
While only one modification of this invention has been disclosed, it is to be distinctly understood that condenser terminal construction of this type are capable of other modifications and the invention should not be limited, except as to such limitations as are clearly imposed in the appended claims.
What is claimed is:
i. In high voltage terminal construction. in
combination. a casing member, an insulator having a shouldered base portion supported by said casig, il.` rina-liketerminal member on tre top of said insulator, a clamp ring, a plurality of binding' members for clamping the shouldered portion oi said insulator to said casing by said clamp ring, a metallic cover in the form oi an annular shield having substantially a semi-circular cross-section, said shield located above said clamp ring and arranged to loe a snug t on the outside wail of said insulator or completely enclosing sold binding members to prevent sparking or arc-over ce ced by sharp points thereon, and a hollow metallic ring forming a corona shield located above said cover and secured to an end opposite the shouldered portion ol said insulator im' reducing the tendency towards surface creepand ercover on said insulator.
2. voltage construction, combination, a cosing niemeer, en insulator havn or arc-over caused by sharp points thereon, and
a hollow metallic ring forming a corona shield located above said cover and secured to an end opposite the shouldered portion of said insulator for reducing the tendency towards surface creepage and arc-over on said insulator.
