Abstract
A support insulator for supporting a high-voltage conductor within the interior of a gas-filled grounded housing has a generally triangular configuration, with the central bus supported within the interior of the triangle and with the apices of the triangle engaging the inner diameter of the grounded enclosure. An inner hub extending from the legs of the triangle assists in the support of the central insulator. The combination of a gas-filled high-voltage transmission line with a plurality of support insulators extending along the length of the line is disclosed.
Claims14
An insulator support for a gas-insulated transmission line;
- said gas-insulated transmission line comprising an elongated central conductor suspended within and along the axis of an elongated gas-filled outer housing;
- said insulator support comprising a generally triangularly shaped molded insulation member having three legs in a common plane and joined together at three respective apices;
- each of said three legs being generally inwardly bowed toward the center of said triangular shape;
- said inwardly bowed legs being adapted to engage and support said central conductor of a gas-insulated transmission line;
- each of said three apices being adapted to engage the inner diameter of said outer housing of said gas-insulated transmission line;
- each of said three legs being identical to one another;
- each of said three legs having a constant cross-sectional configuration for substantially their full lengths.
The insulator of claim 2 wherein said three legs are joined together by a central circular hub which is integral with said legs.
A gas-insulated transmission line comprising, in combination:
- a central conductor;
- an outer grounded housing;
- and a plurality of spaced support insulators for supporting said central conductor within said outer grounded housing;
- each of said support insulators comprising a generally triangularly shaped molded insulation member having three legs in a common plane and joined together at three respective apices;
- each of said three legs being generally inwardly bowed toward the center of said triangular shape;
- said inwardly bowed legs being adapted to engage and support said central conductor of a gas-insulated transmission line;
- each of said three apices being adapted to engage the inner diameter of said housing of said gas-insulated transmission line;
- each of said three legs being identical to one another;
- each of said three legs having a constant cross-sectional configuration for substantially their full lengths.
