Abstract
Abstract A high voltage heavy current bus bar installation incorporates a tubular load-carrying conductor supported within a tubular outer enclosure to define an annular dielectric space which is filled with gas under high pressure. Gas is circulated at high pressure through the conductor and through an external heat exchanger independently of the means pressurizing the dielectric. A joint for adjacent sections of the installation provides for angular adjustment and includes mating connecting members sealed to the outer enclosures of the respective lengths and sealed to one another in a plane making an acute angle (preferably 45*) with the axis of each of the lengths. The conductors may be sealed together in a similar manner.

Total Claims: 12
Claim 1
Independent Claim
205 words
A high voltage heavy current bus bar installation incorporating at least one bus bar comprising a tubular outer enclosure and a tubular load-carrying conductor mounted coaxially within the outer enclosure and spaced therefrom by at least one insulatinG support to define an annular dielectric space, and means for maintaining in the dielectric space an insulating gas under high pressure, in which installation the tubular load-carrying conductor is filled with an insulating gas at high pressure and means are provided for circulating the said gas through the load-carrying conductor and through at least one heat exchanger external to the outer enclosure, said means being independent of means provided for maintaining the gas in the dielectric space under high pressure and including at least one joint between adjacent lengths of the installation which joint comprises two mating connecting members, one sealed to the outer enclosure of each of the adjacent lengths, each formed with a circular connecting rim lying in a plane making an acute angle with the axis of the tubular enclosure to which it is sealed, and means electrically connecting and sealing the conductors of the two lengths together within the chamber formed by sealing together the circular connecting rims of the two connecting members.
Claim 2
Dependent Claim
205 words
A high voltage heavy current bus bar installation incorporating at least one bus bar comprising a tubular outer enclosure and a tubular load-carrying conductor mounted coaxially within the outer enclosure and spaced therefrom by at least one insulatinG support to define an annular dielectric space, and means for maintaining in the dielectric space an insulating gas under high pressure, in which installation the tubular load-carrying conductor is filled with an insulating gas at high pressure and means are provided for circulating the said gas through the load-carrying conductor and through at least one heat exchanger external to the outer enclosure, said means being independent of means provided for maintaining the gas in the dielectric space under high pressure and including at least one joint between adjacent lengths of the installation which joint comprises two mating connecting members, one sealed to the outer enclosure of each of the adjacent lengths, each formed with a circular connecting rim lying in a plane making an acute angle with the axis of the tubular enclosure to which it is sealed, and means electrically connecting and sealing the conductors of the two lengths together within the chamber formed by sealing together the circular connecting rims of the two connecting members.
