Definitions

  • This invention relates to a support structure for an air blast circuit breaker, and more particularly relates to a novel support structure which permits the permanent sealing between a compressed air tank and a hollow insulator support which conducts compressed air to interrupter structures carried by the support stand.
  • the hollow insulator then conducts compressed air from the main tank to the interrupter units so that it must be suitably sealed to the main support tank. Thus, some type of seal is required at the connection between the tank and the tall, hollow insulator.
  • the principle of the present invention is to provide a novel stand structure wherein the hollow insulator is directly and rigidly secured to the tank with the tank then being pivotally supported with respect to the ground.
  • Two additional insulators which are also pivotally supported then extend upwardly to form a tripod arrangement with the elongated hollow insulator column.
  • a primary object of this invention is to provide a novel support stand for air blast circuit breakers.
  • FIGURE 1 shows a front plan view of a support stand formed in accordance with the invention.
  • FIGURE 2 shows a side plan view of the stand of FIGURE 1.
  • FIGURE 3 shows a top plan view of the stand of FIGURES l and 2.
  • a support structure for air blast circuit breakers which includes a main compressed air-containing tank 1 which has a tubular hollow insulator 2 extending therefrom and rigidly connected thereto with the interior of insulator 2 communicating with the interior of tank 1.
  • the stand then includes additional links which include insulators 3 and 4.
  • the bottom of tank 1 is then pivotally connected to a ground support member 5 through any suitable pivotal arrangement such as a ball and socket joint.
  • insulator links 3 and 4 are pivotally connected to ground support members 6 and 7 which may also be of the ball and socket joint type.
  • the top of insulator 2 then has a suitable upper support rigidly connected thereto which pivotally receives the upper ends of insulators 3 and 4 as by the ball and socket joints 8 and 9 respectively which are schematically illustrated in the figures.
  • Suitable interrupter structures would then be mounted atop the upper end of insulator 2, with their interiors communicating with the compressed air conducted by the interior of insulator 2.
  • links 3 and 4 may be shortened or extended in any desired manner so as to appropriately position the main insulator column 2, and the air blast interrupters mounted thereon.
