Description

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 556379 A7 — — B7 V. Description of the Invention (Technical Field to which the Invention belongs) The present invention relates to a three-phase integrated gas-insulated busbar used in a gas-insulated switchgear. (Conventional Technology) It is well known that most gas-insulated switchgear systems are used in power system switches. The main bus of a gas-insulated switchgear is a double bus system for stable power supply. The main bus is arranged in a phase-separated arrangement or a three-phase collective arrangement. The three-phase collective arrangement of the main bus is supported by a cylindrical bus container sealed with insulating gas by an insulating spacer, so that the three-phase main bus conductor is located at the apex of a triangle. Triangular systems usually form a bi equilateral triangle. In gas-insulated switchgear, the branch bus is pulled out from the three-phase collective bus. For example, it is described in Japanese Patent Application Laid-Open No. Sho 5 5 — 1 0 3 0 2 to pull out the branch bus from the three-phase collective bus. The branch bus that is pulled out from the three-phase collective bus must be pulled out in two directions from the machine configuration of the gas insulation switchgear. There are two directions for the pull-out, which are vertical and horizontal directions of the up or down direction. It is known that the branch bus is to be pulled out from the three-phase collective bus in two directions. From the viewpoint of miniaturizing the gas-insulated switchgear, the large / J, (cross-sectional area) of the bus container is limited, and the two bus containers are limited. Pull out in one direction and the other. This paper size applies to China National Standard (CNS) A4 (210X 297 mm) (Please read the precautions on the back before filling this page)

Description of the Invention (2) (Questions to be Solved by the Invention) The conventional technology uses two busbar containers to pull out in two directions. The main bus becomes longer, and two bus containers are required at the same time. The miniaturization of the gas-insulated switchgear is limited, and it cannot become a small and delicate shortcoming. The present invention has been made in view of the foregoing matters, and an object thereof is to provide a gas-insulated switchgear which can be pulled out from one busbar container in two directions to make the gas-insulated switchgear a compact and exquisite three-phase gas-insulated busbar. (Means for solving the problem) The present invention is characterized in that three vertical pull-out openings are formed along the longitudinal direction of the cylindrical bus bar container and three horizontal pull-out openings are formed at approximately the same axial position as the circumferential direction of the vertical pull-out opening, Configure the three-phase main bus conductor so that one side of the triangle at the apex of the three-phase main bus conductor becomes approximately parallel to the horizontal pull-out opening, and the main bus conductor is stretched to two verticals in sequence according to the main bus near the phase of the vertical pull-out. Pull out the exit position, and pull the branch bus from its front end position in the vertical pull out and horizontal pull out. In other words, the present invention relates to one of three vertical pull outlets (vertical pull outlets) formed along the length direction of the cylindrical busbar container with three-phase buses, two to two-phase buses, and three to three. There is a one-phase bus bar, which can pull out the branch bus bar at the front end of the main bus conductor of each phase. The present invention sequentially stretches main bus conductors from the main bus bar close to the phase of three vertical pull-out openings formed along the length direction of the cylindrical bus container to the three vertical pull-out outlet positions, and pulls them out from the front end position.
