Description of the invention (1) <Background of the invention> The present invention relates to the configuration of the gas-insulated switchgear, especially the configuration of the three-phase conductor of the gas-insulated switchgear in a grounded metal container. Conventional gas-insulated switchgear, as disclosed in JP-A No. 56-132107 and JP-A No. 5 5-1 3 9 0 10, arranges a three-phase conductor in a triangular shape in a cylindrical grounded metal container. Make up the bus. The former gas-insulated switchgear employs a configuration in which a three-phase conductor in a container that diverges at right angles from a grounded metal container is arranged in a triangular shape and is connected to a three-phase conductor in a bus bar. The latter gas-insulated switchgear employs a configuration in which the container-side conductor separated from the grounded metal container is connected to each of the three-phase conductors of the busbar. Also, traditional gas-insulated switchgear, such as Japanese Patent Publication No. 2-1 14813, printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Japanese Patent Office, please read the notes on the back before filling out this page) 5 _ 2 4 According to JP 7 7 10, each phase of a three-phase conductor arranged in a triangular shape is supported and fixed by an insulating support (Support), or as described in JP-A 6-30 — 0 1 The phase conductors are collectively supported by a disc-shaped insulating spacer (spacer) for fixing. However, in a conventional gas-insulated switchgear in which each of the three-phase conductors arranged in a three-angle shape is supported and fixed by an insulating support, the parallelism of each of the three-phase conductors is adjusted or adjacent to each other by adjusting the height of the insulating support. If the conductor is centered and adjusted, if there is a part such as a busbar branching, this assembly adjustment takes time. In addition, it needs to be used to support and fix the above-mentioned insulation support in the container. The paper size is applicable to the Chinese National Standard (CNS) M specification (210X297 mm). 2. The arrangement seat of invention description (2) makes the container structure complicated. In addition, since the three-phase conductors of the bus bar are arranged in a three-angled shape, when the bus bar is T-shaped, it is restricted by the direction of the pull-out, and can only be pulled out in one direction. In addition, the conventional gas-insulated switchgear which supports the fixed phase with a drawing board-like insulating spacer in a three-phase guide is generally used. Because the diameter of the insulating spacer and the container are the same, the strength of mechanical or stress such as gas pressure occurs. There may be problems such as the strength of electrical stress caused by material defects such as voids of epoxy itself. Also, in the conventional gas-insulated switchgear, there is a method described in JP-A-Sho 5 8-6 3 010 and JP-A-Sho 5-8-6 3 0 17 in which a three-phase conductor is placed vertically in a container. Gas-insulated switchgear arranged in a straight line in the direction; or as disclosed in JP-A-Sho 5 — 1 6 5 9 0 7; JP-A-Sho 6 0-9 3 1 4; JP-A-Sho 6 0-9 3 1 5 It is described that a three-phase conductor is collectively supported by an elliptical insulating spacer to support a fixed gas-insulated switchgear, but these do not take into account the above-mentioned problems at all. There is also a gas-insulated switchgear as described in Japanese Unexamined Publication No. 6 0-5 9 7 17 in which the three-phase conductors of the busbar and the three-phase conductors branching from the three-phase conductors are arranged in a straight line. Insulated switchgear is a straight line arrangement in which the branched 3-phase conductors are inclined to the direction of the 3-phase conductors of the bus bar, and the operating mechanism of the circuit breaker is used to return to the motion type. Therefore, the same rotary operating mechanism cannot be provided, and gas cannot be sought. Miniaturization of insulated switchgear.

As shown in the figure, the T branched bus bar portion of the gas-insulated switchgear is connected to one end side of the bus branch container 1 (also referred to as a grounded metal container) formed in a cylindrical, oval, or rectangular cross-section structure, and the T branch container 4 . A flange 21 is attached to the other end of the T branch container 4 with a fixing tool such as a bolt. An insulating spacer 8 is mounted at a substantially central portion of the flange 21 with a fixing tool such as a bolt. An end face flange 2 2 is attached to one end portion of the bus bar container 1 by a fixing tool such as a bolt, and an insulation spacer 12 is attached to a substantially center portion of the end face flange 22 by a fixing tool such as a bolt. On the other hand, the structure of the other end portion is the same as that of the one end portion, and the end face flange 23 and the insulating spacer 10 are attached to the one end side with fixing means such as bolts. In the sealed container thus formed, s F6 gas was sealed. In the busbar container 1, three-phase busbar conductors are arranged in parallel in a straight line in the longitudinal direction. One end of the insulating spacer 10 is fixed. The other end side is electrically connected to a conductor supported and held by an insulating spacer 12 through a horn-shaped contactor 11.

Here, the term “parallel parallel arrangement” refers to a configuration that is closer to a straight line than the previous triangular arrangement, including the case where the three-phase bus conductors 2 are disposed away from a straight line. In addition, the insulation spacers 10 and the insulation spacers 1 'supporting the fixed bus conductors can be applied to the same product. In addition, as shown in Fig. 4, the shape of the insulating spacers 8, 10 is set to an oval shape so that the insulation distances from the conductors of each phase to the ground are equal. In the T branch container 4, the 3 connecting wires branched from the 3-phase bus conductor 2 are arranged in a straight line, and a blade 3 belonging to a blade or a conductor is provided in the middle of each connecting line. In this embodiment, a three-phase branching conductor having three-phase busbars separated from the three-phase busbar conductors 2 and a three-phase vane 3 provided in the middle of the connection line is arranged perpendicular to the plane in which the three-phase busbar conductors 2 are arranged. The vertical central axis to this plane passes through the horizontal plane. The three-phase blade 3 has a rotating shaft-side conductor supported and fixed by the insulating spacer 8 on the insulating spacer 8 side, and a fixed-side conductor on the 2-phase bus conductor 2 side. The rotating side conductor is operated by the rotation of the rotating rod 7.

Description of the invention (&) In this example, as described above Forms a circuit breaker with a grounding device. Furthermore, a trumpet-shaped contactor 9 is placed outside the insulating spacer 8 so as to connect an unillustrated interrupter. According to this embodiment, since the three-phase bus conductors are arranged in parallel in the longitudinal direction in the busbar container 1 in a straight line, that is, the three-phase busbars are arranged in a straight line in the longitudinal direction on the central axis of the busbar container 1 or parallel to the central axis. Conductor, so the 3-phase bus conductor 2 can be divided in either direction. In other words, the three-phase bus conductor can be T-branched to make the left and right paired lines. In addition, if the T branch portion is constituted by a cross branch container, the three-phase bus conductor can be cross branched. In addition, according to this embodiment, since the three-phase bus conductors 2 are arranged in a straight line in the longitudinal direction in the busbar container 1 in a straight line, that is, the three-phase busbar conductors 2 are arranged in a straight line in parallel to align the central axis of the busbar container 1 with an axis. Symmetrically, a 3-phase branched conductor having a 3-phase connection branching from a 3-phase bus conductor 2 and a 3-phase blade provided in the middle of the connection line are arranged perpendicular to the plane in which the 3-phase bus conductor 2 is arranged and facing the plane. The vertical center axis is slightly horizontal in the plane, that is, the three-phase branch conductor is arranged so as to be axially symmetric to the center branch of the T branch container 4. Therefore, it is possible to share and standardize the components that constitute the gas-insulated switchgear, such as conductors, insulating spacers, blades, blade operating mechanisms, and containers. In this way, the cross of the three-phase bus conductor 2 can be divided, and the components constituting the gas-insulated switchgear can be shared and standardized. Therefore, the entire structure of the gas-insulated switchgear can be miniaturized, and the configuration of all the gas-insulated switchgear can be configured. Be applicable.

Description of the Invention (7) In this embodiment, as shown in FIG. 4, a 3-phase branch conductor is arranged in the T branch container 4. An example in which the center is deviated from some positions, and may be arranged on the central axis of the T branch container 4 in order to share and standardize the flange. In addition, according to this embodiment, since the three-phase bus conductor 2 and the branched conductor branching from the three-phase bus conductor 2 are supported by the insulating spacer installed on the flange, it is not necessary to provide the three-phase bus conductor 2 through the insulating support. And the branch conductors branched from the 3-phase bus conductor 2 support the required mounting fixed inside the bus container 1 and the T branch container 4 __, which can simplify the containers such as the bus container 1 and the T branch container 4. In addition, the three-phase bus conductors 2 and the branch conductors branching from the three-phase bus conductors 2 are arranged in parallel in a straight line using an elliptical insulation spacer, and the insulation to the ground of the bus container 1 and the T branch container 4 is equalized. Therefore, it is possible to miniaturize the volume and minimize the occurrence of material defects during resin injection molding. In addition, if the flange with the insulating spacer is machined, it can produce a precision dimension including the straight angle of the flange installed on the busbar container 1 and the τ branch container. Many of them are used as 3-phase busbar conductors during assembly. 2Each parallel adjustment and centering adjustment with adjacent conductors can simplify assembly work.
