Abstract
Official abstract text for this publication.
A hermetic portion on the side of a main body portion of a gas insulated switchgear and a hermetic portion of a bushing tank which has polymer bushings connected to the main body portion are configured separately, and electrical connection between the main body portion side and the bushing tank is carried out in an open portion. A mid tank is provided in the rear of the main body portion in which a switching apparatus is housed, and conductor portions which are horizontally led out from the main body portion are led into the mid tank, bent upward, and connected to bushings on the top of the mid tank. Cables are extended downward from the bottom of the bushing tank disposed above the mid tank via a support panel, and in the open portion, the cables are connected to the bushings.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gas insulated switchgear, comprising: a main body portion in which a switching apparatus is housed; and a mid tank which, being provided in a rear of the main body portion, conductor portions extended out from which are led into a container having sealed therein an insulating gas, has bushings to which end portions of the conductor portions are connected, wherein cables extended out from a connection target component portion are connected to the bushings, and the bushings and the cables are connected together in a support component portion which is an open space, wherein the connection target component portion is a bushing tank to which external electrical power is supplied, and the bushing tank is disposed above the mid tank, and wherein the bushings are disposed on a top side of the mid tank, and the cables extend linearly upward from the bushings. 2. The gas insulated switchgear according to claim 1 , wherein inside the mid tank, three of the conductor portions led out from the main body portion are connected one to each of three of the bushings provided in the mid tank. 3. The gas insulated switchgear according to claim 2 , wherein the conductor portions are led out in a horizontal direction from the rear portion of the main body portion, led into a side portion of the mid tank, bent in a height direction inside the mid tank, and connected to the bushings. 4. The gas insulated switchgear according to claim 3 , wherein the mid tank is provided integral with the main body portion. 5. The gas insulated switchgear according to claim 2 , wherein the mid tank is provided integral with the main body portion. 6. The gas insulated switchgear according to claim 1 , wherein the conductor portions are led out in a horizontal direction from the rear portion of the main body portion, led into a side portion of the mid tank, bent in a height direction inside the mid tank, and connected to the bushings. 7. The gas insulated switchgear according to claim 6 , wherein the mid tank is provided integral with the main body portion. 8. The gas insulated switchgear according to claim 1 , wherein the bushing tank has three polymer bushings protruding from a top portion of the container in which an insulating gas is sealed, and the three polymer bushings are disposed in a straight line on the top portion of the container. 9. The gas insulated switchgear according to claim 8 , wherein the mid tank is provided integral with the main body portion. 10. The gas insulated switchgear according to claim 1 , wherein the mid tank is provided integral with the main body portion.
