<p>PURPOSE:To reduce the installation space by equalizing the width of a container at a section for containing a disconnecting switch and a compensation reactor connected with the primary neutral point of a ground insulation switchgear connected with a gas insulated device to the width of the gas insulated device and containing them in a same container. CONSTITUTION:An insulated transformer GT is arranged at the lower section of a container 10 where the primary of the transformer GT is connected in star and the neutral point thereof is connected through a connecting conduit 25 with the fixed contact 22 of a disconnecting switch DSo. A compensation reactor CRe is fixed above the container 10 and connected through a connecting conduit 24 with a movable contact 20 such that it moves between the fixed contact 22 for the disconnecting switch and the fixed contact 23 for the ground switchgear and closes the disconnecting switch DSo or a ground switchgear ESo. Secondary of the insulated transformer GT is connected in delta and connecting conduits 13u-13w are connected through insulation spacers 12u-12w arranged at the other side of the upper section of the container 10 with respective phase cable heads CHd. By such arrangement, the size of the gas container is reduced resulting in reduction of installation floor space.</p> |
