Abstract
The invention relates to a novel layout structure of a gas insulation switch device. The structure comprises several complete strings. Each complete string comprises six main buses and three branches. A first main bus, a second main bus and a third main bus represent A, B and C phases respectively. A fourth main bus, a fifth main bus and a sixth main bus represent the A, B and C phases respectively. Each branch comprises three breakers and six isolation switches. The three breakers in each branch are vertically arranged relative to the main buses respectively. The three breakers are successively connected in series. Two ends of each breaker are connected in series with isolation switches. The isolation switches located on two ends of the three branches are correspondingly connected to the A, B and C phases of the six main buses respectively. The branch between one pair of two isolation switches which are adjacent and are connected in series on each branch is connected to outgoing lines or incoming lines. The branch between the other pair of the two isolation switches which are adjacent and are connected in series is correspondingly connected to the incoming lines or the outgoing lines. Under the condition that the number of the outgoing lines and the number the incoming lines are almost equal, a land occupation area can be effectively saved and economic benefits are increased.
