Plugging assembly and gas turbine with same

The invention discloses a plugging assembly and a gas turbine thereof, and relates to the technical field of gas turbines. The plugging head is used for plugging a first detector hole formed in the outer casing; a first plugging ball, a second plugging ball and a third plugging ball are sequentially formed on the plugging long rod from top to bottom; wherein the first plugging ball is used for plugging a third detector hole formed in the inner casing; the second plugging ball is used for plugging a fourth detector hole formed in the guide outer ring; and the third plugging ball is used for plugging a fifth probe hole formed in the guide outer ring. According to the guiding device, a second plugging ball and a third plugging ball are arranged on a plugging long rod, so that a fourth detector hole and a fifth detector hole formed in the guiding outer ring can be effectively plugged, and high-temperature fuel gas in a fuel gas cavity is prevented from entering a cooling cavity to erode parts in the guiding devic
