Each of these PTs has a main body 1 in a cylindrical container 11.
2 and is filled with an insulating gas such as SF 6 gas as a section that is managed separately from the gas sealed in the entire gas insulated switchgear, and the high voltage side conductor 13 protrudes into the container 1. It is insulated and supported by a cone-shaped insulating spacer 14.

ランジ１６に取付けられている。 A secondary terminal (not shown) of the bus bar PT passes through the bottom plate 15 in an airtight manner and is led out into the cylinder 17, and the cylinder 17 forms a terminal box. Reference numeral 19 is a lid of the terminal box and is attached to the flange 16 so as to be removable from the outside.
なお、２０は変圧器接続ユニツト、２１は変圧

う。 In the above configuration, power is led to the cable and transformer connection unit 20 on the upper side via the cable mustard disconnector 2 on the lower side. At this time,
The voltage of each phase charging section is measured by bus bar PT10, and the measured value is led out into a cylindrical container 11 forming a terminal box and operates a predetermined meter via wiring. When inspecting or testing the bus bar PT10, the lid 19 is removed regardless of whether the container 1 or the bus bar PT10 is airtight.

の極めて実用的な効果を奏する。 As described above, according to the present invention, the busbars PT of each phase are arranged in a staggered manner so that the protrusions of the insulating spacers face each other on the parallel plane of the ceiling of the rectangular container, so the busbars PT can be stored in a narrow idle space, and the is more compact and has a sleeker appearance. The bus bar PT is attached to the rectangular container with a cylinder attached to the bottom plate, which also serves as a terminal box, so the attachment structure is simplified and the device can be downsized. Inspection and testing of the bus bar PT can be easily carried out by simply removing the lid of the terminal box without breaking the gas tightness of the square container or other parts. Since the bus bar PT is housed in gas, there is no need to finish painting the container and there is less deterioration over time compared to the conventional one placed in air, which provides extremely practical effects.
