Ｊ Ｊ ｋ、２ Ａ ７号等に示されている。In general, there are two methods for alleviating the axial expansion and contraction of a conductor caused by heating and cooling: between the conductor and the insulating spacer, and between the container and the legs of the insulating spacer. There are two ways to alleviate the problem; in the former case, the space between the insulating spacer leg and the container is completely fixed, and in the latter case, the insulating spacer leg is fixed in the axial direction of the container. It is movable. Furthermore, it is already well known that high-voltage gas-insulated electrical equipment is provided with a particle trap device for trapping impurities such as metal powder mixed into the container; for example, this is described in US Pat.

不純物はリング状の粒子トラップ装置６で捕獲される。Figure 1 of the attached drawings shows a device in which the legs of the insulating spacer are movable and a ring-shaped particle trap device is attached in order to alleviate the thermal expansion and contraction that occurs in the axial direction of the conductor between the container and the insulating spacer. This shows an example in which a conductor in a container l is supported by a columnar insulating spacer 3, and a low voltage electrode provided at the tip of a leg 3a of the columnar insulating spacer 3 is connected to a rotating body 5 attached inside. Container l and columnar insulating spacer 3
It is movable between. Further, impurities mixed into the container 1 are captured by a ring-shaped particle trap device 6.

難になるという欠点があった。The conventional device is constructed in this way, but in order to move the legs of the leg-shaped or tripod-shaped columnar insulating spacer at appropriate positions in the container l, a hole is attached to the inner surface of the container l corresponding to one leg. Some kind of guide needs to be provided. however,
In this case, there is a drawback that it is difficult to provide the ring-shaped particle trap device 6 because it intersects with the guide provided in the axial direction.

る。In the figure, the container /, the conductor, and the insulating gas 7 are the same as those in the conventional device, but the symbol / is a tripod-shaped columnar insulating spacer that supports the conductor, and the tip of its leg /la is is provided with a low voltage electrode /2, and a rotatable metal rotating body 13 in contact with the container l is provided at its outer end. Further, on both sides of the low voltage electrode /2 on the inner surface of the container /, guide rails /lI are provided to guide the movement of the low voltage electrode 7.2, that is, the conductor of the leg l/a in the axial direction. , this guide rail blowfish is integrally provided with a particle trap device/S. A large number of grooves/ja are formed in this particle trap device is. Further, a Teflon ring 16 is provided at a position corresponding to the guide rail puffer of the low voltage electrode 12.
