細心の注意を払わなければならない。又、重量も
大きく、運搬や取扱いにも不便である。 Gas insulated equipment has a structure in which a live part is supported by a support insulator made of a solid insulator, that is, an insulating spacer, in a container filled with a gas with excellent insulating properties such as SF 6 gas. The material for this spacer is generally a thermosetting resin such as epoxy resin, and it is manufactured by a casting method, but since it is a hard and brittle material, the mounting part must be precisely machined. is required and must be assembled with great care. Furthermore, it is heavy and inconvenient to transport and handle.
本考案は、このような点を改良し、絶縁スペー

ガスが封入されている。 1 is a container filled with SF 6 gas, and 2 is a conductor. 3 is an insulating spacer of the present invention. This insulating spacer has a floating ring shape formed by rotating a zigzag cross section around the conductor, and is sandwiched between the container 1 and the conductor 2. The insulating spacer 3 is made of an insulating material with rubber-like flexibility, and a hollow portion a therein is filled with a gas having excellent insulating performance, such as SF 6 gas.

から支持することができるようになる。 This insulating spacer 3 is easily installed between the container 1 and the conductor 2 because there is a slight gap or a very slight contact between the container 1 and the conductor 2 immediately before assembly, that is, under atmospheric pressure. The internal gas pressure is sealed to the extent that this is possible. In this way, after installing the insulating spacer 3 at a predetermined position, the gas pressure normally used for gas insulated equipment, for example 3~
Fill with insulating gas to about 4Kg/ cm3 . At this time, the insulating spacer 3 receives this gas pressure from the outside and contracts in the direction of the arrow, as shown in FIG. Then, the outermost b and the innermost c of the insulating spacer 3
are pushed outward and inward, respectively, pushing the conductor 2 into the container 1.
It will be possible to support from

組立作業上非常に有利となる。 As described above, the insulating spacer of the present invention can be easily installed in a predetermined position during assembly, and when the container is filled with insulating gas after assembly, it can firmly support the conductor. Done,
This is very advantageous for assembly work.
又、絶縁スペーサ自体も軽量であり、作業性が
良く、コスト的にも低価格のものが製作可能とな
る。 Further, the insulating spacer itself is lightweight, has good workability, and can be manufactured at a low cost.
絶縁スペーサ自体は、かなり柔軟性を持つてい
るので、容器や導体の仕上寸法はそれほど精度の
高いものでなくても、使用可能である。 Since the insulating spacer itself has considerable flexibility, it can be used even if the finished dimensions of the container and conductor are not very precise.
又、導体に働く輸送時や地震時などの衝撃力も
吸収されて、強度的にも有利である。 In addition, impact forces acting on the conductor during transportation or during earthquakes can be absorbed, making it advantageous in terms of strength.
このように、秀れた性質をもつ絶縁スペーサを
本発明により、安価に供給することが可能とな
る。 As described above, the present invention makes it possible to supply an insulating spacer with excellent properties at a low cost.
