いる。[Prior Art] FIG. 2 shows a cross section of a gas insulated current transformer described in Japanese Utility Model Publication No. 101443/1983. A primary coil 1 and a secondary coil 2 are housed in the tank 3, and the secondary coil 2 is provided so as to interlink with the primary coil 1. An insulating spacer 7 is provided at the top of the tank 3, and the primary coil 1 is fixed to this insulating spacer 7.
［発明が解決しようとする問題点］
従来の変流器においては、一次コイルは上部から支持さ
れているだけであり、このため一次コイルの機械的強度
が弱いという問題があった。すなわち、振動あるいは大
電流等によって一次コイルが動き、絶縁破壊が生じるお
それがあった。[Problems to be Solved by the Invention] In conventional current transformers, the primary coil is only supported from above, and therefore there is a problem in that the mechanical strength of the primary coil is weak. That is, there is a risk that the primary coil will move due to vibration or large current, resulting in dielectric breakdown.
この発明は上記の問題点を解決して、機械的に強固なガ
ス絶縁変流器を得ることを目的とする。The object of the present invention is to solve the above problems and obtain a mechanically strong gas insulated current transformer.
［問題点を解決するための手段１
この発明に係るガス絶縁変流器は、一次コイルを下方か
ら支持する絶縁部材を備えている。[Means for Solving the Problems 1] The gas insulated current transformer according to the present invention includes an insulating member that supports the primary coil from below.
［作用］
絶縁部材は、一次コイルを絶縁するとともに、機械的に
保持する作用を有する。[Function] The insulating member has the function of insulating the primary coil and mechanically holding it.
［実施例］
この発明の一実施例を第１図に示す。絶縁ガスが封入さ
れたタンク３の中には、一次コイル１、二次コイル２が
収納されており、二次コイル２は一次コイル１と鎖交す
るように設けられている。[Example] An example of the present invention is shown in FIG. A primary coil 1 and a secondary coil 2 are housed in a tank 3 filled with insulating gas, and the secondary coil 2 is provided so as to interlink with the primary coil 1.
タンク３の上部には、絶縁スペーサ１４が設けられてお

のフレーム１３によってタンク３内に保持されている。An insulating spacer 14 is provided at the top of the tank 3, and the primary coil 1 is fixed to this insulating spacer 14. Furthermore, an insulating boss spacer 11, which is an insulating member, is provided on a ground-side structure 12 below the primary coil 1, and the primary coil is supported from below. At this time, the insulating spacer 11 is set to have a sufficient length to prevent creeping damage between the live part and the ground part. The ground side structure 12 is held within the tank 3 by a belt-shaped frame 13.

なる。In this embodiment, since the frame 13 is provided, the contents of the current transformer, such as the primary coil and the secondary coil 2, can be assembled outside the tank 3. This simplifies work inside the tank 3 and facilitates assembly. Furthermore, by removing the frame 13, inspection and cleaning become easier.
なお、上記実施例では絶縁ボストスペーサ１１が２個の
場合について説明したが、１個もしくは２個以上設けて
もよい。In addition, although the case where the number of insulating boss spacers 11 is two was demonstrated in the said Example, you may provide one or two or more.

固に固定され、信頼性の高いガス絶縁変流器を得ること
ができる。[Effects of the Invention] The gas insulated current transformer according to the present invention not only supports the primary coil from above with the insulating spacer, but also supports it from the bottom with the insulating member. Therefore, the primary coil is firmly fixed, and a highly reliable gas-insulated current transformer can be obtained.
