【考案の詳細な説明】
この考案はコンデンサなどを搭載する絶縁架台

周知のように直列コンデンサ設備などは、線路
電圧が上昇すると、大地との絶縁を図るためコン
デンサ及び付属機器を絶縁架台上に搭載した構成
としている。 As is well known, in series capacitor equipment, etc., the capacitor and attached equipment are mounted on an insulating frame in order to insulate the equipment from the ground when the line voltage increases.
しかし、近年のように、線路電圧が275KV、
500KVといつたように超高圧化するにつれて、絶

る。 However, in recent years, the line voltage is 275KV,
As the voltage becomes ultra-high, such as 500KV, the corona resistance specifications of the insulating stand become stricter, and corona generation from edges that occur at the joint between the floor and the insulating support and at the outer periphery of the floor becomes a particular problem.
この対策として、たとえば前記結合部分のそれ
ぞれにシールドリングを設けて該部の電界緩和を

取付作業がきわめて煩雑となり好ましくない。 As a countermeasure to this problem, for example, it may be possible to provide a shield ring at each of the joint parts to alleviate the electric field at that part, but this would require a large number of shield rings, which would be uneconomical, and the installation work would be extremely laborious. This is complicated and undesirable.

特性の向上を図つたものである。 In view of the above-mentioned matters, this invention has a very simple structure by suspending a shield frame from the outer peripheral part of the floor so as to surround the joint part between the floor and the insulating support, thereby reducing the electric field of the joint part etc. This is intended to improve the corona resistance properties of this type of insulated stand.

電気機器である。 An embodiment of this invention will be described below based on FIGS. 1 to 4. Reference numeral 1 denotes an insulating stand, and a floor 4 is placed on a plurality of insulating supports 3 erected on a foundation 2.
It is constructed with insulated support. Said floor 4
and the insulating support 3, for example, the floor 4.
and a support element of the insulating support 3, for example a support insulator 31.
This is done by screwing the flange 32 of the Reference numeral 5 denotes a shield frame suspended from the outer peripheral part of the floor 4 so as to surround the joint part, and is made of, for example, a conductive pipe made of iron, aluminum, etc.
Shield frames 51, 52, 53 such as round bars are appropriately combined into a frame shape and fixed by welding or the like, and if necessary, by means such as screwing to the outer circumferential side of the floor 4 via a support 54 and a support plate 55. Fixed. 6
is an electrical device such as a capacitor mounted on the insulating frame 1.

で、コロナ発生電圧や消減電圧が上昇する。 According to the above configuration, the joint portion between the floor 4 and the insulating support 3 and the edges on the outer circumferential portion of the floor 4 are surrounded by the shield frame 5 having the same potential as the floor 4, and the electric field at the portion is relaxed. As a result, the corona generation voltage and extinction voltage increase.

る。 Next, another embodiment of this invention will be described based on FIGS. 5 and 6. Portions with the same reference numerals as in FIGS. 1 to 4 indicate the same or corresponding portions. In the illustrated embodiment, a part of the shield frame 5 is extended above the floor 4 and a protective fence 7 is provided. The protection fence 7 is formed by appropriately combining members 71 and 72 such as pipes and round bars into this shield material 51 in a fence shape and fixing them by welding or the like.

If so, it can also serve as a shield for the upper part of the floor 4, and the corona characteristics of the insulating frame 1 can be improved as in the above embodiment.

いつた種々の実用的効果を奏する。 As detailed above, according to this invention, by hanging the shield frame from the outer periphery of the floor, the electric field of the entire insulating frame can be relaxed, the corona characteristics can be improved, and the structure is simple. Therefore, compared to the case where a shield ring is provided at each joint portion between the floor and the insulating support base, various practical effects such as lower cost and improved workability can be achieved.
