【考案の詳細な説明】
本考案は３心またはトリプレツクス型のゴム・
プラスチツク電力ケーブルの、部分放電測定用お
よび交流耐電圧試験用の終端に関するものであ
る。[Detailed explanation of the invention] This invention is a three-core or triplex type rubber
It concerns the termination of plastic power cables for partial discharge measurements and AC withstanding voltage tests.
上記の試験に純水終端容器を使用することは公
知である。しかし、従来は、３心またはトリプレ
ツクスケーブルの各線心ごとに純水終端容器を組
立てて、試験を実施していた。 The use of pure water termination vessels for the above tests is known. However, in the past, tests were conducted by assembling a pure water termination container for each core of a three-core or triplex cable.
したがつて、終端組立てに時間がかかり、かつ
試験の時に広い空間を占めるという問題があつ
た。 Therefore, there were problems in that it took a long time to assemble the terminals and occupied a large space during testing.
本考案は、上記の欠点を解消することを目的と
するもので、「第１、第２図」に示すように、１
個の純水終端容器１０内に３本のケーブルコア３
４をいつしよに入れて、同時に試験ができるよう
にしたものである。 The present invention aims to eliminate the above-mentioned drawbacks, and as shown in "Figures 1 and 2",
Three cable cores 3 in one pure water termination container 10
4 was included in the schedule so that the exams could be taken at the same time.
ただし、そのとき３本のケーブルコア３４が互
いにくつつきあうと、その部分に気泡が残り、そ
の中でコロナが発生し、それが部分放電測定時に
おけるエラーとなるので、本考案においては次に
述べるように、ケーブルコア３４が互いに接触し
ないような工夫をとつている。 However, if the three cable cores 34 touch each other at that time, air bubbles will remain in that area and corona will occur within them, which will cause an error during partial discharge measurement. As such, measures are taken to prevent the cable cores 34 from coming into contact with each other.
実施例（第１、第２図） これは３心ケーブルの場合である。Example (Figures 1 and 2) This is the case for a three-core cable.
１２は上部シールドリング、１４は下部金具で
それらの間に絶縁物からなる外筒１６と内筒１８
とが２重に設けてある。内筒１８には多数の孔２
０が開けてあり、入口２２から純水２４（106〜
107Ωcm）を内筒１８内に送り込むと、純水２４
はケーブルコア３４の回りを冷却しながら上昇
し、孔２０を通つて外筒１６内に移り、出口２６
から外に出る。そして、冷却装置およびポンプ
（両方とも図示省略）を通つて再び入口２２から
入り、循環する。 12 is an upper shield ring, 14 is a lower metal fitting, and between them an outer cylinder 16 and an inner cylinder 18 made of an insulating material.
There are two layers. The inner cylinder 18 has many holes 2.
0 is open, and pure water 24 (10 6 ~
10 7 Ωcm) into the inner cylinder 18, pure water 24
rises around the cable core 34 while cooling it, moves into the outer cylinder 16 through the hole 20, and exits at the outlet 26.
Go outside. Then, it passes through a cooling device and a pump (both not shown), enters the inlet 22 again, and circulates.
以上説明した所までは、公知の純水終端と同じ
である。 Everything up to the point explained above is the same as the known pure water termination.
３０はケーブルの全体を示し、３２はそのシー

３４が互いに接触しないように、それぞれの間を
適当に広げる。そしてこれらのケーブルコア３４

パツキン４０を設ける。これらのパツキ４０は、
両方とも、各ケーブルコアに接する部分４２およ

れらの部分で純水２４に対するシール作用をして
いる。またその他の部分４６は非弾力性を持つ材
料、たとえばエポキシ樹脂で作つてあつてその部
分がスペーサの役をしている。30 shows the entire cable, 32 its sheath, and 34 the cable core. The distance between each cable core 34 is appropriately widened so that the cable cores 34 do not come into contact with each other. and these cable cores 34
A packing 40 that also serves as a spacer is provided between the cable core 34 and the upper end of the outer cylinder 16 and between the cable core 34 and the lower metal fitting 14. These Patsuki 40 are
In both cases, only the portion 42 in contact with each cable core and the portion 44 in contact with the end container are made of a resilient material, such as silicone rubber, and these portions provide a seal against the pure water 24. The other portion 46 is made of a non-elastic material, such as epoxy resin, and serves as a spacer.
なお、各ケーブルコア３４のしやへい層３６と
下部金具１４とを電気的に接続し、また各ケーブ
ル導体３８と上部シールドリング１２とも電気的
に接続し、ケーブル導体３８に一括して高電圧を
印加して試験を実施する。 The insulation layer 36 of each cable core 34 and the lower metal fitting 14 are electrically connected, and each cable conductor 38 is also electrically connected to the upper shield ring 12, so that high voltage is applied to the cable conductor 38 all at once. Apply and conduct the test.
作用と効果
(1) 各ケーブルコアごとに別々に終端を組立てる
のでないから、終端組立ての時間および材料費
の大幅節約が可能になり、かつ試験時の占有空
間を小さくすることができる。Functions and Effects (1) Since the terminations are not assembled separately for each cable core, it is possible to significantly save time and material costs for assembling the terminations, and the space occupied during testing can be reduced.
(2) パツキン４０のうちの、弾力性を持つ部分
（ケーブルコアに接する部分４２と終端容器に

つてシールとスペーサとを別々に設けなくてよ
いから、構造が簡素化される。(2) The elastic part of the packing 40 (the part 42 in contact with the cable core and the part 44 in contact with the terminal container) serves as a seal, and at the same time, the non-elastic part 46 serves as a spacer. This prevents the cable cores 34 from coming into contact with each other. Therefore, it is not necessary to separately provide a seal and a spacer, which simplifies the structure.
