本考案は、水冷ケーブル線路に使用する冷却水路用端末
装置の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a cooling waterway terminal device used in a water-cooled cable line.

。A water-cooled cable line in which a water-cooled passage is provided in the cable conductor For example, in a cable line in which a hollow conductor is used as the cable conductor and the hollow passage of this conductor is used as the water-cooled passage, the cooling water port at the end of the cable is at a high potential. As shown in FIG. 1, it is necessary to provide a porcelain pipe 3' between this cooling water port 1' and an external cooling water passage 2' at ground potential.
第１図において、４′はケーブル終端部の冷却水口１′
と碍管３′の高電位端とを連通ずる金属パイプである。In Figure 1, 4' is the cooling water port 1' at the end of the cable.
This is a metal pipe that communicates the high potential end of the insulator tube 3'.

流ｉを許容値におさえるように定められる。In FIG. 1, the current i flowing through the cooling water passage of the insulator tube 3'
is given by, where the inner diameter of the insulator tube is D, the length of the insulator tube is l, the specific electrical resistance of the cooling water is r, and the cable voltage is ■.The length l and the inner diameter D of the insulator tube are the leakage current i is determined to keep it within an acceptable value.

本の碍管を継ぎ合わせて使用せざるを得ない。Therefore, in high-voltage water-cooled cable lines, the length l of the above-mentioned insulator tube 3' has become significantly long (for example, the length is 3 to 4 m for a 275 kV class water-cooled cable), and it is necessary to use multiple insulator tubes. I have no choice but to use them in combination.

震等の外力に対し著しく不安定である。However, in the past, several insulator tubes were vertically connected in a straight line, and the shape was columnar, which combined with the fragility of the insulator tubes caused electromagnetic force due to short-circuit current in the event of a track accident, earthquakes, etc. It is extremely unstable against external forces.
