この考案は、高圧配電線路等において、活線下で無停電工事を行なうために 、活きている電線路の絶縁体を針電極で突き破り、電気的に接続し、工事区域を 停電させないように、電力を供給するためのバイパス回路を作る際に使用される 多針電極式クランプに係るもので、詳しくは短絡電流等の大電流でも通電できる ように工夫した多針電極式クランプの構造に関するものである。 In order to perform uninterruptible work under a live line in a high-voltage power distribution line, etc., this device breaks through the insulator of the live line with a needle electrode and electrically connects them to prevent a power failure in the construction area. This relates to a multi-needle electrode clamp used when creating a bypass circuit for supplying electric power, and more specifically to the structure of a multi-needle electrode clamp devised so that it can carry large currents such as short circuit current. is there.

従来は、外見的には図1に示す構造の多針電極式クランプが使用されていた が、従来の中空円筒状の受け具1は図4に示すように、中空円筒状の受け具1の 内壁面と締め付けナット2の外壁面の間にはギャップ16があり、電流の通路は ねじ棒17から締め付けナット2の両端接触部を通じてバイパス回路に流れてい たので、電気抵抗が極めて大きく、キロアンペアにも及ぶ短絡電流等の大電を通 電できないという欠点があった。 Conventionally, a multi-needle electrode type clamp having a structure shown in FIG. 1 has been used in appearance, but the conventional hollow cylindrical receiver 1 has a hollow cylindrical receiver 1 as shown in FIG. Since there is a gap 16 between the inner wall surface and the outer wall surface of the tightening nut 2, and the current passage was flowing from the screw rod 17 to the bypass circuit through the contact parts on both ends of the tightening nut 2, the electric resistance was extremely large, and the kiloampere was used. It had the drawback that it could not carry a large current such as a short-circuit current.

The tightening nut 2 attached with is attached, the retaining ring 4 is attached next, the spring washer 5 is attached next, and the receiving nut 6 is finally screwed. In addition, 7 is a threaded portion screwed into the screw rod 17, 8 is a threaded portion engraved on the outer periphery of the receiving nut 6 and the inner surface of the receiving tool 1, 9 is a key fixing screw, 10 is a receiving tool fixing screw, and 11 is A flat washer, 12 is a spring washer, 13 is a terminal fixing bolt, 14 is a main body clamp, 15 is a horizontal pin, and 18 is a needle electrode.
【0007】 なお、現在実用化されているマルチバンドは、一ひだ当り電流容量が規定されて いるので、短絡電流等の大電流に対応できるようなひだ数のマルチバンドを、選 択して使用することが必要である。[0007] Since the multi-band currently in practical use has a specified current capacity per fold, a multi-band having a number of folds that can handle a large current such as a short-circuit current is selected and used. It is necessary to.
