Description

  The present invention relates to a cutting aid for high-pressure underline. In particular, when cutting a high-voltage underline that is branched from an installed high-voltage distribution line and leads to a pole equipment such as a pole transformer through an insulator, both sides of the high-voltage underline are cut off. The present invention relates to a structure of a high-voltage underline cutting auxiliary tool that can be gripped by a pair of clips and that does not require a tool for indirect hot-line operation for gripping that prevents a high-pressure underline after cutting from hanging down and coming into contact with a pillar device. .

  There are two types of hot-line work that performs high-voltage distribution lines without power interruption: direct hot-wire method and indirect hot-wire method. In the direct hot wire construction method, workers wear protective equipment such as high-pressure rubber gloves and perform power distribution work by directly touching the high-voltage distribution line that is energized. On the other hand, the indirect hot wire method allows the operator to perform power distribution work without directly touching the high-voltage power distribution line that is energized using an insulating operation rod (hot stick) or the like.

  FIG. 9 is a perspective view showing a columnar state of the high-voltage underline. Referring to FIG. 9, a retaining clamp C covered with an insulating cover is disposed in the vicinity of the pin insulator Pi. The retention clamp C extends a high-voltage distribution line (hereinafter referred to as a high-voltage line) W and a high-voltage underline (hereinafter referred to as a pull-down line) We. In the tension clamp C, the underline We is branched and connected to the high-voltage line W. The underline We is anchored to a support insulator (not shown), and then the terminal is connected to a columnar electric device such as a transformer (not shown).

  Referring to FIG. 9, when the underline We is cut, both sides of the cut portion of the underline We are gripped by an insulating operation rod 9 for indirect live-line work described later (see FIG. 10). Thereby, the pull-down line We that gently descends and slopes from the high-voltage line W toward the columnar equipment hangs down after being cut and prevents contact with the utility pole P or the columnar equipment.

  FIG. 10 is a front view of an insulating operation rod for gripping a high-voltage underline or the like. Referring to FIG. 10, the insulating operation rod 9 is composed of a long operation rod 91 and a gripping tool 92. Further, the insulating operation rod 9 includes an operation rod 93. The gripping tool 92 is detachably attached to the distal end portion of the operation rod 91.

  Referring to FIG. 10, the gripping tool 92 is composed of a pair of curved gripping arms 9a and 9b that open and close. One gripping arm 9a is a fixed arm with a base end fixed, and the other gripping arm 9b rotates around a rotation shaft 9c provided at the base end of one gripping arm 9a. It is a movable arm.

  Referring to FIG. 10, the operation bar 93 is held along the operation bar 91. The distal end portion of the operating rod 93 is rotatably connected to the other gripping arm 9b. And if the operating lever 94 provided in the base end part of the action | operation stick | rod 93 is operated, the other holding arm 9b can be opened and closed with respect to one holding arm 9a. The insulating operation rod 9 is configured by an insulating plastic pipe or the like in the middle portion between the operation rod 91 and the operation rod 93, and ensures insulation so as to be suitable for the indirect hot wire method.

  The insulating operating rod 9 shown in FIG. 10 is a so-called “insulating Yoko” that can hold the underline We and the like placed at a high place with a pair of holding arms 9a and 9b (see FIG. 9). Further, the insulating operation rod 9 shown in FIG. 10 can also open and close the insulating cover covering the retention clamp C (see FIG. 9).

  However, referring to FIG. 9, when cutting the underline We, in addition to an insulating operation rod (not shown) having a cutting tool for cutting the underline We attached to the tip, the underline We A pair of insulating operation rods 9 that grip both sides of the cutting point are required. For this reason, in the conventional construction of cutting the underline We, the work efficiency that requires many workers is not excellent.

  In order to eliminate such problems, an insulating rod extending to a predetermined length, a clamp device that is disposed at one end of the insulating rod, and clamps the high-voltage distribution line from the outer peripheral direction with a fixed jaw and a movable jaw, and an insulating rod A high-voltage underline cutting aid that includes a clip member that is disposed at the other end and clamps the high-voltage underline from the outer peripheral direction is disclosed (for example, see Patent Document 1).
