Description

  The present invention relates to an object type identification display device that is attached to a rod-shaped object that is classified into a plurality of types and is used to identify the type of the object by appearance.

  Electric wires such as high-voltage electric wires are classified into three electric wires having different phases, specifically, R-phase electric wires, S-phase electric wires, and T-phase electric wires. Moreover, since such an electric wire is almost the same color (black) in appearance, it is very difficult to identify each phase of the electric wire by appearance.

  For this reason, conventionally, for example, as shown in FIGS. 6 and 7, a phase grip 100 serving as a phase identification display of an electric wire is attached to the electric wire, and the phase grip 100 is colored, depending on the color of the phase grip 100. Each phase of the wire was identified. 6 and 7 are schematic views showing a phase grip according to the background art.

  Specifically, as shown in FIGS. 6 (a) and 6 (b), the conventional phase grip 100 is configured by a leaf spring portion 101 that is curved in a substantially circular shape. Some are discontinuous in the direction. That is, the vicinity of both end portions of the leaf spring portion 101 is opposed to a part in the circumferential direction, that is, a discontinuous portion.

  In addition, a narrow portion 102 having a width narrower than the base end side is provided at one end portion of the leaf spring portion 101, and a width wider than the width of the narrow portion 102 is provided at the other end portion of the leaf spring portion 101. The slit 103 is provided. The slit 103 extends to the other end portion of the leaf spring portion 101, and the other end portion of the leaf spring portion 101 has a shape in which a pair of branched claw portions 104 protrudes.

  Further, in the vicinity of both end portions of the leaf spring portion 101 constituting the phase grip 100, the distance between the narrow portion 102 and the base end portion 101a of the slit 103 is the smallest when the leaf spring portion 101 is not deformed. The narrower portion 102 and the distal end portion 101b of the slit 103 are larger in distance therebetween. That is, the phase grip 100 has a shape in which both end portions are bent away from each other at discontinuous portions.

  Then, as shown in FIGS. 7A and 7B, the phase grip 100 having such a shape engages the narrow portion 102 with the slit 103 so that the narrow portion 102 and the pair of claw portions 104 are engaged. Is attached to the electric wire 1 by sandwiching the electric wire 1 between the bent portions.

  Here, such mounting work of the phase grip 100 is generally performed by any one of a power failure operation, a direct hot wire operation, or an indirect hot wire operation. Along with the spread, economic loss has become large and has recently become unacceptable. The direct hot line work is not preferable because the work is performed without stopping the power supply to the electric power consumer, and there is a risk of an electric shock for the worker, that is, there is a risk of a work accident. The indirect hot line work is a work in a live line state like the direct hot line work, but the work is performed using a live line operation tool (for example, see Patent Document 1) that can be remotely operated. Accidents can be prevented.

  However, such an indirect hot line work is a work at a high place, and since the phase grip 100 is mounted on the electric wire 1 by remote operation using a live line operation tool, there is a risk of the phase grip 100 falling or the like. There is a problem that workability is very bad.

  The conventional phase grip 100 described above has a circularly curved portion of about 60 mm and has a relatively small outer shape, which adversely affects the work of attaching to the electric wire 1. That is, it is very difficult to mount the phase grip 100 having a relatively small outer shape on the electric wire 1 by deforming it with a live operation tool by remote control.

(Embodiment 1)
1A and 1B are a top view and a side view showing an outline of a phase identification display device for electric wires according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view schematically showing the electric wire phase identification display device according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the phase identification display device 10 for the electric wire 1 is attached to the electric wire 1, which is a high voltage wire having a diameter of about 23 mm and corresponding to about 6600 V, for example, and each phase (R phase, S Phase and T phase), and in this embodiment, the identification display unit 11 that enables each phase of the electric wire 1 to be identified by appearance, and the identification display unit 11 are joined to the electric wire 1 It is comprised with the winding part 12 wound.

  The identification display unit 11 of the phase identification display device 10 is a part that is attached to the electric wire 1 that is distinguished by three phases and that can identify the phase of the electric wire 1 by at least one of the shape and color of the appearance, In this embodiment, as shown in FIG. 2, a cylindrical identification display portion 11 a corresponding to the R phase, a triangular prism identification display portion 11 b corresponding to the S phase, and a quadrangular prism identification corresponding to the T phase. The display unit 11c is distinguished from each other. FIG. 1 shows a cylindrical identification display portion 11a corresponding to the R phase. In addition, each of the identification display portions 11a to 11c is formed with a through hole 13 penetrating in the longitudinal direction, and the overall shape is cylindrical.

Therefore, when the wire 14 is gripped by the live wire work tool 4 and wound around the electric wire, each protrusion 14 can be stretched by elastic deformation. In addition, since the shape of the state wound around the electric wire 1 is stored in advance, the winding portion 12 can be wound around the electric wire 1 relatively easily. That is, the efficiency of the mounting operation of the phase identification display device (identification display unit) can be improved.

  Moreover, by attaching each identification display part 11a-11c corresponding to each phase of the electric wire 1 in association with the corresponding electric wire 1, the phase of the electric wire 1 can be reliably identified in appearance.

  Furthermore, in this embodiment, since the winding part 12 (each protrusion part 14) was made into the spiral shape of 2 windings, the winding part 12 can be wound more firmly around the electric wire 1, and the phase identification display apparatus 10 from the electric wire 1 is obtained. Can be effectively prevented from falling.

  The present invention can be applied not only to the use for identifying the phase of the electric wire but also to the use as a marker for identifying the voltage value of the electric wire, for example.
