Description

  The present invention relates to a distribution line covering repair cover for repairing a stripped portion of an electric wire to which a short-circuit grounding device is attached when performing a power failure work on the distribution line.

  Conventionally, when performing power outage work on a distribution line, a short-circuit grounding device (short earth) is attached to the electric wire in order to prevent an electric shock accident due to erroneous charging. The short-circuit grounding device has its lower end grounded to the ground, and its upper end is latched so as to come into contact with the charged part from which the wire is stripped. Therefore, after the construction of the distribution line is completed, the short-circuit grounding device is removed from the electric wire and the ground, so that it is necessary to repair it by covering the charging portion from which the electric wire is stripped.

  Currently, a common cover is used for repairing a charged part from which a coating on a 22 kV electric wire has been removed. The shared cover has a configuration that can be used as an insulating cover for, for example, a “branch sleeve”, a “clamping connector”, a “jumper sleeve”, and a “charging portion in an electric wire”. Among them, for example, there is a branch sleeve cover as shown in Patent Document 1. That is, the branch sleeve cover is configured to cover a branch sleeve portion that connects the electric wire and a branch line branched from the electric wire.

  Specifically, the branch sleeve according to Patent Document 1 is made of a synthetic resin and is composed of a pair of halved cylinders that are divided along the longitudinal direction while leaving the upper edge, and is formed in a substantially laterally rectangular shape on the side. It has a horizontally long cavity. An insertion hole through which the main line is inserted is opened at one end in the longitudinal direction, and an insertion hole through which the main line and a branch line positioned therebelow are opened at the other end.

JP 2001-309541 A (page 2-4, FIG. 1)

  When the branch sleeve cover according to Patent Document 1 is shared as a distribution line covering repair cover that covers the charging portion of the electric wire, the distribution line covering repair cover is relatively large and heavy, and is difficult to handle. In addition, since the configuration that the distribution line covering repair cover does not deviate from the charged part is not adopted in the horizontally long cavity part, the distribution line covering repair cover moves along the electric wire by receiving wind pressure or vibration. Then, there is a problem that there is a risk that a short circuit accident may occur due to the charged part being exposed to the outside due to deviation from the charged part.

  Therefore, the present invention has been made to solve the above-mentioned problems, and is dedicated to the charging part of the electric wire, it can be miniaturized and is easy to use, and it can be used safely without being displaced from the charging part. Is intended to provide.

  In order to achieve such an object, the distribution line covering repair cover according to the present invention is a synthetic resin that covers the charging portion of the electric wire by dividing the lower edge along the longitudinal direction and allowing both divided edges to expand freely. A cylindrical cover body made of a metal and a pair of split edges of the cover body are provided so as to protrude downward, and an engaging projection is provided on one side and the engaging projection is engaged and disengaged on the other side. A pair of projecting pieces provided with engagement holes to be freely engaged, a grip piece provided at the tip of a hot stick provided on the cover body, and a charging part of the electric wire provided on the inner peripheral surface of the cover body And an anti-slip piece for preventing unnecessary movement along the electric wire by contacting the cut end surface of the coating layer of the electric wire.

  Since the distribution line covering repair cover according to the present invention can be dedicated as a cover for covering the charging portion from which the electric wire has been stripped, the overall size can be reduced and the usability is improved. In addition, the engagement protrusion is engaged with the engagement hole with the pair of protruding pieces sandwiched between the tips of the hot stick, and the cover body is covered with the charging portion of the wire by holding the gripping pieces with the tips of the hot stick. The hot stick can be used and the work can be done easily and quickly. Furthermore, even if the cover body tries to move along the electric wire due to wind pressure or vibration, the anti-slip piece comes into contact with the charging part and hits the cut end surface of the coating layer to prevent unnecessary movement. There is also an effect that the charging part is safely covered.

  Hereinafter, the best embodiment of the distribution line covering repair cover according to the present invention will be described in detail with reference to the drawings. 1 is a perspective view seen from one side of a distribution line covering repair cover according to the present invention, FIG. 2 is a perspective view seen from the other side, FIG. 3 is a perspective view showing an inner surface divided into two along the same longitudinal direction, 4 is an enlarged sectional view taken along line XX in FIG. The distribution line covering repair cover A has an inner diameter through which the electric wire W, which will be described later, is inserted and a length of about 240 mm, and the lower edge along the longitudinal direction is divided so that both divided edges 1a and 1a can be freely expanded. It consists of a cylindrical cover body 1 made of synthetic resin that can be opened. The cover main body 1 covers a charging part D where an electric wire W to be described later is exposed.

  The cover body 1 has an insertion hole 2 through which an electric wire W is inserted in an upper portion thereof, and a pair of protrusions 3 that overlap each other on the inner side surfaces of both divided end edges 1a and 1a in the cover body 1 respectively. , 3 are projected. These pair of protrusions 3 and 3 are provided corresponding to the charging part D of the electric wire W, and are for ensuring a creeping distance. Further, a pair of projecting pieces 4a and 4b are provided in a pair so as to project downward at both ends and the central portion along both split edges 1a and 1a of the cover body 1, respectively. And the engagement protrusion 5 which has the engagement nail | claw 5a at the front-end | tip protrudes substantially horizontally on the inner surface of each one protrusion piece 4a among these pair of protrusion pieces 4a and 4b. On the other hand, each other protruding piece 4b is provided with an engaging hole 6 in which the engaging protrusion 5 is detachably engaged.

  A surrounding frame 7 having a predetermined height is provided on the outer surface of each of the other protruding pieces 4b so as to surround the engaging hole 6. This is because, when the engagement claw 5a of each engagement projection 5 is engaged with each engagement hole 6, the tip of the engagement claw 5a is positioned in the enclosure frame 7 and does not protrude outwardly. The protrusions 4a and 4b in which the engagement protrusions 5 and the engagement holes 6 are engaged with each other using H are simply sandwiched from the outside so as to be easily performed. If the tip of the engaging protrusion 5, that is, the engaging claw 5 a protrudes outward from the surrounding frame 7, the outer surface of the protruding piece 4 a and the engaging protrusion 5 protruding from the protruding piece 4 a at the tip of the hot stick H are provided. This is because the end portion is sandwiched, and the engagement protrusion 5 cannot be engaged with the engagement hole 6 well.

  Further, in a state where the engagement protrusion 5 is engaged with the engagement hole 6, the opposed inner surfaces of the projecting pieces 4a and 4b are almost in close contact with each other, but the opposed inner surfaces 4c and 4c at the distal ends thereof are mutually distal. Inclined so that the distance between them increases. This is because, as will be described later, when the distribution line covering repair cover A is removed from the electric wire W, to disengage the engagement protrusions 5 from the engagement holes 6, for example, the tip of the driver R is placed on the protruding pieces 4 a, This is to facilitate insertion between 4b.

  A pair of gripping pieces 8 and 8 are provided at substantially central portions of both divided end edges 1a and 1a in the cover main body 1 at different positions in the longitudinal direction. These gripping pieces 8 and 8 are for gripping the cover body 1 with the tip of the hot stick H when the charging part D of the electric wire W is covered, so that the work can be easily performed. The attachment positions of the gripping pieces 8 and 8 are not limited to the two divided end edges 1a and 1a, and may be provided on the outer peripheral surface of the body portion of the cover main body 1, for example.

  At the substantially central portion of the inner peripheral surface 1b of the cover body 1, two pairs of misalignment prevention pieces 9, 9 located on both sides of the center line are provided along the longitudinal direction. The distance between the two sets of anti-slipping pieces 9, 9 in the longitudinal direction is narrower than the distance in the longitudinal direction of the charging part D exposed by peeling off the coating layer w of the wire W, and the cover body 1 is connected to the wire. When the W charging part D is covered, the inner peripheral edge of each misalignment prevention piece 9 comes into contact with the outer peripheral surface of the charging part D. Thereby, for example, even if the cover main body 1 tries to move unnecessarily along the electric wire W, any one of the anti-displacement preventing pieces 9 hits the cut end surface w1 of the coating layer w while slidingly contacting the outer peripheral surface of the charging part D, and the cover main body Prevent further movement of one. Thereby, the unnecessary movement of the cover main body 1 is prevented.

  The distribution line covering repair cover A according to the present invention has the above-described configuration, and the procedure for covering the electric wire W with the distribution line covering repair cover A will be described with reference to FIGS. As for the electric wire W, the coating layer w is peeled over the predetermined range, and the charging part D is exposed. In addition, a hot stick H is used to cover the electric wire W with the distribution line covering repair cover A. The hot stick H is constructed by attaching long operation rods h2 and h2 to the two handles of the insulating hat h1 for holding an object, respectively, and has insulation properties. For example, the electric work basket for an aerial work vehicle (It is not shown in the figure.) It is intended to make it possible to easily perform work at a high place by remote control from.

  First, as shown in FIG. 5, one grip piece 8 provided on the cover body 1 is sandwiched by the insulating edge h1 at the tip of the hot stick H with the divided edges 1a and 1a facing downward, and the cover body 1 Is arranged in parallel with the electric wire W at a position above the charging unit D. Then, the cover main body 1 is lowered as it is to approach the charging part D, and the cover main body 1 is covered with the charging part D while opening both the split end edges 1a and 1a. At this time, the two sets of misalignment prevention pieces 9 and 9 are in contact with the outer peripheral surface of the charging part D, and are positioned between both cut end faces w1 and w1 of the coating layer w.

  In this state, as shown in FIG. 6, a pair of projecting pieces 4a and 4b provided at three locations along the split edges 1a and 1a of the cover body 1 are sandwiched from the outside. Thereby, the engaging protrusion 5 is inserted into the engaging hole 6 and the engaging claw 5 a is engaged with the engaging hole 6. At this time, the protruding ridges 3, 3 protruding from the respective divided end edges 1a, 1a are arranged so as to overlap each other, and a sufficient creepage distance is secured. In this manner, the charging part D of the electric wire W is covered with the distribution line covering repair cover A as shown in FIG.

  In a state where the charging part D of the electric wire W is covered with the distribution line covering repair cover A, for example, when rainwater flows into the cover body 1, the rainwater flows down the upper surface of the ridge 3 and flows downward. At the same time, it is finally discharged downward from the gap between the two split edges 1a, 1a. Therefore, rainwater does not accumulate in the cover body 1 and there is no fear that the charging unit D will deteriorate.

  In order to remove the distribution line covering repair cover A, for example, the driver R is attached to the tip of the hot stick H, and the tip of both protruding pieces 4a and 4b that overlap each other as shown in FIG. The tip of the driver R is inserted between the opposing inner surfaces 4c, 4c of the part. As a result, the gap between the projecting pieces 4a and 4b is opened and the engagement claw 5a of the engagement protrusion 5 is detached from the engagement hole 6 so that the space between the divided end edges 1a and 1a can be expanded. In this state, the gripping piece 8 is gripped by the tip of the hot stick H as described above, and the distribution line covering repair cover A is pulled upward from the wire W. Thereby, the distribution line covering repair cover A can be removed from the electric wire W.

  As described above, the distribution line covering repair cover A according to the present invention can be dedicated as a cover for covering the charging portion D from which the covering layer w of the electric wire W has been peeled off. Become. Further, the engagement protrusion 5 is engaged with the engagement hole 6 with the pair of protruding pieces 4a and 4b sandwiched between the tips of the hot stick H, and the gripping piece 8 is sandwiched between the tips of the hot stick H to cover the cover. The main body 1 can be covered with the charging part D of the electric wire W, the hot stick H can be used, and the work can be performed easily and quickly. Furthermore, even if the cover body 1 tries to move along the electric wire W due to wind pressure or vibration, the anti-displacement piece 9 comes into contact with the charging part D and hits the cut end face w1 of the coating layer w, so that unnecessary movement is prevented. The cover body 1 is not displaced.
