Description

  The present invention relates to an overhead wire bypass material mounting unit and a carriage for transporting the unit.

  When replacing a transformer installed on a utility pole, repairing an accident with an overhead line, or performing maintenance work on a transmission / distribution line, only the overhead line in the construction section or maintenance section can be used without stopping power transmission to the customer. Conventionally, an overhead line bypass method for stopping power transmission and transmitting power with a bypass cable during the suspension period has been used.

As this overhead wire bypass construction method, a direct hot wire operation in which an operator directly touches an electric wire and an indirect hot wire operation in which an operator performs an operation indirectly using a tool are conventionally performed (see Patent Document 1). ).
When installing equipment such as a construction switch directly on the power pole by direct hot-wire work, a large amount of armor is required for the current-carrying part, which increases the risk of electric shock, ground fault, and short circuit. In some cases, work is performed on the upper part of the utility pole by indirect hot wire work.

  In indirect hot-line work, work is performed using an insulating rod (hot stick) with various tools. Since an insulating rod (hot stick) is used, the operator does not work by touching the live part directly, so no protective clothing is required, and the risk of electric shock, ground fault and short circuit is low.

  In the conventional indirect hot line work, first, various equipment such as a construction switch and a bypass cable are separately transported to a work site by a transportation means such as a truck. Then, various equipment is placed on the bucket attached to the work vehicle, and the bucket is moved to the upper part of the utility pole. The worker on the bucket connects the construction switch and the bypass cable at the upper part of the utility pole, and fixes the construction switch at a desired position such as the upper part of the utility pole. After fixing the construction switch to the desired position, attach the bypass cable connected to the construction switch to the desired position of the wire using an insulation stick (hot stick), and within the section where the bypass cable is attached Then, an indirect hot wire operation is performed using an insulating rod (hot stick).

  As described above, in the conventional indirect hot line work, work for loading a construction switch having a weight of about 100 kg from a warehouse or the like onto a transportation means such as a truck, transportation from a transportation means such as a truck to a work site, work site It is necessary to carry out the work of loading in the bucket, attaching the bypass cable and other members to the construction switch, and installing the bucket from the bucket at the desired position such as the utility pole, etc. There was a problem of becoming.

  Patent Document 1 discloses a method of attaching or removing a construction switch (120) to or from an upper portion of a utility pole (P) via a high-pressure arm (121) (see FIG. 8). However, there is no technical idea that the high-voltage (bypass) cable (122) and other members are transported integrally with the construction switch (120) and attached to the utility pole (P) while being integrated. Several workers were required from transportation to installation, and the work was complicated.

JP2015-019482A
