Description of the Related Art Conventionally, when performing maintenance, inspection or replacement of a distribution transformer 2 and a distributor (not shown) mounted on a pole 1 as shown in FIG. By using the electric wire temporary connection device 3 to which the connection metal fitting 7 is fixed at the tip, work without interruption is performed. That is, the electric wire temporary connection device 3 is connected to the bypass line 8.
Is temporarily fixed to a high-voltage pull-down line 10 wired from the high-voltage main line 9 to the transformer 2 from a high-voltage overhead line 9 in a state of being electrically connected. It is vertically fixed to a support fitting 13 attached to the support tool 12.

Subsequently, after the other end of the bypass line 8 is connected to a spare transformer (not shown), the connection fitting 7 is remotely operated by the operation section 11 at the rear end of the insulating support rod 4. By breaking the insulating coating of the high-voltage underline 10 with the tooth-shaped conductor clip of the connection fitting 7 and bringing the conductor into electrical contact with the conductor, the backup transformer is connected to the high-voltage overhead main line 9 and connected to a general household. Power supply becomes possible. Therefore, the high-voltage underline 10 is short-circuited by the bypass line 8, so that the maintenance or inspection is performed with the transformer 2 removed or as it is.

[0004] Further, the electric wire temporary connecting device 3 is connected to a support 1.
As shown in FIG. 6, the support member 13 for fixing to the fixing member 2 is a ring-shaped fixing portion 1 through which the support member 12 is inserted.
4, a fixing screw 17 screwed into the screw hole of the fixing portion 14, a fixed-side holder 18 integrally formed with the fixing portion 14, and a support pin 19 connected to the fixed-side holder 18. A movable holder 20 rotatably attached, a holding screw 21 held and screwed into a screw hole of the movable holder 20 and screwed into a screw hole of the fixed holder 18; It consists of.

[0005] The support fitting 13 fixes the wire temporary connecting device 3 to the support 12 in the following procedure. That is,
In a state where the fixing portion 14 is attached to the support member 12 in a state of being inserted, the movable side holder portion 12 is set in an open state indicated by a two-dot chain line, and the fixed side holder portion 18 is fixed to the predetermined position of the insulating support rod 4 in the temporary electric wire connecting device 3.

The tool 12 is inevitably supported vertically. In contrast, the pole transformer 2 is generally connected with a plurality of high-voltage lines 10, and requires as many high-voltage lines 10 as the temporary wire connection devices 3. In this case, the horizontal arrangement of the plurality of electric wire temporary connection devices 3 matches the arrangement of the high-voltage overhead main line 9, as is clear from FIG. Therefore, the length of the support 12 supported in a cantilever manner on the electric pole 1 becomes long, and the support of the plurality of electric wire temporary connection devices 3 becomes unstable. Must support a plurality of electric wire temporary connection devices 3, and the workability is further deteriorated.

Therefore, the present invention provides a supporting device for a high-voltage electric wire temporary connecting device which can support a plurality of electric wire temporary connecting devices in a short installation space in a horizontal direction and can fix the electric wire temporary connecting devices by one operation. It is intended to do so.

A mounting member having a C-shaped cross-section through which the support is inserted, and a pair of tightening pieces extending integrally from the mounting portion. The pair of fastening pieces are the support member. The mounting portion is configured to be deformed into a reduced diameter state by being pressed and bent in the proximity direction, and the support member is slidably and rotatable on the support shaft adjacent to the mounting member. A fixed-side holder provided, and a rotating-side holder connected to the fixed-side holder so as to be rotatable in a direction to come into contact with and separate from the support shaft; Are formed, each of which has a holding surface for sandwiching the same.

[0010] In the supporting device of the electric wire temporary connecting device, the mounting member is attached to the supporting member by inserting the supporting member through the mounting portion, and the movable side holder portion of the supporting member is rotated in a direction away from the support shaft. After that, the insulating support rod of the electric wire temporary connection device is located between both the fixed side and the movable side holder portions,
The movable holder is rotated so as to overlap the fixed holder, the insulating support bar is sandwiched between the holders, and finally the tightening member is tightened. By the tightening of the tightening member, both holder portions of the support member are acted on to be close to each other, and the support member securely fixes the insulating support rod, and at the same time, a pair of tightening pieces of the mounting member are pressed by the support member. The attachment portions are reduced in diameter by being bent in the directions approaching each other, and are firmly fixed to the support. Therefore, only by performing the tightening operation of the tightening member, the fixing of the support member to the insulated support rod of the wire temporary connecting device and the fixing to the support by the mounting member can be performed at the same time. improves.

In the temporary holding state in which the tightening member is not tightened, the support member can freely rotate about the support shaft with respect to the mounting member mounted on the support, so that the support member is rotated to rotate the electric wire. By inclining the temporary connection device, the attachment member can be moved to a position as close as possible to the utility pole side while sliding the attachment member against the support. This makes it possible to reduce the length of the support to approximately half the length of the conventional one, and to stably support a plurality of temporary wire connection devices within a short space in the horizontal direction.
