【考案の詳細な説明】
本考案は電柱上の変圧器二次側または低圧配電線から引
込線に至る間の柱上配線構造に関するものである。[Detailed Description of the Invention] The present invention relates to a pole-mounted wiring structure between a transformer secondary side on a utility pole or a low-voltage distribution line to a drop-in line.
一般の低圧配線は、高圧架空配電線から柱上変圧器を経
て低圧幹線に至り、一般家庭あるいは工場等に至る引込
線は、この低圧幹線に接続することによって配電が行な
われている。General low-voltage wiring runs from a high-voltage overhead distribution line through a pole transformer to a low-voltage main line, and power distribution lines are connected to the low-voltage main line to lead to general households, factories, etc.
ところで、従来この低圧線から引込線へ至る間の配線は
、絶縁電線をパイプに入れて配線したり、ケーブルを電
柱に沿わせて支持バンド等により固定する等の方法がと
られている。By the way, conventional methods for wiring from the low-voltage line to the drop-in line include placing an insulated wire in a pipe, or running the cable along a utility pole and fixing it with a support band or the like.

圧需要家へ配線されている。FIG. 1 shows an example of a conventional pole installation that uses insulated wires to pull down from a transformer, where 21 is a utility pole, 22 is a pole-mounted transformer, and 23 is a low-voltage terminal of the pole-mounted transformer. Low voltage main line 24
is connected to the low voltage terminal 23 and pulled down along the utility pole 21,
It is fixed to the low-voltage pin insulator 26 of the lead-in arm 25, and its terminal end is connected to the lead-in line 28 by a branch connector 27, and is wired to a low-voltage consumer.
図中29は低圧引込線28を固定する支持具、30は保
護の為のヒユーズで通常低圧引込線の電圧和にのみ取り
付けられる。In the figure, 29 is a support for fixing the low-voltage service line 28, and 30 is a fuse for protection, which is usually attached only to the sum of the voltages of the low-voltage service line.
この装柱方法は低圧幹線24に絶縁電線を使用している

に至る縁回り配線が、電柱21及び引込用アーム25の
付近で輻輳し、装柱作業者の安全性の面でも改善が望ま
れていた。Since this pole installation method uses insulated wires for the low-voltage main line 24, a protective pipe 31 is required to protect the insulator, and the wiring procedure is fixed with a protective pipe mounting bracket 32. After running the electric wire, the upper end is connected to the low voltage terminal 23 of the pole-mounted transformer, and the lower end is connected to the low voltage drop-in line using the branch connector 27. It is difficult to perform complicated work in such a posture, and when the low voltage service line 28 is multi-stranded, the support 29 of the low voltage service line 28 is separated by the branch connector 27.
The wiring around the edge of the pole is congested near the utility pole 21 and the retracting arm 25, and improvements have been desired in terms of safety for pole installation workers.
また第2図(正面図)及び第3図(平面図)は従来の他
の装柱例で絶縁電線とは異り、ケーブルを使用するため
保護パイプを必要とせず直接電柱21に取り付けるよう
にしたものである。Also, Figure 2 (front view) and Figure 3 (plan view) are other examples of conventional pole mounting, and unlike insulated wires, cables are used, so there is no need for a protective pipe and the wires are directly attached to the utility pole 21. This is what I did.

の保守点検等において作業者が昇柱して安全帯を電柱に
巻く際、電柱とケーブルが密接しているため、安全帯を
ケーブルごと巻くことになりケーブルに損傷を与える事
故もあった。That is, this is a pole installation method in which several low-voltage main lines 33 are arranged in parallel on the utility pole 21 and directly fixed to the utility pole 21 and the lead-in arm 25 using the utility pole band 34 and the binding wire 35, and the workability is better than the above example. Although this is an improvement, when a worker climbs up a pole and wraps a safety belt around the pole during routine maintenance inspections, etc., because the pole and cable are in close contact, the safety belt must be wrapped around the cable, causing damage to the cable. There were also accidents that caused damage.
更に、低圧幹線33と電柱21または引込用アーム25
等相互が接触しているため分岐接続子27の絶縁処理を
強固にする必要がある。Furthermore, the low voltage main line 33 and the utility pole 21 or the lead-in arm 25
Since the branch connectors 27 are in contact with each other, it is necessary to strengthen the insulation treatment of the branch connectors 27.
通常、この処理は絶縁テープ巻きによって行なわれるが
、多条の分岐線を有する分岐接続部を柱上でテープ巻き
することは長時間を要するという欠点があった。Usually, this process is carried out by winding with an insulating tape, but there is a drawback that it takes a long time to wrap a branch connection having multiple branch lines on a pole with tape.
本考案は、これら従来の欠点を解消し、装柱作業を容易
とし、かつ保守点検時におけるケーブルの損傷のおそれ
の無い柱上配線構造を提供することを目的とするもので
ある。It is an object of the present invention to provide a pole-mounted wiring structure that eliminates these conventional drawbacks, facilitates pole installation work, and eliminates the risk of cable damage during maintenance and inspection.

It can be directly fixed with wire 9 or 18, and bus bar 1 has 3 wires for single-phase 3-wire system and 4 wires for 3-phase 4-wire system, depending on the distribution method of the low-voltage line.
Since the books are twisted together, they can be fixed together with the mounting bracket 4, making it easy to attach to the pole.Also, since the books can be fixed apart from the utility pole 5 with the mounting bracket 4, the safety belt for workers during maintenance and inspection etc. can be wrapped only around the utility pole 5 through the gap between the utility pole 5 and the busbar portion A, eliminating the risk of damage caused by the safety belt as in the conventional case.
