Description

本発明は、公道上および宅地内の電力ケーブル地下配線を経由して建物の屋側部分に立ち上がり、電力取引用メーターまでの配線部分の電力ケーブル保護ダクトに関するものである。 The present invention relates to a power cable protection duct of a wiring portion that rises to a building side portion via a power cable underground wiring on a public road and in a residential land and reaches a power trading meter.

従来、電線類の地中化において、架空の電線から家屋に至る低圧架空引込線の家屋との接続点から電力取引用メーターまでの配線を地下からの電力ケーブル配線に変更する場合、公道上および宅地内に地中埋設した配管に、建物の屋側部分に金属管を取り付けサドル等により支持し、この配管の中に電力ケーブルを挿入し、公道上の地中電力ケーブルと電力取引用メーターを接続していた。 Conventionally, in the case of undergrounding electric wires, when changing the wiring from the connection point of the low-voltage overhead lead-in line from the fictitious electric wire to the house to the power transaction meter to the electric power cable wiring from the underground, on public roads and residential land A metal pipe is attached to the building's roof side to support it with a saddle, etc., and a power cable is inserted into this pipe to connect the underground power cable on public roads and a meter for power trading. Was.

前記方法によると金属管と電力取引用メーターボックスは直接接続できないことから電力ケーブルがむき出しになっており、電力計量しない電気を容易に取り出せる構造であった。 According to the above method, since the metal tube and the meter box for electric power trading cannot be directly connected, the electric power cable is exposed, and the structure is such that electricity without measuring electric power can be easily taken out.

前記金属管と電力取引用メーターボックスまでの電力ケーブルの配線において、金属管上部に防水パテ等を施設しても雨水が侵入していた。 In the wiring of the power cable between the metal pipe and the meter box for electric power trading, rainwater invaded even if a waterproof putty or the like was installed on the upper part of the metal pipe.

建物屋側の立ち上がり部分に金属パイプを使用していたため、漏電による感電防止を目的としたアース工事が必要であり施工に多くの時間や費用を費やしていた。 Since a metal pipe was used for the rising part on the building side, grounding work was required to prevent electric shock due to electric leakage, and a lot of time and money were spent on the work.

特許第４６２５９６７号の直状ダクトと配線ダクト連結具とを組み合わせた配線ダクトは、第三者が配線ダクトを取り外せない機構および雨水侵入防止構造を有していない。The wiring duct, which is a combination of the straight duct and the wiring duct connector of Japanese Patent No. 4625967, does not have a mechanism that prevents a third party from removing the wiring duct and a rainwater intrusion prevention structure.

特許第３７０１２８４号の可撓性配線ダクトは、第三者が配線ダクトを取り外せない機構および雨水侵入防止構造を有していない。The flexible wiring duct of Japanese Patent No. 3701284 does not have a mechanism that prevents a third party from removing the wiring duct and a rainwater intrusion prevention structure.

特許第３５３２７０５号のエアコン用冷媒管の保護ダクトは、第三者が配線ダクトを取り外せない機構および雨水侵入防止構造を有していない。The protective duct for the air conditioner refrigerant pipe of Japanese Patent No. 3532705 does not have a mechanism that prevents a third party from removing the wiring duct and a rainwater intrusion prevention structure.

建物屋側への立ち上がり部分から電力取引用メーターボックスまでの電力ケーブル配線において、電力ケーブルが、一部むき出しになっており損傷しやすいことから、第三者による感電あるいは盗電の防止が必要であった。 In the power cable wiring from the rising part to the building building side to the meter box for power trading, the power cable is partially exposed and easily damaged, so it is necessary to prevent electric shock or theft by a third party. rice field.

建物屋側への立ち上がりの金属管上部に防水パテ等を施設しても、雨水が電力ケーブルの隙間から公道上の地下ボックスへ侵入し電気的な漏電や電力ケーブルの寿命影響など保安上の問題があった。 Even if a waterproof putty is installed on the upper part of the metal pipe that rises to the building side, rainwater will enter the underground box on the public road through the gap of the power cable, and there are safety problems such as electrical leakage and the life of the power cable. was there.

地中埋設電力ケーブルおよび電力ケーブル保護管の建物屋側部分から電力取引用メーターボックスまでの電力ケーブル保護管接続方法として、本発明は、地中埋設管と直線角型ダクトを接続する差し込み方式のカップリング、直線角型ダクト、直線角型ダクトと可撓性ダクトを接続する差し込み方式のカップリング、可撓性ダクト、可撓性ダクトと電力取引用メーターボックス嵌合部を接続する差し込み方式のカップリング、電力取引用メーターボックスの嵌合部で構成し、地中配管と直線角型ダクトを接続する差し込み方式のカップリング、直線角型ダクト、直線角型ダクトの建物屋側部へのねじ固定、直線角型ダクトと可撓性ダクトを接続する差し込み方式のカップリング、可撓性ダクト、可撓性ダクトと電力取引用メーターボックス嵌合部を接続する差し込み方式のカップリングを順に取り付け、その後電力ケーブルを挿入し、最後に電力取引用メーターボックス上蓋を取り付け嵌合部のねじ取り付けにより、建物屋側の立ち上がり部分から電力取引用メーターボックスまでの電力ケーブル保護ダクト全体がロックされることにより、第三者による感電あるいは盗電の防止がはかれ電力ケーブルのセキュリティーが向上する。 As a method of connecting the power cable protection pipe from the building side part of the underground buried power cable and the power cable protection pipe to the meter box for power trading, the present invention is a plug-in method for connecting the underground buried pipe and a straight square duct. Coupling, straight square duct, plug-in method connecting straight square duct and flexible duct, flexible duct, plug-in method connecting flexible duct and meter box fitting part for power trading It consists of a coupling and a fitting part of a meter box for power trading, and a plug-in type coupling that connects the underground pipe and a straight square duct, a straight square duct, and a screw to the side of the building of the straight square duct. Install the fixed, plug-in coupling that connects the straight square duct and the flexible duct, the flexible duct, and the plug-in coupling that connects the flexible duct and the meter box fitting for power trading. After that, insert the power cable, and finally attach the top lid of the power transaction meter box and attach the screw of the fitting part to lock the entire power cable protection duct from the rising part on the building side to the power transaction meter box. , Prevents electric shock or theft by a third party and improves the security of the power cable.

建物屋側への立ち上がりから電力取引用メーターボックスまでの電力ケーブルが、保護ダクトに収められるため、損傷の可能性が無くなり、損傷した電力ケーブルにより感電する危険性も無くなる。 Since the power cable from the stand-up to the building building side to the meter box for power trading is housed in the protective duct, there is no possibility of damage and there is no risk of electric shock due to the damaged power cable.

建物屋側への立ち上がりから電力取引用メーターボックスまでの電力ケーブルが、保護ダクトに収められるため、意図的に電力ケーブルに電線を接続することがなくなり、電気を無断で使用することが出来なくなる。 Since the power cable from the rise to the building side to the meter box for power trading is housed in the protective duct, it is not possible to intentionally connect the electric wire to the power cable, and electricity cannot be used without permission.

従来は建物屋側の立ち上がりに金属パイプを使用していたため、漏電による感電防止を目的としたアース工事が必要であったが、本発明による保護ダクトの材料を樹脂製としたため、アース工事は不要となり施工が容易となった。 Conventionally, since a metal pipe was used to stand up on the building side, grounding work was required for the purpose of preventing electric shock due to electric leakage, but since the material of the protective duct according to the present invention is made of resin, grounding work is unnecessary. It became easy to construct.

従来は建物屋側の立ち上がりの金属パイプを固定するサドルが必要で数か所突起部分があったが、直線角型ダクトの内部でねじを取り付けるため、突起部分も無くなり見た目もスッキリで家屋への取り付けも容易である。 In the past, a saddle was required to fix the rising metal pipe on the building side, and there were several protrusions, but since the screws are attached inside the straight square duct, the protrusions are eliminated and the appearance is refreshing to the house. Easy to install.
