本考案は、架空絶縁電線として用いると共に、その断線
事故を直ちに検知しうる光ファイバ入り絶縁電線に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical fiber-containing insulated wire that can be used as an overhead insulated wire and whose disconnection can be immediately detected.
架空配電に使用される絶縁電線は、第１図のように導体
１と絶縁体２の構成で雷や外力等により断線落下するこ
とがあり、前者の雷によるものは、半年間に延べ５００
件の発生が見られることがある。Insulated wires used for overhead power distribution have a structure of conductor 1 and insulator 2, as shown in Figure 1, and can break and fall due to lightning, external force, etc. In the case of the former lightning, a total of 500
Occasionally, the occurrence of cases may be observed.
通常配電システムは、異常発生時には送電が停止される
が、１分後には再送電されるのが我が国の標準である。In normal power distribution systems, power transmission is stopped when an abnormality occurs, but the Japanese standard is for power to be retransmitted one minute later.
このため、落下した絶縁電線には再び高電圧が印加され
ることになるが、絶縁被覆があるため殆んどの場合、そ
のまま電圧が印加されてしまい、地上には活きた高電圧
の電線が転がっている状態となり極めて危険である。For this reason, high voltage is applied again to the fallen insulated wire, but because of the insulation coating, in most cases the voltage is applied as is, and live high voltage wires are left lying on the ground. This is an extremely dangerous situation.
この場合配電線の断線落下を検知できれば、前述の再送
電を実施してよいかどうかの判断ができるようになり、
停電範囲を最小にし、かつ人身上の安全を確保できるこ
とになる。In this case, if it is possible to detect a break in the distribution line, it will be possible to determine whether or not to carry out the above-mentioned retransmission.
This will minimize the range of power outages and ensure personal safety.
本考案は、上記の事態に鑑みなされたもので、常時は架
空配電用絶縁電線として使用し、その断線事故を直ちに
キャッチし得ることを特徴とする光ファイバ入り絶縁電
線を提供するものである。The present invention was developed in view of the above-mentioned situation, and provides an insulated wire containing optical fiber, which is normally used as an insulated wire for overhead power distribution, and is characterized in that disconnection accidents can be detected immediately.
本考案の光ファイバ入り絶縁電線の実施例を第２図に示

のが適用できる。The shape of the protrusion into which the optical fiber 4 is embedded or inserted may have various cross sections A to E as shown in FIG. 3.
本考案の光ファイバ入り絶縁電線の使用方法を説明する
。A method of using the optical fiber-containing insulated wire of the present invention will be explained.
使用方法１
送電端に受光器を設け、電線が溶断する時のアーク光を
光ファイバでとらえて断線を検知する。How to use 1: Install a light receiver at the power transmission end and use an optical fiber to capture the arc light when the wire melts to detect wire breakage.
使用方法２
受電端に発光器、送電端に受光器を設け、常時光ファイ
バに光を通しておき、断線した時に光ファイバの光が途
切れることで、断線を検知する。Usage method 2: A light emitter is installed at the power receiving end and a light receiver is installed at the power transmitting end, and light is passed through the optical fiber at all times. When a break occurs, the light from the optical fiber is interrupted, and the break is detected.
使用方法３
送電端に発光器、受光器の両方を置き、受電端側は２本
の光ファイバを接続しておき、光ファイバを２本使い光
を往復させてその光が途切れることによって断線を検知
する。Usage method 3: Place both a light emitter and a receiver at the power transmitting end, connect two optical fibers to the power receiving end, and use the two optical fibers to send light back and forth, and prevent disconnection by interrupting the light. Detect.
使用方法４（応用）
受電端での開閉器等の操作、電力メータの読みの伝達等
の制御、情報伝達にも使用可能である。Usage Method 4 (Application) It can also be used for controlling switches, etc. at the power receiving end, transmitting power meter readings, etc., and transmitting information.
本考案の光ファイバ入り絶縁電線の効果は、（イ）断線
事故の殆んどである雷による溶断落下を使用方法１を用
いて検知できる。The effects of the optical fiber-containing insulated wire of the present invention are as follows: (a) Melting and falling caused by lightning, which is the cause of most wire breakage accidents, can be detected using method 1.
（ロ）使用方法２によって断線事故のすべてを検知でき
る。(b) Using Method 2, all disconnection accidents can be detected.
（ハ）光ファイバが複数本設けられているので、その中
の１本さえ残っておればよい。(c) Since a plurality of optical fibers are provided, only one of them needs to remain.
（ニ）使用する光の波長は単一である必要はなく、白色
光でもよい。(d) The wavelength of the light used does not need to be single; white light may be used.
また発光ダイオードと異なり容易に強い光源を得られる
