本発明は送電鉄塔からの光信号を一箇所に伝送
集中させることによつて送電鉄塔の監視を行なう
送電鉄塔における落雷検知方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lightning strike detection method for a power transmission tower, which monitors the power transmission tower by concentrating the transmission of optical signals from the power transmission tower to one location.

電の可能性が生じることになる。 Transmission towers are prone to various failures,
The losses are often significant, especially when they are caused by lightning strikes, and lightning strikes can also induce reverse flashbacks, which can cause the power transmission system to stop functioning. , creating the possibility of widespread power outages.

発生する電位差によつて放電を生じさせ、これに
よつて火薬に点火し、その爆発力によつて標識を
出すことにより行なつていた。 Conventionally, lightning strikes are detected by using a detection coil to detect the current induced in a steel tower by a lightning strike.The electrical potential difference generated between the terminals of the coil causes an electrical discharge, which ignites the gunpowder, resulting in its explosive power. This was done by posting signs.

旧に要する時間も長いという不都合があつた。 However, with this detection method, it is only possible to detect lightning at the site of a lightning strike, and monitoring from a distance is not possible. Therefore, personnel must be stationed along the entire route of the power transmission line to monitor it periodically or when a lightning strike occurs. Therefore, there were disadvantages such as not only high maintenance costs but also a long time required for restoration.
このため、鉄塔に電源を動作する信号発生装置

対しては具体的解決策がないというのが現状であ
る。 For this reason, it has been proposed to install a signal generator on the tower to operate the power supply and transmit lightning signals to the monitoring station, but installing the power supply on the tower itself has its own problems, and the power supply is Since the signal generating device is affected by the induced magnetic field from the electric wire, there is a risk that the signal generating device will malfunction or break down, and the current situation is that there is no concrete solution to these problems.

点を解決するものである。 The first aspect of the present invention is to generate a time lag in the induced current induced in the steel tower by a lightning strike, and apply this to a light emitting element to generate an optical signal with an identification pattern unique to the steel tower. A second invention of the present invention is a method for detecting lightning strikes on each power transmission tower at a monitoring station by transmitting the information to the monitoring station.
By applying an induced current to a light emitting element that generates optical signals of different wavelengths, an optical signal with an identification pattern unique to each tower is generated, and this is transmitted to the monitoring station. This is a method of detecting lightning strikes on power transmission towers. This solves the above problem.

Since it is concentrated in one place, there is no need for a power supply for signal generation and processing, and there is no need to install a power supply on the tower. I have never had a problem.
