Description of the Related Art Conventionally, flashover indicators have been used to detect accidental currents flowing through a transmission tower by lightning and explode explosives to expose a display cloth stored in a case to the outside to detect a flashover accident. A display configuration is known.

た。However, since each steel tower is connected to the upper end of the steel tower by an overhead ground wire, the accident current is applied not only to the steel tower where the flashover accident occurred but also to the steel tower adjacent to the steel tower. Therefore, the flashing indicator installed in the adjacent steel tower is also destroyed, and this causes the display cloth to be exposed to the outside of the adjacent steel tower where no flashing accident has occurred, thereby identifying the steel tower where the flashing accident occurred. There was a problem that it was difficult.

ことが予想される。In order to solve this problem, a flash-on indicator is being developed which detects a change in the current of the overhead ground wire caused by a flash-over and identifies and displays the steel tower where the flash-over accident has occurred. However, since the flashlight indicator itself is large and this large flashlight indicator must be installed on the upper part of the tower, the installation work of the flashlight indicator is extremely troublesome and maintenance work is required. Is expected to be extremely troublesome.

しても誤動作を生じる可能性が高い。In addition to the above, there has been proposed a flashover indicator which detects a discharge flashing sound generated at the time of a flashover and an accident current flowing through a tower pedestal of a steel tower, and operates when these occur at the same time. Reliance on only the airborne discharge flash (discharging sound) makes it more susceptible to external noise, and malfunctions may occur even if a combination of the accident current flowing through the tower pier and the airborne discharge flash is detected.

防止される。FIG. 3 shows a second embodiment of the flashover display according to the present invention, which detects whether or not a flashover accident has occurred, based on the accident current and the discharge flashlight flowing through the tower leg 1a of the steel tower 1. In FIG. 3, 14 is a detection coil as a part of the fault current detection means. Detection coil 14
Is installed on the tower pier 1a and has a function of detecting a fault current A flowing through the tower pier 1a. When the fault current A flows, the detection coil 14 outputs a detection current based on a change in magnetic flux. The detected current is input to the rectifier 16 via the surge voltage absorption circuit 15. The surge voltage absorption circuit 15 has a function of suppressing a sudden increase in the detection current due to a sudden change in magnetic flux and protecting a circuit in the subsequent stage. The rectifier 16 rectifies the alternating current component of the detected current and converts it into a direct current output. The DC output of the rectifier 16 is a judgment circuit.
Entered in 12. Here, the judgment circuit 12 is arranged so that when the detection output of the flash detection means exceeds the reference value and the rectifier
Only when the DC output is input from 16, the determination result is output to the display means 13. Therefore, in this embodiment, the judgment circuit 12 and the display means 13 judge and display that a flashover has occurred in the tower 1 based on the detection output of the flash light detection means and the detection output of the accident current detection means. Functions as a means. According to this embodiment, even if artificial light such as sunlight reflection, scattered light, and search light enters the condenser lens mirror 7, the display means 13 does not perform flashing display unless an accident current is detected. As a result, malfunction of the flashlight display device can be reliably prevented.
