(Conventional technology) Substations and power transmission and distribution lines are equipped with substations and power transmission and distribution lines that act as conductors for sudden voltages during lightning strikes, allowing them to escape to the ground side, and for normal voltages to escape to the ground. In some cases, lightning arresters are used that incorporate internal lightning protection elements that act as insulators. However, the internal elements of such lightning arresters deteriorate each time they are struck by lightning, so it is desirable to monitor the deterioration status.For lightning arresters at substations, a counter for the number of operations is incorporated inside and this can be visually checked. Some methods are used to determine the degree of deterioration by periodically disconnecting from the circuit and measuring the degree of deterioration. However, for lightning arresters on power transmission and distribution lines, which are distributed over a wide area, there is no special monitoring system other than those with a built-in means of indicating a failure in the event of a malfunction. It was impossible to monitor.

出することができる。(Embodiment) Next, the present invention will be explained in more detail with reference to the illustrated embodiment. In FIG.
is attached to the arm of the tower (11) and the power transmission and distribution line (3)
It is a lightning arrester that insulates and supports. For example, as shown in Figure 2, the lightning arrester (2) has an internal element (4) for lightning protection supported by a spring (5), and the lower seat part has a gap (not shown). (6) is a ground side flange, and (7) is an insulator).
6) is an insulated metal fitting, (9) is a ground electrode, and between the internal element (4) and the ground electrode (9) is an internal element (
4) A current sensor OI is attached to detect the current flowing. When detecting the degree of deterioration of a lightning arrester, current sensor a is a sensor that can detect minute currents of several mA or less, and when detecting the number of operations, current sensor α is a sensor with a peak value of 10 to 150 KA and a wave crest. This sensor can detect lightning current with a length of 1 to 10 μs. When detecting a failure, the current sensor Ql is a sensor capable of detecting a follow-on current of AC 10A to 50KA. In addition, the current sensor alI is a lightning current,
The current sensor Ql may be a single sensor that can also detect a follow-on current.In addition to a Faraday element, a search coil, a Hall element, etc. that directly detect the current flowing in the internal element (4), it can also detect a minute current as a voltage. Bockel elements, voltage dividing resistors, voltage dividing capacitors, etc. may be used.
In the embodiment, the output cable (11) from the current sensor Ql
is connected to the transmission box (12) mounted on the steel tower (11) through the center axis of the earth electrode (9), but the current sensor 01 does not necessarily have to be built into the lightning arrester (2), and is connected to the outside. May be installed in, but weatherproof,
From the viewpoint of noise resistance, impact resistance, etc., it is preferable to use a built-in type as in this example.
A converter (13) that converts the output of the current sensor α1 into an optical signal is installed inside the controller, and this optical signal is transmitted to the control center (15) through the overhead ground wire optical fiber cable (14). In this embodiment, in order to reduce the amount of information transmitted, for example, a plurality of lightning arresters (2) of the same steel tower (1) are grouped and only their representative values are transmitted. That is, the output of each current sensor Q of the plurality of lightning arresters (2) passes through an I/V converter (16) that converts the current into voltage, and then is digitized by an A/D converter (17).
A comparator (19) operated at regular intervals by a timer (18) extracts the maximum value within the group, and also a level setter (2) for multiple ranks of about 3 to 5 ranks.
0) into a frequency signal, which is converted to a frequency signal by a converter (13
) is converted into an optical signal. The converter (13) for detecting the number of operations is connected in parallel with the A/D converter (17) and has a built-in operation counter (25) that operates with lightning current or follow-on current. Note that when the current sensor (10) is a Faraday element or a Bockel element, the output cable (11) is an optical fiber, and in this case, it goes without saying that the l/V converter (16) should be an O/E converter. Also, if the timer (18) is not a self-emitting type and is of a type that emits an optical signal only when receiving a command from the control center (15), it may be omitted.
I can do it. On the other hand, in the control center (15) that receives optical signals from such a large number of lightning arresters (2), there is a photoelectric converter (21) that converts the optical signals into electrical signals, as shown in Fig. 1.
A computing unit (22), and input/output devices such as a CRT (23) and a printer (24) are provided. Then, as shown in the flowchart of Fig. 3, the computing unit (22) calculates each current value based on the transmitted current value of the lightning arrester (2) and the pre-stored Wei'pull distribution indicating the cumulative probability of failure occurrence. The degree of deterioration of the lightning arrester +2+ can be calculated by 6iJ. In addition, in insulators where deterioration is progressing, there is a phenomenon where the follow-on current value becomes thicker (or the flow time becomes longer), and this change is detected by the current sensor 01''?:'
If detected and judged by the arithmetic unit (22), an accurate degree of deterioration can be detected.

劣化検出の精度を向上させることができる。(Function) In the lightning arrester monitoring system of the present invention configured as described above, the current sensor θ attached to the lightning arrester (2) side of the power transmission and distribution line is connected to the internal element (4) of the lightning arrester (2).
A converter (13) detects the current flowing through the tower, converts it into an optical signal, and transmits it to the control center (15) through the overhead ground wire optical fiber cable (I4) stretched between the steel towers (11).Example When multiple lightning arresters (2) are grouped as in the case of grouping, only the maximum level current value in the group is converted into an optical signal and transmitted to the control center (15) at the timing determined by the timer (18). On the other hand, in the control center (15) that receives this, the optical signal is converted into an electrical signal by a photoelectric converter (21), and then
Based on the deterioration Weibull distribution curve stored in the arithmetic unit (22), the cumulative failure probability of the lightning arrester (2) that has sent the optical signal is determined, and the degree of deterioration is calculated from this. However, as shown in Figure 3, the deterioration Weibull distribution curve changes depending on the number of lightning strikes, so the accuracy of deterioration detection can be improved by inputting and correcting the number of lightning strikes for each lightning arrester (2). can be done.

If this occurs, the position of the lightning arrester (2) can be output to the CRT (23) or printer (24). Furthermore, power transmission stations where workers are waiting (
26) and send the data to CR of the terminal installed in the facility.
It can also be output to a T or printer. The work opening can be quickly maintained based on these displays, and measures can be taken to minimize damage by adjusting the load on the line.

業の発展に寄与するところは極めて大である。(Effects of the Invention) As is clear from the above description, the present invention allows the deterioration and operation status of lightning arresters on power transmission and distribution lines, which are distributed over a wide area, to be grasped in real time, so maintenance of the lightning arresters is easy. Not only is this easy, but it also makes it possible to take appropriate countermeasures in the event of a lightning strike. In addition, since an overhead ground wire optical fiber cable is used as a means of transmitting information between the tower and the control center, there is no risk of noise from lightning. If a method of transmitting signals is adopted, the amount of information carried on the optical fiber cable can be reduced, and the current sensor built into the lightning protection insulator is not affected by dirt on the surface of the insulator, so the detection accuracy can be reduced. As described above, the present invention eliminates the problems of the conventional technology of this type, and greatly contributes to the development of industry.
