Japanese Patent Application Laid-open No. 61-2 as a conventional lightning arrester for power transmission lines of this type.
There is one shown in Japanese Patent No. 60506. In this type of lightning arrester for power transmission lines, the upper part of the suspension insulator chain is attached to the tip of the tower arm, and the power transmission line is supported by the lower part of the suspension insulator chain. The upper end of the lightning arrester was fixed to the free end of the mounting bracket fixed to the tower arm, and a series gap was formed between the discharge electrode at the lower end of the surge arrester and the discharge electrode on the transmission line side of the suspension insulator chain. [0003] As described above, in the conventional lightning arrester for power transmission lines, since the series connection conductor of the lightning arrester and the series gap is electrically provided in parallel with the suspension insulator chain, when a lightning surge overvoltage is applied to the power transmission line, , the series gap is discharged and the follow-on current is blocked by the surge arrester, preventing flashover of the suspended insulator chain.

[Problems to be Solved by the Invention] However, in conventional lightning arresters for power transmission lines, the grounding side of the lightning arrester is directly connected to the tower arm, which is brought to the ground potential by a mounting bracket, and the lightning arrester is Since the ground side and the mounting bracket are at the same ground potential, it was not possible to check the operation of the lightning arrester, display information in the event of a failure, and understand the protective effect of the lightning arrester. [0005] An object of the present invention is to provide a lightning arrester for a power transmission line that can accurately identify the lightning arrester operating state and failure state of the lightning arrester and facilitate understanding of the protection effect. [0006] Another object of the present invention is to detect a malfunctioning lightning arrester and protect the lightning arrester by using an operation detection device to detect the current flowing from the ground of the lightning arrester during a lightning strike. [Means for Solving the Problems] In order to achieve the above object, the present invention electrically insulates and supports and fixes the grounding side of the lightning arrester to a mounting bracket attached to a steel tower arm, and the grounding side of the lightning arrester is fixed. A current path is provided between the side and the mounting bracket, and a failure detection device is connected to this current path. [0008] Since the lightning arrester for power transmission lines according to the present invention has the above-described configuration, it is possible to detect current flowing from the grounding side of the lightning arrester to the mounting bracket using the failure detection device. Thereby, the failure detection device can be configured with an operation recorder, a failure indicator, etc., and can grasp the protection effect of the lightning arrester. [0009]

Further, the mounting bracket 8 is fixed to the tower arm 4 at the middle in the longitudinal direction. A weight balancer 34 is supported at its left end, and a lightning arrester 10 is supported at its right end. More specifically, the left end of the ground conductor 7 is fixed to the right end of the mounting bracket 8 while being electrically insulated by an insulator 9. The ground side of the lightning arrester 10 is attached to the right end of the ground side conductor 7. A discharge electrode 13a is attached to the high voltage side of the lightning arrester 10. Further, a discharge electrode 13b is attached to the power transmission line 3 side of the suspended insulator chain 32. A series gap 11 is formed by these discharge electrodes 13a and 13b. Further, a ground conductor 5 is established in the above-mentioned mounting bracket 8. This ground conductor 5
A motion detection device 6 is configured between the ground conductor 7 and the ground conductor 7 to electrically connect them in series.

At this time, the failure detection device 6 is activated to record the operation of the lightning arrester 10 and display the operation in the event of a failure. [0012] Next, a specific example of the failure detection device 6 and the entire configuration used in the present invention will be described. 2 and 3 show a plan view and a front view of a first embodiment of the specific configuration of the lightning arrester for power transmission lines of the present invention. The left ends of the ground conductor 7 having an inverted U-shaped cross section are arranged opposite to each other. A resistance piece 40 having an H-shaped cross section is arranged between the two to obtain a desired distance 1. This resistance piece 40 has at least one end electrically insulated by an insulator 9, and the ground conductor 7 and the mounting bracket 8 are mechanically coupled with bolts. The ground side of the lightning arrester 10 and the ground side conductor 7 are electrically and mechanically connected by a conductor 42. A ground conductor 5 is established in the mounting bracket 8. There are lead wires 3 on both sides between the ground conductor 5 and the ground conductor 7.

is formed. [0013] The fault display device 6A has a built-in ignition powder, and does not operate in response to a lightning surge, but operates only in response to a short-circuit current when the arrester element is short-circuited. It is set so that it will not operate if it is not present, and the result will be as shown in Fig. 4 after the operation. Therefore, a failure of the lightning arrester 10 can be determined by visually observing the destruction of the failure display device 6A. [0014] FIG. 5 shows the configuration of a failure display device 6A used in the first embodiment of the present invention shown in FIG. protection gap 62 when lightning surge current is applied.
is discharged and flows and bypasses the energized coil, and only when an AC fault current is applied, the ignition agent 63 acts due to the heat generated by the energized coil 61, and the explosive force causes the fault indicator 6A to explode as shown in FIG.

[0017] This fault indicator 6B passes lightning surges as in the case of the embodiment shown in FIG. 6B falls, and the failure of the lightning arrester 10 can be easily detected by visual inspection from the outside. Note that a normal lightning arrester for power transmission with a gap forms a series gap 11 on the power transmission line side, and the voltage is divided between the capacitance of the arrester element and the capacitance of the series gap 11, and the transmission voltage is 30 to 40% of the voltage is applied to the surge arrester 10, and it is conceivable that this divided voltage causes the surge arrester element to deteriorate.

[Table 1] Table showing the discrimination method (Table 1) [0032] FIG. 22 shows an embodiment of the lightning arrester 10 used in the present invention. Zinc oxide elements 64 having voltage-current characteristics are stacked in series by crimping a connecting plate 71 with a constant piece 66 using a spring 72, and conduct lightning surges during a lightning strike to remove electricity from the grid. Cut off follow-on current. Since lightning arresters for power transmission lines are installed on the towers of power transmission lines, they need to be particularly lightweight and have improved explosion-proof performance compared to those for power generation and substations. In order to satisfy these two conditions, the lightning arrester 10 has an insulating tube 65 coated with silicone rubber 67 to eliminate the need for porcelain, making it lightweight and resistant to heat shock. . [0033] However, if the zinc oxide elements 64 are simply stacked,
The zinc oxide element 64 cannot withstand the increase in internal pressure caused by the ground fault current that flows when the zinc oxide element 64 burns out due to an excessive surge. This becomes possible by enlarging the space inside the insulating cylinder 65. In the present invention, by forming the zinc oxide element 64 into a donut shape, the increase in internal pressure is reduced by utilizing the volume on the inner diameter side. Furthermore, in order to prevent the internal pressure from increasing when the outer creeping surface of the zinc oxide element flashes, a donut-shaped connection plate 68 with a portion cut out is arranged to prevent the insulating cylinder 10 and the outer surface of the zinc oxide element 64 from increasing. The pressure generated during this time is guided to the inner diameter side of the zinc oxide element 64, thereby reducing the pressure rise. Donut-shaped connection plate 6
A metallic connection plate 76 is provided on both sides of the 8 and connected to the zinc oxide element 64. The generated internal pressure ruptures the pressure relief plates 79 at both ends, releases the internal pressure to the outside through the release hole 80 of the metal fitting 77, and short-circuits both ends of the metal fitting 77 with an arc to perform a pressure relief operation. A groove 70 is provided in the metal fitting 77 to strengthen the adhesion to the insulating cylinder 65 and increase the strength of the container. As a result, a lightning arrester with excellent explosion resistance can be realized. In the container forming the lightning arrester 10, an O-ring 69 is provided between the metal fitting 77 and the insulating tube 65 to improve the airtightness of the insulating tube. A plug 75 is installed for airtight sealing when the lightning arrester is assembled. Furthermore, O-rings 73 and 74 are provided for airtight sealing of the plug portion. [0034]
