Description of the Related Art In order to protect a power transmission insulator from a flashover accident caused by an abnormal voltage such as lightning, an insulator having an arc horn attached to a power receiving side metal fitting and a ground side metal fitting of an insulator series is well known. . These arc horns have a predetermined horn interval Z 0 according to the transmission voltage class.

It has only the function of preventing discharge along the insulator surface by causing arc discharge between the horn tips, and does not have the function of actively blocking the continuation flow due to flashover. Therefore, recently, a lightning arrester having a arrester function provided in parallel with a conventional arc horn has been put into practical use so as to more actively block the wake.

And a series gap Zz is formed between the arc horn 7 and the arc horn 7 attached to one end of the power supply side metal fitting 6. FIG.
Is an example of an insulator device for transmitting 33 kV power, the series gap Z z is 160 mm, and the horn interval Z 0 is 350 mm.

It has non-linear voltage-resistance characteristics, and has a low resistance when subjected to a high voltage such as a lightning surge voltage, and also has a low commercial voltage operating voltage compared to the lightning surge voltage. High resistance. On the other hand, the insulation strength between the insulator horn and the lightning horn is previously set lower than the insulation strength of the insulator horn. Therefore, when a high voltage such as a lightning surge voltage is received, discharge is performed between the series gap electrodes 3 and 7 so that the lightning arrester horn has a low resistance, allows the lightning surge current to pass, and causes the insulator ream 4 to pass through. After protection, and after passing the lightning surge current, a commercial frequency operating voltage lower than the lightning surge voltage is applied between the series gaps 3 and 7, but the lightning horn has a high resistance to this voltage and the commercial frequency And has a function of interrupting the subsequent flow in a short time.

ていた。Although the size of such a lightning horn 1 differs depending on the voltage class, the lightning horn 1 for 33 to 77 kV is relatively small and lightweight, so as shown in FIG. There is no particular problem even when used by mounting. However, since the lightning horn 1 incorporated in the insulator for 110-154 kV power transmission is large and heavy as shown in FIG. 4 (showing 110 kV), there have been many problems as follows.

く。First, the weight of the entire insulator is lost because the side of the insulator to which the lightning horn 1 is attached becomes heavier, and the entire insulator is tilted. As a result, the series gap length Z z is likely to vary between the series gap electrode 3 and the voltage application side of the series gap electrodes 7 of lightning protection horn 1. In addition, a large balance weight 8 is required to balance the weight, which leads to an increase in cost. Second, considerably large oblique overhang length X c in terms of the air gap length Z 3 secured for clamping voltage in series gap Z z, appearance of the entire device is deteriorated. Third, the polarity difference of the flashover voltage of the lightning impulse or the switching impulse is large, and the lightning arrester characteristics are not constant due to the positive or negative of the lightning current or the like. Fourth, the series gap electrode 7 attached to the power-receiving-side metal fitting 6 must be a ring horn due to corona characteristics, resulting in an increase in size and cost.

きる。Each of the lightning horns 14 and 16 has a bar-shaped series gap electrode 17 projecting from the tip of a ZnO element, and the outer periphery of the main body is completely covered with an insulating coating 18. In case of 132kV transmission, lightning horn 1
The lightning horns 4 and 16 are the same as the lightning horns attached only to the ground side of the insulator for 66 kV power transmission. Therefore, it is not necessary to specially manufacture the lightning horns 14 and 16 for 132 kV, and the cost can be reduced.

The fourth embodiment is the same as the first embodiment except that the lightning horns 4 and 16 are the same as the lightning horn attached only to the ground side of the insulator for transmitting 77 kV. When the present invention is applied to an insulator for transmitting 110 kV power, the power-supply-side bracket 12 must
Attach a lightning horn 16 for 6 kV power transmission, and attach
1 may be provided with a lightning horn 14 for 33 kV power transmission. As described above, according to the present invention, the same lightning arrestor horn that is attached only to the ground side of the insulator for transmitting 33 to 77 kV power is attached to the ground side and the power receiving side, respectively, so that the voltage class of 110 to 154 kV is supported. Therefore, there is no need to separately manufacture a lightning horn for 110 to 154 kV, and the cost can be reduced.

る。The lightning arrester according to the present invention having the above-described structure is provided with a lightning horn 1 when receiving a lightning surge voltage.
The ZnO element incorporated in each of the horns 4 and 16 serves as a conductor, discharges between the series gap electrodes 17 and 17 at the tips of both horns to protect the insulator 10, and when the voltage decreases, the ZnO element becomes a conductor.
The O element serves as an insulator to prevent the following flow of the commercial frequency from flowing. The above functions are the same as those of a conventional lightning arrester having a lightning horn. In addition, insulation coordination between the ring horn 20 and the bar-shaped arc horn 21 facing the ring horn can be made in accordance with the power transmission voltage class as in the related art.

もに、装置全体のコンパクト化を図ることができる。However, the lightning arrester according to the present invention is different from the prior art, in that the grounding-side fitting 11 and the power-supplying-side fitting 12 of the insulator for transmitting 110 to 154 kV are each provided with one end.
Lightning arresters 14 and 16 of the same size and lightness as the lightning horn attached to the ground side of the insulator string for transmitting power of .about.77 kV are mounted facing each other. Therefore, it is easy to balance the weight with the arc horn 21 or the ring horn 20 on the other end side of the metal fitting, and a large balance weight as in the case of FIG. 4 is not required. Also, the amount of overhang in the horizontal direction can be reduced. For this reason, the aesthetic appearance of the entire apparatus is improved, and the entire apparatus can be downsized.

耐電圧特性を向上させることができる。Since the lightning horns 14 and 16 each containing a ZnO element are attached to both the power-supplying-side metal fitting 11 and the grounding-side metal fitting 12, the difference in polarity between the lightning impulse and the switching impulse flashover voltage can be reduced by the discharge suppressing effect of the ZnO element. It is possible to reduce the size, and to improve insulation coordination in both polarities and switching surge withstand voltage characteristics.

ずることがない。Furthermore, as a result of the lightning horns 14 and 16 being separately mounted, the capacitive coupling between the horn body and the series gap is well-balanced, so that the electric field at the tip of the series gap on the power application side is reduced. ZnO built in the horn
The element also has a discharge suppressing effect, and the corona discharge characteristics are improved by the influence of both. As a result, the same large-sized ring horn 20 as that of the related art is required on the other end of the power-supply-side metal fitting 11 without the lightning horn 14, but the series gap electrode 17 at the tip of the lightning horn 14 can be used as a rod-shaped electrode. Does not occur.

Since the insulator is separately mounted on the power application side and the grounding side of the insulator, the weight balance is less likely to be lost, and the overall size and cost of the insulator for 110-154 kV power transmission are reduced. be able to. Further, it has many advantages such as eliminating the difference in polarity of the flashover voltage and contributing to the improvement of the corona discharge characteristics.
