を防止する。[Technical background of the invention and its problems] Figures 1 and 2 are explanatory diagrams of the prior art. 1 is the upright part of the tower of the overhead power transmission line, 2 is the arm of the tower,
3 is an insulator chain, 4 is a power transmission line conductor, 5 is a lightning arrester with or without a series gap, 6 is an insulating tube containing a conductor wire that is fused by a large current;
7 is a rotatable joint provided on the arm 2 of the steel tower. The lightning arrester 5 prevents flashover between the power transmission line conductor and the tower due to lightning striking the tower or the power transmission line conductor, and further prevents flashover between the power transmission line conductor and the tower due to switching surges occurring in the power transmission line conductor.

電が可能となる。すなわち再投入成功である。そ
うでない場合は再投入失敗である。 On the other hand, in power systems, a method is generally adopted in which a fault current caused by an insulation fault in a power transmission line is interrupted by a circuit breaker, and then the fault current is immediately restarted. If the insulation at the fault point has been restored between the shutoff and the restart, it is possible to continue transmitting power by restarting the power. In other words, the re-injection was successful. If not, reloading has failed.

故電流を遮断し、その後再投入したときは、アー
クによつて焼損した避雷器が切り離されているか
ら再投入が成功する。 In FIG. 1, if the internal elements of the lightning arrester 5 break down for some reason, a large fault current flows inside the lightning arrester 5 and the insulating tube 6. Then the insulation cylinder 6
The pressure inside increases, and the insulating cylinder 6 breaks down. Then, as shown in FIG. 2, the lightning arrester 5 rotates at the junction 7, and the power transmission line conductor 4 is separated. When the circuit breaker interrupts the fault current and then reinserts it, the reinsertion is successful because the lightning arrester that was burned out by the arc has been disconnected.
しかし、送電線導体４は風によつて大きくゆれ

ある。これを避けるためには、避雷器５と送電線
導体４との間を長くすれば良いが、鉄塔のアーム
２を長くしなければならず、経済的でない。 However, the power transmission line conductor 4 swings greatly due to the wind, and the power transmission line conductor 4 approaches the separated lightning arrester, causing a possibility of flashover and another accident. In order to avoid this, the distance between the lightning arrester 5 and the power transmission line conductor 4 can be made longer, but this requires making the arm 2 of the tower longer, which is not economical.

バすることのない、経済的な架空送電線路用避雷
装置を提供することを目的とする。[Purpose of the invention] An object of the invention is to provide an economical lightning arrester for an overhead power transmission line, which prevents a surge arrester that has been disconnected due to an accident from flashing over again even if the transmission line conductor is shaken significantly by wind. do.

The other terminal of the lightning arrester and the power transmission line conductor are connected using a disconnection device that is damaged by a large current.

点である。[Embodiment of the Invention] FIG. 3 shows an embodiment of the invention. 1 is the upright part of the tower of the overhead power transmission line, 2 is the arm of the tower,
3 is an insulator chain, 4 is a power transmission line conductor, 5 is a lightning arrester, 6 is an insulating tube containing a conductor that melts due to large current,
7 is a rotatable joint provided in the upright part 1 of the steel tower.

れる。 In FIG. 3, if an internal element of the arrester 5 breaks down for some reason, a large fault current flows inside the arrester 5 and the insulating tube 6. Then, the pressure inside the insulating cylinder 6 increases, and the insulating cylinder 6 breaks down. Then, as shown in FIG. 4, the arrester 5 rotates at the junction point 7 on the upright portion of the tower and is separated from the transmission line conductor 4.

き、風によつて送電線導体４が大きく揺れても、
フラツシオーバして再び事故となることがない。 When the circuit breaker cuts off the fault current and then turns on again, the reinsertion is successful because the lightning arrester burnt out by the arc has been disconnected. Since the junction point 7 is provided on the upright part 1 of the tower, it is possible to increase the distance between the power transmission line conductor 4 and the lightning arrester 5 that was cut off by fire without increasing the length of the arm 2 of the tower. Even if the transmission line conductor 4 sways greatly due to wind,
There is no chance of a flashover causing another accident.
