介して大地に流すようにした避雷装置に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a lightning arrester for a power transmission tower, and more specifically, a lightning arrester for a power transmission tower or an overhead ground wire that guides a lightning strike to a lightning rod and directs lightning current to a power transmission tower. This invention relates to a lightning arrester that allows lightning current to flow to the ground via a separately provided conductor instead of flowing through it.

従来、送電鉄塔、あるいは架空地線に雷撃を受けたとき
、その雷電流は送電鉄塔を介して大地に流入するように
雷電流回路が構成されている。(Prior Art) Conventionally, lightning current circuits have been configured so that when a power transmission tower or an overhead ground wire is struck by lightning, the lightning current flows into the ground via the power transmission tower.

不平衡絶縁設計等の耐雷対策が実施されているが充分な
効果が得られていないのが現状である。As mentioned above, in the case of a method in which lightning current flows into the ground through the power transmission tower when a power transmission tower or overhead ground wire is struck by lightning, the electric resistance of the tower members causes the lightning current to flow through the power transmission tower, If the lightning current flowing through the transmission tower or the wave front steepness exceeds the design value, a potential difference will occur that exceeds the dielectric strength of the insulator device that insulates between the transmission tower and the transmission line. Reverse flash faults may occur in insulators, etc., resulting in power outages, circuit breakers, etc.
Or there was a problem of damaging transformers etc. Therefore, reduction of the grounding resistance of transmission towers, multi-stranding of overhead grounding wires,
Although lightning protection measures such as unbalanced insulation design have been implemented, the current situation is that sufficient effects have not been achieved.

The technical problem to be solved is to prevent the electrical potential of the power transmission tower from increasing by passing the lightning current through a lightning current conductor to the ground so that the lightning current does not flow through the power transmission tower itself.
