Abstract

PURPOSE: To simplify the structure and to enanble to operate securely by interlocking a counter by utilizing the force, etc., with which an iron piece is attracted by an iron-made horseshoe body, surrounding a conductor, to its ends when a lightning current flows through the conductor.
CONSTITUTION: The counter consists of conductor 1, horseshoe soft iron 2, iron piece 3, spring 4, and counter 5. When a current flows through conductor 1, iron piece 3 is attracted by horseshoe soft iron 2 and counter 5 is interlocked by spring 4 connected to iron piece 3. Therefore, this simple structure performs secure operation. Adjusting the strength of the spring manufactures the surge counter that corresponds to various voltage peak values. In addition, when a lightning current flows through the conductor, repulsive force generated between counter iron pieces located near the conductor can interlock the counter.
