Abstract

PURPOSE: To provide an arrester, with a full margin of function durable for the conduction of big capacity further with a long period reliability in small size, by such construction that, with the firm voltage divided by a first and second non- linear resistance element, a parallel connection be made between the second element and the discharge gap of rearcing type.
CONSTITUTION: In series to a first element 1, is connected a parallel circuit comprising a second element 2 and a rearcing gap 3. They are housed in a container to construct the arrester. And the gap 3, which is connected to parallel to the second element 2, is of such construction that, with two sheets of main electrodes 6 arranged on an arc extinction plate 5, having a protrusion likely as tooth shape, a high voltage side terminal 7 and an earth terminal 8 are provided respectively in each of the main electrodes 6, and a main gap 9 of the facing main electrode 6 provides a groove 10, with an irradiating piece 11 installed so as to face the main gap 9. And in the bottom of the two sheets of the main electrodes 6 and an auxiliary electrode 12, is provided a groove 14 of the letter "Y" shape, and another sheet of arc extinction plate 5 is covered on the arc extinction plate 5 to construct an arc extinction chamber. In this way, the arrester can be provided small in size further with a reliability for a long period.
