の物質を活性層とする避雷管のグロー放電に於ける放電
維持電圧は５０Ｖから１１０Ｖに限定される。It is known that in the past, alkali metals or alkaline earth metals having a low work function have been used as the active layer on the surface of the discharge pole in this type of lightning arrester. However, the discharge sustaining voltage during glow discharge of a detonator having an active layer made of such a material with a low skew function is limited to 50V to 110V.

ている。Inserting lightning arresters into communication lines, control lines, power lines, etc. [2.
It is used to protect the line from voltage, but without a detonator, DC or AC voltage is constantly applied to the line.
線路に異常電圧が到来して避雷管が動作し７、異常電圧

無くするだめには避雷管のグロー放電における放電維持
電圧を上げる必要がある。When an abnormal voltage arrives on the line, the arrester is activated, and after the abnormal voltage disappears, the arrester immediately stops operating, but the voltage constantly applied to the line is high, and the arrester is activated. If the discharge sustaining voltage of the tube's glow discharge is low, the detonator will continue to operate, causing a line failure. In order to eliminate such troubles, it is necessary to increase the discharge sustaining voltage in the glow discharge of the detonator.

を奏す。The present invention provides for alkali metals or alkaline earth metals,
By providing a mixture consisting of 5% to 70% silicon by weight on the surface of the discharge electrode, it is possible to increase the discharge sustaining voltage in glow discharge from 10V to 300V, and silicon is also mixed. Since the temperature of the electrode can be raised to 500° C. or higher, the active substance can firmly adhere to the electrode surface.
