故が発生する場合がある。 Surge arresters are used as a major lightning protection device for high-voltage power distribution lines, etc. They protect the insulation of electrical facilities by limiting the peak value of shock voltage that enters circuits due to lightning, etc., and reduce follow-on current for a short time. It has the function of restoring itself to its original state without disrupting the normal condition of the line. Currently, in order to protect the switch, a separate lightning arrester is often installed via a lead wire near the switch installation location, but even with this arrangement, the limiting voltage when the arrester operates Because voltage drops in the lead wires due to lightning discharge current are added to this, the abnormal voltage received by the switch often exceeds its insulation strength, leading to accidents. Therefore,
In order to expect even more effective protection, it is necessary to place a lightning arrester as close as possible to this switch. In addition, installation work for lightning arresters at switch facilities requires a considerable amount of labor because the lead wires on the track side and the wiring on the ground side are complicated, and past research shows that these lightning arresters are susceptible to moisture absorption, lead wire breakage, etc. Accidents may occur due to stains and damage caused by blows during construction.

In order to prevent damage to line-side equipment, the lightning arrester is connected close to the contact point, and by providing a dedicated installation space for the lightning arrester element, the switch is made larger.In order to prevent moisture absorption and damage to the lightning arrester, it is possible to A lightning arrester is installed in a dead space formed near the bushing inside the vessel body.
