Summary:PROBLEM TO BE SOLVED: To provide a lighting arrester excellent in safety and reliability, which is capable of quickly discharging out a high-temperature/high-pressure gas flow generated by an internal arc and surely guiding it to an external path so as to protect an insulating tube against damage when a ground fault occurs. SOLUTION: A pressure releasing opening 19a and a sloping plate 20a located at a position opposite to the opening 19a in a radial direction are provided to a guide 20 inside an arc guide 19. When an arc occurs inside the insulating tube 13 to generate a high-temperature/high-pressure gas flow, the gas flow breaks pressure release plats 15 as it is passing through the communicating openings 14a and 14b of lids 14 and flows into guides 20 inside the arc guides 19. At this point, the gas flow hits against the sloping plates 20a and then is guided to the openings 20b and pressure release openings 19a of the guides 20. COPYRIGHT: (C)2003,JPO
