記載の耐雷用高圧カツトアウト。[Scope of Claim for Utility Model Registration] (1) In a high-voltage cut-out in which the main body is attached to a support 4 such as a steel tower that is installed on the ground and is itself in a grounded state, using the mounting bracket 3 provided on the main body 2, An insulating support stand 11 is attached to the above-mentioned mounting bracket 3, and furthermore, when a lightning surge enters the insulating support stand 11, the above-mentioned mounting bracket 3
Attach the arcing horn 12 on the ground side while maintaining an insulation distance l 1 , l 2 to the extent that flash short can be prevented between the arcing horn 12 and connect one end 12c of the installed arcing horn 12 to the current limiting element 19 on the cutout side. The discharge part 16 of the discharge electrode 16
A grounding wire 18 made of a covered wire that is grounded E2 separately from the grounding E1 of the support 4 is connected to the grounding terminal 17 which is opposed to the grounding wire A via a predetermined discharge gap G and is integrally provided with the arcing 12. Lightning-resistant high-voltage cutout characterized by connecting. (2) The insulating support stand 11 is formed of a substantially rectangular parallelepiped,
Mounting surfaces 11a are formed on the top and bottom of the mounting surfaces, and bolts 14 equipped with nuts 15 are fixedly fixed to the respective mounting surfaces.
A has a pair of parallel guide protrusions that engage with both sides 3d and 12b of the mounting bracket 3 or arcing horn 12 when the mounting bracket 3 or arcing horn 12 is attached to the mounting surface using the bolt or nut. 11b. The high-voltage cutout for lightning protection according to Claim 1 of the Utility Model Registration Claim.
