Title: Tank-shaped lightning arrester
Inventor: KOMATSU KATSURO
IPC: H01T4/20
Filed: 1993-06-18
Abstract: PURPOSE:To make uniform the voltage distribution on nonlinear element groups by arranging the spherical part of a spherical crown-shaped shield in such a manner that it is opposing to an earth tank. CONSTITUTION:The capacitance between a nonlinear element group and an earth tank 3 is not masked completely by the spherical crown type shields 10a and 10b arranged on the circumference of the nonlinear element group 1, and a capacitance is generated between the vicinity of position of the spherical crown type shields 10a and 10b of the nonlinear element group 1. As a result, the capacitance between the low voltage side of the nonlinear element group 1 and the spherical crown type shields 10a and 10b becomes smaller, and the capacitance between the nonlinear element group 1 and the earth tank 3 becomes larger. As a result, the capacitance distribution of the nonlinear element group approaches an ideal state. Consequently, the voltage distribution on the nonlinear element group 1 can be made uniform along axial direction.
