摘要： PROBLEM TO BE SOLVED: To loosen an electric field in a lightning impulse withstand voltage test, and improve insulation reliability and compactness by providing a non-linear resistance material on an inner face of an insulation container.SOLUTION: A high voltage side stationary electrode 6 is provided at an upper part of an inner surface 11 of an insulation container 5, and a ground side stationary electrode 7 is provided at a lower part of the inner surface 11 of the insulation container 5. A non-linear resistance material 13 is applied to the inner surface 11 of the insulation container 5 until it is continued to the high voltage side stationary electrode 6 and reaches the ground side stationary electrode 7. The high voltage is necessarily applied to the non-linear resistance material 13 when the high voltage is applied to the high voltage side stationary electrode 6 during a lightning impulse withstand voltage test. Accordingly, the resistance material 13 reliably actuates a non-linear resistance characteristic, and therefore, an electric field strength heightened at a peripheral section 10 of the high voltage side stationary electrode 6 can be reduced.
