Abstract

A gas insulated apparatus is provided, which can certainly traps conductive extraneous particles entered in a grounded tank to render them harmless, whereby the dielectric ability of the apparatus is improved even under the condition that a direct current voltage of the negative polarity is applied to a high voltage conductor. According to the invention, in the gas insulated apparatus with the grounded tank. 1, the conductor 3 arranged in the grounded tank 1 and flowing a current therethrough, and the insulator spacers 2 for supporting and fixing the conductor 3 in the grounded tank 1, in which the insulator spacers being arranged, spaced in a predetermined interval in the longitudinal direction of the conductor 3 and the grounded tank 1 being hermetically sealed and filled with insulating gas, the tapered member 5 whose diameter gradually decreases as the distance from the insulator spacer 2 is mounted on the conductor 3, and the projection 6 (or depression) is disposed on the conductor 3 on the side of the smallest diameter of the tapered member 5.
