Abstract

270,420. British Thomson-Houston Co., Ltd., and Heath, H. C. Feb. 9, 1938. Sliding switch-carriage arrange. ments.-To prevent corona discharge from the isolating contacts of trucktype switchgear an earthing sheath is provided within the insulating bushing surrounding the high potential conductor leading to such contacts. As shown in Fig. 1, an earthing sheath 14 is provided within the insulating bushing 7 surrounding the conductor 6 leading to the contact 5 on the movable truck member which co-operates with a contact 2 supported at the end of a cylindrical insulator 3 carried by the frame 1 of the fixed switchgear member and separated from the bushing 7 by an air space. Layers of insulating tape 12, 13 are interposed between the sheath 8 and conductor 6, the remaining space within the insulator 7 having a compound filling 16. Where the truck member is provided with double-ended removable plugs of the form shown in Fig. 2, the earthing-sheath 14<1> lies within the insulating bushing 7<1> and has tags 15<1> projecting therethrough for making the earth connections. To even out the potential gradient between the high potential conductor and the earth shield, condensers may be embedded within the insulating material. Specification 160,031 is referred to.
