Electric switch assembly, in particular medium voltage switching assembly

摘要

The switchgear has a bus bar (13) provided outside of a metallic housing (11) of a display (10). A terminal of a disconnecting switch/ground electrode switch (18) is directly connected with the bar over a rail. Another terminal of the disconnecting switch/ground electrode switch comprises a voltage converter (24) present in the housing for supplying electric voltage to the bar. A power switch (16) is connected with the bar and a current transformer (22). An air gap (L) or an insulator (I) is present between the terminal of the disconnecting switch/ground electrode switch and the transformer.
