Off-circuit tap changer is a switch for three-phase oil-immersed transformers with rated voltage of 10 kV and rated current of 63 A or less and 125 A. The secondary voltage can be adjusted by changing the number of turns in the primary winding of the transformer in the absence of excitation. The operating temperature range of the tap changer in oil medium is -25 ℃ to 100 ℃.

The non-excited disc tap changer is an embedded compound resistance transition structure, which integrates the functions of a tap selector and a shunt switch, and is provided with an independent oil chamber. The utility model has the advantages of simple structure, long service life, convenient installation and maintenance, etc. The technical performance of the switch conforms to the standards of IEC60214 and GB10230 "On-load Tap-changer".
