DEVICE FOR MOUNTING/DISMOUNTING CURRENT MEASURING TRANSFORMERS, VOLTAGE MEASURING TRANSFORMERS AND COMBINED CURRENT/VOLTAGE MEASURING TRANSFORMERS IN HIGH VOLTAGE ELECTRIC SUBSTATIONS

摘要

The invention relates to a device for mounting/dismounting current, voltage or combined current/voltage transformers in high voltage electric substations. According to the invention, the device comprises two symmetrical base plates () whereon there are welded four hanging ring (), two mobile plates () whereon there is fastened the base of a transformer and which help the positioning on a supporting metal frame, four cranks () with threaded rods for sliding the mobile plates () backwards and forwards, four inner thread metal pieces () welded on the base plate (), four metal pieces () fixed on the mobile plates () by welding, wherein there are introduced the ends of some threaded rods allowing the rotation and advance/ withdrawal of the mobile plates (), four metal plates () which do not allow the mobile plates () to go out from the space created in the base plates () by milling, twelve steel pieces () welded by six to the two base plates () wherethrough there pass six screws () with nut in their ends and which play the role of maintaining the base plates () in close proximity of each other.
