SECONDARY VOLTAGE INSULATING BUSHING WITH LOCKING MEANS AND SEALING APPLIED TO A POWER TRANSFORMER

摘要

it is a secondary voltage insulating bushing (10) of the type applied in a power transformer (tp); said secondary voltage insulating bushing (10) is comprised of an insulating body (20), the extreme portion of which (20a) comprises the receiving head (20b) of the terminal (30) with connecting screw (31), conductor (40), in addition respective sets of lock nuts and washers (31a) and (40a); said secondary tension insulating bushing (10) comprises insulating body (20) made of epoxy resin and which is assembled next to the power transformer (tp) by tightening the nut (52) and fixing washer (51), all made in epoxy type insulating material; on the flat face (52a) of the nut, a set of non-return latches (52c) is applied, evenly distributed so that, after threading on the portion (21a), said nut (52) is locked just above the face (51d ) of the fixing washer (51) through a set of cavities (51e) arranged radially.
