Further, the binding both after being pasted onto first winding for the ease of hoisting connecting piece limits described primary
Binding layer is additionally provided with outside winding.
Further, be fixed in first winding to be more favorable for hoisting connecting piece, limit the hoisting connecting piece as
Arc structure, the radian of hoisting connecting piece and the outer diameter of first winding are consistent.
Further, in order to guarantee the reliable location of first winding, and also to guarantee that positioning cantilever can reliably weld
On hoisting connecting piece and it is firm fix, limit positioning cantilever arrangement "Z"-shaped, wherein the one of Z-shaped positioning cantilever
A support arm is connect with the hoisting connecting piece, another support arm of Z-shaped positioning cantilever is connected with the positioning inserts.
Further, in order to guarantee that entire positioning device can stablize fixation in voltage transformer, it is embedding to limit the positioning
Part, which is equipped with, to be cooperated with screw rod with the threaded connection hole that entire positioning device is fixed；In order to more accurately fix the positioning
Device, limits the threaded connection hole and the primary connection inserts is coaxially arranged.
Further, the high-voltage end that the positioning inserts form voltage transformer is limited, high-voltage end and low-pressure end are protected at this time
Certain insulation distance has been held, the stable operation of electrical system is conducive to.
