Shield plates for transformer core - are cut into complementary sections with centre limb section cut along diagonal with meshing cut outs and protrusion

摘要

Shell plates for transformer cores cut into two sections to form two windows. The centre limb of each plate has a diagonal cut to be matched in pairs. The yoke sections are inserted into the stack alternately from opposite directions. The diagonal face of each half of the centre limb is made is cut-outs (7a) at the internal corners and protrusions (6a, 6b) at the free ends to lock with their counter parts when the stack is built up. The outer limbs of the core are chamfered at the edges opposite the internal cut-outs or protrusions of the centre limb. The method in which the internal sections of the centre limb. The method in which the internal sections of the centre limb mesh will reduce magnetic leakage in the core.
