(4) Main technologies and parameters (as shown in the table below)
structure
The primary coil of LR-35 and LRD-35 current transformers is the conductive rod of the oil switch bushing. The iron core is made of cold-rolled oriented silicon steel sheets in a circular shape and undergoes secondary crystallization heat treatment. The secondary coil is wrapped around the iron core with insulated copper wire, and its outer layer is wrapped with diagonal cloth tape. The entire product is impregnated with insulation paint, and the nameplate is wrapped around the product with diagonal tape.

Initial marking:
The primary side is P1, and the secondary sides are S1 and S2.
When a current flows, the secondary must not open circuit, otherwise high voltage will be generated.
