Testing instrument transformerDisassembly steps recommended by the manufacturer for the transformer:
When a small transformer (≤ 2kV · A) Short circuit between the internal turns of the winding, internal disconnection but no broken end can be found, short circuit or burnout between the windings, you need to remove the old winding and rewind it.
Before removing the transformer core, the original data must be recorded as the basis for rewinding the transformer. The data to be recorded include: nameplate data (type, number of phases, capacity, primary and secondary voltage, connection group, insulation class, etc.), winding data (wire size, number of turns, size, lead size and length) Etc.), core data (shape, size, thickness, stacking sequence, stacking method, etc.).
To remove the iron core: Remove the housing and terminals→Remove the iron core clamp plate or iron yoke→Lever up the bonded silicon steel sheet with a screwdriver→Loosen the silicon steel sheet one by one with wire cutters→Surface silicon steel plate→Stack the silicon steel plates layer by layer and keep them properly.
For specific disassembly, the core can be fixed on a bench vise. After removing the iron core splint, first use a screwdriver (flat head) to cut into the overlapping seam of the chip, cut a circle around the iron core, cut off the adhesion of the first few silicon steel sheets, and then clamp the silicon steel sheets Use wire cutters to swing the middle position of the silicon steel sheet slightly to the left or right to clamp them one by one.
In the process of disassembling the iron: When using a screwdriver to pry open the silicon steel sheet, it should be handled gently, the force should be even, try to pull it to the position of the knife, do not pull it hard, Be careful not to damage or deform the silicon steel plate.
