Baoding dry type transformer is a transformer with iron core and windings not impregnated in insulating oil. If the baoding dry type transformer is overload for a long time, it will cause coil heating and gradually aging insulation, resulting in short circuit between boxes, short circuit between phases or short circuit on the ground and oil decomposition. Aging insulation of iron core or damage of clamping bolt sleeve will cause great eddy current in iron core and cause long-term heating of iron core and aging insulation. When overhauling the lifting core of transformer, attention should be paid to protecting coil or insulating sleeve. If any damage is found, it should be dealt with in time.
In order to ensure the safe operation of baoding dry type transformer, the maintenance method of baoding dry type transformer is given.
1. Clean porcelain bushing and transformer coil to prevent creeping
2. Check whether the coil has cracks and discharge marks. If so, contact the transformer manufacturer in time for testing to determine whether it can be put into operation again
3. Check whether the silicone cushion is aging and invalid, and replace it in time.
4. Check whether all fasteners of the transformer are tightened to prevent coil displacement and excessive noise and performance degradation of baoding dry type transformer.
5. Check whether the electrical connection bolts are tight to prevent excessive contact resistance and ablative connection from causing accidents
6. Check whether the electrical connection is corroded and clean to prevent excessive contact resistance.
7. Clean the dust and foreign matters on the core to avoid multi-point grounding.
8. Check the insulation distance of high-voltage leads to ensure the safety of electricity use.
9. Check whether there are holes in the shell to prevent animals from entering the transformer room.
Check whether the transformer fan can operate normally.
11. Measure the insulation of the core to the ground and the coil to the ground to ensure the insulation reliability of baoding dry type transformer.
12. Check whether the transformer chamber is closed for reliable operation.
13. Check whether the on-load switch can operate reliably.
Baoding dry type transformers rely on air convection for natural cooling, or increase fan cooling, mostly used in high-rise buildings, high-speed charging stations and local lighting, electronic lines and other small capacity transformers.
