(Summary description)(1) There are no fuses on the high and low voltage sides of the low price 10kv transformer. Although some have been equipped with drop-out fuses and horn insurance, most of the fuses are replaced by aluminum or copper wires, so that when the low-voltage short circuit or overload occurs, the fuses cannot be blown normally and the transformer will be burned.

(1) There are no fuses on the high and low voltage sides of the low price 10kv transformer. Although some have been equipped with drop-out fuses and horn insurance, most of the fuses are replaced by aluminum or copper wires, so that when the low-voltage short circuit or overload occurs, the fuses cannot be blown normally and the transformer will be burned.
(2) The high and low voltage fuses of the transformer are improperly configured. The fuses on the low price 10kv transformer generally have a phenomenon that the configuration is too large, and the transformer will be burned when it is seriously overloaded.
(3) The three-phase load is unbalanced. In some rural areas, due to the many and messy lighting lines, most of them use single-phase power supply, coupled with the arbitrariness of jumpers during construction and inadequate management, resulting in the off-phase operation of the load of the low price 10kv transformer. Long-term use causes the insulation of a certain phase coil to age and burns out the low price 10kv transformer.
(4) Oil leakage is the most common appearance abnormality of the low price 10kv transformers. Since the transformer body is full of oil, there are rubber beads and rubber pads at each connection part to prevent oil leakage. After a long time of operation, some rubber beads and rubber pads in the transformer will age and crack, causing oil leakage. As a result, the performance of the insulation will decline after being damp, the discharge will be short-circuited, and the transformer will be burned.
(5) Weather reasons. Most of the high and low voltage lines of the low price 10kv transformer are introduced by overhead lines, because the arrester is not put into operation in time or the 10kV arrester is not installed. Severe weather such as thunderstorms caused voltage overload problems, and the low price 10kv transformer was burned when struck by lightning.
(6) The iron core is grounded at multiple points.
(7) Man-made damage.
