Technical Field

[0001] The utility model belongs to the technical field of box-type transformers, in particular to a movable oil collecting pan of a box-type transformer. Background Art

[0002] With the rapid development of the new energy industry, the installed capacity of wind power and photovoltaic power continues to increase. The capacity of new energy units is relatively small, and the demand for box-type transformers, as essential power transformation equipment, has surged. Box-type transformers are prone to oil leakage due to incorrect installation procedures, loose bolts, oil leakage from conductive rods, bolts, and pipe threads, rough equipment processing, poor sealing, and radiator oil leakage. The radiator's heat pipe has seams. The steel pipe is flattened and then stamped. The bending and welding parts of the heat pipe will leak oil.

[0003] As the box-type transformer operates for a period of time, the defects that lead to oil leakage gradually become apparent. Common phenomena such as oil seepage, oil dripping, and oil leakage occur during the operation of the box-type transformer. The oil leakage of the box-type transformer not only seriously pollutes its appearance and the foundation of the box-type transformer, but also causes soil and land pollution. Utility Model Content
