Abstract
An elbow type pluggable underground distribution transformer structure comprises a fuel tank casing, a case cover, coils and an iron core; the coils and the iron core are arranged inside the fuel tank casing; plural ripple type cooling fins are assembled into the fuel tank casing in a welding mode; every cooling fin is formed by steel plates; a through hole is formed in a long side of the fuel tank casing; a high voltage elbow type plug base flange is welded to the through hole position; at least three elbow type plug bases are arranged on the high voltage elbow type plug base flange. The elbow type pluggable underground distribution transformer structure has the advantages of enabling underground distribution transformer dual requirements for intensity and heat dissipation to be satisfied due to the fact that the ripple type cooling fins are welded to be manufactured into a case body; being convenient to overhaul and greatly improving the water proof effect due to the facts that a high voltage connector which is in a waterproof sealing elbow type pluggable structure is arranged on the case body and a low voltage connector sealing case is arranged on the case cover to achieve connection and expansion of high and low voltage circuits; meanwhile achieving protection of a transformer body for a long time due to a three-phase high voltage fuse protector which is arranged on the case cover and being suitable for the development direction of the underground distribution network technology.
