OIL FILLED TRANSFORMER

摘要

An oil filled transformer is provided to improve a heat dissipation effect by making an external case connection part of a top guide tube and a bottom guide tube tilted according to a flow direction of oil. An external case(100) is filled with oil. A radiator(200) has a plurality of radiation plates(210). A plurality of radiation plates emits a heat by a heat exchange with the oil filled inside the external case. A top connection tube(300) is connected to a top space of the external case. The top connection tube comprises an inflow end(310) and a distribution end(320). The inflow end is downwardly tilted from the external case to the radiation plate. The distribution end is extended from the inflow end to a top end of the radiator. A bottom connection tube(400) is connected to a bottom space of the external case. The bottom connection tube comprises an outflow end(410) and a guide end(420). The outflow end is downwardly tilted from the radiation plate to the external case. The guide end is extended from the outflow end to a bottom end of the radiator.
