Oil-immersed transformer with automatic heating device

Abstract

The invention relates to a transformer, in particular to an oil-immersed transformer with an automatic heating device. Transformer oil serves as an electrical insulation medium of the transformer. When the air temperature is lower than a condensation point of the transformer oil, the transformer cannot be started, and the normal work of a power system is affected. The oil-immersed transformer comprises a transformer box, a transformer body arranged in the transformer box and the transformer oil injected into the transformer body and is characterized in that the oil-immersed transformer is further provided with the automatic heating device. The automatic heating device comprises heating boxes arranged at the bottom of the transformer box, heating elements located in the heating boxes and a first temperature controller controlling the work of the heating elements according to the oil temperature of the transformer box. A plurality of heating boxes arranged at intervals are arranged at the bottom of the transformer box, and the top faces of the heating boxes are tightly adhered to the bottom face of the transformer box. The oil-immersed transformer can heat the transformer oil when the temperature is lower than the condensation point of the transformer oil till the transformer oil is melted and the transformer can be started, thereby ensuring the normal operation of the power system.

Description

technical field [0001] The present invention relates to a transformer. Background technique [0002] Oil-immersed transformers are indispensable equipment in power systems. Transformer oil is used as the electrical insulation medium of transformers, and its performance directly affects the safety of transformer operation. However, with the emergence of extreme weather in recent years, the lowest temperature has been lower than the freezing point of transformer oil in many areas, and the transformer cannot be started, which affects the power system. normal work. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide an oil-immersed transformer with an automatic heating device, so as to start the transformer normally even when the temperature is low and ensure the power The purpose of normal operation of the system. For this r...
