Description
Technical field
The present invention relates to electrical equipment technical field, relates in particular to a kind of oil immersed type transformation with automatic heating device
Device.
Background technology
Oil-filled transformer is the indispensable equipment of power system.Electric insulation medium of the transformer oil as transformer,
Its performance directly affects transformer station high-voltage side bus safety, but the appearance with extreme weather in recent years, and many areas have occurred minimum gas
Situation of the temperature less than transformer oil condensation point, transformer cannot start, and affect the normal work of power system.
Content of the invention
The technical problem to be solved in the present invention and the technical assignment for proposing are prior art to be improved and is improved,
The oil-filled transformer that a kind of band moves heater in vain is provided, so that reach when temperature is low also can normal starting transformer, it is ensured that
The purpose that power system normally runs.
To achieve these goals, the technical scheme is that：
A kind of oil-filled transformer with automatic heating device, including transformer tank, the transformer body in the transformer tank,
Transformer oil in injection transformer casing, the oil-filled transformer are additionally provided with heater, and the heater includes setting
In the heating under casing and vertically disposed heating high case between transformer body for becoming village device bottom portion, the heating under casing and
Heating high case is provided with heating element heater, is provided with according to the work of transformer tank Oil-temperature control heating element heater in the transformer tank
Temperature controller, the heating under casing are arranged in transformer tank body and are fixed on the bottom surface of transformer-cabinet, the heating
High case is connected with heating under casing.
The technical program can be heated to transformer oil when temperature is less than transformer oil freezing point, until transformation
Device oil melts and can be with starting transformer, so as to ensure the normal operation of power system.
Used as the improvement to above-mentioned technical proposal, the heating element heater is the finned heating tube of far infrared radiation.
As the improvement to above-mentioned technical proposal, the heating element heater in the heating under casing and heating high case is arranged at for simultaneously
The heating tube of row.Heating tube is arranged side by side, and high and low position is heated simultaneously, the transformer oil in transformer tank is uniformly heated,
Hot-spot is prevented, transformer is affected.
Compared with prior art, the present invention has the advantages and positive effects of：
The oil-filled transformer with automatic heating device of the present invention, can be when temperature be less than transformer oil freezing point to change
Depressor oil is heated, until transformer oil melt and can be with starting transformer, so as to ensure the normal operation of power system.

The temperature controller 5 of the work of transformer tank Oil-temperature control heating element heater 6, the heating under casing 3 are arranged in transformer tank body simultaneously
It is fixed on the bottom surface of transformer-cabinet, the heating high case 4 is connected with heating under casing 3.
The technical program can be heated to transformer oil when temperature is less than transformer oil freezing point, until transformation
Device oil melts and can be with starting transformer, so as to ensure the normal operation of power system.
The heating element heater 6 is the finned heating tube of far infrared radiation.
Heating element heater 6 in being arranged at the heating under casing 3 and heating high case 4 is heating tube side by side.Heating tube side-by-side
Arrange, and high and low position is heated simultaneously, the transformer oil in transformer tank is uniformly heated, and prevents hot-spot, affects transformation
Device.
Compared with prior art, the present invention has the advantages and positive effects of：
The oil-filled transformer with automatic heating device of the present invention, can be when temperature be less than transformer oil freezing point to change
Depressor oil is heated, until transformer oil melt and can be with starting transformer, so as to ensure the normal operation of power system.
