Description
Technical Field
The utility model relates to a removable finned radiator relates to radiator technical field.
Background
The finned radiator is a cooling device matched with an oil-immersed power transformer, a reactor and the like for use, can meet the requirements of the transformer on three functions of self cooling, air cooling and forced oil air cooling, and is suitable for the heat dissipation requirements of 35kV, 66kV, 110kV, 220kV and 500kV oil-immersed transformers and reactors. When the oil-immersed power transformer operates, the internal winding, the iron core and other components generate loss, the loss is converted into heat and is transferred to the oil tank wall through the heat conduction and convection action of transformer oil, and the temperature of the winding, the iron core, the oil tank wall and the oil surface is increased. The temperature rise directly affects the service life of the winding insulation material, so the temperature rise must be controlled within a certain range, and the heat dissipation by adopting a radiator is necessary. The finned radiators with corresponding quantity are arranged around the transformer oil tanks with different capacities and different voltage grades according to the heat loss of the transformer oil tanks, and especially, when the capacity of the transformer is gradually increased, a large radiator is required to be selected to radiate enough heat.
The cooling device of the transformer is a device which can radiate the heat generated by the loss of the transformer during the operation of the transformer so as to ensure the safe operation of the transformer. The working process of the finned radiator comprises the following steps: the hot oil at the upper part in the transformer oil tank enters the upper oil collecting pipe of the finned radiator, flows through the radiating fins and then flows back to the oil tank of the transformer from the lower oil collecting pipe of the finned radiator. When hot oil flows in the radiating fins, the heat is transferred to the air, so that the purpose of radiating is achieved.
The full load or overload operation of transformers in general electric substations and transformer substations can be caused, and three major problems mainly occur:
first, the loss of the transformer increases: because the transformer is designed according to rated capacity, the economic operation balance point of the transformer is about 67 percent, and when the load of the transformer exceeds the rated capacity, the copper loss of the transformer is increased gradually according to the square relation;
secondly, the output voltage of the transformer is reduced: when the rated capacity of the transformer is exceeded, the secondary output voltage of the transformer is reduced, and when the output current reaches the short-circuit current, the voltage is reduced to zero;
third, the life of the transformer is reduced: the winding of the oil-immersed transformer is mostly composed of A-grade insulating materials, the heat-resistant temperature of the winding is about 105 ℃, the aging of the insulating materials is aggravated when the winding exceeds the temperature, and the transformer is overheated or even burnt out when the winding runs under full load or overload for a long time. Therefore, national grid companies now place the first place on safe operation of transformers.
At present, no matter the temperature rise of a transformer is controlled in a transformer substation, or the transformer is overhauled after long-term operation, a cooling device needs to be adjusted according to the actual operation condition of the transformer, for example, the number of radiating fins of a finned radiator is increased, and the radiating area of a single group of finned radiators is increased, so that the requirement of controlling the temperature rise of the whole transformer during operation is met. However, the finned radiators currently used in the power grid are conventional products, and if the finned radiators are replaced, the overall maintenance cost is high. A technical solution for realizing cooling regulation without replacing the finned heat sink is needed.
