Problems solved by technology
[0005] The purpose of the present invention is to provide a double-capacity power transformer with short-term emergency load capacity, so as to solve the problem of cooling the transformer by combining air cooling and water cooling in the prior art. The liquid will absorb heat and heat up during this process. When the transformer changes from low overload to high overload, the temperature of the coolant is too high, resulting in poor cooling effect of water cooling, which affects the overall cooling effect and makes the transformer unable to operate in a high overload state. question

The invention discloses a double-capacity power transformer with short-term emergency load capacity, which includes an oil tank, an iron core, a winding, and a cooling device installed on the oil tank. The cooling device includes a cooling main body and a temperature-sensitive transformer component. The cooling body cools the internal parts of the transformer to make them operate normally. The temperature-sensitive transformer component is connected to the cooling body and controls the cooling intensity of the cooling body. The temperature-sensitive transformer component can sense Temperature changes, and adjust the cooling intensity of the cooling body according to the temperature changes, so that the components in the transformer are always in a suitable temperature environment, so as to operate normally. By effectively sorting the cooling, the cooling device has the maximum and longest time The cooling capacity is optimized to meet the cooling requirements of long-term low overload and short-term high overload conditions, so that the transformer has long-term low overload capacity and short-term emergency load capacity.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to a double-capacity power transformer with short-term emergency load capacity. Background technique [0002] During the operation of the power grid, sometimes the transformer fails due to external environmental damage or the transformer itself, and other transformers cannot bear the load of the faulty transformer, resulting in the immediate shutdown of the entire power grid, resulting in serious losses. If each transformer in the power grid can be made to have a greater overload capacity, then when one transformer is out of operation due to a fault, the other transformer can bear all the load of the faulty transformer in a short time, and the power grid can be maintained for a period of time. It can greatly improve the flexibility of power grid dispatching and reduce the failure loss of power grid operation transformers. [0003] The load operation capacity of a transformer i...
