Problems solved by technology
[0003] The purpose of the present invention is to provide a cooling method for flexible straight transformers in the internal circulating water cooling system, which solves the problem that the flexible straight transformers equipped with water coolers must be regularly powered off to clean up impurities and scale. For operation needs, the external cooling system cools the closed pure water in the internal cooling system through a closed cooling tower to ensure long-term stable operation of the transformer, reduce maintenance costs, and solve the above-mentioned problems in the background technology

Embodiment Construction
[0016] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0017] A method for cooling a flexible transformer with an internal circulating water cooling system. The internal circulating water cooling system of the flexible transformer is divided into an internal cooling system and an external cooling system. The internal cooling system is connected with a water cooler to form a closed system. The internal cooling system is filled with It is pure water, and the external cooling system cools the pure water in the internal cooling system through a closed cooling tower.
[0018] The internal cooling system 3 includes a main water pump 6, a degassing tank 7, a filter 8, a raw water tank 9, an ion tank 10, an expansion buffer tank 11 and a nitrogen cylinder 12, and the external cooling system 4 includes a closed cooling tower 13 and a fan 14 ; The heat in the flexible straight transformer 1 is carried out oil...

The invention relates to a cooling method for a flexible direct current transformer of an internal circulation water cooling system, and belongs to the technical field of transformer cooling. According to the technical scheme, the internal circulation water cooling system of the flexible direct current transformer is divided into an internal cooling system and an external cooling system, the internal cooling system and a water cooler are connected to form a closed system, pure water is filled into the internal cooling system, and the external cooling system cools the pure water in the internal cooling system through a closed cooling tower. The cooling method has the beneficial effects that the cooling requirement of the flexible direct current transformer can be met, the cooling efficiency cannot be reduced due to impurities and scale generated in the operation period, and the situation that the transformer is powered off due to regular cleaning and maintenance of the water cooler is avoided; the cleaning cost of the water cooler is saved, and loss caused by line outage due to power failure of the transformer is avoided; the noise level is low during operation, and noise pollution is reduced.
Description
technical field [0001] The invention relates to a method for cooling a flexible straight transformer in an internal circulating water cooling system, and belongs to the technical field of transformer cooling. Background technique [0002] my country has a vast coastline, and is currently vigorously developing clean energy such as wind power and solar power. Flexible direct current transmission has great potential for development in my country. In addition, the urban power grid also faces problems such as excessive short-circuit current and insufficient power supply capacity. Flexible DC transmission has its unique advantages in solving these problems. As an important equipment of the flexible direct current transmission system, the flexible direct current transformer plays a vital role in the normal operation of the direct current transmission system. The transformer cooler is an important guarantee for the reliable operation of the transformer. Water is preferred as the ...
