Wind cooling temperature lowering ventilation system for transformer

Abstract

The invention discloses an air-cooling temperature-dropping and air-changing system for a transformer, which is applied to the air-changing in a generator transformer and a transformer chamber. The system is characterized in that relying on an original air duct and an original air inlet in the transformer chamber, cooling plates are arranged on a main transformer, an air blower is arranged under the cooling plates of the transformer, a lower flow guiding screen is arranged in the lower air duct of the air blower, airflow fences are arranged among the cooling plates of the transformer above the air blower, and an upper flow guiding screen is arranged beside the cooling plates of the generator transformer, and surrounds the cooling plates of the transformer in the shape of the letter C; and a temperature sensor is arranged on the transformer, a humidity sensor is arranged in the chamber, and the running and the stopping of the air blower are set by a temperature-humidity controller. On the basis of the characteristics, the temperature-dropping and air-changing system of the indoor transformer, which has that advantages of the natural and compulsory temperature-dropping and air-changing, simple structure, and good heat dissipation and air-exchanging, is manufactured. By adopting the scheme, when the generator transformer carries out temperature reduction and energy conservation, the damage to the generator transformer caused by high load and high temperature, and the loss to the users caused by the damage of the generator transformer are reduced.

Description

Technical field [0001] The invention belongs to the technical field of transformer air-cooling and cooling, and in particular relates to a transformer air-cooling cooling and ventilating device, which is applied to main transformer cooling and indoor ventilation of the main transformer. Background technique [0002] More and more main transformers are moved indoors. Due to the small indoor air flow, especially in summer, the ambient temperature is high and the load is heavy. The large load causes the temperature of the internal conductor to rise, and the temperature rise increases the internal resistance of the conductor. The larger the temperature, the more severe the temperature rise, forming a vicious circle, resulting in the burning of the main transformer and the damage of the main transformer, resulting in large-scale user power outages and other adverse consequences Contents of the invention [0003] The purpose of the present invention is to design a transformer ai...
