The application provides an excitation becomes cabinet body structure can improve the heat-sinking capability of the cabinet body.
The excitation transformer is a device specially used for providing a three-phase alternating-current excitation power supply for a generator excitation system, in the working process of electrical equipment such as the excitation transformer and the like, the generated static electricity is easy to adsorb dust of the surrounding environment, and as the specific resistance of most of dust is not high, and the dust has the charge property and the water absorption property, the dust is easy to agglutinate and settle around the electrical equipment, so that the insulation strength of the electrical equipment is damaged, electrical breakdown short-circuit accidents are easy to cause, and meanwhile, some dust is also accumulated in an electronic board, so that electrical malfunction, short circuit and the like are caused, and the safety operation of the electrical equipment is greatly damaged. Therefore, the excitation transformer substation for storing the electrical equipment such as the excitation transformer substation is usually installed in a room with a relatively closed operation environment, so that the damage of dust deposition on the electrical equipment is reduced.
Referring to fig. 1 and 2, an excitation transformer cabinet structure in the present application includes: the cabinet body 1, the first protection plate 2, the second protection plate 3 and the exhaust passage 4;
the exhaust passage 4 is arranged in the cabinet body 1 and used for exhausting air in the cabinet body outwards through an exhaust port of the exhaust passage 4; the second protection plate 3 is arranged outside the cabinet body 1 and used for protecting the cabinet body 1; first guard plate 2 sets up in the cabinet body 1 outside, and first guard plate 2 sets up the position at the cabinet body 1 outside and corresponds with the position of gas vent, and first guard plate 2 is grid network formula structure for it is perpendicular with the plane that first guard plate 2 corresponds through the exhaust air flow direction of gas vent exhaust.
The utility model provides an excitation becomes internal portion of cabinet and is provided with the temperature controller, when detecting that the temperature of the internal portion of cabinet reaches the preset threshold value, the heat abstractor work that the temperature controller control is connected with it to accelerate the process of the internal portion of cabinet and external heat transfer, thereby reach and accelerate radiating purpose. The air outside the indoor cabinet 1 is heat-transferred with the outdoor air or a dedicated ventilation duct and the outdoor air or a dedicated cooling device to reduce the temperature of the indoor air, and the cooling method of the indoor hot air is not limited. In summary, the ambient temperature in the room affects the cooling capacity in the cabinet 1.
Because excitation transformer's operating temperature is comparatively stable, uses the cooling method of nature forced air cooling usually, dispel the heat through the louvre of the second guard plate 3 of installing on the cabinet body 1 outside promptly, through the inside hotter air of the exhaust cabinet body 1, inhale the cabinet body 1 outside around colder air to reach radiating purpose.
