Abstract
The utility model belongs to the field of a transformer and particularly relates to a dry-type transformer. The dry-type transformer comprises a base, an iron core, a low-voltage winding, a high-voltage winding, epoxy resin poured bodies, a ventilating air flue, a temperature sensor and a temperature controller. The iron core is arranged on the base; the circumferential direction of the iron core is provided with the corresponding low-voltage winding and high-voltage winding from inside to outside; the epoxy resin poured bodies are respectively arranged outside the low-voltage winding and the high-voltage winding; the ventilating air flue is positioned between the low-voltage winding and the high-voltage winding; and the temperature sensor is positioned between the iron core and the low-voltage winding and is connected with the temperature controller. The dry-type transformer is characterized by also comprising a refrigerating air blower, wherein the refrigerating air blower is fixedly arranged on the base and is connected with the temperature controller. The dry-type transformer has a good immediate cooling effect; when the overload requirement is higher, cold air is blown to the ventilating air flue to carry out cooling by starting a refrigerating air blowing function of the refrigerating air blower; the load capacity of equipment is improved; and the service life of the equipment is prolonged.
Description
Technical field
The utility model belongs to field transformer, relates in particular to a kind of dry-type transformer.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, be divided into according to the difference of the type of cooling: dry-type transformer and oil-filled transformer, dry-type transformer is that a kind of iron core and winding are not immersed in the transformer in iknsulating liquid, there is no the problems such as fire, blast, pollution for oil-filled transformer, generally be used for hospital, school, residential quarters, industrial and mining enterprises.Loading condition before the overload capacity of dry-type transformer and ambient temperature, overload, the insulating radiation situation of transformer and heating time constant etc. are relevant, so the cooling performance of dry-type transformer is very important on the impact of its overload capacity.When normally moving, dry-type transformer rely on cross-ventilation to carry out cooling, dry-type transformer is undertaken cooling by opening blower fan when the overload demand is arranged, this moment, transformer was in the non-economy running status, can not be under this overload long-play, and the timely cooling effect of blower fan is not good, during overload, winding temperature usually destroys insulated part over the insulation tolerable temperature, causes the transformer cisco unity malfunction.
Summary of the invention
in order to solve the problems of the technologies described above, the utility model provides a kind of dry-type transformer, comprise base, iron core, the low pressure winding, the high pressure winding, epoxy resin poured body, ventilating air passage, temperature sensor, temperature controller, described iron core is arranged on base, described iron core circumferentially is provided with low pressure winding and the high pressure winding of mutual correspondence from inside to outside, be respectively equipped with epoxy resin poured body outside described low pressure winding and high pressure winding, described ventilating air passage is between low pressure winding and high pressure winding, described temperature sensor is connected between iron core and low pressure winding and with temperature controller, it is characterized in that: also comprise the refrigeration hair-dryer, described refrigeration hair-dryer is fixed on base and with temperature controller and is connected.
The beneficial effects of the utility model are: replace hair-dryer with the refrigeration hair-dryer, and the hair-dryer that will freeze is connected with temperature controller with ventilating air passage, when the overload demand hour by unlatchings freeze hair-dryer blowing function to ventilating air passage dry carry out cooling, the heat that produces in the transformer running timely discharge by force; Blow a cold wind over to ventilating air passage and carry out coolingly by the freeze refrigeration blowing function of hair-dryer of unlatching when the overload demand is larger, the heat that produces in the transformer running timely discharge by force, reach the purpose of cooling down.Instant cooling effect of the present utility model is fine, has improved the load capacity of equipment, has extended the useful life of equipment.
