Abstract
The utility model relates to an oil immersed transformer without an oil storage tank for replacing an original structure. A metal elastic element is directly arranged in a transformer body. The expanding and shrinking function of the metal elastic element is used for realizing the automatic regulation and compensation of the volume change of transformer oil for the oil immersed transformer because of the temperature change of environment. Thus, the oil storage tank of the oil immersed transformer is canceled, the contact of the transformer oil and air is avoided, and the full seal of the oil immersed transformer is realized. Meanwhile, other functions and the application mode of components of the oil immersed transformer are maintained. Thus, the oil immersed transformer has simple, practical and safe manufacture, installation and operation.
Description
Affiliated technical field
The utility model relates to a kind of no oil conservator oil-immersed type transformer, this transformer relies on the swollen function that contracts of bellows-type metallic elastic component to realize the automatic adjusting compensation that right oil volume changes, thereby cancellation transformer oil conservator, reduce the transformer manufacturing cost, improve the transformer quality, reduce operation maintenance.
Background technology
At present, on oil-immersed type transformer, generally adopt oil conservator to regulate the transformer oil change in volume that compensation causes because of variation of ambient temperature.These oil conservators generally include a capsule or expansion gear, and make the pillow tubbiness and hang and to be installed in the oil-immersed type transformer top.This method not only makes the complex structure of oil-immersed type transformer, external electrical insulation distance anxiety, and make the transformer manufacturing cost significantly increase, the operation maintenance very complicated.
And the bellows-type metallic elastic component has the swollen function that contracts of obvious results, and this function can realize the volume-adjustment to the liquid goods and materials.The present invention utilizes this characteristic of bellows-type metallic elastic component to realize automatic adjusting compensation method to the transformer oil change in volume that causes because of variation of ambient temperature of oil-immersed type transformer.This method can be completely achieved all functions of former transformer oil conservator and improves, thereby has realized cancelling oil conservator on oil-immersed type transformer, avoids contacting of transformer oil and air.And in the transformer manufacturing, install, realized simple, practical, safety in the use.
Summary of the invention
For the complexity of the structure of the oil-immersed type transformer that overcomes existing band oil conservator and the inconvenience of use, the present utility model provides a kind of the bellows-type metallic elastic component is directly installed on the transformer body interior, utilize the swollen function that contracts of bellows-type metallic elastic component to realize automatic adjusting compensation to the transformer oil change in volume that causes because of variation of ambient temperature of oil-immersed type transformer, thereby cancellation transformer oil conservator, avoid contacting of transformer oil and air, realize the hermetically sealed of oil-immersed type transformer.
The technical scheme that its technical problem that solves the utility model adopts is, cancel the oil conservator of former traditional oil-immersed type transformer, according to the transformer BVO with the variation of ambient temperature variable quantity, on the oil tank of transformer top cover or the side one or several bellows-type metallic elastic components inwardly are installed, as transformer oil volume compensation device.When ambient temperature raise, the transformer BVO increased, and at this time the transformer internal pressure increases, and the bellows-type metallic elastic component will be compressed; When ambient temperature reduced, the transformer BVO reduced, and at this time the transformer internal pressure will be less than the pressure in the bellows-type metallic elastic component, and the bellows-type metallic elastic component will expand.So just realized automatic adjusting compensation to the transformer oil change in volume.On no oil conservator oil-immersed type transformer fuel tank top cover or by the rising of the tubular type on case lid seat, the device that shows the transformer oil level and collect gas is installed simultaneously, to be used for the monitoring and protecting transformer.In this technical scheme implementation process, other function of transformer and group parts application mode are constant, comprise device body, oil, shunting switch, sleeve pipe, radiator (cooler), pressure relief valve etc.
The beneficial effects of the utility model are, with the method that the bellows-type metallic elastic component is directly installed on the transformer body interior, utilize the swollen function that contracts of bellows-type metallic elastic component to realize automatic adjusting compensation to the transformer oil change in volume that causes because of variation of ambient temperature of oil-immersed type transformer, thereby be implemented in the transformer oil conservator that disappears on the oil-immersed type transformer, avoid contacting of transformer oil and air, realize the hermetically sealed of oil-immersed type transformer.And then realized simplification to transformer device structure, simple on making reduced material cost.Also realize the convenience on transformer installation and working service, and improved the security reliability of oil-immersed type transformer operation greatly.
