Abstract
The utility model discloses a novel water-cooled transformer. The water-cooled transformer is characterized of comprising a cavity plate, wherein a water inlet tap is arranged on lower end of the cavity plate, a water outlet tap is installed on upper end of the cavity plate, the cavity plate is installed and surrounded in a nested manner between a primary coil and a second coil in the transformer body, current market situation is changed that the water-cooled transformer completes cooling through a water cycle in a hollow wire tube surrounded on an iron core, has a relatively small water capacity, and cools water on the coil only on one lateral resulting in weakening of water-cooled effect. According to the novel water-cooled transformer, the cavity plate is installed and surrounded in a nested manner between a primary coil and a second coil in the transformer body, the water capacity in the cooling device is increased, contact area of the cooling device and the primary coil and secondary coil in the transformer body is increased, water-cooled and heat dissipation in the cooling device are greatly enhanced, besides, the water-cooled transformer does not form a complete turn of coil, electric potential difference between the water inlet tap and the water outlet tap is 0 volt, the water inlet and outlet places have no electricity, safety of the water-cooled device in transformer operation is guaranteed.
Description
Technical field
The utility model relates to field transformer, relates in particular to a kind of water cooling transformer.
Background technology
Continuous automation development along with industrial technology, the application of electric equipment is more and more extensive, requirement to matching transformer wherein is just more and more higher, transformer is in running, because phenomenons such as iron loss, copper loss, the temperature of transformer can constantly rise very highly, therefore, the heat that the standby cooling system of matched transformer produces in the time of must effectively distributing the transformer operation, otherwise will greatly shorten and bring potential safety hazard the useful life of transformer.The most general type of cooling of transformer has three kinds of air-cooled, oil cooling and water-cooleds in the market, wherein, water-cooling pattern generally all be by on iron core around hollow spool in water circulation finish, the capacity of this kind water-cooling pattern water is less, and just the coil in a side carries out water-cooled, the contact-making surface of the coil of hollow spool and opposite side is little, can't reach preferably water-cooling effect.
The utility model content
The purpose of this utility model is to provide a kind of water cooling transformer for the deficiencies in the prior art, and its water-cooling effect is better, longer service life, and production technology is simpler.
For achieving the above object, technical solution of the present utility model is: a kind of water cooling transformer, comprise: transformer body, cooling device consists of, transformer body mainly is made of iron core, primary coil, secondary coil, and its structural principle is consistent with widely used traditional transformer main body on the market, it is characterized in that: described cooling device is made of the cavity plate, described cavity plate lower end is provided with water inlet tap, the upper end is provided with faucet, and the embedded encirclement of described cavity plate is installed between the primary coil and secondary coil in the transformer body.
Further, in order to reach better installation effect and radiating effect:
Described cooling device is made of two or more cavity plates.
The beneficial effects of the utility model are: solve water-cooled transformer in the market by on iron core around hollow spool in water circulation finish the water-cooling pattern of cooling, thereby the less present situation of just carrying out water-cooled reduction water-cooled effect at the coil of a side that reaches of the capacity of its water, by the cooling device in the middle of the utility model, the embedded encirclement of its cavity plate is installed between the primary coil and secondary coil in the transformer body, improve the capacity of water in the cooling device and increased the contact area of primary coil and secondary coil in cooling device and the transformer body, so, the water-cooling effect of cooling device just is greatly improved, its production technology is simpler simultaneously, longer service life, the more important thing is, this kind water cooling plant does not form a complete circle coil, it is 0 volt of the potential difference of water inlet tap on its cavity plate and faucet, the position that is to say water inlet tap and faucet is not charged, the fail safe of water cooling plant when having guaranteed the transformer operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the cavity plate in the water cooling plant in the utility model.
Among the figure: 1-transformer body, 101-iron core, 102-primary coil, 103-secondary coil, 2-water cooling plant, 201-cavity plate, 202-water inlet tap, 203-faucet.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Referring to accompanying drawing 1-2, a kind of water cooling transformer, comprise: transformer body, cooling device consists of, transformer body is mainly by iron core, primary coil, secondary coil consists of, and its structural principle is consistent with widely used traditional transformer main body on the market, of the present utility model being characterised in that: wherein cooling device is made of the cavity plate, improved the capacity of water in the cooling device, cavity plate lower end is provided with water inlet tap, the upper end is provided with faucet, the embedded encirclement of described cavity plate is installed between the primary coil and secondary coil in the transformer body, increased the contact area of primary coil and secondary coil in cooling device and the transformer body, so the heat in can extraordinary absorption transformer body, further, this kind water cooling plant does not form a complete circle coil, it is 0 volt of the potential difference of water inlet tap on its cavity plate and faucet, the position that is to say water inlet tap and faucet is not charged, the fail safe of water cooling plant when having guaranteed the transformer operation, this kind.During the transformer operation, by pressure so that the water inlet tap of cooling water through apparatus for supercooling cavity plate lower end enter, cooling water enters the heat of taking away on the transformer body behind the cooling device cavity plate and then discharges by the faucet of cavity plate upper end, because cold water density reaches more greatly the less principle of hot water density, when the water inlet tap of cavity plate lower end continues to import cold water, cooling water in the cavity plate becomes hot water owing to absorbed the heat of transformer body before, the hot water that density is larger will swim in above the less cooling water of density, so having absorbed the hot water of transformer body heat in the cavity plate can constantly discharge by the faucet of cavity plate upper end, thereby improved the radiating effect of transformer, further improve the radiating effect of cooling device such as need, also can increase the intake pressure of the water inlet tap of cavity plate, by accelerating water circuit quickening radiating effect in the cavity plate.
Further, in order to reach better installation effect and radiating effect, can be set to two or more cavity plates by cooling device, the arc that its cavity plate can be arranged to be close according to the shape of transformation body, its operation principle is consistent with above-mentioned principle.
