Abstract
The utility model discloses a water-cooled transformer which can effectively overcome the ionizing phenomenon when being used. The cross section of each conduit of the water-cooled transformer is round, each water faucet which is connected with circulating cooling water is directly led out by the round port of the conduit, so that the welded part of the conduit and the water faucet, and the welded part of the conduit and the lug of a connecting copper bar are staggered, and thereby, the ionizing corrosion phenomenon which is caused during use can be effectively avoided. The water-cooled transformer is used in the field of transformers.
Description
Technical field
The utility model relates to a kind of water-cooled transformer.
Background technology
Transformer because of the existence of iron loss, eddy current, magnetic hysteresis and copper loss, can cause that the transformer temperature raises in running, therefore, transformer all is equipped with the heat that produces when cooling system just can make transformer distribute work smoothly.Forms such as that the cooling of transformer has is air-cooled, oil cooling and water-cooled.Water cooled transformer will make open-core type as the coil of secondary winding, allow cooling water circulate in this hollow spool and form the cooling system of water-cooled transformer.The cross section of the hollow spool of present water-cooled transformer mostly is square, its water nozzle that connects recirculated water goes out from the outside of copper busbar, near excessively with the welding position of square spool and copper busbar line ear, cause in use at water-cooled transformer, because continuous boiler water circulation was cold really when big electric current passed through, water nozzle and spool welding position produce the ionization corrosion and cause seepage.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of water-cooled transformer that effectively overcomes the ionization phenomena in the use is provided.
The technical scheme that the utility model adopted is: the cross section of the spool of water-cooled transformer described in the utility model is for circular, and the water nozzle of connection cooling circulating water is directly picked out by the port of described spool.
The beneficial effects of the utility model are: the cross section of the spool of water-cooled transformer described in the utility model is for circular, the water nozzle of connection cooling circulating water is directly picked out by the port of the described spool of circle, make water nozzle stagger mutually, thereby avoid producing in the use ionization corrosion phenomenon effectively with the welding position of spool and the welding position of spool and copper busbar line ear.
Description of drawings
Fig. 1 is the structural representation of the utility model water-cooled transformer;
Fig. 2 is the side-looking structural representation of the utility model water-cooled transformer.
Embodiment
As shown in Figure 1 and Figure 2, the cross section of the spool 1 of water-cooled transformer described in the utility model is circular, and the water nozzle 2 of connection cooling circulating water is directly picked out by spool 1 port of circle.
Such structure makes water nozzle 2 stagger mutually with the welding position A of spool 1 and the welding position B of spool 1 and copper busbar 3 line ears, thereby avoids producing in the use ionization corrosion phenomenon effectively.
Claims (1)
1, a kind of water-cooled transformer is characterized in that: the cross section of the spool of described water-cooled transformer is for circular, and the water nozzle of connection cooling circulating water is directly picked out by the port of described spool.
