Definitions
- FIG. 4 shows a cross section through a dry-type transformer according to further embodiments
- FIG. 6 shows a cross section through a cooling system for a dry-type transformer according to embodiments
- a ring fan may have an annular housing as a stator, with a likewise annular rotor therein, are mounted on the blades, which are visible to the outside as in a conventional fan.
- the ring fan may be a bladeless fan in embodiments.
- a bladeless fan blows the air out of a ring without any direct involvement of rotating blades, or they are typically encapsulated in an extra housing. The air is sucked through an internally installed rotor in the base or on the side of the bladeless fan through holes located therein, and passed into a circumferential cavity of a ring. Subsequently, the air is accelerated through a slot, which is preferably provided on an inner side of the ring.
- the core may also have other orientations, such as horizontal to the earth's surface, so that the cooling air flow flows horizontally. In the following, however, it is assumed that technically usual vertical cores or legs are used.
- a fan may also be installed between the upper coil and the lower coil (in addition to the above-described variants, or individually).
- the above variants may be made individually for each leg, or a single fan with a ring may be used, which ring is not round but oblong and all three windings are on the covering three thighs.
- Embodiments have the following advantages over conventional ventilation techniques with conventional fans. Firstly, the initially described air guide plates and their holding device or connections can be completely eliminated. In addition, in embodiments, such as through a heat exchanger, cooled air can be passed directly to the fan through a pipe and then blown into the cooling channels. This avoids unnecessary heat exchange between the cooling air and the environment outside the windings. Therefore, the cooled air in the supply pipe to the ring or bladeless fan remains cool. Much of the accelerated by the fan air flows directly into and through the cooling channels in the windings, which is achieved at the same time with little or reduced structural complexity. In addition, especially the bladeless fans operate with a low noise level due to the absence of open, rotating blades as in a conventional fan or blower.
- a ring fan 30 arranged under the dry-type transformer 1 comprises a ring 32 and a fan 34 (see also FIG. 3).
- the blower 34 is configured to draw in ambient air (in embodiments, for example, the air may be supplied through a pipe) and to blow the air out of a slot 33 in the ring 32 in a directional manner along a longitudinal axis of the ring 32. In this case, a cooling air flow 35 is generated.
- the ring fan 30 is dimensioned and arranged so that it generates an annular cooling air flow 35 which fits geometrically to the dimensions of the cooling channel 25.
- FIG. 3 an exemplary, non-limiting example of a ring fan 30, 30a, 30b in the form of a blade-less fan is shown.
- the blown out of the slot 33 in the ring 32 cooling air flow 35 is symbolically represented by arrows.
- the supply of the cooling air to the blower 34 is shown.
- the cooling air flow is conducted or guided through a pipe or a line to the blower 34.
- FIG. 5 shows a dry-type transformer 1 according to exemplary embodiments, which represents a combination of the variants from FIGS. 1 and 2.
- the windings are divided on the core or leg, so that between the winding segments 70, 75, a further ring or bladeless fan 30 c is arranged. That is, the fan 30c is arranged between two winding segments 70, 75 arranged separately in the longitudinal direction of the core 10.
- the fan 30c is arranged between two winding segments 70, 75 arranged separately in the longitudinal direction of the core 10.
- the central or leaflet fan 30c may be used.
- the heated by the dry-type transformer 1 cooling air flow 35 is thus passed after passage through the cooling passage 25 of the dry-type transformer 1 in the heat exchanger 60 and cooled there.
- the cooled air stream is then sucked back through the blower 34 of the (or more) bladeless fan 30a by means of a tube 36.
- a closed cooling air circuit there is a closed cooling air circuit.
- Fig. 7 shows from below a dry-type transformer 1 with three legs 1 1, such as a three-phase transformer.
- a bladeless fan 30d is used, whose ring 32b is made elongated or elongated in order to cover all three winding bodies 14.
- one or more dedicated fans may also be provided for each leg 1 1 or winding body 14, as described for example with reference to FIGS. 1 and 5.
- the ringless fans 30, 30a, 30b, 30c described herein may be used according to embodiments for cooling all types of electric power devices 2, such as electric motors, generators, power semiconductor devices, etc. the power device 2 is equipped with a matching to the geometry of the cooling air flow opening 40, 42 of a cooling channel 25.
- the here elongated or elongated ring 32a of the bladeless fan can also take other forms than circular, such as elliptical, square or rectangular.
