Abstract
The utility model relates to a kind of dry-type transformer replacing blower fan apparatus that do not have a power failure, comprise dry-type transformer, be arranged on the centrifugal blower below dry-type transformer, this centrifugal blower is connected with air port through airduct, air port is connected to the bottom of dry-type transformer, blows cold wind to cool the winding construction of dry-type transformer to dry-type transformer.Compared with prior art, the utility model damages due to the cooling blower of transformer, replacing needs to have a power failure, cause the interruption of normal power supply, along with the quickening of rhythm of production requires also to improve to power supply reliability thereupon, in order to reduce the impact had a power failure on producing as far as possible, this device can change transformer cooling fan when not having a power failure, and improves the reliability of dry-type transformer.
Description
Technical field
The present invention relates to a kind of blower fan apparatus, especially relate to a kind of dry-type transformer replacing blower fan apparatus that do not have a power failure.
Background technology
At present, the winding lower end that the blower fan of dry-type transformer is all directly installed on transformer is come for Transformer Winding cooling.When after blower fan damages more ventilating fan time, because blower fan is comparatively near so transformer must be stopped transport and could be changed apart from high pressure winding.Cause the interruption of normal power supply.
Chinese patent CN102723168A discloses a kind of dry-type transformer, comprise transformer body and be arranged on the some blower fans bottom transformer body, dry-type transformer also comprises fixed mount, fixed mount is arranged on the bottom of transformer body by hanging screw rod, some blower fans are dismountable to be arranged on fixed mount, although this kind of transformer can adjust the installation site of blower fan, provide maximum air quantity to Transformer Winding, still cannot solve the problem of above-mentioned power failure.
Summary of the invention
Object of the present invention is exactly provide a kind of dry-type transformer that improve the reliability of dry-type transformer not have a power failure replacing blower fan apparatus to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of dry-type transformer replacing blower fan apparatus that do not have a power failure, comprise dry-type transformer, be arranged on the centrifugal blower on dry-type transformer side, this centrifugal blower is connected with air port through airduct, described air port is connected to the bottom of dry-type transformer, blows cold wind to cool the winding construction of dry-type transformer to dry-type transformer.
Described centrifugal blower is provided with two, is symmetricly set on the both sides of dry-type transformer.
Described centrifugal blower is double-suction centrifugal fan.
Dry-type transformer is made up of multiple winding, and the bottom of each winding is all connected with air port
Preferably, described winding is provided with three.
Compared with prior art, the present invention damages due to the cooling blower of transformer, replacing needs to have a power failure, cause the interruption of normal power supply, along with the quickening of rhythm of production requires also to improve to power supply reliability thereupon, in order to reduce the impact had a power failure on producing as far as possible, this device can change transformer cooling fan when not having a power failure, and improves the power supply reliability of dry-type transformer.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
In figure, 1 be centrifugal blower, 2 be airduct, 3 be dry-type transformer, 4 for air port.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of dry-type transformer replacing blower fan apparatus that do not have a power failure, its structure as shown in Figure 1-2, comprise dry-type transformer 3, be arranged on the centrifugal blower 1 of dry-type transformer 3 both sides, this centrifugal blower 1 is connected with air port 4 through airduct 2, air port 4 is connected to the bottom of dry-type transformer 3, cold wind is blowed to cool the winding of dry-type transformer 3 to dry-type transformer 3, dry-type transformer 3 can be provided with multiple winding, winding is provided with three altogether in the present embodiment, the below of each winding is connected with air port 4, and each air port is all connected with centrifugal blower by airduct.Centrifugal blower 1 is double-suction centrifugal fan, is provided with two altogether, is symmetricly set on the both sides of dry-type transformer 3.
The present invention damages due to the cooling blower of transformer, replacing needs to have a power failure, cause the interruption of normal power supply, along with the quickening of rhythm of production requires also to improve to power supply reliability thereupon, in order to reduce the impact had a power failure on producing as far as possible, this device can change transformer cooling fan when not having a power failure, and improves the power supply reliability of dry-type transformer.
