Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer which is convenient for controlling dynamic loads. Background Art

[0002] A dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil. It is suitable for intermittent overload operation or emergency overload operation. Due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operating state and should not be subjected to long-term continuous overload operation. It is widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places.

[0003] The prior art discloses a dry-type transformer that is easy to control dynamic loads, with a publication number of CN216773030U. The dry-type transformer that is easy to control dynamic loads includes a transformer housing, a coil is provided inside the transformer housing, a resistor is electrically connected to the bottom of the coil, a fixed ring is provided inside the transformer housing, and an external connector is provided on the outer wall of the fixed ring. The dry-type transformer that is easy to control dynamic loads, by rotating the screw rod, the interval between the upper magnetic core and the lower magnetic core is reduced, and the electromagnetic vibration is further reduced, thereby achieving the effect of avoiding excessive intervals between the magnetic cores and reducing losses. By rotating the rotating disk, the direction of the connector can also be rotated, further changing the point where the connector is connected to the inner connector, and at this time, the external connector connected to the connector will also change, further changing the resistance value of the resistor connected to the connector, and at this time, the output voltage will change, thereby achieving the effect of being easy to control dynamic loads and having strong applicability.

[0004] The above-mentioned dry-type transformer that is easy to control dynamic loads uses a screw and an upper magnetic core and a lower magnetic core in combination. Rotating the screw reduces the interval between the upper magnetic core and the lower magnetic core, further reducing the electromagnetic vibration, thereby achieving the effect of avoiding excessive intervals between the magnetic cores and reducing losses. However, the above-mentioned dry-type transformer generates a large amount of heat during operation, so the thermal characteristics and cooling design of the winding must be considered. The above-mentioned device does not have a reasonable winding structure and cooling system, cannot effectively reduce the temperature rise, cannot improve the power density and reliability of the transformer, and has poor practicality.
