Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to an outdoor dry-type transformer. Background Art

[0002] Dry-type transformer is one of the transformers. The cooling methods are divided into natural air cooling and forced air cooling. When the transformer is naturally cooled, it can operate continuously at rated capacity for a long time. When the transformer is forced to cool, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation. Because the load loss and impedance voltage increase greatly when overloaded, it is in a non-economical operation state, so it should not be in long-term continuous overload operation.

[0003] In the current prior art, the bottom of the dry-type transformer is fixedly connected with a base. When it is installed outdoors, the base of the dry-type transformer is attached to the support surface and then locked and fixed using a locking member. However, it is inconvenient to adjust the installation height of the dry-type transformer according to the needs of use, which affects the use effect. Therefore, it is necessary to design an outdoor dry-type transformer to solve the above problems. Utility Model Content
