Abstract
This application relates to a transformer and power equipment. The transformer includes: a low-voltage coil; a high-voltage coil; a magnetic core, where at least a part of the magnetic core is penetrated through the low-voltage coil and the high-voltage coil; an insulation member with a ground plane disposed on an outer surface of the insulation member; and a voltage uniform layer. The insulation member is wrapped around the high-voltage coil, so that the high-voltage coil is insulated from the low-voltage coil and the magnetic core, heat dissipation of the high-voltage coil, low-voltage coil and the magnetic core can be facilitated, and a service life of the transformer can be prolonged. A structure of the transformer is simplified, so that installation and maintenance of the low-voltage coil and the magnetic core can be facilitated, and processing and maintenance costs of the transformer can be reduced.
