Abstract

The invention provides a coil shielding device and a transformer with the same. The coil shielding device comprises an annular shielding box and at least one winding of the transformer coil, wherein the internal of the annular shielding box is provided with at least one winding of the transformer coil; the iron core of the transformer can be sleeved with the annular shielding box; and at least one place of the annular shielding box is disconnected to form a first end and a second end to prevent the annular shielding box from forming an electric loop. Through the coil shielding device, the windings of the coils of the transformer can be shielded to solve the potential safety hazards of the transformer and to strengthen the protection on personal safety of power supply systems and the protection on power supply equipment.

Description

technical field [0001] The invention relates to a coil shielding technology, in particular to a coil shielding device and a transformer with the coil shielding device. Background technique [0002] In the traditional transformer manufacturing process, the winding coil itself does not have a shielding device. When other coils fail or are abnormal, when high voltage directly enters the winding, it will bring safety hazards to personal or secondary power supply. However, the commonly used transformer coil shielding structure is realized by installing a metal shielding layer isolation between the concentric primary and secondary windings. With the development of transformer technology, the power supply of the secondary power supply system is required to be directly taken from a part of the secondary winding of the transformer, while the other winding or other windings are in a high voltage state, which has certain potential safety hazards. In this case, how to shield a single o...
