The invention discloses a transformer capable of preventing electromagnetic interference. The transformer comprises a transformer body; a protective cover is arranged outside the transformer body; a plurality of grounding holes are formed in the middle of the bottom of the protective cover; the grounding holes are uniformly distributed at equal intervals; side grooves are formed in the two sides of the two ends of the upper end of the protective cover; first electric telescopic rods are fixedly connected into the side grooves; inner grooves are formed in the two sides of the protective cover;and foaming metal plates are arranged in the inner grooves. The beneficial effects are that: the grounding holes are arranged, and the grounding holes in the bottom of the protective cover enable grounding wires of the transformer body to be grounded to introduce electromagnetic interference into the ground from the grounding holes; the plurality of grounding holes can enable the rest grounding wires to still be able to introduce the electromagnetic interference to the ground when one grounding wire is damaged; and by arranging a sliding groove, when the transformer body is placed on the fixing plate in the protective cover, a sliding block at the bottom of the transformer body can move in the sliding groove, and the transformer can be pushed into the protective cover by pushing the transformer body to one side of the interior of the protective cover, and great convenience is achieved.
Description
technical field [0001] The invention relates to a transformer, in particular to a transformer capable of preventing electromagnetic interference, and belongs to the technical field of electric equipment. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It can realize voltage conversion, current conversion, and impedance conversion. It is an indispensable electrical equipment in the process of power transmission. [0003] In the prior art, the transformer is exposed to the outside, and there are many external electromagnetic interference sources, not only natural noise interference, but also various artificial devices will also generate a large amount of electromagnetic interference. The transformer is often subjected to electromagnetic interference during use, and strong Electromagnetic interference may increase transformer loss and reduce service life.
