Description

Transformer with high safety Technical Field The utility model relates to the technical field of transformers, in particular to a transformer with high safety. Background Dry transformers are widely used in places such as local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and the like, and simply said dry transformers refer to transformers in which the iron cores and windings are not immersed in insulating oil. In the dry-type transformer in the prior art, when the coils on a plurality of groups of connecting leads are assembled with a plurality of groups of connecting ends on an iron core barrel respectively, the coils are pressed and fixed together by adopting a bolt screwing mode, but the mode has the defects that the head of the bolt is directly exposed, the situation of false touch is easy to occur during use, and potential safety hazards exist. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the transformer with high safety, and the insulating protection cover is arranged at the head part of the bolt, so that the bolt is prevented from being directly exposed when a connecting wire is connected with the wiring terminal through the bolt, safety accidents caused by direct contact between foreign objects and the head part of the bolt can be avoided, and the safety performance of the transformer is improved. The aim of the utility model is realized by the following technical scheme: The utility model provides a transformer with high security, includes the transformer body, connecting wire pass through the bolt with the wiring end of transformer body is connected, the head of bolt is equipped with detachable insulating protection cover, the head of bolt is hidden in insulating protection cover. Further, the insulation protection cover comprises a semi-cylindrical protection body, and a head groove for accommodating the head of the bolt and a rod body groove for allowing the rod body of the bolt to pass through are sequentially formed in the plane of the protection body from top to bottom; the two end surfaces of the protection body are respectively provided with a first baffle and a second baffle which are protruded out of the plane of the protection body. Further, the head groove and the rod body groove are arc-shaped structures. Further, one end of the head groove and one end of the rod body groove penetrate through the arc-shaped surface of the protection body. Further, the second baffle is a circular plate, and a cross groove is formed in the second baffle. Further, the insulating protective cover is made of plastic or rubber. Further, one end of the first baffle plate and one end of the second baffle plate, which are far away from the head groove, are connected through reinforcing ribs. Further, the protection body, the first baffle, the second baffle and the reinforcing ribs are of an integrated structure. The beneficial effects of the utility model are as follows: according to the utility model, the insulating protective cover is arranged at the head part of the bolt, so that the bolt is prevented from being directly exposed when the connecting lead is connected with the wiring terminal through the bolt, safety accidents caused by direct contact between foreign objects and the head part of the bolt can be avoided, and the safety performance of the transformer is improved.
