Abstract

The invention relates to the technical field of transformers, and discloses an intelligent dry-type distribution transformer, which includes a fixed base, fans are arranged inside both sides of the fixed base, and a dry-type transformer group is fixedly installed in the middle of the top of the fixed base , and the top of the dry-type transformer group is fixedly installed with a mounting bracket, and the two sides of the top of the mounting bracket are respectively provided with a control mechanism and a feedback mechanism, and the feedback mechanism includes a fixed sleeve. For the intelligent dry-type distribution transformer, for the setting of elastic airbags, conductive heating bulbs and current wires, when the dry-type transformer is in an overloaded state, the conductive heating bulbs will generate more heat, thereby forcing the elastic airbags to generate heat. Expansion until it ruptures due to excessive expansion, causing the conductive heating ball to fall off due to the loss of the support valve of the fixing cable, and then cut off the circuit connection between the two sets of current wires to realize the tripping action of the dry-type transformer.

Description

technical field

[0001] The invention relates to the technical field of transformers, in particular to an intelligent dry-type distribution transformer. Background technique

[0002] Dry-type transformer is a kind of transformer whose core and winding are not immersed in insulating oil. Therefore, compared with wet-type transformers, it has fireproof and explosion-proof characteristics, and has the advantages of strong short-circuit resistance, high operating efficiency and small size. It is widely used in lighting, machining and other fields.

[0003] Among them, dry-type transformers are divided into two forms: natural air cooling and forced air cooling. In the process of normal operation, natural air cooling is adopted, and the continuity of intermittent overload or emergency handling During overload operation, with the increase of its output power and the increase of heat, the simple air cooling measures can no longer meet its heat dissipation needs. Therefore, forced ai...
