The utility model, for solving the shortcoming of the installation and maintenance inconvenience of the above-mentioned existing voltage transformer existence of mentioning, provides a kind of voltage transformer of integral housing.
Concrete, the utility model provides a kind of voltage transformer, the base that it comprises housing and is arranged on described housing bottom, described housing top is provided with fuse, described enclosure interior is provided with iron core, winding and secondary winding, described secondary winding connects a described winding, described iron core connects described secondary winding, a described winding is connected with outlet terminal one time by an inserts, and described enclosure interior is also provided with an outlet terminal described in secondary outlet terminal and is arranged on described fuse.
Preferably, described outside is provided with the nameplate of mark model, is provided with for fixing lead sealing screw on described nameplate.
Preferably, the integral totally enclosed housing that described housing is poured with epoxy resin.
Preferably, described housing is shaped as square.
Preferably, on described housing, be provided with for fixing set bolt.
Preferably, described fuse stretches out the outside of described housing, and the quantity of described fuse is 3.
Preferably, the medianly zygomorphic groove of being convenient to control that is provided with of described housing.
The utility model also can require to do charged display device according to user in use, and it is little to the utlity model has volume, and floor space is few, easy for installation and be convenient to safeguard, stable work in work, and production efficiency is high and can be used for the advantages such as outdoor.
