High-tension coil, is provided with the interlayer that insulating materials is made, described transformer between the low-voltage coil and the high-tension coil
Body is using poured with epoxy resin into an integrally-built pour mass, and the transformer body upper end and side set one respectively
Secondary embedding female and secondary embedding mother, it is described once it is embedding it is female be connected with the high-tension coil, it is described secondary embedding female to connect with the low-voltage coil
Connect, the mounting base, which is fixedly connected on the transformer body bottom, the mounting base, is provided with the embedding mother of installation；It is described
Transformer body upper end periphery is provided with the full skirt of turriform arrangement.
Preferably, described secondary embedding mother is placed in the secondary capping that transparent material is made, and described transparent material is to have
Machine glass.
Preferably, the secondary capping is installed on the mounting base by screw rod.
Preferably, mounting base upper surface front and back end is respectively arranged with proficiency handle.
Preferably, one is respectively arranged with the corner of the mounting base upper surface is used to install fixed fixing hole.
Implement the utility model embodiment, have the advantages that：
The utility model is formed using epoxide resin vacuum cast, is eliminated the shortcoming of oil leak and oil deterioration, is realized oil-free
Change, eliminate the preventive trial of annual oil immersion product, saved substantial amounts of manpower and materials；Meet thermal shock when open air is used
Greatly, shake that big, speed is fast, blast it is big the need for, be resistant to the environment bars such as wind-engaging, sand, rain, snow, mist, dew, light (ultraviolet), warm change
Part, safety and reliability is also more tolerant of and directly impacted out of doors by the overvoltage of thunder and lightning, Operation switch etc.；The utility model
With it is safer, reliable, accurate, stable the characteristics of；Suitable for the electric railway electricity of frequency 50Hz/60Hz, 25kV/27.5kV
Online work isolation is electrically and relay control is used.
