Abstract

The invention relates to a special insulated protection shell of a mutual inductor. The shell consists of a front shell and a back shell, wherein a front bus inlet and a front bus outlet are separately arranged on the left and right sides of the top or bottom of the front shell, a front bus inlet and a back bus outlet are separately arranged on the left and right sides of the top or bottom of the back shell; a front secondary line outlet and a front secondary line inlet are separately arranged on the left and right sides of the lower part of the front shell, a back secondary line outlet and a back secondary line inlet are separately arranged on the left and right sides of the lower part of the back shell; the vertical edges of the left and right sides of the front shell and the back shell are correspondingly provided with a plurality of zygomorphic stop dogs and slots respectively; and the stop dogs are spliced with the slots, and the stop dogs and slots are integrated with the front shell and the back shell into a whole. The shell in the invention has the advantages of scientific, reasonable and creative design, compact integral structure, low cost, stable and reliable performance, higher practicability and better prospects. The special insulated protection shell is suitable for industrial and mining enterprises, in particular to steel mills and power supply departments.

Description

Technical field [0001] The invention relates to a protective casing, in particular to a special insulating protective casing for a transformer with beautiful appearance, good electrical performance, and convenient manufacture and installation. Background technique [0002] At present, most of the current transformers of 35kV and below produced at home and abroad use epoxy resin casting products. The use of epoxy resin casting type greatly reduces maintenance costs and procedures compared with the previous oil-immersed type. However, there are many casting molds involved in epoxy resin casting products, and the appearance of the cast body is not very ideal, such as large tire gaps and scratches on the surface of the casting body. This requires a lot of manual repair, but the final effect is not as good as the unrepaired place. At the same time, it also means wasting a lot of manpower and virtually increasing the production cost. And the appearance is not beautiful. Summary of ...
