Summary:The invention discloses a blast protection and fire protection oiled paper capacitor-type transformer casing pipe, which comprises a wiring terminal, a metal expander, an upper insulator, a mounting flange, a flange cylinder, a lower insulator, a base, a conducting bar and a capacitor core, wherein the lower insulator is a glass steel cylinder, the mounting flange is fixed together with the flange cylinder, the flange cylinder is cast with the lower insulator into a whole, the base is arranged on the lower insulator in a cementing manner, the capacitor core serving as a main insulator is fixedly and hermitically arranged in the upper insulator, the flange cylinder, the lower insulator and the base through strong springs, and the metal expander used for enabling the interior of the casing pipe to be always kept in micro-positive pressure is arranged on the top of the upper insulator. When the interior of the casing pipe is subjected to pressurizing due to faults, the metal expander on the head part firstly act
