The invention provides an integrated detection device for electrical tests of power transformation equipment. According to the integrated detection device, multiple instruments are integrated into a tank body, so that the intensive detection is realized by virtue of the multiple instruments, each instrument does not need to be carried, and the use is relatively convenient; circuits are integrallyarranged in a channel in a box body, so that the circuits are relatively clean, tidy and safe, and the integral appearance is relatively good; and by arranging a routing pipe, the circuits of each instrument can be inserted into a pipe body of the routing pipe through a wire insertion slot and can be inserted into the pipe body of the routing pipe through a slot hole in the top, the slot hole is zigzag, and the circuits are commonly straight lines, so that the circuits are difficult to be separated from the routing pipe, the mounting of the whole circuit is very convenient, and the working efficiency is greatly improved. The integrated detection device is simple in structure, convenient to carry and store and compact in mounting structure and has very good market prospects.
