The operation principle of the technical program is, the current transformer being enclosed with insulator is arranged in body of wall, by adpting flange, conducting rod is fixed on current transformer both sides, therefore when changing wall bushing of installation, without being arranged on whole for wall bushing in body of wall, but first in body of wall, fixed packet is wrapped with the current transformer of insulator, conducting rod is installed in current transformer both sides again, substep assembles this wall bushing, improve the installation effectiveness of wall bushing, reduce task difficulty, owing to only conducting rod is exposed to external environment condition, easily damage, therefore oversheath is set outside conducting rod, when conducting rod being keeped in repair and changing, directly by adpting flange, conducting rod can be disassembled, keep in repair and change, convenient and swift.
In order to the present invention is better achieved, further, described oversheath is epoxy resin glass set.
In order to the present invention is better achieved, further, oversheath is extended in one end of described conducting rod, and is provided with binding post.
In order to the present invention is better achieved, further, described conducting rod is copper conducting rod.
In order to the present invention is better achieved, further, it is additionally provided with silicon rubber umbrella outside described full skirt.
In order to the present invention is better achieved, further, described mounting plate is annular, it is provided with six ring-shaped distributed fixing bolts and fixes with insulator.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is by improving the structure of wall bushing, by tradition overall cuttage, wall bushing is installed, by assembly type, wall bushing is installed till now, greatly reduce the installation difficulty of wall bushing, improve installation effectiveness, decrease and the lifting appliance that wall bushing needs to use is installed, in a disguised form decrease the installation cost of wall bushing；
(2) present invention structure by reform pattern wall bushing, on the premise of ensure that security, facilitate the later stage that mounted wall bushing carries out replacing and the maintenance of part, and without being changed by whole wall bushing, reduce the use cost of wall bushing；
(3) present invention carries out the transmission of electric current by the current transformer being placed in body of wall, improves the controlling of the conveying of electric power, and overall structure is simple, convenient and practical, suitable wide popularization and application.
