Low-voltage current transformer box of transformer

The invention discloses a low-voltage current transformer box of a transformer. The box comprises a box cover and a box body, wherein the box cover is connected with the box body by a hinge; the interior of the box body is in a two-step shape from the top down; four wire outlet holes are formed in the front side surface of the box body at a first step; strip-type holes are formed in a length direction of the box body on the bottom surface of the box body at a second step; drainage grooves are formed on the two sides of the strip-type holes; a plurality of fixing clamps are arranged on the strip-type holes; drainage holes are formed in a side wall of the box body and corresponding to the drainage grooves; and a turnover angle of the box cover relative to the box body is 0-90 degrees. The box is convenient to mount, can prevent electricity larceny, and can be firmly and directly mounted on the transformer for use; wiring and routing of a current transformer and the transformer are facilitated; sleeves of the current transformer and the transformer have a safe distance; inspection of later personnel is facilitated; and the current transformer box can be effectively prevented from touching the transformer due to an excessive opening angle.
