The invention belongs to the technical field of power grid equipment, and discloses a low-voltage line three-phase imbalance monitoring device and an installation tool thereof.An acquisition unit is placed in a bracket, the other end of an upper cover is opened and clamped and fixed to an upper cover fixing piece, so that the upper cover is kept in an open state, and then a snap spring is tilted and clamped and fixed by a snap spring fixing assembly; the clamp spring is in an open state, the grounding rod is connected to the bottom of the body, the acquisition unit is lifted, a to-be-tested wire is placed in the semicircular groove 111 of the lower shell, and in the upward lifting process of the acquisition unit, the to-be-tested wire applies certain pressure to the acquisition unit, so that the acquisition unit is separated from the installation tool. The clamp spring is clamped on the to-be-detected wire, the upper cover covers the lower shell to form a magnetic field, current collection can be carried out
