An on-line monitoring device for grounding resistance
This utility model discloses an online grounding resistance monitoring device, including a fixed frame. A fixed housing is mounted on top of the fixed frame, and water storage boxes are fixedly connected to both the left and right sides of the inner wall of the fixed housing. A rotating rod is rotatably connected to the top of the inner wall of each water storage box. In this utility model, heat generated by the monitoring device is absorbed and discharged through heat dissipation fins on the outer wall of the protective housing. Then, appropriate water is added inside the water storage housing, and the water is drained into a water tank inside the water storage box through a second drain pipe inside the housing. The filling of the water tank causes a movable ring plate to rotate, which in turn causes a support rod to rotate, which in turn causes a rotating rod to rotate. The rotating rod then causes a rotating shaft to rotate, which in turn causes a cooling fan on the outer wall to rotate, dissipating the heat absorbed by the heat dissipation fins.
