9. A novel three-phase unbalanced compensation device according to claim 1, characterized in that: A rain shield (12) is fixedly connected to the top of the outer frame (101), and the rain shield (12) is an inclined structure.

10. An application method of a novel three-phase unbalanced compensation device, according to the novel three-phase unbalanced compensation device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: After the device is hoisted to the required height, the personnel hold the knob (6) and rotate the pressure ring (204) and the first screw (203) to loosen them. At this time, the sliding arms (202) on both sides are slid to one side of the main clamping plate (206) in cooperation with the U-shaped first limiting hole (205); the two main clamping plates (206) are respectively attached to the outer side of the electric pole of the distribution box, and then the auxiliary clamping plate (211) and the main clamping plate (206) are installed, and then the first screw (203) is rotated clockwise to fix the length of the sliding arms (202) on both sides; Step 2: Fine-tune; The third screw rod (303) is rotated counterclockwise, the outer side of the outer frame (101) is held, and the outer frame (101) is finely adjusted in horizontal position by cooperating with the U-shaped second limiting hole (302); after the outer frame (101) is finely adjusted to a desired horizontal position, the outer frame (101) is connected to the distribution box; Step 3: After the outer frame (101) and the distribution box are connected and installed, rotate counterclockwise and remove the third screw (303); at the same time, remove the auxiliary clamping plate (211); remove the external displacement structure (2) and the fine-tuning structure (3); Step 4: The lines are connected, and the data concentrator (102), the optical network transmitter (104), the capacitor (105), the automatic leveling commutator (106) and the switching unit (107) are turned on respectively to start monitoring and adjusting the three-phase power imbalance compensation.
