[0002] Three-phase DC resistance balance is a crucial concept in power systems. It involves ensuring that the resistance values ​​of each phase in a three-phase circuit are as equal as possible to ensure circuit stability and efficiency. Especially in large-scale power systems, resistance imbalance in three-phase circuits can lead to uneven current distribution, potentially causing equipment damage, system instability, and even fire hazards.

[0003] Achieving balanced three-phase DC resistance requires specialized designs and structures to ensure precise control and adjustment of the resistance value of each phase. In a three-phase DC system, resistance imbalance can lead to uneven current distribution, impacting system stability and efficiency. Traditional structural designs may not effectively address this issue. Utility Model Content

Traditional structural designs may not be able to effectively solve this problem.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] base plate;

[0008] A baffle plate, the baffle plate including an A-phase winding, a B-phase winding, and a C-phase winding, the baffle plate, the A-phase winding, the B-phase winding, and the C-phase winding are all connected to the upper end of the bottom plate;

[0009] The sealing plate is fixedly connected to the upper end of the bottom plate, and the sealing plate matches the blocking plate.

[0010] As a preferred solution of the present invention, the upper ends of the blocking plate, the A-phase winding, the B-phase winding and the C-phase winding are fixedly connected to a top plate, and the upper end of the top plate is fixedly connected to an outgoing conductor.

[0016] 1. In this solution, by connecting the A, B, and C phase windings to the barrier plate at the top of the base plate and using a sealing plate, the resistance balance between the three phases can be effectively maintained. This is crucial for the stable operation of three-phase DC power systems, as unbalanced resistance will lead to uneven current distribution, which in turn affects the efficiency and life of the equipment.
