The invention provides a DC field polar line outlet structure based on an integrated framework. The structure comprises the integrated framework and polar line outgoing lines (15), the integrated framework comprises framework columns (1) and a framework beam (4), two opposite ends of the framework beam (4) and the separate framework columns (1) form fixed connected structures respectively, and a Pi-shaped structure is formed between the framework columns (1) and the framework beam (4); the framework columns (1) are fixedly connected with outlet hanging rings (130), the framework beam (4) is connected with a high voltage capacitor (16), and the outlet hanging rings (130) are connected with the polar line outgoing lines (15). The DC field stage line outlet structure based on the integrated framework has the advantages that an independent high-voltage polar line outlet framework necessary in a traditional outlet structure can be eliminated, occupied site area for ensuring air clear distance is effectively reduced, the reliability and safety of DC field polar line outlet are improved, steel amount required for the construction of a converter station DC field is reduced, and investmentcost is saved.
