Problems solved by technology
At present, the main body of the pressure equalizing shielding ring is bent and formed by L3 pure aluminum thin-walled tube and welded with the bracket. However, this material has low strength and high plasticity. The welding place between the tube and the bracket is often torn, and it is difficult to guarantee the weight of more than 200kg. The carrying requirements of the human test, so there is a great potential safety hazard

The invention discloses a grading and shielding ring for lines and power transmission. The grading and shielding ring comprises a ring body and a support connected with the ring body. The ring body and the support are both molded by the utilization of a 6063 aluminium alloy material. The ring body is approximately oval-shaped or circular. A 200kg people-bearing test is conducted on the grading and shielding ring for lines and power transmission, and test results all meet requirements. Thereby, potential safety hazard that welding positions of a grading and shielding ring for lines and power transmission are frequently torn and the bearing requirement of the 200kg people-bearing test cannot be guaranteed is solved.
Description
technical field [0001] The invention relates to the technical field of fittings for power transmission and transformation lines, in particular to a voltage equalizing shielding ring for lines and power transformation. Background technique [0002] Voltage equalizing shielding rings are widely used in high-voltage lines and substations for voltage equalizing and shielding string fittings to prevent corona and make radio interference meet the requirements. At present, the main body of the pressure equalizing shielding ring is bent and formed by L3 pure aluminum thin-walled tube and welded with the bracket. However, this material has low strength and high plasticity. The welding place between the tube and the bracket is often torn, and it is difficult to guarantee the weight of more than 200kg. The carrying requirements of the human test, so there is a great potential safety hazard Contents of the invention [0003] The technical problem to be solved by the present invention...
