Abstract

The invention provides a power grading ring, which comprises a titanium alloy upper ring body and a titanium alloy lower ring body which are equal in diameter, wherein a nickel alloy intermediate ring body is arranged between the upper ring body and the lower ring body; the upper ring body, the lower ring body and the intermediate ring body are parallel and are arranged coaxially; the adjacent ring bodies are connected through connectors arranged on the circumferences of the ring bodies; and the diameters of the upper ring body and the lower ring body are greater than that of the intermediate ring body. Tight combination of the ring bodies and an insulating material can be effectively ensured through titanium alloy electrogalvanizing; meanwhile, the ring bodies also have better weather resistance when an insulator falls off due to environmental concerns; and the titanium alloy intermediate ring body is arranged in the middle of the grading ring and has a better voltage-stabilized transmission effect.

Description

technical field [0001] The invention relates to a voltage equalizing ring for electric power, belonging to the technical field of electric power accessories. Background technique [0002] At present, the common pressure equalizing ring is an open ring body. During installation and replacement, the open ring body is prone to discharge and has poor stability. In some occasions where additional installation or replacement is required, installation and maintenance are inconvenient and the cost increases; and If a small part of the pressure equalizing ring has some adverse phenomena such as a little aging, it needs to be replaced as a whole. Contents of the invention [0003] A new type of pressure equalizing ring for electric power, including an equal-diameter titanium alloy upper ring body and a titanium alloy lower ring body, a nickel alloy intermediate ring body is arranged between the upper ring body and the lower ring body, and the upper ring body, the lower ring body and...
