Abstract

The invention relates to a voltage grading device for a + / -1,100-kV indoors-arranged dry-type air-core smoothing reactor. The voltage grading device comprises a reactor body (3), a lightning rod (14) and a supporting system (10), and seven circles of segmented grading rings are arranged on the reactor body (3) and the supporting system (10); and multiple layers of ring-type grading rings are arranged on the lightning rod (14). According to the voltage grading device, by adopting the configuration structure of multiple circles of the segmented grading rings and multiple ring-type grading rings, configuration is reasonable and passes simulation calculation and experiment verification, the electric field distribution uniformity can be achieved maximally, the surface electric field intensity of the + / -1,100-kV indoors-arranged dry-type air-core smoothing reactor is effectively reduced, the corona and the electric erosion loss which are generated at the end of the + / -1,100-kV indoors-arranged dry-type air-core smoothing reactor and the high-voltage sides of post insulators are effectively inhibited, the corona discharging problem generated at the tip of a metal end frame of the + / -1,100-kV indoors-arranged dry-type air-core smoothing reactor after the system voltage is increased is solved, and then the environment problems such as audible noise and radio interference are solved.

Description

technical field [0001] The invention relates to the technical field of transformer protection equipment, in particular to a ±1100kV indoor dry-type air-core smoothing reactor voltage equalization device. Background technique [0002] The development of large-capacity, high-efficiency, and long-distance advanced transmission technologies such as UHV is a clear requirement put forward by the national "13th Five-Year Plan". The development of UHV is the top priority of the "13th Five-Year Plan" power grid development, and the DC transmission project is an important part of it. At the same time, the "13th Five-Year Plan" is a critical period for the innovation and development of DC transmission technology. Stepping up to a new level and further improving the technical level of DC transmission, the State Grid Corporation will improve the advanced nature, adaptability and economy of DC projects through technological innovations such as ±1100kV, multi-terminal DC and double-circuit ...
