Extra-high voltage (EHV) DC transmission project capacitor noise reduction structure

The invention discloses an extra-high voltage (EHV) DC transmission project capacitor noise reduction structure, and belongs to the extra-high voltage (EHV) DC transmission project capacitor unit noise reduction technical field; the extra-high voltage (EHV) DC transmission project capacitor noise reduction structure comprises a capacitor unit; a noise reduction module is arranged in the capacitor unit, and press-mounted with the capacitor core with the compaction coefficient of 0.8; the length and width of the noise reduction module are well matched with the capacitor unit internal sizes; the noise reduction module is filled with air, 10-70mm in height, and made of stainless steel or epoxy material. The noise reduction module is arranged in the capacitor unit, so the capacitor unit performance can be less affected; the extra-high voltage (EHV) DC transmission project capacitor noise reduction structure uses the sound insulation principle to effectively solve the capacitor unit noise problems. 本发明公开种特高压直流输电工程用
