摘要:
爲了對隔離開關動作産生瞬態輻射場的波形特征進行研究,文中對330 kV開關站內隔離開關動作所産生的VFTO輻射電場進行了測量與分析。研制了一套能夠適應複雜電磁環境應用的電場測量系統;開展了針對不同線側隔離開關操作所産生VFTO輻射電場的測量工作;從時域和頻域對其測試結果進行了研究分析。研究結果顯示:距開關3 m處,隔離開關動作産生的輻射電場強度幅值可達4.65 kV/m;輻射電場頻譜分布在200 MHz以下,且在某幾個特征頻率上集中分布;母線側及出線側隔離開關操作産生的VFTO輻射場具有不同的頻譜分布;隔離開關的分閘及合閘操作産生的VFTO輻射場具有不同的頻譜分布。
Abstract:
In order to study the waveform characteristics of the transient radiation field produced by the operation of disconnector, the radiated electric field generated by the operation of disconnector in the 330 kV Switching station is measured and analyzed. First, an electric field measurement system based on optical fiber is developed. Then very fast transient overvoltage(VFTO)radiation field generated by operation of disconnector on the different side is measured in the switch station. The measurement results are analyzed both in time domain and frequency domain. The results show that amplitude of the electric field generated by the operation of disconnector at 3 m away from the disconnector can reach 4.65 kV/m. The radiated electric field has a spectrum below 200 MHz, especially in some characteristic frequencies. The VFTO radiation field generated by the operation of disconnector on the busbar side and outgoing line side has different spectrum distribution. The VFTO radiation field generated by the opening and closing operation of disconnector has different spectrum distribution.
