Based on the special load of the contactless system , this paper analyses and contrasts the principle and feature of the series and parallel resonance circuit . design the high frequency full - bridge series resonance converter and make the main circuit apply to the contactless electrical power deliver system and analyses the process of the main circuit in detail 根據無接觸電能傳輸系統特殊的負載特性,詳細分析并對比了并聯和串聯逆變器的工作原理及電路特點,設計出應用于無接觸系統中的高頻全橋串聯諧振逆變器的拓撲結構,進而設計并制作了系統的主電路,詳細的分析了主電路的工作過程。

The way of taking one nth out of capacitor ' s the first harmonic capacitive reactance as its nth harmonic impedance is verified whit the data from tang7c . according to the approximately estimating method , the first harmonic impedance of 220kv system is calculated . on the basis of the models , this paper gives the harmonic equivalent circuit of substation and gives the b ( n ) function of the harmonic time n . when the capacitors has different combination , b ( n ) ' s value will also change , with the inputting local measurement data , the paper studies the series and parallel resonance at the substation , and deduces that the reason the capacitor ' s fuse of tang6c is frequently interrupted is that its capacitor current contains a large number of 5th harmonics , and that the reason the discharging pt of tang7c capacitor being exploded is also that the 7th and 9th harmonic currents are amplified 據此,對該站進行了串聯諧振分析和并聯諧振分析,并結合測試數據和有關變電站的運行記錄,指出了導致該站電容器湯6c頻繁燒保險的主要原因是5次諧波電流含量偏高,引起湯7c放電pt爆炸也是因為7次和9次諧波電流被放大。針對這些導致湯陰變電站補償電容器故障的原因,提出了相應的諧波治理措施,包括針對湯6c電容器5次諧波電流含量偏高的原因,提出了停運湯6c電容器或者通過把湯sc電容器的部分容量并入湯6c電容器(湯sc其余部分停運)以增加湯6c諧波承受能力的措施;針對# 2變低壓側7次和9次諧波電流被放大的現象,提出了在湯7c電容器上加裝一定百分比的串聯電抗器的措施。
