防火電纜安載流容量降低額定值測定用工藝程序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並聯諧振分析,並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電容器的部分容量併入湯6c電容器(湯sc其餘部分停運)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。The results show that : nano - nickel powder is not useful for mh electrode during the high rate discharge phase as a conductor or additive ; superfine nickel powder is applicable for the conductor of the negative because of the good performance especially the cyclic stability at 1c rate by using 5 % ( mass percentage ) nickel powder ; the utilization of alloy, specific mass and volume capacity are increased with the decreased particle size of nickel powder in negative, however, the capacity fading rate at 1c discharge rate is also increased, so the capacity and the cyclic stability should be taken into account to make a choice of the particle size
結果表明: mh電極中加入納米鎳粉對負極的大電流放電性能不利。 mh電極中加入超細鎳粉后電極綜合性能好,尤其是1c循環穩定性,其最佳添加量為5wt 。減小鎳粉粒度提高了電極合金利用率、質量比容量、體積比容量,但增大了負極1c容量衰減率,因此鎳粉粒度的選擇應綜合考慮mh電極容量和循環穩定性。The metal oxide varistors ( mov ), as the core organ, made under japanese technology license. it have good response to steep front surge, excellent volt - amper characteristics and high discharge capability, which provides a very consistent protection merit at steep front surge, lightning surge and seitching surge, and enhances protective capability
