【摘要】：為解決系統(tǒng)短路電流過(guò)大、傳統(tǒng)飽和鐵心型故障限流器限流效果和經(jīng)濟(jì)性不理想等問(wèn)題,提出一種飽和鐵心橋式故障限流器(BSFCL)。相比傳統(tǒng)飽和鐵心型故障限流器,該限流器采用橋式結(jié)構(gòu),可有效減小限流器的體積和成本;通過(guò)外加限流電感,有效提高了限流器的限流效果。首先分析飽和鐵心型橋式故障限流器的工作原理,然后建立限流器的磁路模型,并對(duì)限流器性能參數(shù)進(jìn)行詳細(xì)分析和設(shè)計(jì)。在此基礎(chǔ)上,基于Ansoft建立飽和鐵心型橋式故障限流器的場(chǎng)路耦合仿真模型,通過(guò)仿真說(shuō)明其工作原理和良好的性能,并分析不同參數(shù)對(duì)限流器限流效果的影響。最后研制了一臺(tái)220V/20A飽和鐵心型橋式故障限流器實(shí)驗(yàn)樣機(jī),實(shí)驗(yàn)結(jié)果驗(yàn)證了所提結(jié)構(gòu)和方法的有效性。
[Abstract]:In order to solve the problems such as too large short circuit current in the system and unsatisfactory current limiting effect and economy of traditional saturated core fault current limiter, a kind of saturated iron core bridge fault current limiter (BSFCLL) is proposed, which is compared with traditional saturated iron core fault current limiter. The current limiter adopts bridge structure, which can effectively reduce the volume and cost of the current limiter, and effectively improves the current limiting effect of the current limiter by applying the current limiting inductance. Firstly, the working principle of the saturated iron core bridge fault current limiter is analyzed. Then the magnetic circuit model of the current limiter is established, and the performance parameters of the current limiter are analyzed and designed in detail. Based on this, the field circuit coupling simulation model of the saturated iron core bridge fault limiter is established based on Ansoft. The working principle and good performance are illustrated by simulation, and the influence of different parameters on the current limiting effect of the current limiter is analyzed. Finally, a 220 V / 20A saturated iron core bridge fault current limiter is developed. The experimental results show that the proposed structure and method are effective.
