【摘要】：電真空開(kāi)關(guān)器件由于它的高耐壓能力在高電壓大電流領(lǐng)域有著不可替代的作用。本文涉及的具有空心陰極結(jié)構(gòu)的偽火花開(kāi)關(guān)管,是一種工作在帕邢曲線左支的新型的低氣壓冷陰極脈沖功率調(diào)制開(kāi)關(guān),它的工作原理是基于氣體放電理論,通過(guò)觸發(fā)空心陰極效應(yīng),從而產(chǎn)生大量的電子,最終導(dǎo)通偽火花開(kāi)關(guān)管。相比于傳統(tǒng)電真空開(kāi)關(guān)器件,它具有放電電流大、工作電路簡(jiǎn)單以及壽命長(zhǎng)的明顯優(yōu)勢(shì)。筆者在讀研期間,參與了關(guān)于偽火花開(kāi)關(guān)管的設(shè)計(jì),成功研制出了可以穩(wěn)定觸發(fā)、導(dǎo)通的偽火花開(kāi)關(guān)管。工作中,搭建了有效簡(jiǎn)潔的測(cè)試電路,對(duì)偽火花開(kāi)關(guān)管的性能進(jìn)行測(cè)試分析,給出了偽火花開(kāi)關(guān)管工作的放電波形,從理論角度研究了偽火花開(kāi)關(guān)管放電過(guò)程的各個(gè)階段,補(bǔ)充了偽火花開(kāi)關(guān)管的放電理論。并找出影響偽火花開(kāi)關(guān)管性能的主要因素,針對(duì)影響其觸發(fā)性能和放電性能的因素進(jìn)行了對(duì)比測(cè)試實(shí)驗(yàn)。通過(guò)對(duì)偽火花開(kāi)關(guān)管觸發(fā)性能和放電性能的相關(guān)因素對(duì)比實(shí)驗(yàn)的結(jié)果分析,發(fā)現(xiàn)了偽火花開(kāi)關(guān)管在設(shè)計(jì)方面還有一些不足,針對(duì)原設(shè)計(jì)中耐壓偏低和觸發(fā)電壓過(guò)高的問(wèn)題,對(duì)偽火花開(kāi)關(guān)管進(jìn)行了結(jié)構(gòu)上的改進(jìn)。隨后,在相同測(cè)試條件下,對(duì)偽火花開(kāi)關(guān)管改進(jìn)前后的性能進(jìn)行了對(duì)比測(cè)試實(shí)驗(yàn),對(duì)比了改進(jìn)前后偽火花開(kāi)關(guān)管的性能并對(duì)其進(jìn)行理論分析,驗(yàn)證了改進(jìn)方法的可行性。
[Abstract]:Because of its high voltage resistance, the vacuum switch device plays an irreplaceable role in the field of high voltage and high current. The pseudo-spark switch with hollow cathode structure is discussed in this paper. It is a new type of low pressure cold cathode pulse power modulation switch working on the left side of the Pasing curve. Its working principle is based on the theory of gas discharge, and by triggering the hollow cathode effect, a large number of electrons are produced. Compared with the traditional vacuum switch, it has the advantages of large discharge current, simple working circuit and long life. The author took part in the design of pseudo-spark switch during his graduate school. The pseudo-spark switch can be stably triggered and switched on successfully. In the work, an effective and concise test circuit is built, the performance of the pseudo-spark switch is tested and analyzed, and the discharge waveform of the pseudo-spark switch is given. In this paper, the discharge process of pseudo-spark switch tube is studied theoretically, the discharge theory of pseudo-spark switch tube is supplemented, and the main factors influencing the performance of pseudo-spark switch tube are found out. The factors affecting the trigger performance and discharge performance of pseudo-spark switch tube are compared and tested, and the results of the experiment are analyzed by comparing the relevant factors of trigger performance and discharge performance of pseudo-spark switch tube. It is found that there are still some deficiencies in the design of pseudo-spark switch tube. In view of the problems of low voltage and high trigger voltage in the original design, the structure of pseudo-spark switch tube is improved. Then, under the same test conditions, The performance of pseudo-spark switch before and after improvement is compared and tested. The performance of pseudo-spark switch before and after improvement is compared and the theoretical analysis is carried out to verify the feasibility of the improved method.
