很多電真空發(fā)射機(jī)都是以機(jī)柜的形式安裝,整個(gè)發(fā)射機(jī)是一個(gè)完整的電磁系統(tǒng),除了電磁信號(hào)的接口以外,在本系統(tǒng)內(nèi)要解決各種的兼容問題,不管是熱輻射還是電磁輻射都要滿足發(fā)射機(jī)系統(tǒng)的要求。真空管發(fā)射機(jī)用發(fā)射單元、高壓電源及PFC各自封裝成箱體,箱體單元之間通過電纜連接,每個(gè)單元都要滿足發(fā)射機(jī)系統(tǒng)的兼容性要求,由于箱體之間散熱條件嚴(yán)酷,所以采用密閉的水冷散熱。

  發(fā)射單元箱體設(shè)計(jì)時(shí),為了滿足總質(zhì)量和強(qiáng)度第要求,用硬鋁作為面板材料。拼裝時(shí),把一部分不拆分面板進(jìn)行焊接(硬鋁的攪拌摩擦焊),提高了電磁兼容的密閉性、箱體的結(jié)構(gòu)強(qiáng)度及箱體內(nèi)部的空間利用率。

  電真空發(fā)射機(jī)電磁干擾途徑有傳導(dǎo)耦合、感應(yīng)耦合、共阻抗耦合和輻射耦合。其中感應(yīng)耦合又分為電傳導(dǎo)感應(yīng)耦合和磁感應(yīng)耦合。電傳導(dǎo)感應(yīng)耦合指,若兩導(dǎo)線之間存在分布電容,當(dāng)其中一根導(dǎo)線上的電壓通過電容耦合到另一根導(dǎo)線上時(shí),就會(huì)對(duì)該導(dǎo)線所連的敏感電路形成干擾,其干擾電壓與源電壓、頻率、兩導(dǎo)線間的分布電容以及電路阻抗有關(guān),這些參數(shù)決定了電路的干擾強(qiáng)弱。

步進(jìn)電機(jī)的虛擬儀器控制系統(tǒng)由PC,F(xiàn)TDIUSB模塊,電壓轉(zhuǎn)換模塊,達(dá)林頓管和步進(jìn)電機(jī)組成。軟件由LabVIEW編輯完成并通過一根USB數(shù)據(jù)線直接控制USB模塊。因?yàn)閁SB模塊的輸出電壓是3.3伏,而電機(jī)驅(qū)動(dòng)模塊需要的輸入電壓是5伏,所以需要一個(gè)電壓轉(zhuǎn)換模塊來轉(zhuǎn)換電壓和電流。

  電機(jī)驅(qū)動(dòng)模塊采用的是ULN2803A8排達(dá)林頓管,每個(gè)芯片可以控制2個(gè)步進(jìn)電機(jī)。步進(jìn)電機(jī)采用的是4相12伏步進(jìn)電機(jī)。因?yàn)椴竭M(jìn)電機(jī)的工作電壓為12V,對(duì)于達(dá)林頓管單條引腳來說,負(fù)載較大。

  模塊初始化程序首先要啟用設(shè)備,系統(tǒng)軟件采用的是獲取設(shè)備名稱的方式。值得一提的是,每次使用FTDIUSB模塊都清理前一次運(yùn)行系統(tǒng)緩存,好的方式就是在程序打開設(shè)備后放置一個(gè)重置模塊。在重置設(shè)備以后再設(shè)置設(shè)備的運(yùn)行模式。

  在實(shí)際應(yīng)用中,只要按電機(jī)的使用說明按規(guī)律給電機(jī)各個(gè)引腳加電壓,所以USB模塊在運(yùn)行的時(shí)候,相應(yīng)的引腳只要給出相應(yīng)的高低電平就行了。

分析其原因有兩種可能,一是炮線離電纜太近,爆炸機(jī)的高壓放電通過電磁感應(yīng)影響電纜數(shù)據(jù)傳輸。二是爆炸機(jī)的高壓起爆電流通過爆炸機(jī)內(nèi)部串音影響到井口信號(hào)等輔助參數(shù)回路,進(jìn)而通過地震電纜傳輸時(shí)干擾電纜的正常傳輸,而產(chǎn)生嚴(yán)重的傳輸錯(cuò)誤。

  實(shí)驗(yàn)表明后者的可能性更大。地震電纜的線間電容對(duì)數(shù)據(jù)信號(hào)的傳輸有很大的影響,數(shù)字信號(hào)的傳輸受電容影響。模擬部分遙測(cè)地震電纜的模擬部分,實(shí)際上只是采集站到檢波器串之間很少的一部分。而正是這一部分,在很大程度上影響到采集質(zhì)量,決定著電纜的性育旨??偟膩碚f,地震電纜與采集質(zhì)量密切相關(guān),應(yīng)引起地球物理工作者的高度重視。 外界的隨機(jī)干擾工頻干擾,環(huán)境噪聲等,很容易通過這一部分直接作用于地震信號(hào),影響信號(hào)的真實(shí)性?,F(xiàn)行地震電纜大多采用夾片式連接器與檢波器串相連接,由于它暴露在外,極易產(chǎn)生漏電和串人外界干擾。更為嚴(yán)重的是,夾片式連接器,因插把上的鐵青銅等材料制成的彈簧片,極易老化而失去彈性,造成接觸不良和接觸電阻差異,影響各道阻抗的一致性從而影響各道的輸人信號(hào)幅度。夾片的接觸電阻還會(huì)隨外部微振干擾或地震放炮激發(fā)振動(dòng)而隨機(jī)變化,形成干擾源,嚴(yán)重影響采集質(zhì)量。

過充電對(duì)正極材料的破壞性。充放電過程僅進(jìn)行了2次,就不能再進(jìn)行充電,且前2次的充放電效率極低,只有1.53和1.67,充電電壓平臺(tái)也急劇下降。此時(shí),電池已經(jīng)完全損壞。分析有以下原因:第一,過充電時(shí)鋁箔容易發(fā)生局部點(diǎn)蝕,導(dǎo)致內(nèi)阻增加,容量下降。在極端情況下,由于鋁箔只有15Lm厚,有可能使其受到破壞,導(dǎo)致電池失效。第二,由于電池的充放電過程是一個(gè)氧化還原過程,大電流過充電時(shí),PPySiO復(fù)合正極材料就會(huì)被過氧化,聚合物的微觀組織結(jié)構(gòu)發(fā)生破壞,導(dǎo)致?lián)诫s陰離子“無路可回”,因此放電容量極低。

  對(duì)電池進(jìn)行小電流正常充放電時(shí),電池正常循環(huán)148h后依舊保高分子材料科學(xué)與工程持了較高的容量和接近100的充放電效率??梢?,鋰聚合物二次電池適宜在小電流充放電制度下進(jìn)行正常的測(cè)試。

  復(fù)合材料作正極,組裝成鋰聚吡咯二次電池。初步探討了集電極隔膜厚度正極片成型壓力及過充放電對(duì)電池性能的影響。結(jié)果表明,以鋁箔為集電極制備的電池,其比容量和充放電效率較以鋁網(wǎng)作集電極為優(yōu)。正極片的成型壓力過大或過小都會(huì)影響電池的綜合性能,經(jīng)過篩選比較,得出當(dāng)壓力為20MPa時(shí),電池性能優(yōu)。隔膜的薄厚對(duì)正極材料的容量影響不大,但對(duì)充放電效率的影響顯著。隔膜越厚,循環(huán)效率越低;隔膜越薄,循環(huán)效率越高。
