    數(shu)控母排(pai)加工機(ji)但(dan)目前施(shi)(shi)工現(xian)場安(an)裝的(de)漏(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)保(bao)護器(qi)由于配置不合理，經常出現(xian)末級(ji)漏(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)不動作(zuo)而(er)上一(yi)(yi)級(ji)漏(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)動作(zuo)的(de)現(xian)象，使漏(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)故障難(nan)以發現(xian)排(pai)除，嚴重的(de)會影響到施(shi)(shi)工進(jin)度，有(you)的(de)施(shi)(shi)工單位為(wei)此(ci)甚至拆除了漏(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)(dian)保(bao)護裝置，給施(shi)(shi)工安(an)全(quan)帶來了危險隱(yin)患。三相交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)： 由三個頻(pin)率相同、電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)振(zhen)幅相等、相位差(cha)互差(cha) 120 °角的(de)交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)路組成的(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)系(xi)統，叫(jiao)三相交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)。一(yi)(yi)次設備： 直(zhi)接與生(sheng)產電(dian)(dian)(dian)(dian)(dian)(dian)能和輸配電(dian)(dian)(dian)(dian)(dian)(dian)有(you)關的(de)設備稱為(wei)一(yi)(yi)次設備。包(bao)括各(ge)種(zhong)高(gao)壓斷(duan)路器(qi)、隔離開關、母線(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜、電(dian)(dian)(dian)(dian)(dian)(dian)壓互感(gan)器(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)流互感(gan)器(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)抗器(qi)、避(bi)雷(lei)器(qi)、消弧線(xian)圈、并聯電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)及高(gao)壓熔斷(duan)器(qi)等。二次設備：對一(yi)(yi)次設備進(jin)行監視、測量、操縱控制(zhi)和保(bao)護作(zuo)用的(de)輔(fu)助設備。如各(ge)種(zhong)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)、信號裝置、測量儀表(biao)、錄波記錄裝置以及遙(yao)測、遙(yao)信裝置和各(ge)種(zhong)控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜、小母線(xian)等。 　　

    高壓(ya)(ya)斷(duan)(duan)路器： 又稱高壓(ya)(ya)開關，它(ta)不僅可以切斷(duan)(duan)或(huo)閉(bi)合高壓(ya)(ya)電(dian)(dian)路中的(de)(de)(de)(de)(de)空載電(dian)(dian)流和(he)負荷電(dian)(dian)流，而且當系統發生故障時(shi)，通過繼電(dian)(dian)保(bao)護(hu)裝置的(de)(de)(de)(de)(de)作用，切斷(duan)(duan)過負荷電(dian)(dian)流和(he)短路電(dian)(dian)流。母線加(jia)工機(ji)它(ta)具有(you)(you)相當完善的(de)(de)(de)(de)(de)滅弧結構(gou)和(he)足夠的(de)(de)(de)(de)(de)斷(duan)(duan)流能力。磁性(xing)元件的(de)(de)(de)(de)(de)設計是開關電(dian)(dian)源的(de)(de)(de)(de)(de)重要部分，因(yin)為平面變(bian)壓(ya)(ya)器在提高開關電(dian)(dian)源的(de)(de)(de)(de)(de)特(te)性(xing)方面有(you)(you)著(zhu)很大的(de)(de)(de)(de)(de)優勢，因(yin)此近年來得到(dao)了廣泛(fan)的(de)(de)(de)(de)(de)應用。 　　

    對(dui)于一(yi)個(ge)理想的(de)變壓器來說，初級線(xian)(xian)圈所產(chan)生(sheng)的(de)磁(ci)通(tong)(tong)都(dou)穿過次(ci)級線(xian)(xian)圈，即沒有(you)漏磁(ci)通(tong)(tong)。而對(dui)普通(tong)(tong)變壓器來說，初級線(xian)(xian)圈所產(chan)生(sheng)的(de)磁(ci)通(tong)(tong)并非(fei)都(dou)穿過次(ci)級線(xian)(xian)圈，于是就產(chan)生(sheng)了(le)漏感，電磁(ci)耦合(he)的(de)緊(jin)密要求也無法滿足。而平面變壓器只有(you)一(yi)匝(za)(za)網狀次(ci)級繞(rao)組，這一(yi)匝(za)(za)繞(rao)組也不(bu)同(tong)于傳統的(de)漆(qi)包線(xian)(xian)，而是一(yi)片銅皮，貼繞(rao)在(zai)多個(ge)同(tong)樣大小的(de)沖(chong)壓鐵氧體磁(ci)芯表面上。
