环形变(bian)压器(qi)主要用途是作为电(dian)源变(bian)压器(qi)和隔离变(bian)压器(qi)。环(huan)(huan)形(xing)变(bian)压器(qi)在国外已(yi)有完整的(de)系(xi)列,广泛应用于计算机、医疗设(she)备、电(dian)讯、仪器(qi)和灯光照(zhao)明等(deng)方(fang)面。 环(huan)(huan)形(xing)变(bian)压器(qi)由于有优良的(de)性(xing)能(neng)价格比(bi),有良好(hao)的(de)输出特(te)性(xing)和抗干扰能(neng)力。

环形变压器的分(fen)类(lei)(lei):标(biao)准型(xing)、经济型(xing)及(ji)隔离型(xing)等三类(lei)(lei).

1)标准型电源变压(ya)器产品系列容量(liang)8~1500VA,有较(jiao)小的(de)电压(ya)调整率(lv)、满载(zai)运行温(wen)升仅为(wei)40℃,允(yun)许短(duan)时超载(zai)运行,适合于要求(qiu)高的(de)使用场(chang)合。 初次级绕组间(jian)采(cai)用B级(130℃)的(de)聚酯薄(bo)膜(mo)绝(jue)缘,要求(qiu)至少包三层绝(jue)缘带,能经受交流4000V,1min的(de)耐压(ya)试验。

2)经济(ji)型电源变(bian)压器产品系列容(rong)量50~1500VA,在(zai)保证(zheng)性能的(de)基础上力(li)求降低造价,适(shi)用于(yu)连续运(yun)行而(er)不超载的(de)使用场合,运(yun)行温升为(wei)60℃,绝缘材(cai)料等级(ji)为(wei)A级(ji)(105℃),当满负载时输出电压误(wu)差小 于(yu)3%。

3)隔离(li)(li)变(bian)(bian)(bian)压器(qi)产(chan)品系列容量(liang)50~1000VA,又可分为(wei)工业用和医疗(liao)设备用两(liang)系列。隔离(li)(li)变(bian)(bian)(bian)压器(qi)着重是它的绝(jue)缘性能(neng),初级与次级间用B级绝(jue)缘的聚(ju)酯(zhi)薄膜至少包扎4层,击穿电压大(da)于(yu)4000V,所有(you)初级引线(xian)(xian) 必须采(cai)用双绝(jue)缘导线(xian)(xian)。变(bian)(bian)(bian)压器(qi)最大(da)温升低于(yu)45℃。 医疗(liao)用的隔离(li)(li)变(bian)(bian)(bian)压器(qi)除符合上述(shu)的要(yao)求(qiu)外,还(hai)要(yao)符合UL544标准,即初级和次级绕(rao)组应具有(you)热保(bao)护,绕(rao)组与接地铜屏蔽间隔距(ju)离(li)(li)应大(da)于(yu)13mm。

此(ci)外对医疗用(yong)的隔离变(bian)压器(qi)还(hai)要求在(zai)初级绕组(zu)装(zhuang)有温度保护开(kai)关,当铁(tie)心(xin)温度达到120℃时(shi),温度保护开(kai)关断(duan)开(kai),当温度恢复正常时(shi),开(kai)关自动复位(wei)合上。 环(huan)型(xing)变(bian)压器(qi)由于不(bu)存(cun)(cun)在(zai)气隙(xi)、线圈均匀卷绕铁(tie)芯,理论上漏(lou)磁很(hen)小(xiao),也不(bu)存(cun)(cun)在(zai)线圈辐射。但环(huan)型(xing)变(bian)压器(qi)由于无气隙(xi)存(cun)(cun)在(zai),抗饱和能力差,在(zai)市电存(cun)(cun)在(zai)直(zhi)流成分时(shi)容易(yi)产生饱和,产生很(hen)强(qiang)的磁泄露。国内不(bu)少地区市电波形(xing)畸变(bian)严重,因(yin)此(ci)许多用(yong)家(jia)使用(yong)环(huan)型(xing)变(bian)压器(qi)感觉并不(bu)比EI型(xing)变(bian)压器(qi)好,甚至更差。

所谓环型(xing)(xing)(xing)(xing)变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)绝无(wu)(wu)泄(xie)(xie)露(lu)(lu),乃是(shi)(shi)(shi)(shi)因媒介误导(dao),或是(shi)(shi)(shi)(shi)因厂商出于商业宣(xuan)传需要(yao)而(er)杜撰,环型(xing)(xing)(xing)(xing)变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)磁泄(xie)(xie)露(lu)(lu)极低的(de)说(shuo)法只是(shi)(shi)(shi)(shi)在(zai)市电波型(xing)(xing)(xing)(xing)为严格的(de)正弦(xian)波时才成立。另外(wai),环型(xing)(xing)(xing)(xing)变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)还会在(zai)引线处出现较(jiao)强电 磁泄(xie)(xie)露(lu)(lu),因此(ci)环型(xing)(xing)(xing)(xing)变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)的(de)漏(lou)磁也(ye)是(shi)(shi)(shi)(shi)有(you)一定方向性(xing)的(de),实际(ji)装机(ji)时旋转环型(xing)(xing)(xing)(xing)变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi),在(zai)某个角度上获(huo)得(de)最高信(xin)噪(zao)比。如果条件允许,可(ke)考虑(lv)为变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)装一只屏(ping)蔽罩,并做妥善(shan)接地处理,该金(jin)(jin)属(shu)罩只能选用铁(tie)性(xing)材料,一般金(jin)(jin)属(shu)如铜、铝等只有(you)电屏(ping)蔽作(zuo)用而(er)无(wu)(wu)磁屏(ping)蔽作(zuo)用,不(bu)能作(zuo)为变(bian)(bian)压(ya)(ya)器(qi)(qi)(qi)屏(ping)蔽罩。

上(shang)述分(fen)析是建立在变(bian)压(ya)(ya)(ya)器(qi)(qi)选料、制作精良(liang)的(de)基础上(shang),实(shi)际多数(shu)(shu)市售变(bian)压(ya)(ya)(ya)器(qi)(qi)产(chan)品由(you)于成本压(ya)(ya)(ya)力和竞争需要(yao),未(wei)严(yan)格(ge)按行业规范(fan)设计,有时候甚(shen)至偷工减料,分(fen)析起来(lai)(lai)不可预测(ce)因素(su)较多。首先是铁(tie)(tie)芯材料的(de)品质,很(hen)多企业用导(dao)磁率(lv)较低(di)的(de)H50铁(tie)(tie)芯、边(bian)角(jiao)料甚(shen)至搀杂软铁(tie)(tie)制作变(bian)压(ya)(ya)(ya)器(qi)(qi),导(dao)致(zhi)变(bian)压(ya)(ya)(ya)器(qi)(qi)空(kong)载(zai)(zai)电(dian)(dian)(dian)流很(hen)高,铁(tie)(tie)损过大,空(kong)载(zai)(zai)发热严(yan)重;这(zhei)类变(bian)压(ya)(ya)(ya)器(qi)(qi)为降(jiang)低(di)成本、同(tong)时为掩盖铁(tie)(tie)损偏(pian)高带来(lai)(lai)的(de)电(dian)(dian)(dian)压(ya)(ya)(ya)调(diao)(diao)整(zheng)率(lv)过 大问题(ti),大幅度减少(shao)初次(ci)级线(xian)圈匝数(shu)(shu),以降(jiang)低(di)铜损的(de)方(fang)式(shi)来(lai)(lai)降(jiang)低(di)电(dian)(dian)(dian)压(ya)(ya)(ya)调(diao)(diao)整(zheng)率(lv),这(zhei)种做法更进一(yi)步增大了(le)空(kong)载(zai)(zai)电(dian)(dian)(dian)流,而空(kong)载(zai)(zai)电(dian)(dian)(dian)流偏(pian)大将直接(jie)导(dao)致(zhi)磁泄(xie)露加(jia)剧。

环(huan)(huan)型变(bian)(bian)压(ya)器(qi)问题(ti)更复杂一些。正规的环(huan)(huan)型变(bian)(bian)压(ya)器(qi)铁(tie)芯(xin)(xin)是由一条等宽硅钢带紧密卷(juan)绕(rao)(rao)(rao)而成。还是出于成本原因,多数(shu)(shu)低价环(huan)(huan)型变(bian)(bian)压(ya)器(qi)使用数(shu)(shu)条甚(shen)至数(shu)(shu)十数(shu)(shu)条硅钢带拼接,甚(shen)至使用边(bian)缘参差(cha)不齐的边(bian)角 料(liao)卷(juan)绕(rao)(rao)(rao),绕(rao)(rao)(rao)制好后用机床车(che)平,由于环(huan)(huan)型变(bian)(bian)压(ya)器(qi)线圈包绕(rao)(rao)(rao)铁(tie)芯(xin)(xin),不做破坏(huai)性解剖难以发现。机械(xie)加工对硅材料(liao)的晶(jing)格排列、相邻硅钢带间绝缘都有(you)严(yan)重(zhong)破坏(huai),这样的环(huan)(huan)型变(bian)(bian)压(ya)器(qi)无(wu)论性能或(huo)漏磁特(te)性均会 大幅度降低,即(ji)使经过退(tui)火处理也无(wu)法弥补质量上(shang)的严(yan)重(zhong)缺陷。

杂散(san)的(de)电(dian)(dian)(dian)磁(ci)波(bo)(bo)主(zhu)要来自有(you)源音(yin)箱的(de)功率(lv)(lv)输(shu)(shu)出(chu)导线、扬声器(qi)及功率(lv)(lv)分(fen)频器(qi)、无线发射设备和计算(suan)机(ji)主(zhu)机(ji),产生原(yuan)因在这里(li)不做(zuo)深(shen)入讨论。杂散(san)电(dian)(dian)(dian)磁(ci)波(bo)(bo)在传输(shu)(shu)、感应的(de)形(xing)式上(shang)与(yu)电(dian)(dian)(dian)源变压(ya)器(qi)类(lei)似,杂散(san)磁(ci) 场频率(lv)(lv)范围很宽,有(you)用家反映有(you)源音(yin)箱莫(mo)名其(qi)妙接收到当(dang)地电(dian)(dian)(dian)台广播就是典型的(de)杂散(san)电(dian)(dian)(dian)磁(ci)波(bo)(bo)干扰。

另外一个(ge)需引起重视(shi)的(de)干扰源为整流电(dian)(dian)(dian)(dian)路。滤(lv)波(bo)电(dian)(dian)(dian)(dian)容(rong)(rong)在开(kai)机进入正(zheng)常状态后,充(chong)电(dian)(dian)(dian)(dian)仅集中在交(jiao)流电(dian)(dian)(dian)(dian)峰值(zhi)时,充(chong)电(dian)(dian)(dian)(dian)波(bo)形(xing)是(shi)一个(ge)宽(kuan)度较窄(zhai)的(de)强脉(mai)冲(chong),电(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)越(yue)大(da),脉(mai)冲(chong)强度也越(yue)大(da),从电(dian)(dian)(dian)(dian)磁干扰角度看, 滤(lv)波(bo)电(dian)(dian)(dian)(dian)容(rong)(rong)并非越(yue)大(da)越(yue)好,整流管(guan)与滤(lv)波(bo)电(dian)(dian)(dian)(dian)容(rong)(rong)之间(jian)走线应尽量(liang)缩短,同时尽量(liang)远离功(gong)放电(dian)(dian)(dian)(dian)路,PCB空间(jian)不允许则尽量(liang)用地线包络。
