變壓器介損測試儀

是測(ce)(ce)量(liang)各種高(gao)(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)力設備(bei)介(jie)(jie)損(sun)正(zheng)切值及(ji)電(dian)(dian)(dian)(dian)(dian)容量(liang)的(de)精度測(ce)(ce)試(shi)(shi)儀(yi)(yi)器(qi)(qi)。儀(yi)(yi)器(qi)(qi)為(wei)一體化結構(gou)，內(nei)置介(jie)(jie)損(sun)測(ce)(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)橋，可變(bian)頻(pin)調(diao)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源，升壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器(qi)(qi)和SF6 高(gao)(gao)穩定(ding)度標準(zhun)電(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)。測(ce)(ce)試(shi)(shi)高(gao)(gao)壓(ya)(ya)(ya)源由儀(yi)(yi)器(qi)(qi)內(nei)部(bu)的(de)逆變(bian)器(qi)(qi)產生，經變(bian)壓(ya)(ya)(ya)器(qi)(qi)升壓(ya)(ya)(ya)后用(yong)于被試(shi)(shi)品測(ce)(ce)試(shi)(shi)。頻(pin)率(lv)可變(bian)為(wei)45Hz或55Hz，55Hz或65Hz，采用(yong)數字陷波技術，避開了工頻(pin)電(dian)(dian)(dian)(dian)(dian)場(chang)對測(ce)(ce)試(shi)(shi)的(de)干(gan)擾(rao)，從根(gen)本上解(jie)決了強電(dian)(dian)(dian)(dian)(dian)場(chang)干(gan)擾(rao)下(xia)準(zhun)確測(ce)(ce)量(liang)的(de)難題。同時適用(yong)于全(quan)部(bu)停電(dian)(dian)(dian)(dian)(dian)后用(yong)發電(dian)(dian)(dian)(dian)(dian)機供電(dian)(dian)(dian)(dian)(dian)檢(jian)測(ce)(ce)的(de)場(chang)合。該儀(yi)(yi)器(qi)(qi)配以(yi)絕(jue)緣(yuan)油杯可測(ce)(ce)試(shi)(shi)絕(jue)緣(yuan)油介(jie)(jie)質損(sun)耗。

可以有(you)效地發現(xian)電(dian)(dian)器設備(bei)(bei)絕(jue)緣的整體(ti)受潮劣(lie)化變質，以及局(ju)部(bu)缺陷(xian)等，在電(dian)(dian)工制造、電(dian)(dian)氣設備(bei)(bei)安裝、交接和預防性(xing)試驗中都(dou)廣泛(fan)應用。

變壓器介損測試儀

• 1、儀器(qi)測量(liang)準確度高，可(ke)滿足油(you)(you)介損測量(liang)要求(qiu)，因此只(zhi)需配備(bei)標準油(you)(you)杯，和(he)測試線即可(ke)實(shi)現油(you)(you)介損測量(liang)

• 2、采用變(bian)頻技術來消除現場50Hz工(gong)頻干擾，即使在強電(dian)磁(ci)干擾的(de)環境(jing)下也能測得可靠的(de)數據

• 3、過流保護功能，在試品短(duan)路或(huo)擊(ji)穿時儀器不受(shou)損壞

• 4、內附標準電容和高壓電源，便于現(xian)場測(ce)試(shi)，減少現(xian)場接線(xian)

• 5、儀器采(cai)用(yong)大(da)屏(ping)幕液晶顯示(shi)(shi)器，測試過(guo)程通過(guo)漢字菜單(dan)提(ti)示(shi)(shi)既直觀又(you)便于操作

• 變頻電源技術、自動頻率變換、模/數轉換和數據運算
• 輸出45Hz和55Hz純正弦波、提供10kV電壓、自動濾除50Hz干擾
• 大屏幕液晶顯示，過流保護功能
