ETCR7300A-大口徑三相鉗形(xing)功率(lv)表

一．簡介

  ETCR7300A大(da)(da)口(kou)徑(jing)三相鉗形功(gong)(gong)率(lv)(lv)表(biao)是(shi)我公司精心(xin)研制的(de)(de)一款專為現場測量三相交流電(dian)(dian)壓(ya)、電(dian)(dian)流、電(dian)(dian)壓(ya)間(jian)相位(wei)、電(dian)(dian)壓(ya)電(dian)(dian)流間(jian)相位(wei)、頻(pin)率(lv)(lv)、相序(xu)、電(dian)(dian)能、有功(gong)(gong)功(gong)(gong)率(lv)(lv)、無功(gong)(gong)功(gong)(gong)率(lv)(lv)、視在功(gong)(gong)率(lv)(lv)、功(gong)(gong)率(lv)(lv)因數、總功(gong)(gong)率(lv)(lv)等(deng)的(de)(de)多功(gong)(gong)能、數字式、智(zhi)能儀表(biao)，鉗頭大(da)(da)口(kou)徑(jing)(80mm×80mm：可鉗φ80mm電(dian)(dian)纜，或96mm×4mm扁鋼地線(xian)(xian)），使用非常方(fang)便，*兼容大(da)(da)口(kou)徑(jing)鉗形漏電(dian)(dian)流表(biao)及微功(gong)(gong)率(lv)(lv)鉗表(biao)的(de)(de)功(gong)(gong)能，還能用于(yu)判別(bie)變壓(ya)器接線(xian)(xian)組別(bie)、感性(xing)、容性(xing)電(dian)(dian)路(lu)，讀出差動保(bao)護各(ge)組CT之間(jian)的(de)(de)相位(wei)關系，檢查電(dian)(dian)度表(biao)的(de)(de)接線(xian)(xian)正確與否，檢修線(xian)(xian)路(lu)設(she)備等(deng)，為用電(dian)(dian)檢查人員(yuan)提供一種安(an)全、準確、便捷的(de)(de)新型(xing)電(dian)(dian)力儀表(biao)。

  ETCR7300A大口徑三相鉗(qian)形功(gong)(gong)率表其鉗(qian)頭鐵芯(xin)選(xuan)用特殊(shu)合金，采用磁性屏蔽技術，幾乎不受外界磁場的影響，確保(bao)了(le)常(chang)年無間斷測(ce)量的高精度、高穩定(ding)性、高可靠性，儀表具有RS232接口，可存儲200組數據(ju)(ju)，通過系統軟(ruan)件上傳所存數據(ju)(ju)到電腦，實現歷史數據(ju)(ju)讀取、查詢、保(bao)存、打印(yin)等功(gong)(gong)能。儀表還具有背光功(gong)(gong)能、數據(ju)(ju)保(bao)持功(gong)(gong)能，是電工安全檢測(ce)的*工具。
