LJJHBPXZ變頻串聯諧振耐壓試驗裝置

產品概述

LJJHBPXZ變頻串聯諧振耐驗(yan)裝置又叫(jiao)串(chuan)聯諧(xie)振(zhen)，分為調頻式(shi)和調感式(shi)。一(yi)般是由變(bian)頻電(dian)源(yuan)、勵磁變(bian)壓器、電(dian)抗器和電(dian)容分壓器組成。被試品(pin)的電(dian)容與(yu)電(dian)抗器構成串(chuan)聯諧(xie)振(zhen)連接方式(shi)；分壓器并聯在被試品(pin)上(shang)，用于(yu)測量被試品(pin)上(shang)的諧(xie)振(zhen)電(dian)壓，并作過壓保(bao)護信號，適用(yong)于火力、水力發(fa)電(dian)機的交流耐(nai)壓(ya)(ya)試(shi)驗 。發(fa)電(dian)機交流耐(nai)壓(ya)(ya)試(shi)驗要求采用(yong)工頻(pin)電(dian)壓(ya)(ya)，目(mu)前國標對(dui)工頻(pin)電(dian)壓(ya)(ya)的頻(pin)率定義為45Hz～65Hz，但(dan)是(shi)在很(hen)多試(shi)驗場合，要求對(dui)發(fa)電(dian)機進行(xing)的是(shi)50Hz±2Hz的交流試(shi)驗，而(er)發(fa)電(dian)機定子繞組的對(dui)地(di)電(dian)容量(liang)又比較大，國內目(mu)前大多數試(shi)驗單(dan)位采用(yong)的是(shi)諧振(zhen)變(bian)壓(ya)(ya)器(qi)對(dui)它進行(xing)試(shi)驗，但(dan)是(shi)諧振(zhen)變(bian)壓(ya)(ya)器(qi)本身很(hen)重(zhong)，動輒(zhe)上(shang)噸，現場試(shi)驗很(hen)不方(fang)便。

LJJHBPXZ變頻串聯(lian)諧振耐試驗裝置由變頻(pin)電(dian)(dian)源、勵(li)磁變壓(ya)(ya)(ya)器、高壓(ya)(ya)(ya)電(dian)(dian)抗器和(he)電(dian)(dian)容(rong)分(fen)壓(ya)(ya)(ya)器組成(cheng)。 被(bei)試品的電(dian)(dian)容(rong)與電(dian)(dian)抗器構成(cheng)串(chuan)聯(lian)(lian)諧(xie)振(zhen)(zhen)連接(jie)方式；分(fen)壓(ya)(ya)(ya)器并聯(lian)(lian)在(zai)被(bei) 試品上，用于測量被(bei)試品上的諧(xie)振(zhen)(zhen)電(dian)(dian)壓(ya)(ya)(ya)，并作過壓(ya)(ya)(ya)保護信號；調頻(pin)功(gong)率(lv)輸出(chu)經激勵(li)變壓(ya)(ya)(ya)器耦合給(gei)串(chuan)聯(lian)(lian)諧(xie)振(zhen)(zhen)回路，提供串(chuan)聯(lian)(lian)諧(xie)振(zhen)(zhen)的激勵(li)功(gong)率(lv)。
