如何選擇試驗變壓器廠家

發布日期:2017-12-02 作者: 點擊:

試驗變壓器是做耐壓試驗的基本試驗設備,生產試驗變壓器廠家也很多,各種產品質量也是參差不齊,價格相差也比較大。使用不合格的試驗變壓器,不但會影響電力設備的安全運行,還會對人身安全造成影響。 

 試驗變壓器的質量好壞對電力設備的安全運行有重大影響。試驗變壓器是用于對各種電氣產品、電器元件、絕緣材料等進行規定電壓下的絕緣強度試驗,考核產品的絕緣水平,發現被試品的絕緣缺陷,衡量過電壓的能力設備。耐壓試驗是保證電力設備安全運行的一種重要手段。電力設備在運行中,絕緣長期受著電場、溫度和機械振動的作用會逐漸發生劣化形成缺陷。交流耐壓試驗是鑒定電力設備絕緣強度最有效和最直接的方法,是預防性試驗的一項重要內容。此外,由于交流耐壓試驗電壓一般比運行電壓高,因此通過試驗后,設備有較大的安全裕度。
