執行標準：DL/T848.2-2004

產品用途          YD 系列油浸式試驗變壓器又稱升壓器，它是發電站、供配電系統及科研單位等廣大用戶的基本試驗設備，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。                          YD 系列產品鐵芯為單相芯式，采用優質冷軋取向硅鋼片疊制而成，緊固方式采用鋼材作夾件。高壓線圈為圓筒多層塔式，由優質聚酯漆包線及高耐壓值絕緣材料繞制而成。低壓線圈在外，儀表線圈為一獨立繞組，一般情況下為100V。殼體為八角形，10kVA以上的試驗變壓器裝有可移動的鐵輪。具有重量輕、體積小、移動方便、性能優越等特點。  試驗變壓器參數   規格  容量kVA低壓側高壓側測量變比60分鐘溫升℃阻抗電壓％空載電流％  質量kg  外形尺寸長Х寬Х高mmХmmХmm 電壓V電流A電壓kV電流mA 1.5/501.52007.550305005010< 419.5200Х275Х640 3/5032001550605005010< 427240Х300Х690 5/50520025501005005010< 452250Х355Х710 10/501020050502005005010< 480260Х375Х750 15/501540037.550300500508< 4120270Х420Х800 20/50204005050400500508< 4140285Х440Х820 30/50304007550600500508< 4155295Х386Х840 50/5050400125501000500508< 4184320Х416Х910 10/100102005010010010005010< 4135350Х475Х1300 15/1001540037.51001501000508< 4150510Х390Х1320 20/10020400501002001000508< 4215540Х400Х1340 30/10030400751003001000508< 4250560Х410Х1360 50/100504001251005001000508< 4290600Х460Х1410 10/150102005010066.715005010< 4180265Х380Х1750 15/1501540037.51501001500508< 4200510Х390Х1800 20/1503040050150133.31500508< 4220540Х415Х1800 30/15030400751502001500508< 4280560Х430Х1800 50/15050400125150333.31500508< 4340640Х490Х1850   直流技術參數：          交直流兩用型試變的參數同上表，直流參數中的額定直流電壓為交流的1.4倍，額定直流電流為交流電流的0.7倍。高壓絕緣耐壓試驗：
