YDJ交流型試驗變壓器、YDJ(Z)交直流兩用輕型高壓試驗變壓器采用優(yōu)質(zhì)冷軋硅鋼片疊制而成。線圈為同心寶塔形多層圓筒式,低壓線圈在內(nèi),高壓線圈在外;外殼為便攜式,具有體積小、重量輕、外形美觀、移動方便等優(yōu)點。
用工頻220V(10KVA及以上用380V)電源接入控制箱(臺),經(jīng)自耦調(diào)壓器調(diào)節(jié)0-220V/380V電壓輸入到試驗變壓器初級繞組。根據(jù)電磁感應原理,在次級(高壓)繞組按其與初級繞組匝數(shù)之比獲得同等倍數(shù)的電壓幅值――工頻高壓。
此工頻高壓經(jīng)高壓硅堆整流及電容器濾波可獲得直流高壓,其中幅值是工頻高壓有效值的倍。
交流試驗變壓器又稱交直流試驗變壓器、油浸式高壓試驗變壓器、油式試驗變壓器、工頻耐壓試驗裝置、高壓升壓器、交流耐壓試驗裝置、電力高壓試驗變壓器等。
