電力變壓器

Not established reliability indicator, 9.980 inches minimum single mounting facility single center group and 10.020 inches maximum single mounting facility single center group center to center distance between mounting facilities parallel to length, 9.480 inches minimum single mounting facility single center group and 9.520 inches maximum single mounting facility single center group center to center distance between mounting facilities parallel to width, 0.615 inches minimum single group and 0.635 inches maximum single group mounting hole diameter, 60.0 hertz nominal single component frequency rating, three phase to single phase single component and three phase to three phase single component input-output phase relationship

由一個或多個初級繞組和一個或多個次級繞組組成的變壓器。它可以設計為直接連接到交流電源以改變次級電壓和安培，或者設計為消除電路之間以整體一比一的電壓比的金屬互連，有或沒有額外的輸出繞組，或設計用於在不同的輸入或負載條件下自動將恆定輸出電壓保持在指定限制內的物品。還包括具有通過電壓抽頭、比率調節器或類似設計的設備以漸進增量機械改變匝數比或電感耦合的專案。對於具有輸入和輸出電路共用繞組的變壓器，請參閱變壓器 （1）、電源、自耦變壓器。不包括：變壓器 （1）、脈衝。
