575 Delta Primary Volts - 230Y/133 Secondary Volts - 所有 Acme Drive Isolation Transformers (DITs) 7.5kVA 以上均采用箔式绕组，以确保尽可能低的涡流损耗。我们所有的 DIT 都使用三柱式绕线铁芯。这种卓越的设计具有极低的损耗和安静的运行。与其他类型的结构相比，这两种特性相结合可显着降低损耗和运行成本。高达 220kVA（包括 220kVA）的所有 Acme DIT 均采用铜端子。铝箔线圈导体到铜端子的过渡是通过一种称为 "Koldwelding" 的粘合工艺实现的。Acme 使用此工艺已有 25 年以上的历史，可为两种金属提供无故障的永久粘合。 * 7.5–20.0 kVA are encapsulated, UL 3R * 3-Phase 60 Hertz * 180°C and 220°C insulation systems * Acme’s reinforced core assemblies enhance quiet operation * Nominally 6% impedance * Designed for use with AC, adjustable frequency or DC drives * Full capacity taps are featured on all units. On 7.5 through 20 kVA units, taps are 1-5% ANFC and 1-5% BNFC. * Full range of kVA ratings cover all standard drive systems * Ample wiring compartment for easy cable entry * Optional wall mounting brackets for certain sizes * Stress relief: Acme uses strip conductors (above 7.5 kVA) instead of wire for a DIT series that easily accommodates the severe electrical and mechanical stresses found in today’s AC & DC motor drives. The inherent excellent line isolation of these transformers is further enhanced with the extra protection of Acme’s Electrostatic Shield — free in all DIT’s. * Lower losses: The harmonic currents generated by AC & DC drives increase eddy current losses (heat) in transformer windings. The thicker the winding conductor, the greater the losses. Acme uses one turn per layer of thin strip conductor which provides lower eddy current losses than comparable wire wound units. Lower losses = cooler operation and longer transformer life. * Reduced short circuit forces: Strip windings minimize axial short circuit forces that can cause mechanical displacement of the windings under fault conditions. For extra protection all designs 7.5 kVA and above use primary and secondary coils of equal axial length. This feature tends to negate axial short circuit forces, further improving transformer life expectancy.
