575 Delta Primary Volts - 460Y/266 Secondary Volts - All Acme Drive Isolation Transformers (DITs) above 7.5kVA are wound with strip windings to ensure the lowest possible eddy current losses. All our DITs use a three leg wound core. This superior design has very low losses and quiet operation. Both of these features combine to significantly reduce losses and operation costs compared to other types of constructions. All Acme DITs up to and including the 220kVA have copper terminations. The transition from aluminum strip coil conductors to copper terminations is accomplished by a bonding process known as "Koldwelding" This process has been used by Acme for over 25 years to provide a trouble-free, permanent bonding of the two metals. * UL Type 3R Enclosures with Weather Shield on Ventilated Units (above 20 kVA). Type 2 Enclosure without weather shield. * 3-Phase 60 Hertz * 180°C and 220°C insulation systems * Acme 的增强型铁芯组件可增强静音运行 * 标称 6% 阻抗 * 设计用于交流、可调频率或直流驱动器 * 所有装置均具有全容量抽头。在 27 到 660 kVA 的装置上,抽头为 2-2 1/2% ANFC 和 2-2 1/2% BNFC。 * 全系列的 kVA 额定值涵盖所有标准驱动系统 * 充足的接线盒,便于电缆进入 * 某些尺寸可选的壁挂支架 * 应力消除:Acme 使用带状导体(高于 7.5 kVA)代替电线,用于 DIT 系列,该系列可轻松适应当今交流和直流电机驱动器中发现的严重电气和机械应力。 Acme 的静电屏蔽进一步增强了这些变压器的固有出色线路隔离 — 在所有 DIT 中免费提供。 * 较低的损耗:交流和直流驱动器产生的谐波电流会增加变压器绕组中的涡流损耗(热量)。绕组导线越厚,损耗越大。 Acme 每层使用一圈薄带状导体,与同等的绕线装置相比,可提供更低的涡流损耗。损耗越低 = 运行温度越低,变压器寿命越长。 * 降低短路力:带状绕组可最大限度地减少轴向短路力,否则会导致绕组在故障条件下发生机械位移。为了获得额外的保护,所有 7.5 kVA 及以上的型号均使用轴向长度相等的初级和次级线圈。此功能可消除轴向短路力,从而进一步提高变压器的预期寿命。 * 所有通风装置均采用带状绕组结构。
