例如,对于两绕组delta/wye电力变压器,其中在电力变压器的delta侧上有wye连接的电流互感器(25000:5比),在变压器的wye侧上有delta连接的电流变换器(4000:5比),设置:变压器类型:“2W外部连接”绕组1相CT主绕组:“25000:5”绕组2相CT主变压器:(4000/):5或“2309:5”•额定负载下的负载损耗:输入额定负载下负载损耗。该值用于计算谐波降额系数和绝缘老化功能。这是一个自动测距设定点,取决于低电压绕组额定值;请参阅下表中的范围•低电压绕组额定值:输入低电压绕组的额定值。此选择会影响上表所示的绕组1(3)标称电压、绕组1(三)额定负载、小分接头位置电压和每个分接头的电压增量的范围。•额定绕组温升:确定绝缘类型;用于计算绝缘老化。•空载损耗:来自变压器数据。这是绝缘老化计算所必需的。这是一个自动范围设定点,取决于低压绕组额定值;请参阅上表中的范围。•冷却类型:来自变压器数据;绝缘老化计算所需。•额定顶油上升超过环境:绝缘老化计算所需•XFMR THRML容量:绝缘老化分析所需。从变压器制造商处获取
For example, for a two-winding delta/wye power transformer with wye-connected current transformers on the delta side of the power transformer (25000:5 ratio), and deltaconnected current transformers on the wye side of the transformer (4000:5 ratio), set: TRANSFORMER TYPE: “2W External Connection” WINDING 1 PHASE CT PRIMARY: “25000:5” WINDING 2 PHASE CT PRIMARY: (4000 / ):5 or “2309:5” • LOAD LOSS AT RATED LOAD: Enter the load loss at rated load. This value is used for calculation of harmonic derating factor, and in the Insulating Aging function. This is an auto-ranging setpoint dependent on the LOW VOLTAGE WINDING RATING value; see ranges in the following table • LOW VOLTAGE WINDING RATING: Enter the low voltage winding rating. This selection affects the ranges of WINDING 1(3) NOM ø-ø VOLTAGE, WINDING 1(3) RATED LOAD, MINIMUM TAP POSITION VOLTAGE, and VOLTAGE INCREMENT PER TAP as shown in the table above. • RATED WINDING TEMP RISE: Determines the type of insulation; for use in the computation of insulation aging. • NO-LOAD LOSS: From the transformer data. It is required for insulation aging calculations This is an auto-ranging setpoint dependent on the LOW VOLTAGE WINDING RATING value; see ranges in the above table. • TYPE OF COOLING: From Transformer data; required for insulation aging calculations. • RATED TOP OIL RISE OVER AMBIENT: Required for insulation aging calculations • XFMR THRML CAPACITY: Required for insulation aging calculations.
