变压器差动保护系统调试变压器差动保护系统调试commissioning of the differ- ential protection system for transformer b ianyaqi chadong baohu xitong tiaoshi变压器睡动保护系统调试(eommissioningof the differential Proteetion system for trans-former)对流入变压器和自变压器流出的两侧电流,经电流互感器检测变换之后进行比较,其电流差值反映出变压器的内部故障情况.根据这一原理,由电流互感器、差动继电器、断路器跳闸机构组成的保护系统称为变压器差动保护系统.当电流互感器的变比和结线方式与被保护的变压器相适应时,变压器正常运行电流及变压器以外的穿越性故障电流不会使差动保护动作.空载变压器接入电源时,电源侧向变压器流入较大的励磁涌流,为减少它对保护系统的影响,消除误动作,变压器差动保护系统中设有速饱和变流器或谐波制动电路。变压器差动保护系统的调试分差动保护继电器的单体调试和差动保护系统模拟试验两个步骤. 差动保护继电器的单体调试变压器差动保护继电器依其结构特点可分为机电型、整流型、静态型等。机电型差动保护继电器由速饱和变流器、电磁动作的执行继电器、换档擂接板等组成,其调试项目主要有:(1)外观检查,插接与机械动作部分的检查和调整。(2)电磁式执行继电器的常规调试。(3)速饱和变流器的特性试验:检查各绕组极性与结线的正确性;测定变流器伏安特性曲线;通入试验电流,测定执行继电器动作时各绕组分档的动作电流安匝数,并将其整定到设计规定的范围内;测定直流助磁特性,即测定相对动作电流。=(‘/i。)和偏移系数K(1/1)间的函数关系。式中,I为速饱和变流器一次侧通入的直流试验电流(A)八为通入直流分量I时速饱和变流器一次侧的交流动作电流(A);i。为未通直流分量时的交流动作电流(A)。(4)在整定位置下测定保护继电器的整组伏安特性,即差动继电器输入差动电流信号安匝数与执行继电器线圈端电压之间的关系,以判别差动继电器工作磁通密度选取是否合适。 整流型差动保护继电器由差动元件和瞬动元件两部分组成。差动元件包括工作回路、比率制动回路、谐波制动回路及直流比较回路。调试项目主要有:(l)工作回路最小动作电流与返回电流的测定,动作电流整定。(2)比率制动回路动作特性试验。给工作回路和制动回路同时通入试验电流,测定继电器产生输出动作时两试验电流数,绘制出它们的函数关系曲线(即比率动作特性曲线),按照保护设计要求对比率动作特性进行整定。在无特殊要求时,两试验电流取同相位电流。
