zpw2000a区间轨道电路调整作业指导书
ZPW2000A区间轨道电路调整作业指导书ZPW2000A区间轨道电路调整作业程序及标准项目文字说明安全风险及卡控重点提示图片说明需求确定上报流转调整区段确定：ZPW2000A区间轨道电路调整分为主轨道调整及小轨道调整，在各级微机监测调看中发现区间轨道电路主轨出、小轨出电压值不在《调整表》范围值内以及已经登记需调整的区段。
记轴区段严禁调整，经指挥中心同意后切换记轴。
车间副主任负责需调整区段的汇总、收集工作并预先做好人员安排和调整进度卡控，按I级维修组织。
人员不足，职务不够，严禁作业。
工区按需求提报调整流转，经车间、试验室两级审批，确认调整。
必须履行审批手续。
点前核实准备调整前需将待调整区段名称，对应区段主轨出、小轨出电压值、C3（R11）连接线端子、C4(R12)连接线端子、短接线的端子号进行记录，以防调整失败时恢复原状，调查时只能目视观察，不可触碰配线及设备。
同时，参考《调整表》调整目标值，计算出拟定接收电平等级（公式：拟定轨出值/实际轨入值*116=拟定电平等级），再参照《维规》确定出新C3（R11）连接线端子、C4(R12)连接线端子、短接线的端子号并记录，以便在天窗调整作业中作为参考。
1.不可触碰配线及设备，防止人为故障。
2.将不调整区段用安全警示带悬挂隔离，防止误调。
3.确定出上行、下行调整区段并标注。
点前将设备原配线端子位置进行调查记录，同时预先记录好准备调整的端子号。
工区申请例如某站，某区段主轨出电压809mv，而调整表规定值为242-697mv，超出《调整表》规定范围，因此，需要调整。
车间审核试验室审批调整前，应将42*0.15mm的多股铜芯线裁成长度为18-20cm，芯线剥头长度为0.5cm左右的线段，线头直接扭绞，不需吃锡。
剥头不可过长，防止短路。
天窗给点40分钟前，作业人员应共同进入机械室，准备好使用工具，并认真确认待调整区段所在组合架、组合层以及发送器、衰耗器等设备位置，做到工区作业人员与盯控干部双人确认。

ML2000说明书
小接地电流系统是指中性点不接地或经消弧线圈接地或经电阻接地的电力系统。
小接地电流系统中最常见的故障是单相接地。
发生单相接地时电流较小，单相接地时不形成短路回路，电力系统安全运行规程规定接地故障后可继续运行1至2小时，单整个系统非故障相对地电压升高3倍。
若不及时处理，极易发展为二相短路，使故障扩大。
小接地电流系统中发生单相接地故障时，凡是对地有电容的线路都将有零序电流流过。
但由于零序电流较小，又有很大的分散性，选择接地线路具有一定困难，若系统中有消弧线圈则困难更大。
小接地电流系统单相接地故障检出常用的选线方法有功率方向法、谐波分析法、信号注入法、首半波分析法、小波分析法等多种方法。
经验表明，单靠一种方法不可能排除误选和漏选，这也许是目前许多接地选线装置正确率不高的主要原因。
特别是由于PT 断线、系统铁磁谐振等的影响，常常导致误启动，单相接地过渡电阻变化而引起的零序电流变化也会使选线的准确率降低。
HY-ML2000型小电流接地保护装置是我公司研发人员近期研制开发的新一代小接地电流系统接地故障选线和保护装置。
在总结了十几年来各种小电流接地选线装置成功和失败的经验和教训之后，HY-ML2000型小电流接地保护装置在软硬件设计上进行了重大改进，使准确率大大提高。
装置的主要特点如下：1．针对中性点不接地、经消弧线圈接地和经电阻接地等不同的接地方式和接地工况，采用各自适应的选线算法，确保各种选线算法工作在其有效范围之内，提高了选线的准确性； 2． 算法可严格鉴别接地与PT 断线和铁磁谐振，避免了误启动；3． 引入了相对测量概念和自适应跟踪技术，大大提高了故障电流检测的灵敏度，降低了误判和漏判的概率； 4． 集选线与保护为一体，可直接动作于跳闸。
小接地电流系统发生单相接地故障后， PT 开口三角处产生零序电压。
理论分析结果是：故障线路零序电流等于非故障线路零序电流之和。
故障线路零序电流应该是最大的。
但由于实际现场CT 误差、装置内CT 误差、测量误差等原因，实际计算值可能并非最大，也可能是第二大或第三大。
