Planting soil: cultivation prior to planting in the region of 洗衣机运行正常，各电气元件绝缘性能良好，但检查发现洗衣机壳体对地有电压，而当人手紧密接触洗衣机壳体时却无触电感觉。 洗衣机壳体内的电动机、程序控制器、排水泵等电气元件，其内部的线圈与金属壳体之间形成了分布电容和绝缘电阻，有些洗衣机安装时接地不良或根本就投有接地，与用试电笔和测量仪表检查洗衣机壳体对地电压时，由于测试工具及人体对地构成并联回路，产生漏泄电流，该电流形成洗衣机壳体对地间的电压，用测量仪表即可测量出该电压，该电压超过试电笔氟泡的启辉电压时，遇试电笔发光。 由于人体电阻远小于通电线圈对壳体的绝缘电阻，如果人用手紧密握洗衣机的壳体时，相当于洗衣机壳体对地之间的电阻大大减小，这样洗衣机壳体对地的电压也就大大减小，所以此时人无触电感觉。 上述漏泄电流仅管很小，即远远小于人体触电电流的临界值，对人身安全无影响，但是(如果电气元件绝缘性能变差，则洗衣机壳体对地的电压就升高，将会导致触电事故。 安全可靠使用洗衣机时，必须使用的三芯电线，并配以三脚插头与插座，将其中的接地线牢固地与洗衣机金属外壳连接，并将其接地，保证用电的绝对安全，若无条件配用三芯电线，则必须在洗表机外壳安装一可靠的接地线，使洗衣机外壳牢固接地。 博世洗衣机直观检查法说明 直观检查是将洗衣机置于有故障的运转位置(或运转状态)，通过通电运转及手动转动，用人的感觉器官进行检查，以明确故障表现，初步判断故障原因，找出明显的故障部位。 根据有关故障现象，检查使用条件和操作方法。如电动机有嗡嗡声但不运转或工作无力，电脑洗衣机的指示灯不亮，应检查电源电压是否过低或过高;脱水时不脱水，应检查脱水桶盖是否盖好;脱水时振动大，应检查洗衣机是否放在水平结实的地面上。 直观检查是将洗衣机置于有故障的运转位置(或运转状态)，通过通电运转及手动转动，用人的感觉器官进行检查，以明确故障表现，初步判断故障原因，找出明显的故障部位。 根据有关故障现象，检查使用条件和操作方法。如电动机有嗡嗡声但不运转或工作无力，电脑洗衣机的指示灯不亮，应检查电源电压是否过低或过高;脱水时不脱水，应检查脱水桶盖是否盖好;脱水时振动大，protection measures or programmes.

Planting soil: cultivation prior to planting in the region of (2)电路有短路故障 ?进水过程中，保险丝熔断。拔去进水阀导线插头，用万用表测定进水阀的电阻，若阻值趋近于零，则进水阀线圈短路;若阻值正常，可能是进水电路短路。 ?洗涤或漂洗过程中，保险丝熔断。用万用表电阻挡分别测定电动机两绕组引出端与中线间的电阻，若阻值趋于零，则说明电动机有短路故障。测定电容器两端子间的电阻，若阻值很小，则可能电容器已击穿短路。若电动机或电容器都正常，则可能是洗涤或漂洗电路有短路故障。 ?排水过程中，保险熔断。用万用表测定排水电磁铁两端子间的电阻，若阻值很小，则说明电磁铁线圈短路。否则，可能是排水电路有短路故障。 ?脱水过程中，保险丝熔断。在脱水过程中，电动机和电磁铁都处于工作状态。因此，在脱水时，无论电动机或电容器短路，还是电磁铁线圈短路，都可使保险丝熔断。 博世洗衣机，电动机时转时停，波轮不转 维修过程 故障分析与检修;该故障有四种不同情况: (1)接通电源，保险丝立即熔断 该故障一般是电源线短路或插座内部短路造成，更换电源线或插座可排除故障。 (2)进水时保险丝熔断 该故障可能是进水阀或其内部短路引起，应更换进水阀。 (3)洗涤时保险丝熔断 程序控制器内部微型电动机短路、洗涤电动机或电容器漏电均会引起该故障，应更换相应电动机或电容器即可排除故障。 (4)排水时保险丝熔断 电磁铁线圈短路或排水电路线路短路均会引起诙故障，更换相应元件或部件，即可排除故障。 protection measures or programmes.
