质量保证QUALITY ASSURANCE

  从原材料进厂到产品出厂建立了全面质量保证体系,在生产流程中各个关键工序建立了工艺控制点,制定的工厂内控标准中各项技术指标均严于国标。
 1、电阻片检查
 *方波筛选
 *雷电冲击电流下残压测量
 *直流U1mA电压测量
 *0.75倍直流1mA电压下泄漏电流测量
 *4/10μS大电流检查
 *外观检查

 2、 避雷器出厂试验
 *复合外套外观检查
 *直流U1mA电压试验
 *工频参考电压试验
 *局部放电试验
 *密封试验
 *0.75倍直流U1mA电压下泄漏电流测量
 *持续电流试验
  A total quality control system has been set up from the incoming of raw material to delivery of products. A number of process controlpoint has been set up at each key process. Most of the technical parameters specified in the manufacturer's standard are rigorouser than the national standard.
 1、Inspection and tests for resistor:
 *Rectangular wave current filter test;
 *Measuremeut of residual voltage under lightning   *impulse current;
 *Measuremeut of DC U1mA;
 *Measuremeut of leakage current at 75% DC U1mA;
 *Inspection for 4/10μ s high current impulse;
 *Visual inspection.
 2、Routine tests for MOA;
