ETCR2000B钳形接地电阻仪

简介:

  ETCR2000系列钳形接地电阻仪是传统接地电阻测量技术的重大突破,广泛应用于电力、电信、气晚、油田、建筑及工业电气设备的接地电阻测量。

  ETCR2000系列钳形接地电阻仪在测量有回路的接地系统时,不需断开接地引下线,不需辅助电极,安全快速,使用简便。

  ETCR2000系列钳形接地电阻仪能测量出用传统方法无法测量的接地故障,能应用于传统方法无法测量的场合,因为ETCR2000系列钳形接地电阻仪测量的是接地体电阻和接地引线电阻的综合值。

  ETCR2000系列钳形接地电阻仪有长钳口及圆钳口之分,见下图。长钳口特别适宜于扁钢接地场合。

  另外,ETCR2000C钳形接地电阻隔仪还涌测量接地系统的泄漏电流和中性线电流。

钳形接地电阻仪ETCR2000系列型谱:

型号钳口尺寸(mm)量限量限
ETCR2000长钳口:32*650.01-1000(Ω)基型
ETCR2000B长钳口:32*650.01-1000(Ω)防爆型
ETCR2100圆钳口:φ320.01-1000(Ω)基型
ETCR2000C长钳口:32*650.01-1000(Ω)、0-20(A)多功能型
ETCR2100C圆钳口:φ320.01-1000(Ω)、0-20(A)多功能型
