标准摘要
[中文适用范围]: IEC 61243 的这一部分适用于标称电压不超过 1000 V 交流和/或 1500 V 直流且低于 500 Hz(标称频率)的电气系统中使用的两极电压检测器。探测器类型分类如下: 电压等级 A: 500 V 交流/750 V 及以下;电压等级 B:高达并包括 1000 V 交流/1500 V 直流 IEC 61243 的这一部分也适用于补充功能,例如相位指示、旋转磁场指示和连续性检查(参见附录 E)。此外,它还适用于鳄鱼夹、可拆卸引线和接触电极延长件等配件。除另有规定外,本标准所定义的电压均指三相系统的相间电压。探测器可用于三相系统以外的系统,然后使用适用的相间或相对地(地)电压来确定工作电压。本标准涵盖的低压探测器并不旨在提供绝对值的测量。测量设备不包括在本标准范围内。注 - IEC 61010-1 和 IEC 61010-2-031 中规定了测量设备的要求。 [外文原描述]: Is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1500 V d.c and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 V d.c.; voltage class B: up to and including 1 000 V a.c./ 1 500 V d.c. Low-voltage detectors covered by this standard are not intended to provide measurement of absolute values. Measuring devices are excluded form this standard. NOTE - The requirements for measuring devices are specified in IEC 61010-1 and IEC 61010-2-031. The contents of the corrigenda of May 2000 and December 2000 have been included in this copy.
