带电作业.电压检测器.第3部分:两极低压型

[中文适用范围]： IEC 61243 的本部分适用于手持式两极电压检测器及其附件（鳄鱼夹和可拆卸引线），用于与电气系统部件接触： ?C 适用于标称频率下不超过 1 000 V 的交流电压对于不超过 1 500 V 的直流电压，频率范围为 16 2 3 Hz 至 500 Hz@ 和/o ℃。 注：本标准中定义的交流电压是指相间电压或相间电压 接触电极延伸不属于本标准的范围。本标准涵盖的电压探测器适用于室内和室外干燥和潮湿的条件下。它们不适合在雨天使用。本标准涵盖的电压检测器不适用于连续操作。本标准涵盖的电压探测器适用于海拔 2 000 m 的地方。本标准还包括以下可用补充功能的规定（参见附录 B）： ?C 相位指示@ ?C 旋转磁场指示@ 和 ?C 连续性检查。其他补充功能不属于本标准的范围。本标准涵盖的电压检测器不被视为测量设备。测量设备的相关安全要求包含在 IEC 61010 系列中。 [外文原描述]： IEC 61243-3:2009 is applicable to hand-held two-pole voltage detectors with its accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: - for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or - for d.c. voltages not exceeding 1 500 V. Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions. Voltage detectors covered by this standard are not intended to be used for continuous operation. Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level. Voltage detectors covered by this standard are not considered as measuring devices. Relevant safety requirements for measuring devices are included in IEC 61010 series. This second edition cancels and replaces the first edition published in 1998. It is a technical revision.
