江苏春晨电缆有限公司生产YC橡套电缆，杂项电气装置的排障

The barrier of miscellaneous electrical equipment

杂项设备包括便携式电气设备、双绝缘工具、延长线、变压器，以及通过独立的电源线接收电力的电气设备。对这些设备进行绝缘电阻测试是定期维护程序的一部 分，也是OSHA和NEC®标准的要求。

Miscellaneous devices include portable electrical equipment, double insulated tools, extension lines, transformers, and electrical equipment that receives electricity through independent power lines. Insulation resistance testing for these devices is part of the periodic maintenance procedure and is also required by the OSHA and NEC standards.

在对大多数马达和其它电气装置进行排障 时，尽管可以使用标准的绝缘电阻技术指标，但是特定的环境则要求使用更髙的电 阻技术指标。大多数给出的技术指标都列出了*的可接收漏泄电流，而不是实际的电阻。例如，对于3线式手持电气用具 或工具来说，必须具有足够的绝缘，从外漏部分到地的的漏泄电流不得超过0.75 mA (0.00075 A)。

Although the standard insulation resistance technical indicators can be used in most motor and other electrical devices, the specific environment requires the use of more stringent resistance technical indicators. Most of the technical specifications give the largest acceptable leakage current, not the actual resistance. For example, there must be enough insulation for 3 line handheld electrical appliances or tools, and the leakage current from the leakage part to the ground must not exceed 0.75 mA (0.00075 A).

按照1 kV的工业标准，一般的电阻值要比 1 MQ髙出三分之一。被标称为“双绝缘” 的****和电气装置都具有比普通的设 备髙许多的绝缘等级。杂项设备包括双插 脚CAT II电源线设备、三插脚CAT I电 源线设备和干式变压器。YC橡套电缆

According to the industrial standard of 1 kV, the resistance value is 1/3 higher than that of 1 MQ. The medical equipment and electrical device, which is called "double insulation", has many insulation levels than ordinary equipment. Miscellaneous devices include dual pin CAT II power line equipment, three pin CAT I power line equipment and dry type transformer.

绝缘电阻值会随温度和绝缘材料中的水分量而变化。在读取绝缘测试读数时，应该记录温度和湿度。YC橡套电缆

The insulation resistance varies with temperature and the water content in the insulating material. When reading insulation test readings, temperature and humidity should be recorded.
