江蘇春晨電纜有限公司生產YC橡套電纜，雜項電氣裝置的排障

The barrier of miscellaneous electrical equipment

雜項設備包括便攜式電氣設備、雙絕緣工具、延長線、變壓器，以及通過獨立的電源線接收電力的電氣設備。對這些設備進行絕緣電阻測試是定期維護程序的一部 分，也是OSHA和NEC?標準的要求。

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.

在對大多數(shù)馬達和其它電氣裝置進行排障 時，盡管可以使用標準的絕緣電阻技術指標，但是特定的環(huán)境則要求使用更髙的電 阻技術指標。大多數(shù)給出的技術指標都列出了*的可接收漏泄電流，而不是實際的電阻。例如，對于3線式手持電氣用具 或工具來說，必須具有足夠的絕緣，從外漏部分到地的的漏泄電流不得超過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的工業(yè)標準，一般的電阻值要比 1 MQ髙出三分之一。被標稱為“雙絕緣” 的****和電氣裝置都具有比普通的設 備髙許多的絕緣等級。雜項設備包括雙插 腳CAT II電源線設備、三插腳CAT I電 源線設備和干式變壓器。YC橡套電纜

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.

絕緣電阻值會隨溫度和絕緣材料中的水分量而變化。在讀取絕緣測試讀數(shù)時，應該記錄溫度和濕度。YC橡套電纜

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.
