6GK1970-1BA10-0AA1 對比中性點接地與中性點不接地系統發生接地故障時的情況：6GK1970-5CA20-0AA1 1：中性點不接地系統 （1）發生碰殼接地故障時，若設備沒有接地，則設備外殼電壓上升為相電壓，人接觸后很危險。 （2）若設備接地了，則人接觸后，人體與設備接地并聯接地，可看出設備接地電阻越小，流過人體的電流越小。 （3）為限制流過人體的電流，必須控制設備外殼的接地電阻，一般小于4歐姆。 （4）漏電電流很小，不能快速跳閘。 （5）碰殼或單相接地后，其他兩相對地電壓升高為380V，可能燒壞220V設備。（三相相電壓繼續保持平衡）中性點沒有接地，漏電電流經過漏電電容回到電源，電流很小。 2：中性點接地系統 （1）無重復接地時，設備外殼電壓為短路電流形成的電壓降。 （2）重復接地時，重復接地處的接地電阻與電源的接地電阻串聯，起到分壓作用，降低外殼電壓。 （3）漏電電流很大，能快速跳閘。 （4）碰殼或單相接地后，其他兩相仍可接近相電壓，還可防止系統振蕩，電氣設備和線路只需按相電壓考慮其絕緣水平。 RDCO-02C 如果您需要訂購產品超過1件，請與我們聯系，我們可以為您提供折扣。6GK1970-5CA20-0AA1 *我們僅采用快遞方式遞送備件。（順豐） *如果您發現其他供貨商為相同產品提供更為低廉的價格，我們也愿意參照其價格向您提供進一步的折扣。 如果還有其他任何問題，請隨時與我們聯系。 *請讓我們知道您有任何，備品，備件，的需要，我們可以給您進一步的援助，我們等候您的詢盤。 ————————廈門光沃自動化設備有限公司——————————————— · ?person：小歐? · ?Mobile phone：18030229050 ? · ?Telephone：0592-5709821? · ?Fax：0592-5917519 · ?QQ:1878187406? · ?E-mail:1878187406@qq? 6GK1970-1BA10-0AA1
