2.產(chǎn) 品 詳 情 資 料：
RELIANCE S-D4006-D測試所有輸入和輸出的接地故障當(dāng)測試外部電纜的絕緣電阻、短路和電線斷裂時(shí)，必須斷開電纜的兩端，以避免用過高的電壓損壞或損壞模塊。斷開傳感器和控制元件的自由接頭后，進(jìn)行接地故障測試。電位分配器上的自由接頭的電壓連接也必須斷開，RELIANCE S-D4006-D負(fù)極必須在控制元件處分離。如果負(fù)極設(shè)置為接地操作，則在測試接地故障時(shí)必須中斷接地連接。這也適用于可能存在的接地故障測試設(shè)施的接地連接。任何連接都可以使用歐姆表或?qū)Ｓ脺y試設(shè)備進(jìn)行接地測試。注：在這種狀態(tài)下，如果單獨(dú)的線路或一組線路對地絕緣，則系統(tǒng)將進(jìn)行測試，但如果兩條線路彼此絕緣，則不進(jìn)行測試。否則有損壞的風(fēng)險(xiǎn)。
Testing All Inputs and Outputs for Earth Faults When testing the external cables for insulating resistance, short circuits and wire breaks, the cables must be disconnected at both ends in order to avoid damaging or destroying the modules with excessive voltage.RELIANCE S-D4006-DThe testing for earth faults is carried out after the disconnection of the free connectors for the sensors and control elements. The voltage connections of the free connectors on the potential distributors must also be disconnected, and the negative pole must be separated at the control elements. If the negative pole is set up for earthed operation, the earth connection must be interrupted while testing for earth faults. This also applies for the earth connection of possibly existing earth fault testing facilities.Any connection can be tested to earth with an ohmmeter or a special testing device. Note: In this state the system is set up for testing if individual lines or a group of lines are insulated against earth, but not if two lines are insulated against each other. Otherwise there is a risk of damage.RELIANCE S-D4006-D
