IRDH575 ISOnet功能用于多台IRDH575互连时绝缘监测过程的集中控制 IT系统

详情介绍:IRDH575 ISOnet功能用于多台IRDH575互连时绝缘监测过程的集中控制 IT系统

“someter”可以与iT系统断开连接，并通过功能输入F1/F2设置为standby模式。当输入F1/F2桥接时，ter。终端L1/L2通过内部耦合继电器与测量电路隔离，终端L3仍然通过10 MΩ的电阻连接到测量电路。测量功能停止，显示屏显示待机信息。当使用1.4或更高版本的软件时，最新测量的绝缘电阻将被清空，显示值> 10 MΩ。此外，报警继电器和报警led不再提供报警信息。已经检测到的绝缘故障将由allED54…设备指示。
打开功能输入F1/F2后，首先连接到lT系统。使用此功能，可以通过相应耦合开关的辅助触点选择性地断开互连IT系统中的IRDH575，每个线型或环型配置的耦合开关可以停用后续的IRDH575。这个安排。ment保证在每个电连接的IT系统中只有一个lSOMETER*是活跃的。
从理论上讲，在所有耦合开关关闭的环形布置中，所有的l$OMETER都将停止工作。为了防止这种情况，BMSMaster (lRDH575 Adr1)监视所有从ISOMETER*S的功能输入F1/F2的状态。当所有Slave lSOMETER*s都处于$TANDBY模式时，绝缘监控。Master的“lSOMETER”的ring函数保持活动状态，即Master的inputF1/F2在此模式下没有作用。

设在上述环形布置中，从机lSOMETER”2的关联耦合开关处于打开状态。BMS主服务器(地址1)和从服务器3和4的耦合开关关闭。在这种情况下，主服务器和从服务器3和4的lSOMETER*和EDS函数将被停用。尽管更改为待机模式，地址为1的设备的主状态将保持不变。这意味着，如果是一个参数。必须通过BMSaddress为1的lRDH575进行。

The lSOMETER” can be disconnected from the iT system and set to STANDBYmode with the function input F1/F2.When the input F1/F2 is bridged, the ter.minals L1/L2 are isolated from the measuring circuit via internal coupling relays and terminal L3 remains connected to the measuring circuit via a resistorof 10 MΩ. The measuring function is stopped and the message STANDBY appears on the display. When using software version 1.4 or higher, the latestmeasured insulation resistance is blanked and the value > 10 MΩ appears onthe display. Furthermore, the alarm relays and alarm LEDs no longer providealarm messages.Insulation faults already detected will be indicated by allED54…devices.
After opening the function input F1/F2, first ofall the connection to the lT sys.tem will be restored and a completely new measuring cycle for insulation monitoring will be started, Using this function, selective disconnection of anIRDH575 in interconnected IT systems can be carried out via auxiliary contactsof the respective coupling switch, One coupling switch each in a line type orring-type arrangement can deactivate a subsequent IRDH575.This arrange.ment guarantees that only one lSOMETER* is active in each galvanically con.nected IT system.
Theoretically speaking, in a ring-type arrangement with all coupling switchesclosed, all l$OMETER’s would be deactivated. In order to prevent this, a BMSMaster (lRDH575 Adr1) monitors the condition of the function input F1/F2 ofall Slave ISOMETER*S.When all Slave lSOMETER*s are in the $TANDBY mode, the insulation monito.ring function of the Master lSOMETER” remains active, that means, the inputF1/F2 of the Master is without function in this mode.

Let as assume, in the before-mentioned ring-type arrangement, the associa-ted coupling switch of the Slave lSOMETER” 2 were open. The coupling swit-ches ofthe BMS Master (Addr. 1) and ofthe Slaves 3 and 4 were closed. In thiscase the lSOMETER* and EDS functions of the Master and the Slaves 3 and 4would be deactivated. in spite ofchanging to the STANDBY mode, the Masterstatus ofthe device with address 1 would remain.That means, if a paramete.rization is necessary, it has to be carried out via the lRDH575 with BMSaddress 1.
