EDS460-D-1 具有控制和显示功能的绝缘故障定位器

产品描述
绝缘故障定位器ISOSCAN* EDS460/490结合ISOMETER*IRDH575或定位电流注入器PGH用于定位出土系统(IT系统)的绝缘故障。通过测量电流互感器检测绝缘监测装置IRDH575或定位电流注入器PGH产生的定位电流信号，并由绝缘故障定位器进行评估。多达12个测量电流互感器可以连接到一个EDS460/490。共90个EDS岛。故障定位器可通过1路Rs-485接口(BMS协议)连接。因此，可以监控多达1080个电路。最大扫描时间为…10 s，见TGH1394
应用程序
交流，交直流和DCIT系统的绝缘故障定位。工业厂房和船舶的主电路和控制电路。电站用二极管解耦dcitl系统*医疗场所系统
函数
绝缘故障定位通过ISOMETER* IRDH575或PGH手动或自动启动，一旦启动，绝缘故障定位仪EDS同时扫描所有测量电流互感器(通道)。如果存在多个EDS，这些设备也同时被扫描。
当测量电流互感器检测到的定位电流超过设定响应值时，报警LED 2亮起，普通报警继电器开关和故障电路在图形显示器上以明文形式显示。版本EDs……L通过报警led表示故障输出电路。连续监测测量电流互感器与绝缘故障定位器之间的连接。在电线中断的情况下，报警LED 1亮起，报警继电器开关。
故障记忆激活后，各个通道的报警信息一直保存到复位按钮被按下或通过r5 -485接口给出复位命令。故障内存关闭后，告警信息会一直保存到绝缘故障消除。
EDs460/461-D/ eds490 /491- d该设备利用历史存储器用于故障安全存储多达300个测量值/事件(日期，时间，通道，事件代码，测量值)，以便有关出线电路或区域的所有数据可以随时追溯到(何时发生的事情)。

Product description
The insulation fault locators ISOSCAN* EDS460/490 in combination with the ISOMETER*IRDH575 or the locating current injector PGH are applied for localising insulation faults inunearthed systems (IT systems). The locating current signals generated by the insulationmonitoring device IRDH575 or the locating current injector PGH are detected by measuring current transformers and evaluated by the insulation fault locators. Up to 12 measuring current transformers can be connected to one EDS460/490. A total of 90 EDS insula.tion fault locators can be connected via one Rs-485 interface (BMS protocol). Hence, upto 1080 circuits can be monitored. The maximum scanning time is …10 s, see TGH1394
Application
.Insulation fault location in AC, AC/Dc and DCIT systems.Main and control circuits in industrial plants and ships.Diode-decoupled DCITsystems in power stations*Systems for medical locations
Function
Insulation fault location is started manually or automatically via the ISOMETER* IRDH575 Orthe PGH, Once started, the insulation fault locator EDS simultaneously scans all measuringcurrent transformers (channels). lf several EDS exist, these devices are also scanned simultaneously.
When the locating current detected by a measuring current transformer exceeds the setresponse value, the alarm LED 2 lights up, the common alarm relay switches and the faultycircuit is indicated as plain text on the graphical display. Version EDs…L indicates faultyoutgoing circuits via alarm LEDs. The connection between the measuring current transformerand the insulation fault locator is continuously monitored. in the event of wire interruptionthe alarm LED 1 lights up and the alarm relay switches.
With the fault memory activated, the alarm messages of the individual channels remainsstored until the reset button is pressed or until a reset command is given via the R5-485interface. When the fault memory is deactivated, the alarm message remains stored untilthe insulation fault is eliminated.
History memoryin EDs460/461-D/EDS490/491-DThe device utilises a history memory for failsafe storing of up to 300 measured values/events (date, time, channel, event code, measured value), so that all data about an outgoingcircuit or an area can be traced back at any time (what happend when).
