IRDH275B-435 系統(tǒng)接地指示燈和蜂鳴器同時(shí)告警

IRDH275-435是應(yīng)用于主回路的絕緣監(jiān)測(cè)儀。 可監(jiān)測(cè)的電壓范圍為AC,3(N)AC,AC/DC0-793V或DC0-650V。 它的原理是安倍測(cè)試法，這種測(cè)試法符合現(xiàn)代的電源系統(tǒng)，比如常見的整流器，變流器，可控硅控制等直流驅(qū)動(dòng)，他也可以直接和直流元器件連接。
絕緣監(jiān)測(cè)儀是一種針對(duì)直流電源系統(tǒng)母線及支路的絕緣狀態(tài)進(jìn)行在線實(shí)時(shí)監(jiān)測(cè)與管理的裝置。該裝置主要應(yīng)用于監(jiān)測(cè)直流電源系統(tǒng)的母線及各支路的絕緣狀況，當(dāng)發(fā)生絕緣降低或接地故障時(shí)，絕緣監(jiān)測(cè)儀能及時(shí)發(fā)出告警信息，并準(zhǔn)確地將故障點(diǎn)及類型送到主機(jī)，通知相關(guān)人員及時(shí)排查故障，有效避免事故的發(fā)生。

絕緣監(jiān)測(cè)儀采用高精度智能直流漏電流傳感器進(jìn)行支路漏電流檢測(cè)，測(cè)量準(zhǔn)確及時(shí)。其主機(jī)實(shí)時(shí)監(jiān)控系統(tǒng)母線對(duì)地阻抗，包括正對(duì)地電阻，負(fù)對(duì)地電阻并實(shí)時(shí)顯示。當(dāng)直流系統(tǒng)發(fā)生故障，正負(fù)對(duì)地電壓不再平衡并超過預(yù)設(shè)整定值時(shí)，主機(jī)液晶屏顯示告警信息，系統(tǒng)接地指示燈和蜂鳴器同時(shí)告警。

此外，絕緣監(jiān)測(cè)儀還可以通過檢測(cè)未接地回路的對(duì)地阻抗判斷其長(zhǎng)期變化的趨勢(shì)，提供回路接地的預(yù)警信息。絕緣降低預(yù)警和環(huán)路匹配監(jiān)測(cè)為系統(tǒng)的診斷提供了有效手段。

絕緣監(jiān)測(cè)儀安規(guī)和EMC符合CE認(rèn)證，已廣泛應(yīng)用于各類容量的電力操作電源系統(tǒng)的絕緣狀態(tài)監(jiān)測(cè)與管理中，并可廣泛應(yīng)用于醫(yī)療、電信、冶金、煤礦、船舶、建筑機(jī)械、石油化工及交通工程等領(lǐng)域。

IRDH275-435 is an insulation monitor for use in the main circuit. The voltage range that can be monitored is AC,3(N)AC,AC/DC0-793V or DC0-650V. Its principle is the Abe test method, this test method conforms to modern power systems, such as common rectifiers, converters, thyristor control and other DC drives, he can also be directly connected with DC components.
The insulation monitor is a device which can monitor and manage the insulation status of the bus and branch of DC power system in real time. The device is mainly used to monitor the insulation status of the bus bar and branches of the DC power system. When the insulation reduction or grounding fault occurs, the insulation monitor can send alarm information in time, and accurately send the fault point and type to the host, so as to notify the relevant personnel to troubleshoot the fault in time and effectively avoid the occurrence of accidents.

The insulation monitor uses high-precision intelligent DC leakage current sensor to detect the branch leakage current, and the measurement is accurate and timely. The host monitors the bus impedance of the system to the ground in real time, including the positive resistance to the ground, the negative resistance to the ground and displays it in real time. When the DC system is faulty and the positive and negative voltage to ground is unbalanced and exceeds the preset setting value, the host LCD displays an alarm, and the system ground indicator and the buzzer both generate alarms.

In addition, the insulation monitor can also detect the long-term change trend of the ground impedance of the ungrounded circuit and provide the early warning information of the grounding of the circuit. Insulation reduction early warning and loop matching monitoring provide effective means for system diagnosis.

Insulation monitor safety and EMC compliance with CE certification, has been widely used in various capacity of power operation power system insulation status monitoring and management, and can be widely used in medical, telecommunications, metallurgy, coal mine, shipbuilding, construction machinery, petrochemical and traffic engineering and other fields.
