Mfumo wa kipimo cha joto cha nyuzi macho kwa baraza la mawaziri la kurekebisha

Function of fiber optic temperature measurement system for rectifier cabinet

1. The on-site temperature measurement device collects real-time temperature information of the switchgear contacts, nyaya, and voltage transformer coils. The use of fluorescent fiber optic temperature probes has extremely strong electromagnetic immunity, upinzani wa voltage, na utendaji wa insulation. Hisia nyeti ya halijoto, stable and reliable long-term operation. Usahihi wa kipimo cha joto unaweza kufikia ± 1 ℃.

2. The system comes with sound and light alarms, pato la mawasiliano kavu, and human-machine interface display of alarm information.

3. The backend monitoring software system displays real-time temperature information of each contact point in the current switchgear, real-time curves, and historical data storing temperature information of each contact point in the past month.

Kutumia njia mbalimbali za uchunguzi kuchambua hali ya afya ya vifaa, including analysis of all equipment parameter out of limit alarms and other judgment methods, to timely monitor the operation status of high-voltage switchgear. The system can automatically and manually generate various periodic reports, which can be exported and printed. Ripoti zilizosafirishwa zinaweza kuhaririwa na kutazamwa kupitia programu ya Excel. Wakati huo huo, mfumo una vitendaji vya maonyesho ya muda halisi na ya kihistoria ya halijoto, which can accurately reflect the real-time monitoring curve and the temperature change curve of the monitored object at a certain point during a certain period of time;

4. Detect temperature abnormality alarm

Over threshold alarm: When the temperature value is detected to exceed the threshold, an alarm can be triggered, and two levels of thresholds can be set;
Exceeding temperature difference alarm: If the temperature difference between the highest and lowest temperatures within a certain range of test points exceeds the set value (kizingiti kinaweza kuwekwa), the alarm will be triggered;

Kengele ya mabadiliko ya kiwango cha joto: Ikiwa mabadiliko ya joto yanazidi thamani iliyowekwa (threshold 19 can be set) ndani ya muda fulani, the alarm will be triggered;

mfumo fault alarm: The system monitors the performance status of the fiber optic temperature measurement probe and the connection status of the fiber optic, anatambua kujitambua na kupima, na kuamsha hitilafu za mfumo mara moja;

5. Detect temperature anomalies, system failures, nk., and the system will automatically alarm to achieve unmanned monitoring.
