Temperatuurbewakingssysteem voor luchtschakelapparatuur

Air switchgear, as a key equipment in the power system, its operating status is directly related to the stability and reliability of power supply. Abnormal temperatures at internal contacts, busbar connections and other parts are often important factors causing faults. The fluorescent fiber optic temperature monitoring system, met zijn unieke voordelen, has become a powerful assistant in ensuring the safe operation of air switchgear.

1. Working Principle of Fluorescent Fiber Optic Temperature Monitoring System

A fluorescent substance is plated on the end of the optical fiber. When excited by light of a specific wavelength, the fluorescent substance radiates fluorescent energy. Since the excited radiation energy decays exponentially, and the decay time constant changes with temperature, de temperatuur op het meetpunt kan worden verkregen door de vervaltijd nauwkeurig te meten. Deze temperatuurmeetmethode op basis van het fluorescentie-effect biedt een betrouwbaar technisch pad voor temperatuurmonitoring in luchtschakelapparatuur.

2. Kenmerken van het fluorescerende glasvezeltemperatuurbewakingssysteem

Kenmerken	Details
Sterk anti-elektromagnetisch interferentievermogen	Fluorescerende glasvezelsensoren maken gebruik van diëlektrische weerstandsmaterialen, die volledig vrij zijn van elektromagnetische interferentie (EMI) en radiofrequentie-interferentie (RFI). Ze kunnen stabiel werken in de sterke elektromagnetische omgeving in de luchtschakelapparatuur, zorgen voor een nauwkeurige verzameling en verzending van temperatuurgegevens.
Uitstekende isolatieprestaties	De sensor zelf is een volledig optisch meetapparaat met alleen optische signalen en geen elektrische signalen, een werkelijk passieve sonde zijn. In de 30cm grondisolatietest, it can withstand 140kV power frequency voltage, far exceeding the national standard, which can effectively avoid safety hazards caused by electrical connections and is suitable for the high-voltage environment of air switchgear.
Uiterst nauwkeurige temperatuurmeting	The temperature measurement accuracy can reach ±1℃, and the resolution is 0.1℃, which can敏锐ly capture subtle temperature changes inside the air switchgear and timely detect potential fault hazards.
Snelle reactie	De temperatuurmeetcyclus is korter dan 1 tweede, and the standard temperature measurement response time is 0.5 Seconden, which can fully ensure the timeliness of alarms. Once the temperature is abnormal, it can respond quickly, striving for valuable time for fault handling.
Compact formaat	The temperature-sensing probe is small in size (3Mm), which is convenient for accurate positioning and installation in the narrow space inside the air switchgear, and has little impact on the original structure and performance of the equipment.
Long service life and stability	The temperature-sensing material uses rare earth materials, with long-term stable performance. It has been successfully applied in equipment monitoring for more than 30 jaren. The service life of the light source is lifelong. The system has high stability, and each temperature measurement unit is independent of each other, so the failure of a single link will not cause the entire system to fail.

3. Veelgestelde vragen (FAQ) about Fluorescent Fiber Optic Temperature Monitoring System

(1) Installatie-aspect

1. Q: Is the installation of the fluorescent fiber optic temperature monitoring system complicated?
   Een: The system installation is relatively convenient. The temperature-sensing probe is small in size and can be installed at key temperature measurement points of the air switchgear, such as moving and static contacts and busbar joints, by means of tape binding, clip fixing, thread fixing, gluing, enz. The analyzer and other equipment also have various installation forms to choose from, such as industrial standard DIN rail installation, ordinary desktop installation, enz. Op hetzelfde moment, the optical fiber wiring is relatively flexible and can be reasonably arranged according to the on-site environment.
2. Q: Will the installation process affect the normal operation of the air switchgear?
   Een: As long as the correct operating procedures are followed during installation, it will not affect the normal operation of the air switchgear. Since the fluorescent fiber optic sensor is a passive probe, there is no need for large-scale electrical transformation of the switchgear during installation, and some installation operations can be carried out in the charged state. Echter, it is necessary to take protective measures to ensure the safety of installers.

(2) Usage and Maintenance Aspect

1. Q: Does the system need regular calibration during use?
   Een: The sensor of the fluorescent fiber optic temperature monitoring system is not restricted by channel interchangeability, and can achieve accurate temperature measurement without frequent calibration after installation. Its internal optical sensing technology avoids the influence of drift which traditional electronic components are prone to, and has good long-term stability in use, which can greatly reduce the maintenance frequency.
2. Q: If the optical fiber sensor is damaged, is it troublesome to replace?
   Een: Replacing a damaged optical fiber sensor is relatively cumbersome. Because the optical fiber sensor of each channel is matched one-to-one with the channel of the temperature demodulator, and each channel cannot be interchanged, it is necessary for the manufacturer to separately produce an optical fiber sensor that has been set and calibrated for installation and use. Daarom, in daily use, attention should be paid to the protection of the optical fiber sensor to reduce the risk of damage.
3. Q: What is the approximate service life of the system?
   Een: The overall service life of the system is relatively long. The rare earth material used as the temperature-sensing material has stable performance. The service life of the light source is lifelong. Onder normale omstandigheden, the system can operate stably for more than 10 jaren, reducing the cost and inconvenience caused by frequent replacement of equipment.

(3) Performance Aspect

1. Q: Will the measurement accuracy of the system be affected in high-temperature environments?
   Een: The fluorescent fiber optic temperature monitoring system is designed to be suitable for a wide temperature range. Within the temperature measurement range of -30℃~150℃, it can maintain high-precision measurement of ±1℃. Even in the high-temperature environment that may occur inside the air switchgear, it can reliably provide accurate temperature data.
2. Q: Can the system monitor the temperature of multiple points at the same time?
   Een: Ja. The system supports multi-channel monitoring. According to the monitoring needs of the air switchgear, multiple temperature-sensing probes can be flexibly configured to monitor the temperature of multiple key parts in real time, so as to fully grasp the temperature status of the equipment.
