1. Lichtbogenerkennung: Kernkonzepte und Prinzipien

1.1 Was ist ein Bogen?? Was ist Lichtbogenerkennung??

Ein Bogen In elektrischen Geräten bedeutet „plötzlich“., anhaltende Entladung von Elektrizität durch ionisierte Luft oder isolierende Medien, häufig durch Isolationsversagen verursacht, lose Verbindungen, oder Kontamination. Diese Entladung erzeugt starke Hitze, Licht, und manchmal klingen, Dies birgt erhebliche Gefahren für die Ausrüstung und das Personal.

Lichtbogenerkennung ist der Prozess von Identifizieren des Auftretens eines Lichtbogens so früh wie möglich, unter Verwendung einer Kombination aus Sensoren und Algorithmen. Ziel ist es, den fehlerhaften Abschnitt schnell zu isolieren, Minimieren Sie die freigesetzte Energie, und verhindern, dass es zu Bränden oder der Zerstörung von Geräten kommt. Lichtbogenerkennungssysteme sind heute ein wichtiger Bestandteil intelligenter Umspannwerke und Strategien zum Schutz digitaler Vermögenswerte.

1.2 Funktionsprinzip: Wie funktioniert die Lichtbogenerkennung??

Arc detection technologies are based on the physical signatures produced by an arc, einschließlich:

• Optical emission: The arc emits visible and ultraviolet light, which can be detected using photodiodes, optische Fasern, or imaging sensors.
• Thermal effects: Arcs cause a rapid local temperature increase, which can be sensed by fast-response temperature sensors or Fluoreszenzfaseroptische Temperatursensoren.
• Electrical signatures: Arcs produce characteristic current and voltage transients, as well as high-frequency noise, which can be identified using current transformers or pattern recognition algorithms.
• Akustische Emission: Some arcs generate sharp sound pulses that can be detected with piezoelectric microphones.

Modern arc detection solutions often combine several of these signals for higher reliability and faster response.

1.3 Technology Pathways: Optisch, Elektrisch, and Fiber-Based Detection

Erkennungsmethode	Prinzip	Vorteile	Einschränkungen
Optical Sensor	Detects visible/UV light from an arc	Schnell, selective, immun gegen EMI	May be affected by dust or enclosure design
Electrical Signature	Monitors current/voltage anomalies	Can detect hidden arcs, no line-of-sight needed	Susceptible to false alarms from switching events
Fluorescence Fiber Optic Temperature	Detects rapid hot spot temperature rise	Pinpoints pre-arc heating, immun gegen EMI	Best as a complement to arc detection
Akustisch	Detects sound pulses from arc	Berührungslos, schnell	May be affected by ambient noise

2. Applications of Arc Detection in Power Equipment

2.1 Arc Detection in Switchgear

Schaltanlage is especially susceptible to arc faults due to its high concentration of conductive parts, bewegliche Kontakte, and compact enclosures. Even a small arc can escalate into a major explosion, threatening lives and causing costly outages.

Arc detection systems in switchgear typically use a combination of optische Fasersensoren, photodiodes, Und Fluoreszenzfaseroptische Temperatursensoren placed near busbars, Kabelendverschlüsse, und Gelenke. Wenn ein Lichtbogenereignis erkannt wird, Das System löst eine schnelle Auslösung des Leistungsschalters aus – oft in weniger als 2 Millisekunden – um Schäden zu minimieren.

Die Integration von Fluoreszenzfaseroptische Temperatursensoren ermöglicht nicht nur die Erkennung von Lichtbögen, sondern auch deren laufende Überwachung Hot-Spot-Temperaturen an kritischen Stellen. Dieser duale Ansatz bedeutet, dass abnormale Erwärmung – oft ein Vorläufer eines Lichtbogens – frühzeitig erkannt werden kann, Dies ermöglicht eine vorbeugende Wartung, bevor ein gefährliches Ereignis eintritt.

• Fallbeispiel: In einem Rechenzentrum in Hongkong, Durch die Nachrüstung von Schaltanlagen mit Lichtbogenerkennung und Überwachung der Fluoreszenzfasertemperatur konnten ungeplante Ausfälle reduziert werden 85% und es wurden zwei Fälle abnormaler Sammelschienenerwärmung festgestellt, bevor Lichtbogenereignisse auftraten.

Lichtbogenerkennung in Schaltanlagen: Hauptvorteile

Besonderheit	Konventionelle Schaltanlagen	Mit Bogen & Überwachung der Fasertemperatur
Reaktion auf Lichtbogenfehler	Verzögert, oft nach Schäden	Sofort, minimiert Schäden
Hot-Spot-Erkennung	Manual/periodic	Echtzeit, kontinuierlich
Vorausschauende Wartung	Reaktiv	Proaktiv, risk-based
Personensicherheit	Beschränkt	Significant improvement

2.2 Arc Detection in Transformers

Transformatoren are critical assets in power systems, where an undetected arc event can result in catastrophic damage and prolonged outages. Arcs may occur inside the tank due to insulation breakdown, loose connections at bushings, or defects in tap changers. Traditional protection systems may not react quickly enough to prevent severe consequences.

Modern arc detection systems for transformers often combine optical arc sensors mit Fluoreszenzfaseroptische Temperatursensoren. The optical arc sensors detect the sudden burst of light from an arc, while the fiber temperature sensors continuously monitor Hot-Spot-Temperaturen in windings, führt, and tap changer compartments.

This dual-layer monitoring is especially valuable because many electrical faults are preceded by gradual overheating at a connection or insulation point. Fluoreszenzfasersensoren are immune to electromagnetic interference and can be safely deployed inside oil-filled or high-voltage environments. When abnormal temperature rises are detected, maintenance teams can intervene before an arc flash occurs, greatly reducing risk.

• Fallbeispiel: In a 220kV substation in Guangdong, the deployment of arc detection with fiber optic temperature monitoring reduced major transformer failures by 70% over five years. Incipient faults on tap changer contacts were detected as hot spots days before a disruptive arc could occur.

Transformer Arc Detection: Combined Approach

Detection Feature	Optical Arc Sensor	Fluorescence Fiber Temp Sensor	Combined System
Arc Flash Event	Ja	NEIN	Ja
Pre-Arc Hot Spot	NEIN	Ja	Ja
Reaktionsgeschwindigkeit	Millisekunden	Sekunden	Milliseconds/Seconds
Suitability for Oil-Filled Environment	Hoch	Sehr hoch	Sehr hoch

2.3 Arc Detection in Generators

Generatoren operate under high current and strong magnetic fields, making failures due to arc events particularly dangerous and expensive. Arc faults can occur in stator windings, Verbindungen, and terminal boxes, often initiated by insulation aging or mechanical vibration.

Arc detection systems for generators utilize optische Sensoren placed in terminal enclosures and around stator windings. For added reliability, Fluoreszenzfaseroptische Temperatursensoren are embedded in the stator and rotor slots, providing continuous temperature profiles of the most vulnerable points.

When a local hot spot is detected by the fiber sensors, it serves as an early warning of insulation breakdown or developing arc risk. If an arc occurs, the optical sensors instantly trigger shutdown or isolation, protecting both the machine and personnel. This layered approach is particularly effective in large hydro and thermal power plants, where generator downtime results in major revenue loss.

• Fallbeispiel: At a hydropower plant in Sichuan, a generator was retrofitted with arc detection and fiber temperature monitoring. The system detected abnormal heating in the stator before an arc developed, allowing planned maintenance and saving an estimated $500,000 in repair and outage costs.

Aspekt	Without Arc/Temp Monitoring	Mit Bogen & Fiber Temp Monitoring
Fehlererkennungsgeschwindigkeit	Verzögert	Immediate/Continuous
Maintenance Type	Breakdown	Condition-based
Repair Cost	Hoch	Reduziert
Generator Availability	Unpredictable	Optimiert

2.4 Integrated Application: Lichtbogenerkennung & Fluoreszenzfaser-Temperatursensoren

While arc detection systems provide immediate response to arc events, integrating them with Fluoreszenzfaseroptische Temperatursensoren enables a dual-layer protection strategy. This combined solution offers two key advantages:

• Vorwarnung: The temperature sensors detect abnormal heating trends at critical points, allowing maintenance teams to act before an arc develops.
• Rapid Fault Isolation: If an arc still occurs, the optical detection system triggers instantaneous breaker operation, minimizing damage and downtime.

This approach is now standard in leading digital substations, high-reliability transformer sites, and large generator stations, especially in regions such as Hong Kong, Singapur, and Western Europe.
