How to use fiber optic temperature sensors to monitor hotspots in switchgear/ring main unit

Using a Système de mesure de température par fibre optique fluorescente, 24-hour real-time online monitoring of hotspots such as contacts, busbars, and cable joints in high-voltage cabinets/ring main units is carried out to grasp the temperature of hotspots in the ring main units in real time and accurately locate hotspots. Choose a customized fluorescent fiber optic temperature sensing probe that can directly contact the hot spot.

Le Système de mesure de température par fibre optique à fluorescence is mainly used for real-time online monitoring of abnormal temperature changes in the internal contacts and contacts of high-voltage switchgear/ring main unit in substations. With the help of this system, users can monitor the temperature changes of key parts inside high-voltage switchgear/ring main unit in real time on local and remote upper computers, and issue real-time alarm information (warning, alarm, and over limit) based on the temperature changes.

Using a Système de mesure de température par fibre optique fluorescente to conduct real-time online monitoring of the cable plugs in the ring main unit 24 hours a day, comprehensively grasp the temperature morphology of the cable plugs in the ring main unit, and accurately locate the hotspots of the plugs. The fluorescent fiber thermometer is connected to the fluorescent temperature probe through a connector. The fiber connector embedded in the silicone sheath can directly contact the wire inside the cable plug, which can detect the most accurate temperature of the connector. With the help of this system, users can monitor the temperature changes of the ring main unit cable plugs in real time on local and remote upper computers, and issue real-time alarm information (warning, alarm, and over limit) based on the temperature changes.

Le temperature measuring fiber (including the temperature measuring probe) converts the temperature information of the monitoring part of the temperature measuring probe into an optical signal and transmits it to the fluorescent fiber temperature measurement demodulation and alarm module. The probe size of the fiber optic sensor is extremely small and can be directly installed on the measured point for accurate temperature measurement and rapid response; The tail fiber is made of soft and sturdy specially designed optical fibers, which have the advantages of high transmission bandwidth, stable signal, anti-interférences électromagnétiques, anti bending, high impact strength, and fast connection; The material of the tail fiber sheath is polytetrafluoroethylene, which has the characteristics of high temperature resistance, résistance au vieillissement, résistance à la corrosion, haute isolation, and non adhesion. It can adapt to harsh environments such as high voltage, haute température, and strong electromagnetic fields.

Le Capteur de température à fibre optique is embedded in the insulation plug of the T-joint of the ring main unit. The fiber optic sensor directly contacts the metal part at the tail of the plug to monitor the temperature inside the T-joint in real time;

Le capteur à fibre optique est intégré à l’intérieur du produit lors du versement de la prise, fully embedded with the plug, without changing the original shape of the plug and cable head, et sans réduire les performances de la tête de câble et de l’ensemble de l’armoire;

The plug and the whole machine can pass partial discharge test and withstand voltage test normally after pre setting the fiber optic sensor;

Capteurs à fibre optique have good flexibility, dureté physique élevée, ne sont pas facilement endommagés, et avoir une longue durée de vie;

Sensors can be customized according to requirements, including sensor length, Type de sonde, and sensor sheath material (céramique, verre, plastic, or other insulating materials);

Most fire accidents in switchgear/ring main units are caused by high temperatures. Donc, timely and accurate monitoring of temperature changes in switchgear/ring main units and issuing warnings before a fire occurs is particularly important for users to have sufficient time to take corresponding measures to avoid accidents or fires. Fluorescence temperature sensing technology has the advantages of high voltage resistance, immunity to electromagnetic interference, Sécurité intrinsèque, long-term reliability, and easy scalability. It can perform real-time online monitoring of the temperature of switchgear/ring main unit joints and contacts.
