There are numerous high-voltage switchgear and ring main unit cabinets, which are widely used in practical applications and are important components and control points of urban power supply networks. The operation status of high-voltage switchgear/ring main unit directly affects the reliability of urban power supply system. The space inside the high-voltage switchgear/ring main unit is relatively small. If the equipment operates under overload for a long time, the ambient temperature and electrical contact temperature are prone to be high. If not detected and handled in a timely manner, it may lead to fire or explosion accidents. To ensure safe operation, many power maintenance personnel in companies need to regularly conduct manual temperature inspections on the high-voltage switchgear/ring main unit, which requires a large workload and low accuracy.

Disadvantages of manual inspection of high-voltage switchgear and ring main unit

1. Manual detection, unable to locate

The internal heat source of the high-voltage switchgear/ring main unit does not have an automatic positioning function, making it difficult to accurately locate accidents.

2. Closed space and difficult monitoring

The interior of high-voltage switchgear/ring main unit mostly adopts a closed structure, which has poor heat dissipation conditions and is prone to temperature rise, causing equipment failures. ntxiv thiab, it is not easy to detect in the early stage of ignition and develops rapidly after generating an open flame, making firefighting difficult.

The Solution of Fluorescent Fiber Optic Temperature Measurement System in High Voltage Switch Cabinet Ring Main Cabinet

Using a fluorescent fiber optic temperature measurement system to monitor the abnormal temperature changes of the contacts or internal contacts and contacts of the high-voltage switchgear/ring main unit in real-time 24 hours a day, comprehensively grasp the real-time temperature status of the contacts or contacts of the high-voltage switchgear/ring main unit, and accurately locate the hot spot position of the contacts or contacts. Fluorescent fiber optic temperature sensing probe uses customized materials to closely adhere to the contact or contact surface for accurate temperature monitoring. Real time alarm information (warning, alarm, and over limit) is issued based on temperature changes and pre-set temperature conditions.

Qhov no fiber optic kub ntsuas ntaus ntawv converts the temperature information monitored by the fluorescence temperature measurement probe into optical signals and transmits them to the fluorescence fiber optic temperature measurement demodulation and alarm module. The probe size of the fiber optic sensor is extremely small, and it 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 made optical fibers, which have the advantages of high transmission bandwidth, stable signal, electromagnetic cuam tshuam, anti bending, high impact strength, and fast connection; It has characteristics such as high temperature resistance, aging resistance, corrosion kuj, high insulation, and non adhesion, and can adapt to harsh usage environments such as high voltage, high temperature, and strong electromagnetic.
