Օպտիկամանրաթելային ջերմաստիճանի ցուցիչ, Խելացի մոնիտորինգի համակարգ, Տարածված օպտիկամանրաթելային արտադրող Չինաստանում

Using a fluorescent fiber optic temperature measurement system, 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.

Այն fluorescence fiber optic temperature measurement system 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 fluorescent fiber optic temperature measurement system 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.

Այն 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, հակաէլեկտրամագնիսական միջամտություն, 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, aging resistance, կոռոզիոն դիմադրություն, high insulation, and non adhesion. It can adapt to harsh environments such as high voltage, high temperature, and strong electromagnetic fields.

Այն fiber optic temperature sensor 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;

The fiber optic sensor is embedded inside the product during the pouring of the plug, fully embedded with the plug, without changing the original shape of the plug and cable head, and without reducing the performance of the cable head and the entire cabinet;

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

Օպտիկամանրաթելային սենսորներ have good flexibility, high physical hardness, are not easily damaged, and have a long service life;

Sensors can be customized according to requirements, including sensor length, probe type, and sensor sheath material (ceramic, glass, plastic, or other insulating materials);

Most fire accidents in switchgear/ring main units are caused by high temperatures. Հետեւաբար, 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, անձեռնմխելիություն էլեկտրամագնիսական միջամտության նկատմամբ, ներքին անվտանգություն, long-term reliability, and easy scalability. It can perform real-time online monitoring of the temperature of switchgear/ring main unit joints and contacts.
