With the development of the economy and society, the demand for electricity in solid ring main unit temperature measurement continues to grow rapidly, and the scale of the distribution system continues to expand. The importance of safe operation of its distribution equipment is increasingly prominent, and scientific and efficient management is urgently needed. Solid ring main unit (RMU) is a distribution equipment that has gradually gained widespread attention and use in recent years. RMU is a type of RMU that uses solid insulation materials as the main insulation medium. The main conductive circuit of the vacuum arc extinguishing chamber and its conductive connections, isolation switches, grounding switches, main busbars, branch busbars, etc. are single or combined and encapsulated with solid insulation medium to form one or several modules with certain functions, which can be recombined or expanded and have full insulation and sealing performance. The surface of modules that can be touched by humans is coated with a conductive or semi conductive shielding layer and can be reliably grounded directly. Solid state ring main unit has the advantages of small volume, non-toxic, simple structure, pollution-free, and green environmental protection, which is in line with the global concept of green product development.

Solid State Ring Main Unit is an upgraded product of the current mainstream ring main unit. Maererano nenhamba, the number of new solid ring main units put into operation each year will reach 200000.
State Grid Corporation of China pointed out that from the development trend of stricter technical reliability and environmental protection requirements, solid insulated ring main units have the trend of completely replacing SF6 gas insulated ring main units. With the large-scale application of solid ring main units, online monitoring of solid ring main units is of great significance for the safe and reliable operation of power distribution systems. Mumakore achangopfuura, insulation faults and temperature rise faults have been ranked among the top three faults in the distribution voltage level of China’s power system. Naizvozvo, it is very important to monitor the insulation status of the solid ring main unit and the temperature rise of the busbar.

The application of fluorescent fiber optic temperature sensors in the field of smart grids:
1. Temperature monitoring of power transformer windings;
2. High voltage switchgear: It can measure the temperature at the junction of the plum blossom contact and the static contact in the switchgear, and can even be buried in the conductive connection of the insulation cylinder;
3. Temperature measurement of high-voltage circuit breaker arc extinguishing chamber;
4. Temperature monitoring of the stator, bearing shells, and end collector rings of large motors;
5. Directly monitor the hot spot temperature of high-voltage equipment such as large motors/transformer windings;
6. Real time online monitoring of temperature for other electrical equipment.
As one of the future development directions of fiber optic tembiricha sensors, fluorescent fiber optic temperature sensors for smart grids also have the following advantages:
1. Immune to electromagnetic, radio frequency, and microwave;
2. No metal components, no magnetization;
3. High measurement accuracy and good stability;
4. Good reliability and repeatability;
5. Tight structure and long service life;
6. No calibration required.
Due to the unparalleled advantages of fiber optic temperature sensors compared to traditional temperature sensors, with the increasing maturity of fiber optic temperature sensor technology, the establishment of technical regulations and related standards, fluorescent fiber optic temperature sensors will gradually replace traditional temperature sensors and become one of the most important means of power grid temperature monitoring.
