What is the best temperature monitoring technology for medium voltage switchgear-INNO

Mengapa alat suis Asia Tengah memerlukan pengukuran suhu

Dengan perkembangan ekonomi negara, permintaan terhadap tenaga elektrik dalam pelbagai industri semakin meningkat. Suhu titik sentuhan di dalam suis voltan tinggi di loji janakuasa dan pencawang meningkat dengan peningkatan arus. Jika suhu titik sentuhan di dalam suis voltan tinggi terus meningkat, ia akan menyebabkan suhu titik sentuhan di dalam suis voltan tinggi menjadi terlalu panas, membawa kepada kemalangan terlampau panas pada suhu suis dan mengakibatkan kebakaran dan gangguan kuasa besar-besaran. Itu, beban kerja memantau operasi selamat peralatan elektrik dalam sistem kuasa semakin meningkat dengan cepat. Operasi unit dalam loji janakuasa dan pencawang tidak bebas antara satu sama lain, but requires the coordination of various links in order to work safely, effectively, and reliably. The power supply of electrical equipment is mostly achieved through switchgear groups for transmission and distribution. If one of the switchgear fails, it will inevitably affect the operation of the entire substation or substation. Berdasarkan ini, as the main parameter for the safe operation of electrical equipment in the power system, the monitoring task of the contact temperature of high-voltage switchgear in substations is becoming increasingly heavy.

Kelemahan termometer inframerah untuk suis

Excessive temperature of power equipment will directly affect its reliability. If not detected and controlled in a timely manner, the severity of overheating will have a significant impact on the performance of insulation materials and equipment life. Peralatan voltan rendah, due to its low voltage level, typically has a higher current and higher temperature compared to high voltage equipment. In the hot summer, higher environmental temperatures and higher loads are likely to cause a sudden increase in the temperature of low-voltage equipment, leading to equipment aging, degradasi penebat, dan dalam kes yang teruk, kerosakan peralatan, litar pintas, and ultimately power outages. Pada masa ini, all public distribution rooms operate in an unmanned manner, and operators only use infrared thermometers to measure the temperature of the internal busbar and outlet cable heads of the low-voltage cabinet during regular inspections. They cannot monitor equipment temperature in real time online and cannot detect safety hazards of the equipment. Dalam beberapa tahun kebelakangan ini, beberapa syarikat kuasa telah mula mencuba pengukuran suhu dalam talian bagi peralatan voltan tinggi dalam rangkaian pengedaran. Sebenarnya, dalam operasi sebenar rangkaian pengedaran, terdapat lebih banyak kegagalan peralatan yang disebabkan oleh suhu peralatan yang tinggi dalam rangkaian voltan rendah berbanding rangkaian voltan sederhana.

Keperluan peranti pemantauan untuk suis voltan sederhana

Alat suis voltan sederhana adalah peralatan elektrik yang penting dalam sistem penghantaran. Arus luaran memasuki suis kawalan utama di dalam kabinet melalui wayar, dan kemudian masukkan suis sub kawalan untuk menyambung dengan setiap cawangan; Setiap cawangan perlu dilengkapi dengan instrumen, komponen kawalan dan perlindungan, komponen pemantauan, pelbagai pemutus litar AC dan komponen kawalan lain untuk dikawal, melindungi, mengukur, mengukur, dan memantau litar.

Apabila masa penggunaan meningkat, status pengendalian suis akan beransur-ansur merosot, dan pelbagai tanda-tanda kerosakan akan beransur-ansur muncul; Sebagai contoh, sambungan konduktif di dalam suis mungkin merosot keadaan sentuhan akibat haus elektrik, getaran mekanikal, dan kecacatan tersembunyi dalam proses pembuatan peralatan, menyebabkan peningkatan suhu titik sentuhan. Peningkatan suhu akan memperhebatkan lagi pengoksidaan permukaan sentuhan, membentuk kitaran ganas sehingga kerosakan penebat berlaku, akhirnya membawa kepada pelepasan arka dan kemalangan peralatan. Komponen penebat di dalam kabinet, disebabkan pendedahan jangka panjang kepada voltan tinggi dan medan elektromagnet yang kuat, juga boleh menyebabkan penuaan penebat dan habuk permukaan, akhirnya membawa kepada penurunan prestasi penebat dan menyebabkan kemalangan. The circuit breaker, due to being in operation for a long time without action, causes a decrease in the lubrication function of the moving parts of the operating mechanism, changes in mechanical characteristics, and affects the ability to open and close normal or fault currents, which can lead to accidents in severe cases.

Fluorescent fiber optic temperature measurement technology for switchgear

Fiber optic technology has its unique physical characteristics. The unique physical characteristics of fiber optic sensors are manifested in their fine diameter, Rintangan terhadap gangguan elektromagnet, Kakisan, rintangan suhu tinggi, and signal attenuation ratio, ringan, and the integration of information sensing and transmission. They can effectively solve measurement problems that cannot be solved by conventional detection technologies. Fiber optic itself is a good insulation material, which can isolate the high voltage between the power system and electrical temperature measurement equipment, avoiding electrical equipment safety accidents caused by temperature measurement devices. Sementara itu, fiber optic devices are also excellent carriers for transmitting and sensing signals, solving the problem of electromagnetic interference in data transmission in the power system environment, making measurement results more accurate and reliable. Selain itu, due to the small diameter, Berat ringan, and good flexibility of optical fibers, they can detect areas that ordinary sensors cannot detect. Fiber optic has these advantages, making fiber optic sensors increasingly widely used in online temperature measurement of electrical equipment in power systems. FJINNO’s independently developed switch cabinet sistem pengukuran suhu optik optik is the most important temperature measurement technology for online temperature measurement of electrical equipment in high, sederhana, and low voltage switch cabinets.
