Kelebihan menggunakan penderia suhu gentian optik pendarfluor untuk pemantauan suhu kabinet elektrik-INNO

Electrical cabinets are mainly used in the process of power generation, penularan, pengedaran, and energy conversion in the power system, as well as to control and protect electrical equipment. The components inside the electrical cabinet mainly consist of control components, penukar frekuensi, pemutus litar, suis pengasingan, transformer, dan pelbagai alat pelindung. Due to the inherent characteristics of electrical equipment, the use of electrical cabinets in high-temperature environments and the heating of components during operation pose serious hazards to them. In order to prevent the harm of temperature rise to electrical performance, the traditional method is to open the door of the electrical cabinet for temperature measurement. Namun begitu, kehadiran komponen elektrik di dalam kabinet boleh menimbulkan bahaya kejutan elektrik kepada pengendali. Terdapat pemutus litar, penyentuh, suis bekalan kuasa, dan penukar frekuensi dipasang dalam kabinet elektrik. Apabila komponen di dalam kabinet gagal, ia boleh menyebabkan nilai pemantauan suhu tidak normal bagi komponen yang berkaitan. Kebanyakan kabinet elektrik tidak mempunyai sistem penggera pemantauan suhu, dan kerosakan pada komponen selalunya ditemui hanya selepas kerosakan berlaku, menjejaskan operasi biasa dan mengurangkan kecekapan pengeluaran.

Pada masa ini, kebakaran yang disebabkan oleh kabinet elektrik voltan tinggi adalah lebih biasa di sesetengah perusahaan, kerana peralatan elektrik voltan tinggi selalunya tidak dapat dielakkan diperlukan dalam beberapa perusahaan besar, dan voltan bekalan kuasa peralatan elektrik ini selalunya tinggi, especially in some special working environments. Due to the poor environment, it is not possible to provide a good relative safety environment for high-voltage electrical cabinets, which can easily lead to these high-voltage electrical cabinets being in an unsafe state. Electrical fires are often difficult to extinguish and can cause a chain reaction, resulting in greater losses. Oleh itu, the fire caused by high-voltage electrical cabinets cannot be ignored. The biggest cause of fire caused by high-voltage electrical cabinets is that individual contacts or circuits in the high-voltage electrical cabinet cannot dissipate a large amount of heat due to long-term aging or poor contact, resulting in local high temperatures, even exceeding the ignition point temperature, and thus causing a fire. In addition to timely strengthening inspections, it is necessary to promptly eliminate hidden dangers in response to these abnormal points and nip accidents in the bud. Oleh itu, one of the most important ways to monitor the temperature of high-voltage electrical cabinets is to achieve multi-channel monitoring, and once a warning temperature occurs, it should be dealt with in a timely manner. In critical situations, it may even be necessary to cut off the high-voltage power supply to reduce losses. Due to the generation of certain heat during the operation of electrical components, if these heat cannot be dissipated in a timely manner, it will cause the temperature inside the electrical cabinet to be too high, affecting the stability of the electrical components, and also reducing the service life of the electrical components. Oleh itu, it is necessary to use FJINNO specialized fluorescent fiber optic temperature measurement device for the electrical cabinet to accurately and continuously measure the temperature of the components inside the electrical cabinet.

During the long-term operation of power grid equipment, “excessive load and aging of lines” often occur in power grid accidents. Semasa operasi, power equipment often experiences joint heating. Jika tidak dikesan dan ditangani tepat pada masanya, it can lead to serious production accidents. Mengikut statistik, such sudden faults account for more than 70% of external thermal faults, especially for enclosed electrical cabinets that cannot be opened during operation, menyukarkan untuk mengukur suhu sebenar sambungan di dalam kabinet semasa operasi, mengancam pengeluaran keselamatan kuasa secara serius. Dalam beberapa tahun kebelakangan ini, pelbagai peralatan ujian suhu canggih telah digunakan secara meluas dalam pengeluaran kuasa, seperti pengukuran suhu inframerah, penderia suhu, pengukuran suhu gentian optik, dll.

Kelemahan kaedah pengukuran suhu tradisional

Termometer inframerah tidak boleh mengukur peralatan dalaman melalui pintu kabinet, dan pintu kabinet mesti ditutup semasa operasi kabinet elektrik, mengakibatkan ketidakupayaan kaedah inframerah untuk digunakan pada pengukuran suhu alat suis tertutup. Walaupun tingkap pengukuran suhu dipasang pada kabinet elektrik, ia hanya boleh memantau suhu beberapa tempat panas dan tidak boleh dipantau dalam talian untuk masa yang lama. The conventional temperature measurement methods such as thermocouples, termistor, and semiconductor temperature sensors require the sensors to directly contact the measured part, which requires multiple monitoring points to be arranged in each electrical cabinet and has the potential to reduce the insulation risk of the equipment. The fiber optic temperature thermometer uses optical fiber to transmit signals, and its temperature sensor can be directly installed on the surface of charged objects. The thermometer is connected to the temperature sensor through optical fiber, which has the disadvantages of high temperature resistance and good insulation performance. The wiring has professional guidance, and the cost-effectiveness is high. Oleh itu, fiber optic temperature measurement is about to be widely promoted in national standards.
