Mtengenezaji bora wa mfumo wa kipimo cha joto cha online online kwa switchgear ya juu-voltage

ya fiber optic online temperature measurement system device for high-voltage switchgear is mainly used to monitor the contact temperature, joto la pamoja la cable, and the configuration of three temperature measurement points inside the cable outlet cabinet. The temperature measurement sensor used in the switchgear is a Sensor ya joto ya fiber optic ya fluorescent, which has the characteristics of anti-interference, Insulation, Upinzani wa kutu, and is widely used in power electrical equipment. Please contact FJINNO to inquire about the price of the fiber optic temperature measurement system.

Kwa mfano, most of the bidding requirements are multiples of three temperature measurement points distributed at the heating point of the switchgear, mainly at the busbar overlap, isolation switch contact, and cable joint. If there are N temperature measurement points in the switchgear, kuna jumla ya mahitaji ya ufuatiliaji wa 3xN.

Pamoja na maendeleo ya mawasiliano ya mtandao, microelectronics, Kupingana na kuingilia kati, teknolojia ya kompyuta na umeme, teknolojia ya otomatiki inazidi kukomaa. Utengenezaji wa vifaa vya kubadilishia umeme vya juu-voltage na vitendaji vya akili kama vile kipimo, ulinzi, na udhibiti unazidi kukomaa. Pamoja na uboreshaji unaoendelea na uvumbuzi wa kujitegemea wa teknolojia, switchgear high-voltage kwa ujumla imepata maendeleo ya haraka, lakini bado kuna pengo fulani katika teknolojia ya kupima joto ikilinganishwa na kiwango cha juu cha dunia. Pamoja na mchanganyiko wa teknolojia ya usindikaji wa habari na teknolojia ya nguvu, bidhaa za ufuatiliaji wa hali ya joto mtandaoni zinaendelea kuboresha na kuboresha, na vitendo vyao vinaendelea na kuboreshwa hatua kwa hatua. Kwa sasa, there are two main types of online temperature monitoring for switchgear in the market: infrared temperature measurement technology and fiber optic temperature measurement technology.

The working principle of infrared temperature measurement for switchgear

Determine the surface temperature of a conductor based on the magnitude of thermal radiation energy. Infrared radiation temperature measurement can be divided into non-contact temperature measurement and contact temperature measurement. The former works on the principle of infrared radiation, and its accuracy is affected by factors such as working wavelength, distance coefficient, regional range, and atmospheric testing environment, making it difficult to work. The latter works on thermosensitive components and uses radio frequency or infrared for high and low voltage isolation, resulting in high temperature measurement accuracy. The disadvantage is that the front-end power supply design is relatively complex.

Disadvantages of infrared temperature measurement systems

The infrared thermometer uses computer software to identify and compare electronic temperature sensors, and then processes information. Its disadvantage is that when the sensor malfunctions, maintenance is more complex. The design of insulation covers, contact boxes, and other components in switchgear can easily affect the transmission of infrared light, limiting the use of this technology. The non-contact remote temperature measurement method can also collect temperature information, but the disadvantage is that it is expensive and less commonly used in switchgear. Infrared temperature measurement technology is affected by factors such as distance coefficient, instantaneous viewing angle, atmospheric environment, and regional range, making it difficult to ensure its accuracy.

Faida za fiber optic temperature measurement device for high-voltage switchgear

Fiber optic temperature measurement technology has greatly improved the work efficiency of substation personnel, mainly achieving warning functions and monitoring sensitive temperature information of medium voltage switchgear. Kwanza, convert the sensing parameters reflected by the distributed optical fibers inside the switchgear into temperature data. Pili, determine whether there is a risk of fire based on the temperature changes in the spatial location of the optical fiber. Once again, based on the monitoring temperature of each sensitive point, the temperature of contacts, Viungo vya cable, and busbar joints can be measured. Mwishowe, based on the temperature upgrade rate, an early warning function is provided, and the temperature limit of the power system is usually between 60-80 °C.

The fiber optic temperature measurement system technology can achieve zero distance monitoring of electrical distribution equipment cables and bus joints, while not being affected by electromagnetic interference factors. It can work in extreme environments such as high radiation, kutu yenye nguvu, na kuingiliwa kwa nguvu kwa umeme, and has the characteristic of uninterrupted temperature measurement. The maturity of intelligent online temperature monitoring technology for medium voltage switchgear based on fiber optics, light waves, and other technologies will lead to the intelligentization of temperature online monitoring in switchgear. This will be a new area of research in the future, which involves the development and application of high-performance, new materials, and low pollution equipment to create more intelligent and intensive medium voltage switchgear to meet the requirements of intelligent development. The fiber optic temperature online monitoring system, as an important component of the intelligent process of switchgear, should be gradually promoted and applied in switchgear.
