Why do we need temperature measurement for aging cabinets
Со развојот на AC/DC пренос кон висок напон и голем капацитет, Компаниите за електрична енергија поставија повисоки барања за тековната носивост на високонапонската електрична опрема. Корисниците се надеваат дека ќе користат производи кои се стабилни, сигурен, и имаат подобри сеопфатни перформанси. Електричната опрема има строги барања за работна температура, а имаше и голем број случаи на прегревање на опремата поради кратки споеви и други причини, што резултира со сериозни загуби во трафостаниците. Следење во реално време на работната температура на електричната опрема, особено основната електрична опрема, е особено важно за да се избегнат загубите предизвикани од прегревање на електричната опрема.
The reason for the temperature rise in the aging cabinet
When conducting aging tests on electronic product aging cabinets, due to the large number of electronic products installed inside the cabinet, and the fact that the electronic products themselves dissipate heat, the temperature controllability inside the cabinet is poor. It is necessary to monitor the temperature inside the cabinet in real time to avoid high temperatures that can easily cause the failure of the tested product and result in losses. The existing temperature measurement technology for aging cabinets uses traditional thermocouples for temperature measurement, which has low monitoring efficiency and poor accuracy. The high and low temperature aging test of electronic products is a necessary means to eliminate early failures and control product quality. The uniformity of temperature distribution inside the aging cabinet is an important technical indicator of the aging cabinet, which will directly affect the aging results of electronic products placed in different aging cabinet areas.

Fiber optic sensing technology for aging cabinets
With the continuous development of sensing technology, people’s demand for sensor technology is also increasing day by day. Fiber optic sensors that meet the conditions of high sensitivity, ниска цена, simple preparation process, and good stability are rare. In the process of sensing and detection, sensitivity and stability are the main technical influencing factors, while the preparation process and cost are important influencing factors in industrial production. Во исто време, fiber optic sensors that combine these advantages are receiving increasing attention and favor.
Aging cabinet fluorescent fiber optic temperature measurement system
The aging cabinet fiber optic temperature measurement system can use fluorescent fiber optic temperature sensors. The cost of fluorescent fiber optic sensors is controllable, and single point multi-point temperature monitoring can comprehensively detect the situation of each point of the monitored object, with a large detection range; Secondly, the fiber optic probe is integrated with the signal channel and transmits optical signals. It is resistant to radio frequency and electromagnetic interference, flame and explosion, corrosion, high voltage and strong electromagnetic fields, and radiation, and can work in various harsh environments.
The fiber optic temperature measurement system of the new aging cabinet can accurately measure the temperature of various hotspots inside the aging cabinet by installing 3-point or 6-point температурни сензори со оптички влакна inside the cabinet. Fiber optic temperature sensors are arranged inside the cabinet to collect real-time temperature information inside the cabinet; The fluorescent fiber optic temperature sensor ultimately transmits temperature information to the fiber optic temperature measurement transmitter for analysis and calculation, and is ultimately centrally controlled by the controller; After real-time monitoring of temperature information, the controller can adopt control methods such as real-time display and alarm to avoid product failures caused by temperature changes inside the cabinet.
