Why do we need temperature measurement for aging cabinets

Con lo sviluppo della trasmissione AC/DC verso l'alta tensione e la grande capacità, Le società di rete elettrica hanno avanzato requisiti più elevati per la capacità di trasporto di corrente delle apparecchiature elettriche ad alta tensione. Gli utenti sperano di utilizzare prodotti stabili, affidabile, e avere migliori prestazioni complete. Le apparecchiature elettriche hanno requisiti rigorosi per la temperatura di esercizio, E ci sono stati un gran numero di casi di surriscaldamento delle apparecchiature a causa di cortocircuiti e altri motivi, con conseguenti gravi perdite nelle sottostazioni. Monitoraggio in tempo reale della temperatura di esercizio delle apparecchiature elettriche, in particolare le apparecchiature elettriche di base, è particolarmente importante per evitare perdite causate dal surriscaldamento delle apparecchiature elettriche.

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.

The existing temperature measurement technology uses traditional thermocouples for inspection, which have low monitoring efficiency and poor accuracy.

Fiber optic sensing technology for aging cabinets

Con il continuo sviluppo della tecnologia di rilevamento, people’s demand for sensor technology is also increasing day by day. Fiber optic sensors that meet the conditions of high sensitivity, Basso, Processo di preparazione semplice, and good stability are rare. Nel processo di rilevamento e rilevamento, sensibilità e stabilità sono i principali fattori di influenza tecnica, while the preparation process and cost are important influencing factors in industrial production. Allo stesso tempo, 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; Secondariamente, 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, corrosione, high voltage and strong electromagnetic fields, e radiazioni, 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 Sensori di temperatura in fibra ottica 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.
