Why do we need temperature measurement for aging cabinets

With the development of AC/DC transmission towards high voltage and large capacity, power grid companies have put forward higher requirements for the current carrying capacity of high-voltage electrical equipment. Users hope to use products that are stable, reliable, and have better comprehensive performance. Electrical equipment has strict requirements for operating temperature, and there have been a large number of cases of equipment overheating due to short circuits and other reasons, resulting in serious losses in substations. Real time monitoring of the operating temperature of electrical equipment, especially core electrical equipment, is particularly important to avoid losses caused by overheating of electrical equipment.

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.

Traditional temperature measurement technology for electronic aging cabinets

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 uses traditional thermocouples for inspection, which have low monitoring efficiency and poor accuracy.

Fiber optic sensing technology for aging cabinets

Զգայական տեխնոլոգիայի շարունակական զարգացմամբ, people’s demand for sensor technology is also increasing day by day. Fiber optic sensors that meet the conditions of high sensitivity, ցածր գնով, պատրաստման պարզ գործընթաց, and good stability are rare. Զգացման և հայտնաբերման գործընթացում, զգայունությունը և կայունությունը հիմնական տեխնիկական ազդեցիկ գործոններն են, while the preparation process and cost are important influencing factors in industrial production. Միևնույն ժամանակ, 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; Երկրորդ, 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 օպտիկամանրաթելային ջերմաստիճանի տվիչներ 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.
