Why use a fiber optic thermometer

With the implementation of power grid renovation, especially the continuous deepening of urban network renovation and construction, the usage of cables and electrical equipment has increased significantly, which has made the operation management, monitoring and maintenance of cables and electrical equipment very important. In practical work, in order to avoid cables and electrical equipment from overheating at high temperatures, it is usually necessary to choose a method that appropriately preserves their load capacity. Duk da haka, this makes the use of these cables and electrical equipment uneconomical, and manual inspection can only detect the surface temperature of the test point. For enclosed electrical equipment such as cables and switchgear, true temperature monitoring cannot be achieved. Whether from the perspective of the safe operation of electrical equipment such as cables and ring main units or from the perspective of power system scheduling needs, real-time monitoring of the load capacity of cables and electrical equipment is required, which can be achieved through online real-time monitoring of the temperature at the measurement point.

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.

Fiber optic temperature measurement technology has the characteristics of anti electromagnetic interference, voltage insulation, kwanciyar hankali da aminci. There is no conductive part that causes additional temperature rise. Saboda haka, fiber optic temperature measurement technology has significant advantages in the field of temperature measurement and has received widespread attention in many industries, especially in transmission and transformation, medical and other fields. The chassis of the fiber optic thermometer is an important component, and its design is related to whether the instrument is convenient to use and whether the data is true and effective.

Fiber optic temperature sensor is a new type of temperature measurement technology developed in recent years, and it is also a major product in the fiber optic sensor family. It is based on optical signal transmission of information and has advantages such as insulation, anti electromagnetic tsangwama, and high voltage resistance. In foreign countries, fiber optic temperature sensors have developed rapidly, forming various models of products and have been applied in multiple fields, achieving good results. Domestic research in this area is also flourishing, with multiple universities, research institutes, and companies collaborating to develop various fiber optic temperature measurement systems for on-site application.

Characteristics of Fiber Optic Thermometers

1. Fiber optics inherently do not have electromagnetic interference and are not afraid of electromagnetic interference;

2. It is relatively easy to be received by various light detection devices and can conveniently perform photoelectric or electro-optical conversion;

3. Easy to match with highly developed modern electronic devices and computers;

4. Fiber optic cables have a wide operating frequency and a large dynamic range, making them a low loss transmission line;

5. Fiber optic itself is not charged, small in size and light in weight, easy to bend, and has good radiation resistance. It is particularly suitable for use in harsh environments such as flammable, explosive, space limited, and strong electromagnetic interference.

Characteristics and advantages of distributed fiber optic thermometer

The fiber optic sensor of the distributed fiber optic thermometer has the advantages of extremely high sensitivity and accuracy, inherent good safety, resistance to electromagnetic interference, high insulation strength, juriya na lalata, integration of sensing and transmission, and compatibility with digital communication systems.

(1) High sensitivity and fast response speed;

(2) Fiber optic cables are lightweight, flexible, and easy to install and bury;

(3) Good electrical insulation and chemical stability.

Fiber optic itself is a highly insulating and chemically stable substance, suitable for use in harsh environments such as high voltage isolation and flammable and explosive environments in power and chemical systems;

(4) Good security. Fiber optic sensors are electrically passive sensitive components, so they are used for temperature measurement without any safety hazards such as leakage or electric shock;

(5) Anti electromagnetic tsangwama. In general, the frequency of light waves is higher than that of electromagnetic radiation, so the propagation of light in optical fibers is not affected by electromagnetic factors;

(6) Distributed measurement. A single optical fiber can achieve long-distance continuous measurement, accurately measuring information such as strain, damage, vibration, and temperature at any point, and thus forming a monitoring area with a large range, improving environmental monitoring technology;

(7) Long service life. The main material of fiber optic sensors is stable, wrapped in a polymer material coating, which gives it greater durability compared to metal sensors;

(8) Large transmission capacity. Using optical fibers as busbars, large capacity optical fibers are used instead of cables to collect and store information from various sensing points, and distributed optical fiber sensor monitoring is achieved through multiplexing technology.

How much is the price of a fiber optic thermometer

Fiber optic thermometers have many advantages compared to other traditional thermometers, so their prices are also different. The price of fiber optic thermometers is related to many factors, such as the number of fiber optic temperature measurement channels, the length of the transmission fiber, and so on. The quality of fiber optic temperature measurement equipment is also closely related to its price.
