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. No entanto, 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, o monitoramento real da temperatura não pode ser alcançado. Seja do ponto de vista da operação segura de equipamentos elétricos, como cabos e unidades principais em anel, ou do ponto de vista das necessidades de programação do sistema de energia, é necessário monitoramento em tempo real da capacidade de carga de cabos e equipamentos elétricos, o que pode ser alcançado através do monitoramento on-line em tempo real da temperatura no ponto de medição.

Com o desenvolvimento da transmissão AC/DC em direção a alta tensão e grande capacidade, as empresas de redes elétricas apresentaram requisitos mais elevados para a capacidade de transporte de corrente de equipamentos elétricos de alta tensão. Os usuários esperam usar produtos estáveis, confiável, e ter melhor desempenho abrangente. O equipamento elétrico tem requisitos rigorosos para temperatura operacional, 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, estabilidade e confiabilidade. There is no conductive part that causes additional temperature rise. Portanto, 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, medicina e outras áreas. 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.

Sensor de temperatura de fibra óptica 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, interferência anti-eletromagnética, 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, e empresas colaborando para desenvolver vários sistemas de medição de temperatura de fibra óptica para aplicação no local.

Características de Termômetros de fibra óptica

1. A fibra óptica inerentemente não tem interferência eletromagnética e não tem medo de interferência eletromagnética;

2. É relativamente fácil de ser recebido por vários dispositivos de detecção de luz e pode realizar convenientemente conversão fotoelétrica ou eletro-óptica;

3. Fácil de combinar com dispositivos eletrônicos e computadores modernos altamente desenvolvidos;

4. Os cabos de fibra óptica têm uma ampla frequência operacional e uma grande faixa dinâmica, tornando-os uma linha de transmissão de baixa perda;

5. A fibra óptica em si não é carregada, pequeno em tamanho e leve em peso, fácil de dobrar, e tem boa resistência à radiação. É particularmente adequado para uso em ambientes agressivos, como ambientes inflamáveis, explosivo, espaço limitado, e forte interferência eletromagnética.

Characteristics and advantages of distributed fiber optic thermometer

The fiber optic sensor of the fibra óptica distribuída thermometer has the advantages of extremely high sensitivity and accuracy, inherent good safety, resistência à interferência eletromagnética, high insulation strength, resistência à corrosão, integration of sensing and transmission, and compatibility with digital communication systems.

(1) High sensitivity and fast response speed;

(2) Fiber optic cables are lightweight, flexível, 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) Interferência anti-eletromagnética. 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) Medição distribuída. A single optical fiber can achieve long-distance continuous measurement, accurately measuring information such as strain, dano, vibração, and temperature at any point, and thus forming a monitoring area with a large range, improving environmental monitoring technology;

(7) Longa vida útil. 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 termômetro de fibra óptica

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, e assim por diante. The quality of fiber optic temperature measurement equipment is also closely related to its price.
