Fiber optic thermometers are used in which power grid applications

There are many kinds of fiber optic temperature measurement, such as fluorescent fiber optic temperature measurement, gallium arsenide fiber optic temperature measurement, distributed fiber optic temperature measurement, fiber grating temperature measurement and so on.

Fluorescent fiber optic temperature measurement can be mainly used in the power industry such as dry-type transformer temperature measurement, oil-immersed transformer winding temperature measurement. Switchgear fiber optic temperature measurement, ring cabinet fiber optic temperature measurement.

1, dry-type transformer fluorescent fiber temperature measurement

Dry-type transformer transformer fluorescent fiber optic temperature measurement device through continuous real-time collection of transformer winding temperature data, automatic storage of the highest temperature data, and real-time display of the highest temperature data, recording, storage and alarm output, to remind the staff to pay attention to, so that early warning. As the transformer temperature measurement device can be on the transformer temperature temperature monitoring, thus more conducive to the staff to determine the heating high temperature area in a timely manner, to determine the response program, take timely and accurate measures to prevent fire.

2, oil-immersed transformer winding temperature measurement

Fluorescent fiber optic temperature measurement technology used in oil-immersed transformer online temperature monitoring, real-time, accurate monitoring of the temperature of the components in the transformer, because it is a direct contact measurement, more than the theoretical calculations have more reference significance. In addition, through a long time of operation, it is proved that the monitoring system is safe, reliable and stable, and it can replace the winding thermometer and oil thermometer, and can replace the manual inspection. At the same time, through the detection of temperature, the life loss of the transformer can be assessed, and it is a good reference for the health status and life assessment of the transformer, which provides an effective technical means for online temperature detection of the transformer.

3、Switchgear fluorescent fiber optic temperature measurement

Switchgear Inno fiber optic temperature measurement system to solve the existing high-voltage switchgear manual monitoring, labor-intensive, inaccurate monitoring and can not be continuous time multi-point monitoring of the problem, to provide a low-voltage switchgear carrying an intelligent temperature measurement and monitoring system. Existing high-voltage cabinets are not set up with automatic monitoring system, and high-voltage cabinets in the process of long-term operation, power cable aging, switch contacts due to aging or contact resistance is too large, long-term high-current, high load operation of cables and switches and heat, easy to trigger contact erosion or high temperature deformation of the insulating barrier, carbonization, prone to cause accidents.

4, ring network cabinet fluorescent fiber optic temperature measurement

Numerous high-voltage electrical equipment itself, as well as high-voltage electrical equipment between the electrical contacts is the weakest link in power transmission, the essence of the problem is that the electrical contacts are hot. With the prolongation of the temperature rise time, the temperature exceeds the limit will increase the degree of oxidation due to heat, which may result in burned bus and contacts, contacts destroyed disk, power outages and other major accidents. Especially due to the switchgear cabinet with exposed high voltage, space is closed and narrow, can not be manually inspected to measure the temperature, so the use of fluorescent fiber optic temperature sensing technology real-time monitoring of high-voltage electrical contacts of the temperature rise is particularly important.
