Fiber optic online temperature measurement system for temperature monitoring of power reactor transformer ring main cabinet

Fluorescent fiber optic temperature measurement systems can be well applied in various fields, with the most commonly used being in power equipment.

1. Fluorescent fiber optic temperature measurement of reactors

Reactors are the main auxiliary equipment of long-distance transmission systems, playing an important role in power transmission due to their superior electrical performance. During the operation of a reactor, it is often due to external factors, internal structure, and other factors that the reactor may experience local temperature rise and overheating, ultimately leading to local burnout or even scrapping. This brings significant economic losses to the country and enterprises. Therefore, adopting a reactor fiber optic temperature measurement system and real-time monitoring of the internal temperature of the reactor is of great significance and practical value.

The reactor fiber optic temperature measurement adopts a fluorescent fiber optic temperature measurement device. The sensing probe of this device is made of imported quartz fiber, which has complete electrical insulation and is not affected by high voltage and strong electromagnetic fields. It is resistant to chemical corrosion and pollution, and has fast response speed, simple installation, and high temperature resistance. The backend software is used for real-time online monitoring.

2. Fluorescent fiber optic temperature measurement for dry-type transformers

The fluorescent fiber optic temperature measurement system for dry-type transformers aims to achieve isolation and shielding from external electrical interference signals in the operating environment of dry-type transformers, including power supply, signal input, signal output, and temperature control box casing. No metallic substances, intrinsic safety. In response to vibration, dust, moisture, oil and other on-site working environments, multi-layer protective measures are taken to ensure that the fiber optic temperature controller has good electromagnetic compatibility, ensuring stable and reliable operation.

3. Fluorescent fiber optic temperature measurement of ring main cabinet cable joints

The fiber optic temperature measurement system for the cable joint of the ring main unit adopts a fluorescent fiber optic temperature measurement device. The sensing probe of this device is made of imported quartz fiber optic material, which has complete electrical insulation and is not affected by high voltage and strong electromagnetic fields. It is resistant to chemical corrosion and pollution. Moreover, the temperature measurement probe has been processed by our company to increase the temperature measurement area, which can measure the temperature of the outer wall of the cable joint. The response speed is fast, the installation is simple, and it is resistant to high temperatures. At the same time, the system also provides remote web transmission, making it convenient for customers to install communication software and remotely monitor on any computer.
