The fiber optic temperature measurement system can be applied to high-voltage switchgear, dry-type transformers, oil immersed power transformers, and strong electromagnetic environments for temperature monitoring. It has stable performance and accurate temperature measurement, and is produced and sold by the top ten fluorescent fiber optic temperature measurement factories in China.

The necessity of online temperature monitoring system for high-voltage switchgear

High voltage switchgear is an important equipment in the power system. Its main function is to disconnect and close power lines, protect against line faults, and monitor operating power data. The advantages of high-voltage switchgear are safety and reliability, compact structure, small footprint, and easy operation. Switching stations, residential distribution rooms, and substations are the main application places for high-voltage switchgear.

High voltage switchgear temperature rise monitoring system

In high voltage, high current, and strong magnetic field environments, the temperature rise of high voltage switchgear is the main system concern of switchgear. During long-term operation, high voltage switchgear may experience loose contact springs, poor contact of high voltage switchgear contacts, and aging of important components. If maintenance measures are not taken in a timely manner, the temperature rise of high voltage switchgear contacts can easily cause equipment damage. Þess vegna, online monitoring of their temperature can prevent them from operating in a fault state and ensure the safe and reliable operation of the entire power system.

High voltage switchgear fluorescent fiber optic temperature measurement system

Traditional types of temperature sensors such as thermocouples, thermistors, semiconductor thermometers, o.s.frv. are all based on electrical signals. Temperature signals need to be converted into electrical signals and processed, which can no longer fully meet the needs of various temperature measurement environments. Þess vegna, FJINNO has independently developed a new type of fiber optic temperature sensor.

The advantages of the fluorescent fiber optic temperature measurement system for high-voltage switchgear include long host life and immunity to electromagnetic interference. The fiber optic temperature measurement system can provide effective protection for online temperature monitoring of high-voltage switchgear and other equipment in substations, timely transmitting the online temperature of the equipment to the background, extending the service life of the switchgear, and providing strong backup guarantee for the safe operation of high-voltage equipment.

Installation method of fluorescent fiber optic temperature monitoring device

The sensor probe of the ljósleiðara hitaskynjari is connected to the main controller of the fiber optic access device. The fiber optic temperature sensor is installed at the switch contacts, busbar, and cable joints inside the switchgear to achieve online monitoring of the internal temperature of the switchgear.

The temperature online monitoring device for switchgear adopts advanced system installation methods and software backend monitoring of temperature, which enables real-time online monitoring of the temperature of various electrical connection points of power system switchgear, realizing the function of early detection and alarm of abnormal temperature rise of conductors. It changes the previous practice of manual inspection or only discovering and handling fault points after accidents occur, truly realizing temperature monitoring and status maintenance, ensuring the construction and safe operation of smart grids.
