开关设备温度传感器 使用光纤温度传感器

As one of the important equipment in the power system, high-voltage switchgear plays an important role in breaking and closing power lines, line fault protection, monitoring operating energy data, and is widely used in switch stations, residential distribution rooms, and substations due to its advantages of safety, 可靠性, compact structure, small footprint, 操作简单. High voltage switchgear generally operates in high voltage, 大电流, and strong magnetic field environments, and temperature rise is an important parameter. 然而, after long-term operation, high voltage switchgear often produces loose contact springs, poor contact, or aging of certain parts. If measures are not taken in time, the contact temperature will increase sharply, which is prone to equipment damage. 因此, online monitoring of its temperature can avoid its operation in a faulty state, ensuring the safe and reliable operation of the entire power system.

Traditional types of 温度传感器, 如热电偶, thermistors, semiconductor thermometers, 等。, rely on electrical signals as their working basis. Temperature signals need to be converted into electrical signals for further processing, which no longer fully meets the needs of scientific and industrial development.

这 荧光光纤温度测量 device applied to high-voltage switchgear has a long service life and is resistant to electromagnetic interference. It can provide effective protection for temperature monitoring of high-voltage switchgear and other equipment in substations, judge the equipment’s ability and service life, and provide scientific basis for safe operation of equipment.

By utilizing the advantages of small volume, strong resistance to electromagnetic interference, and good insulation of fluorescent fiber optic temperature sensors, temperature monitoring of isolation contacts in high-voltage switchgear has been achieved instead of electronic sensors. The fiber optic temperature measurement system scheme does not require complex insulation design, thus having the advantages of simplicity and reliability. 这 荧光光纤测温系统 solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. 这 光纤测温系统 has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
