サーキットブレーカーに適した温度測定システムは何ですか?

サーキットブレーカーが使用される理由 温度監視システム

電力ケーブル業界の発展は非常に速いです, そして多くの配電ステーション制御システムが産業オートメーションを開始しています, 監視・監視システム通信デジタル化, 電源装置の保守と使用をより安全にします; 開閉装置のサーキットブレーカーは通常、運転中に使用されます。, これにより、サーキットブレーカーの動的接点と静的接点が摩耗しやすくなります。, 端子バスバーの留め具が緩んでいる, and other phenomena; サーキットブレーカーが温度監視の対象になっていない場合, 高温の熱を発生させる可能性がある, 開閉装置の絶縁コンポーネントの劣化を引き起こし、火災や電力機器の損傷につながる可能性があります。.

FJINNO’s fluorescent fiber optic temperature measurement system for switchgear circuit breakers effectively monitors and controls the temperature of the circuit breakers, making it convenient for on-site personnel to maintain the distribution cabinet. Reducing user losses and improving product maintenance and service life have achieved good economic benefits.

Temperature monitoring instrument for switchgear circuit breakers

The temperature operation monitoring of high-voltage switchgear is an important way to ensure the safe operation of the power system. しかし, traditional circuit breaker monitors only monitor the electrical parameters (電圧, 現在, そして力) in real time. しかし, due to the limitations of high voltage, measurement point positions, and strong electric field interference, the contact temperature is not monitored in real time online by general monitoring equipment.

蛍光光ファイバー温度監視 instrument for circuit breakers

最近では, switch cabinets are all small car type, because the circuit breaker and switch cabinet are connected by plugs. Poor manufacturing, 交通機関, and installation of the small car and switch cabinet can cause poor contact and increased contact resistance, resulting in high contact temperature rise or even burning, and power outage. These temperature rise phenomena are particularly prominent in high current switch cabinets such as incoming cabinets, which have a significant impact on the circuit breaker. The connection between the high-voltage switch contact and busbar is always in high voltage, 高温, high magnetic field, and extremely strong electromagnetic interference environments. Traditional temperature measuring instruments such as thermocouples and infrared thermometers are easily affected by these factors, making it difficult to accurately measure these positions and thus unable to truly obtain the high voltage switch cabinet. The actual temperature value, resulting in local overheating inside the equipment but still operating at high load, の 光ファイバー温度測定 device for monitoring the temperature of the contact arm of the circuit breaker can monitor the temperature of the contact arm of the circuit breaker online and detect thermal faults in the circuit breaker contact arm as soon as possible.

The temperature measurement methods for circuit breakers include infrared temperature measurement, 熱抵抗温度測定, および光ファイバー温度測定. Infrared temperature measurement is a direct measurement of an object’s surface by manually holding an infrared gun, which is easily affected by environmental temperature. Its biggest disadvantage is that it must be operated manually and cannot achieve online monitoring. Thermal resistors and thermocouples both require metal wires to transmit signals, which cannot solve insulation problems.

The fiber optic temperature detector for circuit breakers can monitor the temperature measurement of high voltage and high current electrical appliances. 例えば, for the temperature detection of the contact of 6-35kV vacuum circuit breakers, fluorescence fiber optic thermometers are mostly used. The fluorescence fiber optic thermometers consist of transmission fibers, 光ファイバー温度センサー, 光ファイバー温度トランスミッター, LCD display screens, およびその他のコンポーネント.
