Fiber optic temperature online monitoring system for power switchgear manufacturers-INNO

インテリジェント電力網の発展に伴い, 物流システムのデジタル化・ネットワーク化を提案しながら, 配電システムにおける高電圧開閉装置の動作の信頼性と自動化レベルに対して、より高い要件が提示されています。. 高圧開閉装置の現場運転中, さまざまな要因が過熱を引き起こしやすい, 機器の絶縁劣化の加速, そして重症の場合, 機器の安全な動作を危険にさらす. パワーユーザーがこれを適切に防止および制御しない場合, 暖房障害が拡大し、直接的および間接的に重大な経済的損失を引き起こす可能性がある.

電力システムの主な電気機器は、通常、サーキットブレーカーなどの電気機器で構成されます。, トランスフォーマー, ケーブル, バスバー, および開閉装置; それらはバスバーによって互いに接続されています, リード, ケーブル, 等. 接続点に電流が流れるため、, 熱は必然的に発生します, ほとんどすべての電気的故障は、故障点で温度変化を引き起こします。; そこで, 開閉装置などの電力システムの機器の温度監視は、障害をタイムリーに検出するための一般的な方法です。. 長年にわたって, 技術的な限界のため, the safe operation level of the power system has been somewhat restricted. 赤外線温度計ですが、, 赤外線撮像装置, 温度感知ケーブル, and traditional point based temperature measurement systems have been used to solve the above problems, real-time monitoring cannot be achieved and only regular inspections can be carried out, which poses a safety hazard of missed detection and reporting. さらに, in recent years, ワイヤレス温度測定 has gradually been adopted to measure device contacts, which to some extent solves the blindness caused by regular monitoring in the past. しかし, due to the need for such sensors, it is urgent to develop a set of temperature monitoring equipment suitable for high-voltage switchgear and knife switches.

Price of fiber optic sensing for switchgear

The price of 蛍光光ファイバー温度センサー for switchgear is related to many factors, such as the number of temperature measurement points and the length of the fiber optic cable. The temperature measurement system for enclosed switchgear in substations is an online monitoring and warning system designed for early prediction of high temperatures caused by insulation aging or poor contact in high-voltage switchgear, high-voltage porcelain bottles, and high-voltage cable cores in substations. By monitoring the temperature at multiple points, possible faults can be predicted to prevent accidents from occurring. The temperature measurement system of the enclosed switchgear in the substation adopts advanced communication technology, マイクロプロセッサ技術, and digital temperature sensing technology. Innovative design for low-temperature, 強電界, ・湿度環境運転技術. The main material of this system is optical fiber, which avoids strong electromagnetic interference inside the transformer winding and safely transmits data to the monitoring terminal. Not only is it resistant to high temperature and high voltage, but it also has extremely high insulation strength, and prevents dust accumulation, avoiding the possibility of creepage. そこで, the system is a highly reliable fluorescent fiber online monitoring system. The temperature measurement system of the switchgear has a good computer interface, can display a simulated diagram of the high-voltage switchgear group, display the actual position monitored by the sensor and all intermediate head positions, as well as the parameters of the switchgear knife switch. When there are abnormalities in the cables and switchgear during operation, the display screen and accident sound simultaneously emit alarm signals, which can be directly viewed through the simulated diagram of the switchgear group on the computer, and can quickly and accurately determine the actual location of the fault, greatly improving the reliability and technical management level of switchgear operation. In order to better connect with other systems, the system adopts standard communication interfaces and protocols: RS232 and 485 仕様, supports IPX and TCP/IP protocols, and can be interconnected with the management network due to the use of the INTERNET standard.
