ボックス型変電所の変圧器の光ファイバー温度センサー監視

ザ fiber optic temperature online monitoring system for box type substation transformers can directly monitor the temperature of the low-voltage side circuit breaker contacts, ケーブルジョイント, and other parts of the box transformer. By using fluorescent fiber optic temperature probes, the temperature of the low-voltage side circuit breaker contacts and cable joints of the box transformer can be sensed, and the operation of the box transformer can be intuitively monitored and evaluated. Overheating problems at the contacts or joints can be detected in advance to avoid adverse effects on the insulation and service life of the box transformer.

ザ fluorescence fiber optic temperature online monitoring system consists of fluorescence fiber optic temperature sensors, 光ファイバー温度センサー (ディスプレイモジュール), 光ケーブル, 等. Each box type transformer has no less than 6 温度測定ポイント, including the low-voltage side circuit breaker contact temperature (3 ポイント) and cable joint temperature (3 ポイント). The final measurement points will be determined by the project unit. Real time online monitoring and fault alarm can be achieved. 現場でのアラーム情報の表示に加えて, it can also be transmitted to the monitoring background through RS485 interface and achieve remote monitoring. The temperature monitoring system device has passed the type test integrated with the box transformer and provided relevant inspection reports.

The main technical parameters of the box transformer fiber optic temperature online monitoring system are as follows:
(1) 温度測定範囲: -20~+150 ℃;
(2) 温度測定精度: ± 1 °C°C;
(3) Contact measurement method does not affect the insulation performance of the box transformer; The fluorescent ファイバー sensor has passed the power frequency withstand voltage test, with a 20cm withstand voltage of no less than 80kV, and an inspection report provided;
(4) The system is not affected by the electromagnetic environment inside the substation and provides relevant electromagnetic compatibility test reports;
(5) 温度データ、アラーム、温度時間、その他のパラメータを保存できます;
(6) プローブの寿命は、以下を下回ってはなりません 30 月日.
