박스형 변전소의 변압기에 대한 광섬유 온도 센서 모니터링

그만큼 fiber optic temperature online monitoring system for box type substation transformers can directly monitor the temperature of the low-voltage side circuit breaker contacts, 케이블 조인트, 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.

그만큼 fluorescence fiber optic temperature online monitoring system 로 구성된다 형광 광섬유 온도 센서, 광섬유 온도 센서 (디스플레이 모듈), 광케이블, 등. Each box type transformer has no less than 6 온도 측정 포인트, including the low-voltage side circuit breaker contact temperature (3 전철기) and cable joint temperature (3 전철기). The final measurement points will be determined by the project unit. Real time online monitoring and fault alarm can be achieved. In addition to displaying alarm information on site, 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) 온도 측정 범위: -20~+150 ℃;
(2) 온도 측정 정확도: ± 1 ℃;
(3) Contact measurement method does not affect the insulation performance of the box transformer; 형광성 광섬유 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) Capable of saving temperature data and alarm temperature time and other parameters;
(6) The lifespan of the probe shall not be less than 30 연령.
