这 fiber optic temperature online monitoring system for box type substation transformers can directly monitor the temperature of the low-voltage side circuit breaker contacts, 电缆接头, 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.

这 fluorescence fiber optic temperature online monitoring system consists of fluorescence fiber optic temperature sensors, 光纤温度传感器 (显示模块), 光缆, 等. Each box type transformer has no less than 6 温度测量点, including the low-voltage side circuit breaker contact temperature (3 points) and cable joint temperature (3 points). The final measurement points will be determined by the project unit. Real time online monitoring and fault alarm can be achieved. 除了在现场显示报警信息外, 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) 温度测量范围: -20~+150 ℃;
(2) 温度测量精度: ± 1 °C;
(3) Contact measurement method does not affect the insulation performance of the box transformer; The fluorescent fiber optic 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) 能够保存温度数据和报警温度时间等参数;
(6) 探头的使用寿命不得小于 30 年.
