Контроль оптоволоконного датчика температуры на трансформаторе в подстанции коробчатого типа

Волоконно-оптический датчик температуры, Интеллектуальная система мониторинга, Производитель распределенного оптоволокна в Китае

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

Тем fluorescence fiber optic temperature online monitoring system consists of fluorescence fiber optic temperature sensors, Волоконно-оптические датчики температуры (Дисплейные модули), Оптические кабели, и так далее. Each box type transformer has no less than 6 Точки измерения температуры, 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. В дополнение к отображению аварийной информации на объекте, 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) Диапазон измерения температуры: -20~+150 ℃;
(2) Точность измерения температуры: ± 1 °С;
(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) Возможность сохранения данных о температуре и аварийной сигнализации, температуры, времени и других параметров;
(6) Срок службы зонда должен быть не менее 30 годы.
