The role of fiber optic temperature online monitoring system in box type substation
The fluorescence fiber optic temperature measurement system can directly monitor the temperature of the low-voltage side circuit breaker contacts, cable joints, and other parts of the box type substation. By using a fluorescence fiber optic temperature measurement probe, the temperature of the low-voltage side circuit breaker contacts and cable joints in the box type substation can be sensed. It can intuitively monitor and evaluate the operation of the box type substation, detect overheating problems at the contacts or joints in advance, and avoid adverse effects on the insulation and service life of the box type substation.
The fiber optic temperature online monitoring system for box type substations consists of fluorescent fiber optic temperature sensors, Glasvezel temperatuursensoren (display modules), optical cables, enz. Each box type substation has no less than 6 Temperatuur meetpunten, including 3 points for the low-voltage side circuit breaker contact temperature and 3 points for the cable joint temperature. It can monitor and fault alarm in real time online. In addition to displaying alarm information on site, it can also be transmitted to the monitoring background through RS485 port and achieve remote monitoring. The fiber optic temperature measurement system device must pass the type test integrated with the box type substation and provide relevant inspection reports.
The main technical parameters of the fiber optic temperature online monitoring system for box type substations are as follows:
(1) Meetbereik temperatuur: -20-+150 °C;
(2) Nauwkeurigheid temperatuurmeting: ± 1 °C;
(3) Contact measurement method, but shall not affect the insulation performance of the box type substation;
(4) The system is not affected by the electromagnetic environment inside the box type 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 jaren.
The principle of fluorescent Glasvezel temperatuursensor
Een fluorescerende glasvezel temperatuursensor is composed of a multimode fiber optic and a fluorescent object (membraan) geïnstalleerd aan de bovenkant. Fluorescerende stoffen zenden fluorescentie-energie uit wanneer ze worden gestimuleerd door licht van een bepaalde golflengte (gestimuleerd spectrum). Nadat de incentive is ingetrokken, De persistentie van fluorescentie-nagloeien is afhankelijk van factoren zoals de kenmerken van de fluorescerende stof en de omgevingstemperatuur. Deze aangeslagen fluorescentie vervalt meestal exponentieel, En de vervaltijdconstante wordt fluorescentielevensduur of fluorescentienagloeitijd genoemd. De verzwakking van de fluorescentie-nagloeiing varieert bij verschillende omgevingstemperaturen. Daarom, door de levensduur van fluorescentie-nagloeien te meten, De omgevingstemperatuur op dat moment kan worden bepaald.
