Ufuatiliaji wa sensor ya joto ya nyuzi kwenye transformer katika muundo wa aina ya sanduku

ya mfumo wa ufuatiliaji wa joto la nyuzinyuzi mtandaoni for box type substation transformers can directly monitor the temperature of the low-voltage side circuit breaker contacts, Viungo vya cable, 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.

ya fluorescence fiber optic temperature online monitoring system inajumuisha Fluorescence fiber optic joto sensorer, sensorer ya joto ya macho ya fiber (kuonyesha modules), nyaya za macho, Nk. Each box type transformer has no less than 6 Vipimo vya kipimo cha joto, including the low-voltage side circuit breaker contact temperature (3 vidokezo) and cable joint temperature (3 vidokezo). 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 mfumo wa ufuatiliaji wa joto la nyuzinyuzi mtandaoni are as follows:
(1) Upimaji wa joto: -20~+150 ℃;
(2) Usahihi wa kipimo cha joto: ± 1 °C;
(3) Contact measurement method does not affect the insulation performance of the box transformer; Nuru ya umeme Optic ya nyuzi 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 Miaka.
