Paano sukatin ang temperatura ng oil immersed transformer windings

The direct measurement method is to embed a fluorescent fiber optic temperatura sensor in the winding, and use the fiber optic propagation signal to achieve online and real-time measurement of the hot spot temperature of the winding under high voltage and high magnetic field conditions. The fiber optic thermostat is determined by measuring the inherent parameters (attenuation time) of the phosphor alone, and will not change due to physical changes in the fiber optic. It is a system that does not require verification. The temperature sensor is made of a stable high-temperature resistant fluorescent material and directly attached to the end of the fiber optic probe. The probe is compatible with oil immersed transformers for a long time and has excellent electrical performance.

Ang data ng pagsukat ng fiber optic probe ay ipinapadala sa controller ng temperatura sa pamamagitan ng isang independiyenteng output at display na channel sa pagsukat. Ang gumaganang prinsipyo ng direktang pagsukat ay kapag ang liwanag na pulso na ibinubuga ng pinagmumulan ng liwanag ay ipinadala sa temperatura sensor sa contact na may paikot-ikot sa pamamagitan ng optical fiber, the pulse excites the fluorescent material of the sensor, causing it to produce longer wavelength fluorescence. Measure the temperature of the sensor based on the decay time of the returned fluorescence, and then process it to display the temperature value and relevant system parameters. Kasabay nito, transmit the temperature information to the control room.
