AA Sensor

Kev tso tawm ib nrab (PD) yog ib qho ntawm qhov ua txhaum uas tshwm sim vim qhov tsis xws ntawm tus neeg siv hluav taws xob siab -voltage rwb thaiv tsev system. Cov neeg siv yuav tsum ntsuas qhov tso tawm ib nrab los saib xyuas cov khoom siv thiab tsis txhob ua txhaum. Qhov no sensor yog ib qho kev tivthaiv rau huab cua ultrasonic ib feem paug paug nrhiav kom tau, thiab yuav siv tau ua ke nrog ultrasonic ib feem paug detector los ua ib tug tiav PD nrhiav kom tau qhov system rau siab - cov khoom voltage. Cov khoom siv sab hauv xws li insulators, tes tsho, busbars, thiab terminals tsim kev vibrations thaum lub sij hawm tso tawm, uas ces propagated los ntawm huab cua media. AA (Air Ultrasonic) sensors siv lub hauv paus ntsiab lus no kom nkag siab qee qhov tso tawm cov cim, thiab nws tseem yog ib feem tseem ceeb ntawm kev tso tawm ultrasonic ntsuas ib nrab rau siab - rhiab heev ntawm huab cua- ua rau PD vibration signals. Thaum ua ke nrog uhf sensor ib feem ntawm cov khoom siv tawm, nws tuaj yeem paub ntau yam - qhov sib txawv fusion nrhiav pom ntawm ib feem ntawm cov pa tawm, npog ob qho tib si ultrasonic thiab ultra-siab zaus teeb liab tau, thiab zoo heev txhim kho qhov kev nkag siab thiab raug ntawm PD txhaum kev kuaj mob rau cov khoom siv hluav taws xob siab{11}
