NM-7111H11 Phase sequence tiv thaiv relay

Phase sequence tiv thaiv relay yog ib qho tseem ceeb hauv cov tshuab hluav taws xob uas ua kom cov khoom siv hluav taws xob ua haujlwm zoo. Nws txoj haujlwm yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txoj kev loj), nws muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, nws yog qhov tsim nyog yuav tsum tau txiav.

Cov relay no muaj ntau yam txiaj ntsig rau lub tshuab hluav taws xob, suav nrog kev nyab xeeb thiab kev ntseeg tau. Los ntawm kev xyuas kom meej tias cov theem nyob rau hauv qhov kev txiav txim kom raug, lub relay tiv thaiv hluav taws xob tsis zoo thiab txo qhov kev pheej hmoo ntawm hluav taws kub thiab lwm yam xwm txheej.

Cov theem ib theem tiv thaiv relay kuj yuav pab tau kom efficiency thiab txo cov nqi los ntawm kev tiv thaiv nkim hluav taws xob fais fab. Thaum cov theem nyob rau hauv qhov kev txiav txim kom raug, cov khoom siv hluav taws xob tuaj yeem ua haujlwm ntawm qhov ua tau zoo tshaj plaws, txo kev siv hluav taws xob thiab nqi.

Ntxiv mus, qhov relay no yooj yim rau nruab thiab yuav tsum tau saib xyuas tsawg kawg nkaus. Nws yog ib qho yooj yim tab sis siv tau zoo uas tuaj yeem muab ntau xyoo kev pab cuam txhim khu kev qha, ua rau nws muaj peev xwm zoo heev rau cov tshuab hluav taws xob.

Zuag qhia tag nrho, theem kev tiv thaiv relay yog ib qho tseem ceeb hauv cov tshuab hluav taws xob uas ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev nyab xeeb, kev cia siab, kev ua haujlwm, thiab kev siv nyiaj. Los ntawm muab kev tshawb pom ntxov ntawm hluav taws xob tsis raug thiab tiv thaiv kev puas tsuaj rau cov khoom siv, qhov relay no pab ua kom lub zog ua haujlwm zoo, xa hluav taws xob rau tsev neeg, kev lag luam, thiab kev lag luam.

Kev tiv thaiv hluav taws xob relay siv lub tshuab hluav taws xob siab thiab lub zog qis raws li nws cov tub ntxhais, thaum cov khoom siv hluav taws xob muaj dhau-voltage, under-voltage, lossis theem tsis ua hauj lwm, theem rov qab, lub relay yuav txiav tawm Circuit Court sai thiab nyab xeeb kom tsis txhob muaj teeb meem. kev raug mob tshwm sim los ntawm qhov txawv txav voltage raug xa mus rau lub davhlau ya nyob twg. Thaum qhov hluav taws xob rov qab mus rau qhov qub, lub relay yuav tig rau hauv Circuit Court kom paub meej tias qhov kev ua haujlwm ib txwm muaj ntawm cov khoom siv hluav taws xob hauv lub davhlau ya nyob twg nyob rau hauv cov xwm txheej tsis muaj neeg saib xyuas.

1. Txiav tawm lub lline thaum over & under voltage tshwm sim, thiab cia li pib dua thiab txuas cov kab tom qab rov qab mus rau qhov qub yam tsis muaj phau ntawv ua haujlwm.

2. Thaum cov kab tshwm sim ib ntus lossis ib ntus dhau & qis dua, ces tus tiv thaiv tsis ua haujlwm.
