Phase Failure Detector

PHASE FAILURE ntesCCX 1

General

Ib qho ntawm cov teeb meem uas tshwm sim hauv cov nroj tsuag kev lag luam yog overheating thiab kev puas tsuaj ntawm 3 theem motors vim yog theem tsis ua hauj lwm. Thermionic - cov khoom siv hlau nplaum uas yog ib qho tseem ceeb hauv kev tiv thaiv lub cev muaj zog feem ntau qeeb heev vim nws cov khoom siv hluav taws xob thiab kev siv ntau tshaj qhov teeb tsa tam sim no kom paub meej tias tsis muaj kev tawm mus. Raws li tsim los tshem tawm cov txiaj ntsig saum toj no, Manhua PHASE Failure detector Devices ua haujlwm rau kev tiv thaiv hauv qab no.

1. Phase Failure

Thaum cov kev soj ntsuam 3 theem voltages siv tau, qhov tso zis relay yog qhib: yog tias ib qho ntawm 3 Theem tsis ua haujlwm, cov khoom siv hluav taws xob hloov tau OFF tam sim ntawd, Relay LED yog OFF, Asymmetry thiab Phase Sequence yuam kev LEDs yog ON.

2. Theem Sequence

Thaum cov theem ua ntu zus yog lawm (L1, L2, L3 nyob rau hauv clockwise kev taw qhia) cov zis relay yog qhib: txawm li cas los xij, yog tias qhov sib lawv liag hloov los ntawm ib qho laj thawj, qhov tso tawm relay keyboards OFF tam sim.Relay LED yog OFF, Phase Sequence yuam kev LED yog ON.

3. Voltage Unbalance (ob qho tib si Unbalance thiab ncua ncua adjustable)

Thaum cov theem {{0}}theem voltage unbalance tsawg dua tus nqi kho los ntawm tus neeg siv, tso zis relay yog qhib.Yog hais tias tus nqi unbalance tshaj qhov txwv tus nqi (5 -15) teem los ntawm lub neeg siv, tawm tso relay yog switched OFF thaum kawg ntawm ncua sij hawm (0.1 10s) uas kuj teem los ntawm tus neeg siv. Relay LED yog OFF, Asymmetry yuam kev LED ON.Yog hais tias qhov txhaum ploj nyob rau hauv lub sij hawm ncua, Kab tso zis relay tsis hloov OFF. Qhov voltage unbalance tshwm sim yog cov theem L1, L2, L3 yog loaded unequally.Qhov no yog tshwm sim los ntawm anon-uniform tis ntawm loads ntawm cov kab.Qhov voltage asymmetry ua rau nce nyob rau hauv lub cev muaj zog kub thiab txo cov rated motor zog. Voltage asymmetry txwv qhov tseem ceeb yog hloov kho (5 -15) los ntawm tus neeg siv. Hysteresis yog tsau ntawm 20.

4. Cov khoom tsis txaus

L1 yog theem khoom ntawm MK-05 thiab MK-05P hauv PK21 pob thaum. Rau MK thiab MKC cov khoom siv yog tias cov khoom siv hluav taws xob poob qis dua 60-65 ntawm qhov ntsuas hluav taws xob, cov khoom siv hluav taws xob hloov tawm yam tsis muaj ncua sij hawm thiab qhov yuam kev LED pib ntsais ib qho tom qab ib ntus.

PRECAUTONS RAU INSTALLATON thiab siv kev nyab xeeb

Tsis ua raws li cov lus qhia no yuav ua rau tuag lossis raug mob hnyav. Tshem tawm txhua lub zog ua ntej ua haujlwm ntawm cov khoom siv.

Thaum lub cuab yeej txuas nrog lub network, tsis txhob tshem lub vaj huam sib luag pem hauv ntej.

Tsis txhob sim ntxuav lub cuab yeej nrog cov kuab tshuaj los yog cov zoo li.Tshuaj xyuas cov kev sib txuas ntawm lub davhlau ya nyob twg kom raug thaum xaim.

Cov khoom siv hluav taws xob yuav tsum tau muab kev pabcuam los ntawm koj tus neeg muag khoom codependent nkaus xwb.
