Kev tswj thiab pib cov twj tso kua mis submersible feem ntau muab faib ua plaub hom raws li lawv txoj haujlwm thiab cov kev xav tau: cov khoom pib ncaj qha, Y- zoo li lub hnub qub delta siab txo cov khoom pib, autotransformer siab txo qhov pib ntaus ntawv, thiab qhov sib txawv zaus siab txo qhov pib ntaus ntawv. Cov hauv qab no yuav qhia txog cov yam ntxwv ua haujlwm ntawm txhua qhov pib ntaus ntawv ib los ntawm ib qho.
1. Pib lub cuab yeej ncaj qha
Lub tshuab pib ncaj qha yog tsim rau qis- lub zog submersible motors thiab cov twj siv hluav taws xob submersible. Cov khoom pib muaj cov khoom siv xws li contactors thiab relays, uas tuaj yeem tiv thaiv lub submersible motors thiab submersible electric twj los ntawm kev ua haujlwm tsis zoo xws li overload, theem tsis ua haujlwm, xauv rotor, thiab undervoltage thaum lub sijhawm ua haujlwm. Nws tseem tuaj yeem nruab nrog kev tiv thaiv xws li stator winding overheating.
2. Lub hnub qub delta pib ntaus ntawv
Lub hnub qub lub kaum sab xis txo qhov pib ntaus ntawv kuj tseem tsim nyog rau siab - lub zog submersible motors thiab submersible twj. Cov khoom pib muaj ob txheej ntawm contactors thiab relays, uas tuaj yeem ua tau Y - △ voltage txo pib ntawm submersible motors thiab submersible twj; Nws tseem tuaj yeem tiv thaiv kev ua haujlwm txawv txav xws li overload, theem tsis ua haujlwm, xauv lub rotor, thiab undervoltage uas tshwm sim thaum lub sijhawm ua haujlwm ntawm submersible motors thiab submersible twj; Kev ua haujlwm ntawm lub twj tso kua mis submersible kuj tseem tuaj yeem tswj tau raws li kev hloov pauv hauv cov kua theem lossis siab; Thiab nws tuaj yeem nruab nrog kev tiv thaiv tshwj xeeb xws li stator winding overheating, bearing overheating, thiab dej nkag mus rau hauv lub cev muaj zog lossis roj chamber.
3. Self coupling voltage txo qhov pib ntaus ntawv
Lub autotransformer voltage txo qhov pib ntaus ntawv yog tsim nyog rau siab -lub zog submersible motors thiab submersible twj. Ntxiv rau cov khoom xws li contactors thiab relays, cov khoom pib yog nruab nrog autotransformer nyob rau hauv lub tswj vaj huam sib luag, uas tuaj yeem txo qhov voltage pib ntawm submersible motors thiab submersible twj; Nws tuaj yeem tiv thaiv kev ua haujlwm txawv txav xws li overload, theem tsis ua haujlwm, xauv lub rotor, thiab undervoltage generated thaum lub sij hawm ua hauj lwm ntawm submersible motors thiab submersible twj; Tsis siv neeg tswj kev ua haujlwm ntawm cov twj siv hluav taws xob submersible raws li kev hloov pauv hauv cov kua theem lossis siab; Qhov dej tuaj yeem nruab nrog kev tiv thaiv tshwj xeeb xws li stator winding overheating, bearing overheating, thiab dej nkag mus rau hauv lub cev muaj zog lossis roj chamber.
4. Ntau zaus zog-txuag tswj pib ntaus ntawv
Lub tshuab hluav taws xob submersible yog siv los ntawm qhov sib txawv ua ntej kev tswj hwm lub zog ntawm lub zog-txuag, uas muaj cov txiaj ntsig hauv qab no:
(1) Lub tshuab xa dej tuaj yeem ua haujlwm tau raws li qhov xav tau ntawm cov dej xav tau: tom qab teeb tsa cov dej siab, cov dej xa dej yuav hloov kho qhov ceev thiab cov twj tso kua dej submersible raws li qhov teeb tsa siab, kom cov dej xa dej tuaj yeem ua haujlwm tau zoo thiab lub zog -txuag lub xeev optimized.
(2) Lub tshuab xa dej tuaj yeem hloov kho qhov dej siab kom tswj tau qib tas li, tsis txhob muaj qhov hloov pauv loj hauv cov dej siab.
(3) Kev siv lub tshuab hloov pauv zaus rau kev pib muag muag tshem tawm cov surge tam sim no thaum pib thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv.
(4) Ua tiav kev tiv thaiv kev ua haujlwm: Cov cuab yeej tswj tau muaj ntau yam kev tiv thaiv xws li overload, overcurrent, xauv rotor, overvoltage, overheating, thiab lwm yam. Yog tias muaj kev ua txhaum thaum lub sij hawm ua haujlwm ntawm lub twj tso kua mis submersible, cov cuab yeej tiv thaiv yuav cia li nres kev ua haujlwm ntawm lub twj tso kua mis submersible thiab tso tawm lub tswb; Lub kaw lus tseem muaj cov haujlwm xws li kev kuaj xyuas tus kheej, kuaj xyuas qhov yuam kev, kev nco tsis raug, kev ua txhaum cai, thiab tsis siv neeg pib lub twj tso kua mis thaub qab.
