CT (Tam sim no Transformer) piv rau PT (Tam sim no Transformer)

Txawm hais tias ob qho tib si tam sim no transformers (CT) thiab voltage transformers (PT / VT) yog cais raws li transformers, lawv cov dej num thiab daim ntawv thov scenarios txawv heev. Hauv qhov teeb meem no, peb yuav pib nrog lawv cov ntsiab lus tseem ceeb los tshawb txog lawv lub luag haujlwm, kev ua haujlwm thiab cov xwm txheej siv tau.

 

CT (Tam sim no Transformer)

 

Tswv yim

Tam sim no transformer (CT) yog ib qho khoom siv hluav taws xob inductive. Los ntawm electromagnetic induction, nws nqis los ntawm qhov siab thawj tam sim no mus rau tus qauv qis theem nrab tam sim no (1A lossis 5A) ntawm qhov sib piv ruaj khov, thaum muab kev sib cais galvanic ntawm qhov siab -voltage main circuit and secondary control thiab

cov cuab yeej ntsuas.

 

 

Muaj nuj nqi

• Ntsuas & Metering:Cov kauj ruam cia siab load tam sim no rau hauv cov qauv teeb liab tam sim no rau ammeters, lub zog ntsuas hluav taws xob thiab lub zog ntsuas hluav taws xob, ua kom ntsuas qhov ntsuas tam sim no thiab hluav taws xob.

 

• Kev Tiv Thaiv Relay:Muab cov teeb liab tam sim no rau microcomputer tiv thaiv cov cuab yeej kom paub txog kev thauj khoom ntau dhau, luv- Circuit Court thiab tiv thaiv kev ua txhaum ntawm cov kab hluav taws xob thiab khoom siv.

 

• Hluav taws xob cais:cais cov hluav taws xob siab thiab hnyav tam sim no, ua kom muaj kev nyab xeeb ntawm kev ntsuas, tswj cov khoom siv thiab ntawm - cov neeg ua haujlwm tu tsev.

 

• Standardized Interface:Kev sib koom ua ke cov khoom tsim tawm theem nrab kom ua tiav universal compatibility ntawm kev ntsuas, saib xyuas thiab tiv thaiv cov cuab yeej.

 

Daim Ntawv Thov Scope

Nws yog dav siv nyob rau hauv 10kV siab-voltage switchgear, lub nplhaib tseem ceeb units, lub thawv-hom transformers thiab qis-voltage tis txee. Nws kuj yog siv nyob rau hauv thawj thiab theem nrab circuits ntawm lub hwj chim transformers, lub cev muaj zog feeders, thiab tag nrho cov fais fab mov circuits uas yuav tsum tau tam sim no saib xyuas thiab tiv thaiv functions.

 

Qhov voltage transformer (PT / VT)

Tswv yim

Lub tshuab hluav taws xob hloov hluav taws xob (VT / PT) yog cov khoom siv hluav taws xob tshwj xeeb. Nws proportionally nqis siab voltage mus rau ib tug standardized low voltage ntawm ib tug ruaj transformation piv. Lub ntsiab winding txuas nrog rau qhov sib npaug mus rau qhov siab -voltage main circuit, nrog rau sab thib ob xa cov qauv tso tawm ntawm 100V. Kev siv tib lub hauv paus ntsiab lus ua haujlwm raws li cov qauv hloov pauv, nws ua haujlwm rau ob qho tib si txo qis thiab siab -voltage hluav taws xob cais.

 

• Kev ntsuas hluav taws xob:Muab cov cim hluav taws xob rau voltmeters thiab zaus ntsuas ntsuas rau qhov tiag -lub sij hawm busbar voltage xyuas.

 

• Energy Metering & Billing:Koom tes nrog cov ntsuas hluav taws xob hluav taws xob los ntsuas kev siv hluav taws xob ntawm cov kab hluav taws xob siab.

 

• Kev Tiv Thaiv Relay & Saib Xyuas:Muab cov lus tawm tswv yim voltage los qhib kev tiv thaiv kev tiv thaiv overvoltage, undervoltage, theem poob thiab xoom- qhov tsis sib xws ntawm qhov voltage.

 

• Siab -Voltage Isolation:Cov kauj ruam qis qis qis mus rau qhov muaj kev nyab xeeb 100V theem nrab voltage, ua kom muaj kev ruaj ntseg thiab kev saib xyuas yooj yim ntawm ob lub voj voog.

 

• Rwb thaiv tsev saib xyuas:Tshawb pom kab hauv ntiaj teb ua txhaum hauv siab -voltage distribution systems.

 

Daim Ntawv Thov Scope

Nws yog dav siv nyob rau hauv 10kV busbar txee, PT txee, metering txee, siab -voltage nkag thiab tawm switchgears, substations thiab box- hom transformers. Cov cuab yeej no tsim nyog rau txhua qhov siab -voltage chaw uas xav tau kev saib xyuas hluav taws xob, siab -voltage metering thiab kev tiv thaiv hluav taws xob zoo.

 

 

Txhawm rau muab cov ntsiab lus pom tseeb, cov lus hauv qab no piv CT thiab PT raws li cov qauv qub.
