Kev xaiv thiab kev sib koom tes hauv VCB

Kev xaiv thiab kev sib koom ua ke ntawm lub tshuab nqus tsev Circuit Court breakers yog ncaj qha ntsig txog kev nyab xeeb, kev cia siab, thiab kev xaiv ntawm lub tshuab fais fab. Hauv qab no, peb yuav piav qhia txog cov yam ntxwv no kom ntxaws los ntawm qhov kev xav ntawm "kev xaiv" thiab "kev sib koom tes".

Thaum xaiv lub tshuab nqus tsev vacuum breakers, ib qho kev txiav txim siab yuav tsum tau ua raws li lawv daim ntawv thov scenarios (xws li cov kab nkag hauv cov chaw nres tsheb, cov kab xa tawm, kev tiv thaiv lub cev muaj zog, thiab lwm yam) thiab cov txheej txheem tsis ua haujlwm. Cov kev ntsuas tseem ceeb hauv qab no feem ntau yog nyob ntawm:

1. Core Electrical Parameters

Rated Voltage: Nws yuav tsum muaj ntau dua lossis sib npaug rau qhov ua haujlwm siab tshaj plaws ntawm daim phiaj fais fab.

Rated Tam sim no: Nws yuav tsum muaj ntau tshaj qhov ntev tshaj plaws - lub sij hawm ua hauj lwm tam sim no ntawm Circuit Court thiab coj mus rau hauv tus account ib tug tej yam overload muaj peev xwm thiab yav tom ntej kev loj hlob margin.

Rated Short-Circuit Breaking Current: Qhov no yog ib qho ntawm qhov tseem ceeb tshaj plaws. Nws yuav tsum ntau dua los yog sib npaug rau qhov luv luv -circuit tam sim no ntawm qhov chaw teeb tsa. Qhov tam sim no yuav tsum tau muab xam los ntawm lub zog hluav taws xob luv luv - ntsuas hluav taws xob.

Rated Short-Lub Sijhawm Nrog Tam Sim No: Nws hais txog qhov muaj txiaj ntsig zoo ntawm qhov luv luv - tam sim no uas lub Circuit Court breaker tuaj yeem tiv taus nyob rau hauv lub xeev kaw hauv ib lub sijhawm (xws li 1s, 4s). Nws kuaj qhov dynamic thiab thermal stability ntawm lub Circuit Court breaker.

Rated Short-Circuit Making Current: Nws hais txog qhov siab tshaj plaws tam sim no uas lub Circuit Court breaker tuaj yeem kaw tau zoo thaum muaj qhov cuam tshuam luv luv -circuit (feem ntau yog 2.5 npaug ntawm qhov tawg tam sim no), sim nws lub peev xwm los tiv thaiv hluav taws xob dynamic cuam tshuam.

2. Mechanical and Operating Mechanism Parameters

Mechanical Life: Lub tshuab nqus tsev vacuum muaj lub neej ua haujlwm ntev heev, feem ntau tshaj 10,000 kev ua haujlwm. Kev xaiv yuav tsum yog nyob ntawm qhov zaus ntawm kev ua haujlwm.

Kev khiav hauj lwm Mechanism Hom: Caij nplooj ntoos hlav kev khiav hauj lwm mechanism (feem ntau yog siv), electromagnetic kev khiav hauj lwm mechanism, thiab lwm yam. Caij nplooj ntoos hlav mechanisms yog heev txhim khu kev qha thiab muaj tsawg yuav tsum tau rau kev khiav hauj lwm hwj chim.

3. Ib puag ncig thiab lwm yam

Installation Ib puag ncig: Sab hauv lossis sab nraum zoov? Ib puag ncig kub, av noo, qhov siab (qhov ntsuas yuav tsum tau kho rau qhov siab siab), thiab lwm yam.

Installation Method: Tsau hom lossis hom nqa nqa (hom rho tawm)? Handcart hom yog yooj yim rau kev txij nkawm thiab yog siv dav.

Hom thiab Zoo: Xaiv lub npe nrov kom paub meej cov khoom zoo thiab tom qab - kev muag khoom.

Kev sib koom tes, tseem hu ua "matching", yog lub peev xwm los xyuas kom meej tias lub tshuab nqus tsev vacuum breakers ua haujlwm hauv kev sib koom tes nrog lwm cov khoom siv tiv thaiv hauv lub cev (xws li sab sauv - theem Circuit Court breakers, qis -theem Circuit Court breakers, fuses, thiab lwm yam) kom ua tiav kev tiv thaiv xaiv. Lub hom phiaj kawg yog txhawm rau txwv qhov cuam tshuam ntawm qhov tsis raug mus rau qhov tsawg kawg nkaus thiab xyuas kom lub zog txuas ntxiv mus rau qhov tsis yog - qhov chaw txhaum. Kev sib koom tes feem ntau suav nrog cov hauv qab no:

1. Kev sib koom tes nrog Fuses

Qee qhov xwm txheej (xws li kev tiv thaiv kev hloov pauv, kev tiv thaiv capacitor), kev sib xyaw ntawm "nqus Circuit Court breaker + fuse" raug saws.

Lub Hom Phiaj: Rau qhov loj tam sim no luv luv, lub fuse muab kev tiv thaiv sai los ntawm melting; rau overcurrent, lub tshuab nqus tsev Circuit Court breaker mus nrog ib tug ncua.

Kev sib koom ua ke yuav tsum tau ua: Nws yog ib qho tsim nyog los xyuas kom meej tias nyob rau hauv ib qho tshwj xeeb tam sim no, kev khiav hauj lwm tus yam ntxwv nkhaus ntawm lub fuse thiab kev khiav hauj lwm yam ntxwv nkhaus ntawm Circuit Court breaker muaj kev sib koom tes zoo kom tsis txhob dhau - theem tripping.

2. Kev sib koom tes nrog lub peev xwm ntawm kev thauj khoom - sab khoom (kev sib koom ua ke sab nraud)

Lub Hom Phiaj: Xyuas kom meej tias thaum lub tshuab nqus tsev nqus hluav taws xob txiav tawm luv luv -circuit tam sim no, lub zog arc thiab qhov cuam tshuam tam sim no nws tsim tsis muaj kev puas tsuaj rau lub Circuit Court breaker nws tus kheej lossis lwm yam khoom siv hauv lub cev (xws li transformers, motors).

Txoj kev siv: Xaiv lub tshuab nqus tsev vacuum breakers uas tsis tshua muaj kev cuam tshuam tam sim no qhov tseem ceeb, tshwj xeeb tshaj yog thaum siv los hloov inductive loads (xws li motors, transformers), kom tsis txhob ua haujlwm overvoltage.

Kev xaiv yog lub hauv paus: Nruab txhua lub ntsiab lus nrog qhov tsim nyog "tub rog" (circuit breaker).

Kev sib koom tes yog qhov kev tawm tsam: Cia cov "cov tub rog" ua haujlwm hauv kev sib koom ua ke los tsim txoj kab tiv thaiv sib sib zog nqus, tsis yog them nyiaj dig muag lossis sib ntaus ib leeg.

Hauv kev tsim vaj tsev tiag tiag, kev xaiv thiab kev sib koom ua ke ntawm lub tshuab nqus tsev vacuum breakers yog ib txoj haujlwm ua haujlwm, feem ntau yuav tsum tau siv cov kws tshaj lij luv luv -circuit xam software thiab kev tiv thaiv kev sib koom tes nkhaus tsom xam software kom tiav, kom ntseeg tau tias lub zog hluav taws xob muaj kev nyab xeeb thiab txhim khu kev qha.

ZW32-12 Sab nraum zoov Nqus Circuit Court Breaker(tom qab no hu ua "circuit breaker") yog peb -theem AC 50Hz sab nraum zoov high voltage switchgear feem ntau yog siv nyob rau hauv 10kV sab nraum zoov tis systems ntawm cov nyob deb nroog thiab nroog, raws li ib tug txhais tau tias ntawm tawg thiab kaw load tam sim no, overload tam sim no, thiab luv luv -circuit tam sim no; Nws kuj tseem tuaj yeem siv rau hauv lwm qhov chaw zoo sib xws; Cov yam ntxwv ntawm cov qauv: Lub Circuit Court breaker muaj peb - theem pillars thiab ib qho kev khiav hauj lwm mechanism, nrog ib tug yooj yim qauv. Tus ncej txais epoxy resin khoom rwb thaiv tsev, uas muaj qhov zoo ntawm qhov kub thiab txias tsis kam, UV tsis kam, thiab kev laus ua haujlwm; Circuit Court breaker kev ua tau zoo: E2-C2-M2.
