Tsawg & nruab nrab voltage paralleling switchgear

Switchgear yog ib lub ntsiab lus dav uas piav txog ntau yam kev hloov khoom siv uas txhua tus ua tiav ib qho kev xav tau: tswj, tiv thaiv, thiab cais lub zog.Txawm hais tias qhov kev txhais no yuav raug ncua kom suav nrog cov khoom siv los tswj thiab ntsuas lub zog hluav taws xob, cov hluav taws xob hluav taws xob, thiab cov cuab yeej zoo sib xws.

Circuits yog tsim los tswj cov nqi hluav taws xob tsawg, thiab thaum lub sijhawm tam sim no dhau mus, nws tuaj yeem ua rau cov xaim hluav taws xob dhau los.Qhov no yuav ua rau cov khoom siv hluav taws xob puas tsuaj, lossis ua rau hluav taws kub.Switchgears yog tsim los tiv thaiv cov cuab yeej txuas nrog lub zog hluav taws xob los ntawm kev hem thawj ntawm hluav taws xob overload.

Nyob rau hauv cov kev tshwm sim ntawm ib tug hluav taws xob surges, ib tug zoo switchgear yuav ua rau, cia li cuam tshuam lub ndlwg ntawm lub hwj chim thiab tiv thaiv cov hluav taws xob systems ntawm kev puas tsuaj.Switchgears kuj tseem siv rau cov khoom siv de-energizing rau kev kuaj kev nyab xeeb, kev saib xyuas, thiab kev ua txhaum.

Muaj peb chav sib txawv ntawm cov tshuab hluav taws xob hloov pauv: qis-voltage, nruab nrab-voltage, thiab high-voltage.Txhawm rau txiav txim siab seb qhov system switchgear twg yog qhov zoo rau koj kom phim qhov tsim hluav taws xob ntawm txhua qhov system mus rau qhov ntsuas hluav taws xob ntawm lub switchgear.

1. High-Voltage Switchgears
High-voltage switchgears yog cov uas tswj 75KV ntawm lub hwj chim lossis ntau dua.Vim tias cov breakers no yog tsim los rau kev siv high-voltage, lawv feem ntau suav nrog kev txhim kho kev nyab xeeb.

2. Nruab nrab-Voltage Switchgear
Nruab nrab-voltage switchgear yog siv nyob rau hauv cov tshuab los ntawm 1KV txog 75KV.Qhov no switchgear feem ntau pom nyob rau hauv cov tshuab uas muaj motors, feeder circuits, generators, thiab kis tau tus mob thiab tis kab.

3. Tsawg-voltage Switchgear
Tsawg-voltage switchgear yog tsim los tswj cov tshuab txog li 1KV.Cov no feem ntau pom muaj nyob rau sab qis-voltage ntawm cov hluav taws xob faib hluav taws xob thiab siv thoob plaws ntau yam kev lag luam.

Los ntawm kev ua tib zoo xav txog qhov muaj qhov sib txawv, kev nkag mus rau cable thiab cov kev xav tau ntawm kev teeb tsa, peb tuaj yeem tsim, tsim khoom thiab nruab cov tswj vaj huam sib luag hauv ntau cov duab, qhov ntau thiab tsawg thiab kev npaj kom haum rau txhua qhov kev txwv.Peb tuaj yeem muab lub sijhawm luv luv thiab tus nqi tsim nyog tshaj plaws rau cov khoom siv hluav taws xob uas tsim thiab tsim kom ua raws li cov lus qhia tshwj xeeb lossis cov kev cai tshwj xeeb.
