Yuav ua li cas kom txo tau qhov tshwm sim ntawm siab thiab qis voltage Switchgear tsis ua hauj lwm?

https://www.kaichuanpower.com/

High thiab low voltage switchgear feem ntau muaj qhov ua txhaum loj thiab me me hauv peb niaj hnub siv, xws li kuv qhov siab thiab qis voltage switchgear tom qab peb tau siv ntev, nws yuav ua rau tsis ua haujlwm ntawm lub switchgear vim kev ua haujlwm tsis raug thiab lwm yam, uas muaj kev cuam tshuam zoo rau kev siv tag nrho, yog li tsis muaj txoj hauv kev kom tsis txhob muaj cov kev ua tsis tiav no, lossis kev ntsuas los txo qhov kev puas tsuaj ntawm qhov siab thiab qis voltage switchgear. Tom ntej no, kuv yuav coj koj los piav qhia meej - cov ntsiab lus hauv qab no hauv qhov no.

1. Kuv qhov siab thiab tsis tshua muaj hluav taws xob hloov pauv tsis ua haujlwm tshwm sim los ntawm qhov kub thiab txias:

Cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob hauv cov mining siab thiab tsis tshua muaj hluav taws xob hloov hluav taws xob yog tsim los ntawm fuses, AC contactors, residual tam sim no tiv thaiv, capacitors thiab meters. Cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob no tau tsim thiab tsim ua raws li Cov Qauv Txheej Txheem rau Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob, thiab lawv cov kev ua haujlwm ib txwm raug teev tseg raws li: qhov txwv sab saud ntawm cov huab cua ambient kub tsis tshaj 40. Qhov nruab nrab tus nqi ntawm cov khoom siv hluav taws xob tsawg. ambient cua kub rau 24h tsis tshaj 35, thiab qhov qis tshaj ntawm cov huab cua kub tsis tsawg tshaj -5 los yog -25. Lub switchgear ntawm kev hloov pauv hauv cov neeg nyob deb nroog tau ua haujlwm sab nraum zoov, nws tsis yog tsuas yog ncaj qha irradiated los ntawm lub hnub ci los ua qhov kub thiab txias, tab sis kuj ua kom sov hauv kev ua haujlwm, yog li nyob rau lub caij kub kub ntawm lub caij ntuj sov, qhov kub ntawm lub thawv switchgear yuav ncav cuag. ntau tshaj 60, thiab qhov kub ntawm lub sij hawm no zoo heev tshaj qhov kub thiab txias ambient teev los ntawm cov khoom siv hluav taws xob, ces qhov txhaum tshwm sim los ntawm overheating ntawm cov hluav taws xob Cheebtsam nyob rau hauv lub switchgear yuav tshwm sim.

2. Kev ua tsis tiav los ntawm cov khoom zoo:

Nyob rau hauv kev hloov pauv ntawm cov kab hluav taws xob nyob deb nroog, vim qhov kev thov rau siab thiab tsis tshua muaj hluav taws xob hloov hluav taws xob hauv mine yog qhov loj heev, tab sis lub sijhawm tsim kho luv luv, lub thawv xa khoom yuav tsum tau muab cov khoom siv hluav taws xob tsawg tsawg nrawm thiab nyob rau hauv ntau qhov ntau, yog li yuav muaj qhov tshwm sim uas yuav tsum muaj rau cov khoom lag luam zoo tsis nruj, thiab tom qab ntawd yuav muaj qhov tsis ua tiav sai tom qab cov khoom raug muab tso rau hauv kev ua haujlwm. Piv txwv li, qee hom AC contactors tsis tuaj yeem ua haujlwm sai tom qab lub thawv xa khoom tau muab tso rau hauv kev ua haujlwm vim tias cov contactor kaw coil raug hlawv.

3. Qhov tsis ua hauj lwm ntawm mine qhov siab thiab qis voltage switchgear tshwm sim los ntawm kev xaiv tsis raug ntawm cov khoom siv hluav taws xob

Vim qhov kev xaiv tsis raug ntawm AC contactor muaj peev xwm thaum tsim khoom, AC contactors ntawm tib lub peev xwm raug teeb tsa rau cov hluav taws xob sib txawv, thiab qhov tsis sib xws ntawm peb-theem load tsis raug txiav txim siab, thiab theem tam sim no ntawm ib feem ntawm qhov hluav taws xob contactor tsis zoo dua. raws li cov qauv xaiv ib txwm, uas tseem ua rau kub hnyiab tawm ntawm AC contactors thaum ua haujlwm hauv lub caij ntuj sov kub hauv lub caij ntuj sov.

Raws li cov saum toj no, peb paub qhov ua rau ntawm qhov tsis ua hauj lwm, ces nws yog ib qho yooj yim mus ua, piv txwv li, thawj yog vim muaj kev cuam tshuam ntawm ambient kub, ces nws yog tsim nyog los xaiv high-temperature resistant khoom los yog ib co kev kho cua txias. nyob rau lub sijhawm raws li qhov xav tau, thiab qhov thib ob yog qhov peb yuav tsum ua tib zoo tshuaj xyuas nws ua ntej siv los txiav txim siab tias qhov zoo tsis muaj teeb meem hauv kev yuav khoom thiab siv, thiab peb tsis tuaj yeem xaiv qhov muag tsis pom. Tsis tas li ntawd, thaum peb siv lub siab thiab qis voltage switchgear rau mining, peb yuav tsum siv nws raws li cov lus qhia ua haujlwm, thiaj li yuav txo tau qhov tshwm sim ntawm kev ua tsis tiav.
