10kV siab -voltage switchgearyog ib qho tseem ceeb ntawm cov khoom siv nyob rau hauv lub zog faib hluav taws xob, lub luag haujlwm rau kev txais tos, kev faib khoom, kev tswj hwm, thiab kev tiv thaiv hluav taws xob hluav taws xob. Hauv qab no, kuv yuav rhuav tshem nws cov khoom siv tseem ceeb thiab theem nrab kom ntxaws thiab piav qhia lawv txoj haujlwm.
Core Concept Differentiation:
Cov Khoom Siv Tseem Ceeb: Cov khoom siv hluav taws xob tseem ceeb uas koom ncaj qha rau hauv tiam neeg, kev sib kis, kev faib tawm, thiab kev siv hluav taws xob hluav taws xob. Nws yog yus muaj los ntawm high voltage thiab high tam sim no. Nws yog "lub cev" ntawm lub voj voog.
Cov Khoom Siv Thib Ob: Cov cuab yeej uas saib xyuas, tswj, tiv thaiv, thiab ntsuas cov cuab yeej tseem ceeb. Nws yog tus cwj pwm los ntawm qhov tsis tshua muaj hluav taws xob thiab tsis tshua muaj tam sim no (feem ntau DC 220V / 110V, AC 220V). Nws yog "lub hlwb thiab lub paj hlwb" ntawm lub cev.
I. Cov Khoom Siv Tseem Ceeb thiab Nws Txoj Haujlwm
Cov khoom siv tseem ceeb yog ntsia rau hauv lub ntsiab busbar compartment, Circuit Court breaker compartment, thiab cable compartment ntawm lub switchgear, ua ke ua tus thawj Circuit Court.
Nqus Circuit Court Breaker (los yog SF₆ Circuit Breaker)
Muaj nuj nqi: Lub hauv paus kev khiav hauj lwm thiab kev tiv thaiv ntawm lub switchgear. Nws tuaj yeem txuas thiab txiav cov khoom thauj tam sim no raws li kev ua haujlwm ib txwm muaj; nyob rau hauv qhov tshwm sim ntawm ib tug luv luv - Circuit Court txhaum, nws tuaj yeem cuam tshuam qhov luv luv - Circuit Court tam sim no nyob rau hauv kev tswj ntawm cov khoom tiv thaiv relay. Nws arc- tua nruab nrab yog nyob rau hauv lub tshuab nqus tsev, yog li lub npe.

Tus Neeg Sawv Cev Cim: FU.
Surge Arrester (los yog Overvoltage Protector)
Muaj nuj nqi: Tiv thaiv cov khoom siv hluav taws xob hauv switchgear thiab kab los ntawm kev puas tsuaj los ntawm xob laim overvoltage lossis kev ua haujlwm overvoltage. Thaum lub overvoltage nce mus txog ib qho nqi, nws sai sai, diverting lub overvoltage zog rau hauv av.
Symbol: FV los yog A.
Fais fab Cable / Busbar
Function: Tus neeg xyuas pib uas txuas thiab xa hluav taws xob hluav taws xob. Busbars nyob rau hauv lub txee txuas ntau yam khoom thiab lub ntsiab transformer, thaum lub sij hawm tawm cables xa hluav taws xob hluav taws xob mus rau downstream faib units los yog cov neeg siv.
High-Voltage Live Indicator
Muaj nuj nqi: Pom pom seb lub hauv paus Circuit Court puas muaj zog (feem ntau nrog LED qhia) siv lub hauv paus ntsiab lus ntawm kev faib hluav taws xob. Nws kuj tseem tuaj yeem siv ua ke nrog lub ntsuas hluav taws xob electromagnetic kom ua tiav qhov yuam kev cuam tshuam, tiv thaiv kev nkag mus rau hauv cov khoom siv hluav taws xob.
II. Cov khoom siv thib ob thiab nws txoj haujlwm
Cov khoom siv thib ob feem ntau yog ntsia rau ntawm qhov ntsuas vaj huam sib luag qhov rooj ntawm lub tshuab hloov pauv lossis hauv cov khoom siv thib ob / cov khoom hauv lub txee. Qee cov cuab yeej tseem ceeb tau nruab rau ntawm cov khoom siv hluav taws xob tiv thaiv kev ywj pheej.
Relay Protection Devices (Microcomputer-Integrated Protection Devices)
Muaj nuj nqi: "lub hlwb ntse" ntawm lub switchgear. Nws sau cov cim tam sim no thiab qhov hluav taws xob los ntawm CT thiab PT hauv lub sijhawm tiag tiag thiab ua kev txiav txim siab raws li cov txheej txheem logic. Thaum muaj teeb meem xws li luv luv Circuit Court, overcurrents, overloads, thiab grounding tshwm sim, nws teeb meem commands mus rau lub Circuit Court breaker thiab teeb meem ceeb toom. Cov cuab yeej tiv thaiv niaj hnub kuj tseem suav nrog kev ntsuas, tswj, thiab kev sib txuas lus.
Kev Tiv Thaiv Hom: Kev tiv thaiv overcurrent, instantaneous overcurrent tiv thaiv, xoom-ib ntu (hauv av) tiv thaiv, tiv thaiv overload, thiab lwm yam.

Lub Zog Cia Qhov Ntsuas Teeb (Daj lossis Dawb).
Qhov taw qhia txoj hauj lwm teeb (piv txwv li, "Operating Position," "Test Position," "Grounding Position").
Relays thiab cov cuab yeej pabcuam
Intermediate Relays: Nthuav kev sib cuag muaj peev xwm thiab kom muaj nuj nqis, ua tus "choj" ntawm cov cuab yeej tiv thaiv thiab lub tshuab hluav taws xob ua haujlwm.
Lub Sijhawm Relays: Muab kev ncua ncua sijhawm.
Anti-Pump Relays: Tiv thaiv lub Circuit Court breaker los ntawm "dhia" (rov qhib thiab kaw) thaum lub teeb liab kaw tsis tu ncua, yog li tiv thaiv cov khoom siv.
Kub thiab av noo tswj: tswj lub rhaub thiab kiv cua hauv lub txee kom tiv thaiv kom tsis txhob muaj dej.

Summary Relationship Diagram
Lub 10kV switchgear tuaj yeem piv rau "tib neeg lub cev":
Cov khoom siv tseem ceeb yog cov pob txha thiab cov leeg (circuit breakers - fists, busbars - arteries, CT/PT - sensory nerve endings), lub luag hauj lwm rau load bearing thiab tua.
Cov khoom siv thib ob yog lub hlwb thiab lub paj hlwb (cov khoom siv tiv thaiv - lub hlwb, tswj circuits - hauv nruab nrab paj hlwb, teeb liab circuits - cov paj hlwb), lub luag haujlwm rau kev nkag siab, kev txiav txim siab - ua, thiab hais kom ua.
Cov khoom siv tseem ceeb yog lub hauv paus, cov khoom siv thib ob yog qhov lav. Ua haujlwm ua ke, lawv ua kom muaj kev nyab xeeb, txhim khu kev qha, ruaj khov, thiab kev ua haujlwm ntse ntawm 10kV fais fab kev faib tawm.
