Arrester installation qhov chaw
① Qhov nruab nrab point ntawm lub transformer ntsia nyob rau hauv lub high-tam sim no grounding system ntawm lub transformer nruab nrab point grounding system yog tsis grounded. Thaum lub hauv paus kev sib cais hauv av ua haujlwm nrog ib-theem grounding, qhov sib txawv ntawm kev tiv thaiv transformer yuav tsum tau txuas nrog tib lub sijhawm nrog tus ntes. Rau cov transformers nrog arc suppression coils txuas nrog qhov nruab nrab ntawm qhov nruab nrab, yog tias ib-theem tuaj yeem ua haujlwm tau ua tau, lub teeb ntes hluav taws xob yuav tsum tau nruab rau ntawm qhov nruab nrab.
②Nruam rau ntawm lub siab-voltage sab ntawm lub transformer tis, ib tug xob ntes yuav tsum tau muab ntsia rau ntawm high-voltage sab ntawm lub transformer tis, uas yog kev cob cog rua nyob rau hauv parallel nrog lub tis transformer, lub Upper kawg yog txuas nrog rau kab, thiab cov qis kawg yog grounded. Tsis tas li ntawd, raws li "Technical Regulations for Design of Overhead Distribution Lines", cov cuab yeej ntes yuav tsum tau muab tso rau ze li sai tau rau lub transformer. Nws feem ntau suav hais tias qhov kev ncua deb yuav tsum tsis pub tshaj 10m.
③ Thaum tus ntes raug ntsia rau ntawm qhov hluav taws xob qis ntawm sab qis ntawm lub tshuab hluav taws xob faib hluav taws xob, thaum lub siab hluav taws xob sab ntes tawm tawm thiab lub peev xwm ntawm cov cuab yeej hauv av nce mus rau qee tus nqi, qhov tsawg-voltage sab ntes pib tawm, yog li ntawd qhov qis-voltage sab winding qhov hluav taws xob kawg txuas nrog nws qhov nruab nrab nruab nrab thiab lub plhaub sab nraud. Qhov sib txawv muaj peev xwm txo qis.
④ Lub ntsuas hluav taws xob qis nruab rau sab qis ntawm lub thawv xa khoom yuav tsum tau nruab nruab nrab ntawm AC contactor thiab cov fuse tawm ntawm sab qis ntawm lub thawv xa khoom, thiab cov xaim hauv av yuav tsum dhau los ntawm xoom-sequence. transformer ntawm residual tam sim no qhov kev tiv thaiv. soj ntsuam.
⑤ Lwm yam Rau cov neeg siv tseem ceeb, nws raug nquahu kom nruab ib pab pawg ntawm cov neeg tua hluav taws tsawg 50m ua ntej kev taw qhia cov kab hluav taws xob qis rau hauv chav tsev, thiab tom qab ntawd nruab ib pab pawg ntawm cov neeg tua hluav taws tsawg tom qab nkag mus rau hauv chav; rau cov neeg siv dav dav, nruab ib pab pawg ntawm cov neeg tua hluav taws tsawg ntawm thawj qhov kev txhawb nqa ntawm cov khoom siv hluav taws xob qis hluav taws xob hluav taws xob; Rau cov cheeb tsam uas muaj kev cuam tshuam rau xob laim, cov neeg tua hluav taws tsawg yuav tsum tau nruab rau cov motors lossis watt-teev meters ncaj qha txuas nrog cov kab hluav taws xob.
Qhov ntsuas hluav taws xob ntawm tus ntes Lub ntsuas hluav taws xob ntawm tus ntes
Qhov siab tshaj plaws uas tso cai rau lub hwj chim zaus voltage muaj txiaj ntsig zoo ntawm qhov nruab nrab ntawm qhov nruab nrab thiab qis ntawm tus neeg ntes tau txiav txim siab los ntawm kev txiav txim siab load, tus neeg ntes yuav tsum ua haujlwm ib txwm nyob hauv qhov hluav taws xob no. Tus ntes tuaj yeem muab faib ua peb pawg raws li tus nqi ntsuas hluav taws xob:
①High voltage qeb: yog hais txog cov zinc oxide ntes nrog qib ntawm 66KV lossis siab dua, uas tuaj yeem faib ua plaub qib: 500kV, 220kV, 110kV, thiab 66kV.
② Nruab nrab voltage qeb: yog hais txog series ntawm zinc oxide ntes nyob rau hauv thaj tsam ntawm 3kV ~ 66kV (tsis suav nrog 66kV series khoom), uas tuaj yeem muab faib ua plaub theem: 3kV, 6kV, 10kV, thiab 35KV.
③ Tsawg voltage qeb: yog hais txog cov zinc oxide ntes hauv qab 3KV (tsis suav nrog 3kV series cov khoom), uas tuaj yeem muab faib ua plaub theem: 1kV, 0.5kV, 0.38kV, thiab 0.22kV.
