Cov Ntsiab Cai Ua Haujlwm ntawm Kev Rho Tawm Cov Khawm thiab Cov Transformers thiab Cov Ntsiab Cai ntawm Kev Tshuaj Xyuas Hluav Taws Xob thiab Kev Sib Tsoo Hauv Av

Ua ntej. Lub hauv paus ntsiab lus ntawm kev rho tawm qhov hloov pauv

1. Txwv tsis pub siv lub qhov hloov cais los rub cov khoom siv thauj khoom lossis cov kab thauj khoom.

2. Nws raug txwv tsis pub qhib thiab kaw lub transformer tseem ceeb uas tsis muaj load nrog lub qhov hloov cais.

3. Cov haujlwm hauv qab no raug tso cai siv lub qhov hloov cais:

a) Qhib thiab kaw lub voltage transformer thiab lightning arrester yam tsis muaj qhov txhaum;

b) Thaum tsis muaj qhov txhaum hauv lub kaw lus, qhib thiab kaw qhov nruab nrab ntawm lub transformer;

c) Qhib thiab kaw lub voj voog tam sim no yam tsis muaj impedance;

d) Qhov qhib thiab kaw voltage tuaj yeem yog 10KV thiab qis dua nrog sab nraum zoov triple disconnect switch,

Thauj khoom tam sim no hauv qab 9A; thaum nws tshaj qhov ntau saum toj no, nws yuav tsum dhau

Kev suav, kev sim, thiab kev pom zoo los ntawm tus thawj coj ua haujlwm ntawm chav tsev uas saib xyuas.

Qhov thib ob. Cov Ntsiab Cai ntawm Kev Ua Haujlwm Transformer

1. Cov xwm txheej rau kev ua haujlwm sib luag ntawm cov transformers:

a) Qhov piv ntawm qhov hluav taws xob yog tib yam;

b) Lub zog impedance yog tib yam;

c) Pawg xov hlau zoo ib yam.

2. Cov transformers nrog cov impedance voltages sib txawv yuav tsum tau suav nrog thiab tuaj yeem ua haujlwm ua ke hauv qab qhov xwm txheej uas tsis muaj ib qho ntawm lawv raug overloaded.

3. Kev ua haujlwm ntawm lub zog hluav taws xob transformer:

a) Rau kev ua haujlwm tua hluav taws xob, sab qis-voltage yuav tsum raug nres ua ntej, sab nruab nrab-voltage yuav tsum raug nres, thiab sab siab-voltage yuav tsum raug nres zaum kawg;

b) Thaum hloov lub transformer, nws yuav tsum tau lees paub tias lub transformer uas yuav tsum nres tsuas yog tuaj yeem nres tom qab lub transformer uas tau muab tso rau hauv.

4. Transformer neutral point grounding switch ua haujlwm:

a) Hauv 110KV thiab siab dua qhov nruab nrab taw tes ncaj qha rau hauv av, thaum lub transformer nres, xa hluav taws xob thiab them lub tsheb npav los ntawm lub transformer, qhov nruab nrab taw tes av hloov yuav tsum kaw ua ntej ua haujlwm, thiab tom qab ua tiav kev ua haujlwm, nws tau txiav txim siab seb puas yuav qhib raws li qhov yuav tsum tau ua ntawm lub kaw lus.；

b) Thaum lub qhov hluav taws xob nruab nrab ntawm lub transformer ua haujlwm sib luag yuav tsum tau hloov los ntawm ib qho mus rau lwm lub transformer ua haujlwm, lub qhov hluav taws xob nruab nrab ntawm lwm lub transformer yuav tsum kaw ua ntej, thiab lub qhov hluav taws xob nruab nrab qub yuav tsum qhib.；

c) Yog tias qhov chaw nruab nrab ntawm lub transformer khiav nrog lub kauj arc suppression, thaum lub transformer tsis muaj zog, lub qhov hloov cais qhov nruab nrab yuav tsum qhib ua ntej. Thaum lub transformer ua haujlwm, qhov kev txiav tawm fais fab yog ib theem; txwv tsis pub xa lub transformer nrog lub qhov hloov cais qhov nruab nrab. Tua lub qhov hloov cais qhov nruab nrab tom qab tua lub transformer ua ntej.

Qhov thib peb, lub hauv paus ntsiab lus ntawm kev tshuaj xyuas hluav taws xob grounding
1. Ua ntej sim cov khoom siv fais fab, ntxiv rau kev lees paub tias lub tshuab hluav taws xob tseem zoo thiab ua haujlwm tau zoo, yuav tsum kuaj xyuas lub tswb ceeb toom kom raug ntawm cov khoom siv nyob ntawm qib voltage sib xws ua ntej ua qhov kev sim hluav taws xob ntawm cov khoom siv uas yuav tsum tau grounded. Nws raug txwv tsis pub siv cov tshuab hluav taws xob uas tsis sib xws rau qib voltage rau kev sim hluav taws xob.
2. Thaum cov khoom siv hluav taws xob yuav tsum tau grounded, qhov hluav taws xob yuav tsum tau kuaj xyuas ua ntej, thiab lub qhov hloov grounding tuaj yeem qhib lossis lub xaim grounding tuaj yeem ntsia tau tom qab nws tau lees paub tias tsis muaj hluav taws xob.
3. Yuav tsum muaj qhov chaw meej rau kev tshuaj xyuas hluav taws xob thiab kev teeb tsa ntawm cov hlau av, thiab qhov chaw ntawm kev teeb tsa ntawm cov hlau av lossis lub qhov hloov av yuav tsum sib xws nrog qhov chaw tshuaj xyuas hluav taws xob.
4. Thaum txhim kho cov xov hlau av, av nws rau ntawm lub pob av tshwj xeeb ua ntej, thiab tshem nws tawm hauv qhov kev txiav txim rov qab ntawm qhov kawg ntawm tus neeg xyuas hluav taws xob. Nws raug txwv tsis pub txhim kho cov xov hlau av los ntawm txoj kev winding. Thaum nws tsim nyog siv ntaiv, nws raug txwv tsis pub siv ntaiv khoom siv hlau.
5. Thaum kuaj xyuas qhov hluav taws xob ntawm lub capacitor bank, nws yuav tsum tau ua tom qab kev tso tawm tiav lawm.
