Akpachara anya maka nha ihe mkpuchi nke Generator

Ndị na-emepụta ndị ọkachamara na-agụnye ọtụtụ ihe ọmụma ọkachamara, otu n'ime ha bụ nyocha mkpuchi nke ndị na-emepụta ọkụ. Taa, m ga-ewebata gị ule mkpuchi nke ndị na-emepụta ihe na ihe ndị chọrọ nlebara anya.

A na-ekewa ihe mkpuchi nke generator na ihe abụọ: mkpuchi stator na mkpuchi rotor.

Mkpuchi Stator

Ebe nha nke stator mkpuchi dị na generator na-anọpụ iche grounding kabinet. Enwere ike tụọ mkpuchi stator naanị mgbe rotor nọ n'ọnọdụ kwụ ọtọ ma ọ bụ mgbochi, a na-ebo onye na-emepụta ihe na hydrogen ka ọ̀tụ̀tụ̀ nrụgide a tụrụ anya ya, etinyere stator mmiri jụrụ oyi n'ọrụ, na conductivity nke mmiri jụrụ oyi dị gburugburu 0.2 μS / cm.

#1, a ga-akwụsị ebe mgbaba nke generator na-anọpụ iche, a ga-ewepụkwa generator PT trolley. Mgbe ahụ, a na-eji ihe nleba anya mkpuchi mkpuchi 1000V (megohmmeter) maka nha. A na-ewere ya dị ka onye ruru eru mgbe mkpuchi n'etiti oge na ala adịghị erughị 1MΩ.

# 2, ihe mgbakwasị ụkwụ nke ndị na-agbanwe voltaji na generator na-anọpụ iche na ihe ntụgharị ọkụ ọkụ na-anọpụ iche kwesịrị ịkwụsị, a ga-ewepụkwa generator PT trolley. Mgbe ahụ, a na-eji ihe nleba anya mkpuchi mkpuchi 2500V maka nha. Oge ngwa voltaji maka nha bụ 1 nkeji. Mgbe okpomọkụ dị n'okpuru 20 ℃, mkpuchi n'etiti oge na ala ekwesịghị ịbụ ihe na-erughị 0.5MΩ, na nke ọ bụla na-adọ kwesịrị tụrụ otu ugboro na atọ-phase yiri ala. Ọ bụrụ na ọnụ ahịa atụtara dị ala karịa 80% nke uru dị n'elu ma ọ bụ ọdịiche dị na ụkpụrụ mkpuchi n'etiti usoro karịrị 20%, mkpuchi ahụ erughị eru.

# 3, # 4, # 5, na grounding mma mgba ọkụ nke generator na-anọpụ iche kwesịrị ịdọrọ, na generator PT trolley kwesịrị ịdọrọ. Mgbe ahụ, a na-eji ihe nleba anya mkpuchi mkpuchi 1000V maka nha. A na-ewere ya dị ka onye ruru eru mgbe mkpuchi n'etiti oge na ala adịghị erughị 0.8MΩ.

Ntụnye mkpuchi mkpuchi rotor

Maka nkeji #1, jiri ihe nleba anya mkpuchi mkpuchi 500V (megohmmeter). Ihe mgbochi mkpuchi na ala kwesịrị ịdị karịa 20MΩ.

A na-eme nha mkpuchi mkpuchi rotor nke Unit #2 site na ndị ọrụ ndozi. Ọ na-achọrọ na ikpuchi iguzogide ala dị ukwuu karịa 100MΩ na 20 ℃ na karịa 50MΩ na 30 ℃.

Maka nkeji #3, nkeji #4 na nkeji #5, jiri ihe nleba anya mkpuchi mkpuchi 500V. Ihe mgbochi mkpuchi na ala kwesịrị ịdị karịa 1MΩ.

Akpachara anya maka nha ihe mkpuchi nke Generator

1) N'oge usoro ngbanwe nke gas na ịgbanye ma gbanyụọ ule nke generator-transformer unit switches, a machibidoro iwu ịlele mkpuchi nke akụkụ niile nke generator.

2) Ejila ihe nleba anya mkpuchi mkpuchi iji tụọ nguzogide mkpuchi nke akụkụ njikwa na ngwaọrụ eletrọnịkị nke kabinet rectifier. Ọ bụrụ na nha dị mkpa, ndị ọrụ ọkachamara kwesịrị ime ya.

3) Jikọọ wiring nke megohmmeter mmiri nke ọma iji gbochie mmebi megohmmeter mmiri.

4) Ekwesịrị ịgbado ọkpọkọ ọkpọkọ nke stator mmiri jụrụ oyi (ọnụ 94, 95, 96).

5) Mgbe ị na-atụle mkpuchi nke isi rotor exciter nke Unit #1 na Unit #2, a ga-agbanye ngbanwe nchọpụta mkpuchi nke rotor isi exciter na ọnọdụ nke (imemulation maka Unit #2) (ule maka nkeji #1).

6) Mgbe ị na-atụle rotor mkpuchi nke Generator #3 na Generator # 4, na rotor grounding fuse na rotor voltaji kewapụ fuse kwesịrị dọpụrụ oghe. Ma ọ bụghị ya, fuse nwere ike ịfụ.

7) Tupu ịlele mkpuchi nke obere voltaji akụkụ winding nke excitation transformer, fuses nke DC capacitor, inyeaka transformer na synchronous transformer na rectifier kabinet kwesịrị ịdọrọ oghe.

8) Mgbe ị na-atụle ihe mkpuchi nke generator-transformer unit, nkwụsị nkwụsị nkwụsị nke isi ihe na-agbanwe agbanwe na alaka ụlọ ọrụ nke ihe ntanetị ọrụ voltaji dị elu kwesịrị ịdị na-emeghe, na generator outlet PT kwesịrị ịnọ n'ọnọdụ a kwụsịrị.

9) A na-ahapụ ya ka ịlele mkpuchi nke generator mgbe rotor generator nọ na nkwụsị ma ọ bụ nkwụsị iji gbochie ọkụ eletrik na ndị ọrụ ma ọ bụ mebie megohmmeter mmiri.
