Yiziphi izivikelo zikagesi ezinhlanu ze-switchgear ene-voltage ephezulu?

Umqondo wokuvimbela okuyisihlanu:

1. Isinqamuleli sokuvula nokuvala sokuvala umthwalo;

2. Vimbela ukuvulwa okungamanga nokuvalwa kwe-circuit breaker;

3. Iswishi yokuvala i-anti-load yokuvala;

4. Ukudluliswa kwemithwalo lapho iswishi evimbela ukugxilisa ivaliwe;

5. Vimbela ukungena endaweni ebukhoma ngephutha.

Ilokhi yokuvikela emihlanu iyisethi yokukhiya efakwe ukuze kuzuzwe izinyathelo zokuvimbela ezinhlanu ezingenhla.Ukuze kuzuzwe umsebenzi othize wokuvimbela okuhlanu, kudinga futhi ukusebenzisana ne-microcomputer uhlelo lokuvimbela kahlanu noma ngokusebenzisa imithetho eqinile yokusebenza yokuvimbela emihlanu yabasebenzi.

"Izinyathelo ezinhlanu zikagesi" ze-high-voltage switchgear:

"Ukuxhuma" kwe-switchgear ephezulu kuyisinyathelo esibalulekile sokuqinisekisa ukusebenza okuphephile kwegridi yamandla, ukuqinisekisa ukuphepha kwemishini nabasebenzi, nokuvimbela ukusetshenziswa kabi.I-GB3906-1991 “3~35 kV AC Metal-enclosed Switchgear” yenze izinhlinzeko ezicacile zalokhu.Ngokuvamile, "i-interlocking" ichazwa ngokuthi: ukuvimbela ukuvulwa okungamanga nokuvalwa kwe-circuit breaker;ukuvimbela ukuvulwa nokuvalwa kwe-disconnector ngomthwalo;ukuvimbela ukulengiswa (ukuvala) kocingo oluphansi (i-grounding switch) ngamandla;ukuvimbela ukuvala ucingo oluphansi (switch) ngamandla;ukuvimbela ukungena endaweni ebukhoma ngephutha.Okuqukethwe okungenhla okuhlanu ukuvimbela ukusetshenziswa kabi kukagesi kubizwa ngokuthi "izivimbelo ezinhlanu"."Izivimbelo ezinhlanu" Amadivayisi ngokuvamile ahlukaniswa ngezigaba zemishini, zikagesi kanye neziphelele.Njengamanje, kunezinhlobo eziningi zama-switchgear ane-voltage ephezulu emakethe, iningi lazo elinemodi yokuxhuma i-shaft ephelele.

1. Ngemuva kokuthi i-vacuum circuit breaker trolley ku-high-voltage switch cabinet ivaliwe endaweni yokuhlola, i-breaker circuit ye-trolley ayikwazi ukungena endaweni yokusebenza.(Vimbela ukuvala ngomthwalo).

2. Uma umshini wokumisa phansi kukhabhinethi yokuguqula i-high-voltage ivaliwe, i-breaker circuit trolley ayikwazi ukuvalwa.(Vimbela ukuvala ngocingo oluphansi).

3. Lapho i-vacuum circuit breaker ku-switchgear ene-voltage ephezulu ivaliwe, umnyango ongemuva wephaneli kanye nekhabhinethi ukhiywa ngomnyango wekhabhinethi ngomshini ophezu kombese ophansi.(Vimbela ukungena endaweni ebukhoma ngephutha).

4. I-vacuum circuit breaker ku-high-voltage switch cabinet ivaliwe ngesikhathi sokusebenza, futhi inkinobho yokuvala phansi ayikwazi ukufakwa ekusebenzeni.(Vimbela ukulengiswa bukhoma kocingo oluphansi).

5. I-vacuum circuit breaker ku-high-voltage switch cabinet ayikwazi ukuphuma endaweni yokusebenza ye-trolley circuit breaker uma ivaliwe.
