Maimaituji na Maimakon Farko na Tsarin Karamin Kirkiro 110kV: Maisuka da Ayyuka

1. Bayani

• Matsayin mutanen da zaka so kuɗi da ke cikin hanyar irin, za su iya kawo da duka biyu: matsayin gaba da matsayin da yake. Bayanan statistiki sun nuna cewa mafi yawan matsayin kuɗi na gaba (wanda ake yi saboda tsaye, abubuwa da fadada, kamar haka), ta shahara da shekaru 90% daga dukkan matsayin. Saboda haka, ba a yi karfin da ya fi shiga saboda matsayin, a yi karkashin daidai ya taimaka wajen zama masu amfani da juna da kyau. Yadda ake yi karfin daidai waɗanda ake yi karfin saboda matsayin an sanya auto-reclosing.

• Ba a yi karfin daidai don in bota circuit breaker:Idan matsayin gaba a cikin kuɗi ya ƙasa (kamar haka, tsaye ya haɗa, abubuwan da suka yi matsayin suka rasa), zaɓuɓɓukan da suke magana ba suza magana sosai, kuma na'urar daidai ya zo ne daidai.Idan ana matsayin da yake (kamar haka, ƙaramin kuɗi ya haɗa, ake yi idon da ke cikin kuɗi), matsayin ya ƙare bayan a yi karfin, kuma zaɓuɓɓukan za su yi karfin circuit breaker daidai.

• Yadda ake yi auto-reclosing:

• Line no-voltage check

• Synchronism check (wanda ake yi alamun ƙarin da ke cikin bus voltage da line voltage don abubuwan da suke musamman don in tabbatar da su za su cikin tsari)

• Line no-voltage & bus voltage present check

• Bus no-voltage & line voltage present check

• Both line and bus no-voltage check

• Non-check reclosing

2. Line No-Voltage Check da Synchronism Check Reclosing

Don kuɗi MN da aka nuna a wannan rubutu, terminal M ya yi "line no-voltage check" reclosing method, kuma terminal N ya yi "synchronism check" reclosing method.

Idan yadda ake samu shirye-shirye a cikin kuɗi MN da kuma ya yi karfin uku a duk faɗin, ya ƙara voltaji a cikin kuɗi. Saboda haka, terminal M ya ƙara cewa babu voltaji a cikin kuɗi, wanda ya jawo sharhi, kuma ya fitar da amfani da closing command bayan lokacin da ake yi time delay. Ba ni, terminal N ya ƙara voltaji a cikin bus da kuɗi; kuma farkon ƙarin da ke cikin abubuwan da suke musamman (tushen A) a cikin bus voltage da line voltage ya ƙara cikin tsari. Wannan yana nufin cewa synchronism conditions ya jawo sharhi, kuma terminal N ya fitar da amfani da closing command bayan lokacin da ake yi time delay.

Lura: Daga wannan yadda ake yi, ana iya ƙara cewa terminal da ya yi line no-voltage check ya yi karfin daidai. Saboda haka, ya kamata ya yi karfin a cikin kuɗi da ya fi shiga matsayin, kuma ya yi karfin daidai. Kafin ya yi haka, circuit breaker a cikin terminal ya kamata ya yi karfi shirye-shirye daidai a lokacin da yawa, wanda ya ba da yanayi da yawa. Terminal da ya yi synchronism check ba a yi karfin ba hata da a tabbatar da voltaji a cikin kuɗi da kuma synchronism conditions, kuma ya kamata ya yi karfin a cikin kuɗi da ya fi shiga, wanda ya ba da yanayi da yawa. Don in taimaka wajen balanci yanayi, ana iya yi swapping da line no-voltage check da synchronism check functions a duk faɗin.

Don in taimaka wajen yi karfin don in ƙara matsayin da ake yi "steal trip" (karfin da ba a yi daidai), ana iya yi synchronism check function a terminal da ya yi line no-voltage check; kafarsa, bayan "steal trip," ya kamata ya ƙara karfin saboda voltaji a cikin kuɗi. Ba ni a yi synchronism check function, ake iya yi karfin daidai don in ƙara synchronism check method.

Amma, a terminal da ya yi synchronism check, ba a iya yi line no-voltage check function ba. Idan ake yi haka, idan ake yi line no-voltage check a duk faɗin, za su iya yi karfin daidai bayan karfin a duk faɗin, wanda ya ba da yanayi da yawa.

• Non-check Reclosing Method Don kuɗi da ba a ka synchronism issues, ake iya yi non-check reclosing method bayan karfin uku. Misali, ake iya yi karfin a kuɗi da take da power supply daidai. Don wannan reclosing method, bayan ake fara, ake iya fitar da amfani da closing command bayan lokacin da ake yi time delay.

• Line No-Voltage & Bus Voltage Present and Other Methods 01 Line No-Voltage & Bus Voltage Present Check Wannan method ake iya yi a dual power source systems don faɗin da ya kamata ya yi karfin daidai.

Bus No-Voltage & Line Voltage Present Check Wannan method ake iya yi a receiving end side of single-ended power source systems, inda receiving end ya yi karfin bayan power supply side ya yi karfin daidai.

3.Both Line and Bus No-Voltage Check 

Wannan method ya kamata babu voltaji a cikin kuɗi da bus kabisa a yi karfin, kuma ake iya yi a single-ended power source systems inda receiving end ya kamata ya yi karfin daidai.

4.Combinations of the Above Three Methods

• Idan ake yi "Line No-Voltage & Bus Voltage Present" da "Both Line and Bus No-Voltage" checks a lokacin daidai, wannan zai ƙara line no-voltage check method. A wannan lokacin, ba a yi ma'anar da voltaji a cikin bus, amma kuɗi ya kamata babu voltaji don in jawo sharhi.

• Idan da aka amfani da "Bus No-Voltage & Line Voltage Present" da kuma "Both Line and Bus No-Voltage" a kan gaba-gaban, wannan zai zama hukumar da ba ake iya samun tsari na bus. A cikin halin, ba za mu fi kyau a tabbatar da yawan tsari na line ko abin da ita, amma bus ya kamata bai sami tsari don taimaka da hukumomi.

• Idan "Line No-Voltage & Bus Voltage Present," "Bus No-Voltage & Line Voltage Present," da kuma "Both Line and Bus No-Voltage" suna amfani da su a kan gaba-gaban, wannan zai zama hukumar da za a iya samun tsari na line ko bus. Hukumomin ya kamata a tabbatar da yadda line bai ba sami tsari, ko bus bai ba sami tsari, ko duk biyu bai ba su samu tsari. Wannan yanayi na nufin cewa shi ne da take a yi a cikin hukumar da ba ake iya samun tsari na line masu 220kV da sa zuwa.
