Maisuguna da Maimaita
Maisuguna da maimaita (CBs) suna gina wajen kawo da rufe hanyar jiki daban-daban har zuwa adadin mai yawa a kan. Wannan ya kunshi hanyoyi da hanyoyin mai yawa. Maisuguna da maimaita da aka saka a cikin masana'antar sakamakon suna bukatar wadanda suke yi nasarar da ba nasarar da gwargwadon mai zama.
Maisuguna da Maimaita na Hanyoyi
Maisuguna da maimaita na hanyoyi (LBS) suna iya maye hanyoyi a tushen kayayyakin da ba saukinsu, amma babu iya maye hanyoyin mai yawa. Su ne daidai don inganta hanyoyi na musamman, bali ba a fuskantar abubuwan da ke faru ba.
Maisuguna da Maimaita na Tsara
Maisuguna da maimaita na tsara (DSs) suna iya maye hanyoyi a tushen da ba da hanyoyi. Suna amfani da su don maye hanyoyi daga busbars da ba da hanyoyi da hanyoyi na ma'aici da adadin mai yawa. Yana bukata mu'amala da maisuguna da maimaita (CBs) don hana shiga rayuwar da damar daidai.
Maisuguna da Maimaita na Tsarki
Maisuguna da maimaita na tsarki (ESs) suna amfani da su don tsarkar zafi. Ana iya haɗa ESs da DSs don alamar cin bayanai.
Fuses
Fuses suna daidai da za a saka a cikin masana'antar low voltage (LV) da medium voltage (MV). Suna kusa hanyoyi ta hanyar magance mai yawa da kuma zan iya kawo da su ba danganta. A cikin masana'antar LV, fuses suna haɗa da maisuguna da maimaita na tsara (DSs).
Ingancin Kayayyaki na HV Switchgear
A nan ana bayyana biyu na kayayyaki na HV switchgear feeders, kamar yadda aka nuna a diagram:
(a) Overhead Line Feeder with Double Busbar
Busbar DS: Maisuguna da maimaita na tsara da aka saka a kan busbar.
CB: Maisuguna da maimaita wanda ya iya maye hanyoyi da hanyoyin mai yawa.
Feeder DS: Maisuguna da maimaita na tsara da aka saka a kan kayayyakin feeder line.
ES: Maisuguna da maimaita na tsarki don tsarkar zafi.
CT: Current transformer don ƙirƙira hanyoyi.
VT: Voltage transformer don ƙirƙira voltage.
CVT: Capacitive voltage transformer don ƙirƙiran daɗi.
Blocking Reactor: An amfani da ita don kusa hanyoyin mai yawa ko kuma bayyana reactive power compensation.
(b) Transformer Feeder with Double Busbar
Busbar DS: Maisuguna da maimaita na tsara da aka saka a kan busbar.
CB: Maisuguna da maimaita wanda ya iya maye hanyoyi da hanyoyin mai yawa.
Feeder DS: Maisuguna da maimaita na tsara da aka saka a kan kayayyakin transformer feeder.
ES: Maisuguna da maimaita na tsarki don tsarkar zafi.
CT: Current transformer don ƙirƙira hanyoyi.
VT: Voltage transformer don ƙirƙira voltage.
CVT: Capacitive voltage transformer don ƙirƙiran daɗi.
Blocking Reactor: An amfani da ita don kusa hanyoyin mai yawa ko kuma bayyana reactive power compensation.
Bayanin Diagram
Diagrams sun nuna biyu na kayayyaki:
Overhead Line Feeder with Double Busbar: Ingancin wannan ya ba da ilimi don maye waɗannan lines da kuma bayyana redundancy a kan double busbar system.
Transformer Feeder with Double Busbar: Ingancin wannan ya tabbatakar da hana shiga rayuwar da inganta transformers ta hanyar bayyana redundant path a kan double busbar system.
Duka dukkan ingancin suka ƙunshi abubuwan da suka fiye kamar maisuguna da maimaita, maisuguna da maimaita na tsara, maisuguna da maimaita na tsarki, current transformers, voltage transformers, capacitive voltage transformers, da blocking reactors don hana shiga rayuwar da idan daidai na HV switchgear.
