Yadda Ake Karkashin Kirkiyar Haɗin Isolator Duk Da Zama

Koɗar da kontrol ta hanyar disconnector (isolator) da circuit breaker da yake shiga yana iya zama na gaskiya wajen kare magana masu lafiya bayan disconnector a lokacin da aka fi sako. Amma, a lokutan da ake yi da disconnector na bus-side da line-side, ya kamata a yi abin da ba tushen daidai, wanda ba a tabbas ba ake amfani da shi a cikin principles na switching, kuma wanda ke jin daidai a cikin hadisan a system ta noma.

 Don in kare wasu abin da ba tushen daidai, a kan substation da power plants da ba suka amfani da coded mechanical interlock (program lock) anti-misoperation systems, ya kamata a yi nasara a cikin wiring na disconnector da yake shiga don in kare abin da ba tushen daidai, kuma in kare mafi yawan hadisan da ba da kyau.

1.Siffar na Disconnector Control da Interlocking Circuit
Auxiliary contacts na disconnectors suna da shiga a circuits daban-daban: specifically, normally closed (NC) auxiliary contact na line-side disconnector an samun shi a series da control circuit na bus-side disconnector, amma normally open (NO) auxiliary contact na bus-side disconnector an samun shi a series da control circuit na line-side disconnector.

2.Disconnector Interlocking Wiring Ta Electromagnetic Locks (Anti-Misoperation)

Wiring na yanzu ya kare magana masu lafiya a cikin operations na disconnector, kuma ya kare amfani da sequence na established switching, don in kare violations na operational procedures.

• A lokacin da ake rufe current: Ba a duba circuit breaker, ya kamata a duba line-side disconnector kafin a duba bus-side disconnector.

• A lokacin da ake sake rufe current: Idan circuit breaker yana cikin wuya, ya kamata a sake rufe bus-side disconnector kafin a sake rufe line-side disconnector.

3.Koyar na Wiring Scheme Na Yanzu

• Wiring na yanzu ya da dalilai masu original na disconnector control circuit, kuma ya kare amfani da rules na switching sequence, wanda ke tsarki in kare mafi yawan abin da ba tushen daidai da accidents.
  

• Design na yanzu yana da kyau, mai inganci, kuma bai da wurin. Ya yiwuwa a cikin electromagnetic anti-misoperation locks, da kuma a cikin pneumatic, electric, ko electro-hydraulic operating mechanisms.

• A kan installations da ba suka amfani da coded program-lock anti-misoperation systems, wiring na yanzu ya kare "soft" program lock, wanda ke tsarki in kare amfani da procedural enforcement through electrical interlocking.
