Introducere functionum principalium

1. Automationem feeder localiter：

1) Adaptiva typus comprehensivus, Automatio adaptiva comprehensiva feeder obtinetur per methodum "apertura per amissionem tensionis, clausura per moram potentiae", combinata cum technologia deprehensionis circuitus brevis/faulti terre et strategia controlis prioritatis processus viae faulti, coniuncta cum secunda clausura switch outgoing substationis, ad obtinendum localizationem et isolationem adaptationem structurarum distributionis multibrancharum et multiconnexarum.   Prima clausura isolat sectionem faulti, et secunda clausura restituit supplymentum potentiae sectionibus non faultis.

2) Typus temporis tensionis, Automatio "typus temporis tensionis" feeder obtinetur per combinationem characterum operativorum switch "apertura sine tensione, clausura per moram potentiae" cum secunda clausura switch outgoing substationis.  Prima clausura isolat sectionem faulti, et secunda clausura restituit supplymentum potentiae sectioni non faultae.  

3) Typus temporis tensionis currentis, Typus temporis tensionis currentis addit discriminationem pro currente faulti et currente terre super basis typi temporis tensionis, sequens logicam basicam clausurae intra X tempus limitatum potentiae, detectio residuae tensionis lockout intra Y tempus limitatum, amissio tensionis intra Y tempus limitatum post clausuram, et detectio currentis faulti lockout et apertura.   Simul, habet logicam lockout et apertura sine detectione currentis faulti intra Y tempus limitatum post clausuram, ita celerans processum isolationis faulti. Si switch adoptat mechanismum spring-operated, potest celeriter isolari ab faultis instantaneis per additionem apertionis per moram amissionis potentiae (coniuncta cum celeri reclosure tempore switch outgoing substationis).

Q: Quid est recloser?

A: Dispositivum reclosing est dispositivum quod automaticam deprehensionem currentis faulti et automaticam disjunctionem circuitus quando faultus occurrat, et deinde operationes reclosing multiplices perficere potest.

Q: Qualis est functio recloser?

A: Principaliter in rete distributionis utitur. Quando faultus temporarius in linea (sicut rami contactus lineae pro tempore brevi) occurrit, dispositivum reclosing per operationem reclosing supplymentum potentiae restituere potest, quod magnopere tempus et ambitum outage minuit et fiduciam supplymenti potentiae augit.

Q: Quomodo recloser determinat typum faulti?

A: Monitorat characteres sicut magnitudinem et durationem currentis faulti. Si faultus est permanentis, post numerum reclosing praeordinatum, dispositivum reclosing lockabitur ut ulterius damnum dispositivo vitetur.

Q: Quae sunt scenarii applicationis reclosers?

A: Largiter in rete distributionis urbana et rura utilisatur, quod varia possibilia faulta lineae efficaciter obviam ire et stabile supplymentum potentiae assecurare potest.
