Isicelo semitha yamanje kanye ne-Frequency Meter e-Iceland Wooden Factory

Abstract: Ubuhlakani, ukucolisiswa kanye nokubonwa kwesistimu yokusabalalisa kuwumkhuba wokuphathwa kokusabalalisa. Imitha yamandla ehlakaniphile yakhelwe futhi yafakelwa isekethe yokusabalalisa amandla, ukuze kuqashwe isikhathi sangempela isimo sokusebenza sesekhethi yomthwalo ngamunye ngokubeka imingcele yemitha ehlakaniphile. Ingathuthukisa ukuphepha kokusetshenziswa kwamandla, ithuthukise ukusebenza kahle kokulungiswa kwemishini, inciphise izindleko zabasebenzi zokuyilungisa, futhi ibone ukugadwa okunganakiwe kohlelo lokusabalalisa. Ngokuqoqwa kwedatha, ukuqapha ngesikhathi sangempela amapharamitha kagesi, ukuhlaziywa kwekhwalithi yamandla kanye nesistimu yokusabalalisa esebenzayo, kuzokonga izindleko zabasebenzisi zokulondoloza amandla. Lesi sihloko sinikeza isingeniso esifushane se-ammeter ye-Acrel PZ kanye nemitha yefrikhwensi esetshenziswa kuphrojekthi yokuqapha izimoto yenkampani yase-Iceland Tandraberg ehf.

1. Uhlolojikelele lwephrojekthi

Inkampani ye-Tandraberg ehf, etholakala e-Eskifjörður, ingomunye wabakhiqizi abakhulu bamaphalethi aqandisiwe e-Iceland, Ugesi wayo oyinhloko wokukhiqiza ungumthwalo wezimoto, osetshenziselwa ukusika inqubo. Njengoba ikhabethe lokuqala lokulawula injini lingafaki ithuluzi lokulinganisa amandla, futhi isimo sokusebenza se-Variable-frequency Drive kanye ne-moter asaziwa. Ngakho-ke, bathenge uchungechunge lwe-Acrel PZ olunezigaba ezintathu ze-ammeter yokuqapha imoto yamanje kanye nemitha yefrikhwensi yokuqapha ushintsho lwemvamisa.

2.PZ Series Programmable Intelligent Electric Meters

Uchungechunge lwamamitha lwe-PZ lusebenzisa ubuchwepheshe bokusampula be-AC, obungakwazi ukukala ngokuhlukana okwamanje, i-voltage, amandla, isici samandla kanye nemingcele yamandla kagesi kugridi. Ingasetha ipharamitha kagesi ngokusebenzisa inkinobho yephaneli.Le mitha ine-interface yokuxhumana ye-RS-485, yamukela iphrothokholi ye-Modbus; futhi ingaguqula isignali yamandla ibe isignali ye-analog ejwayelekile ye-DC. Imitha iphinde ibe nokufaka kokushintshayo/okuphumayo, okuphumayo kwe-relay/alarm, njll.

5.Isiphetho

Imitha yamandla yochungechunge lwe-PZ inokusebenza kwentengo ephezulu, engangena esikhundleni sesidlulisi samandla nezinye izinsimbi zokulinganisa. Njengedivayisi ethuthukisiwe yokutholwa ehlakaniphile nedijithali, imitha yamandla isetshenziswe kabanzi ezinhlelweni ezihlukahlukene zokulawula, izinhlelo ze-SCADA kanye nezinhlelo zokuphatha amandla.
