Hur man tillämpar kvoten för lågspänningskondensatorskåp

In the cost management of power construction projects, the application of quotas for low-voltage capacitor cabinets is an important part of the budget preparation. The rational selection of quotas directly affects the accuracy of project costs and the effectiveness of cost control. Due to the diverse types and complex configurations of capacitor cabinets, there are often many technical considerations in the actual application process. So, how Bör lågspänningskondensatorskåp tillämpas på kvoter?

1. Identifiering och positionering av utrustningstyper
Accurately identifying the type characteristics of capacitor cabinets is the first step in applying quotas. It is necessary to clearly distinguish different categories such as ordinary compensation cabinets, filtering compensation cabinets, and dynamic compensation devices, as the corresponding quota sub-items for each category vary significantly. The structural characteristics of the cabinets are also important criteria for differentiation, including the identification av installationsmetoder som fast typ och låstyp . Samtidigt är det nödvändigt att bekräfta om ytterligare funktionella moduler såsom intelligenta kontrollenheter och harmoniska undertryckningsenheter ingår . Dessa konfigurationsskillnader påverkar direkt valet av kvot-sub-items .}}

2. Principen om matchning av huvudparametrar
The electrical parameters of the capacitor cabinet are the core basis for applying the quotas. The rated voltage level determines the classification of the quota chapter, and it is necessary to strictly compare with the nominal voltage specified in the design documents. The total compensation capacity is another key parameter, which is usually applied in grades based on Kilo-Farads . Typen och specifikationen för huvudkretsomkopplaren måste också övervägas separat, till exempel kvoterna för skyddselement som brytare och säkringar måste beräknas separat .

3. Hänsynsfaktorer för installationsmetoder
The differences in installation methods will lead to variations in the quota for labor and materials. The materials and labor required for floor-mounted installation and wall-mounted installation are different, and corresponding quota items need to be selected. The construction methods of dense busbar connections and cable connections also need to be reflected in the quota application. For installation methods that require foundation construction, the costs Relaterat till grundarbetet måste beräknas separat .

4. System Felsökningsprojektavgifter
Systemfelsökning av kondensatorskåp är en oumbärlig del i kvotapplikationsprocessen . rutinmässiga elektriska test inkluderar grundläggande artiklar som isoleringstest och funktionell verifiering, som bör tillämpas enligt motsvarande kvoter . felsökning av intelligent kontrollenhet Separat . För enheter med harmoniska filtreringsfunktioner måste ytterligare speciella felsökningsobjekt som filtreringseffekttester läggas till .

5. Supporting Project Calculation Support
The complete quota application should include all related supporting work contents. Projects such as cable terminal head fabrication and busbar installation need to be calculated simultaneously. The installation and commissioning of the grounding system are usually listed separately and executed according to the corresponding quota. For projects that require the renovation of the original distribution system, the workloads of demolition and relocation should också inkluderas i budgeten .
