  1. 1. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Hanna Damsgaard Falck; [2023]
    Nyckelord :Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

    Sammanfattning : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. LÄS MER

  3. 2. Air and Silicon resistivity design space for dielectric simulations

    Kandidat-uppsats,

    Författare :Oscar Hammarberg; Anton Larsson; Adam Steiner; [2022]
    Nyckelord :electrical bushings; simulations; humidity; electrical breakdown; corona discharge; comsol multiphysics;

    Sammanfattning : Electrical bushings are a type of hollow or solid conductor withinsulation designed to allow a conductor to pass through a conductingbarrier without making electrical contact and are very important forsafe transportation of electricity. The bushings vary in size, but allbushings have a solid or hollow conductor. LÄS MER

  4. 3. Epoxy filling simulation of an RIP bushing

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Nil Tabudlong Jonasson; Simon Palm; [2022]
    Nyckelord :COMSOL; Porous Media Flow; RIP Bushing; Electrical Bushing; Filling Simulation;

    Sammanfattning : The manufacturing process for the core of an RIP bushing was studied. Simulations of a test model was performed, due to the non-linear nature of the fluid filling process. Varying of governing parameters in the model, that could realistically be varied, was carried out and their affect was observed. LÄS MER

  5. 4. Design and evaluation of a shock load resistant dynamic chain plate

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Olsson; [2022]
    Nyckelord :Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Sammanfattning : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. LÄS MER

  7. 5. Early Anomaly Detection in Electrical Bushings Manufacturing at Hitachi Energy

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felipe Quintero Suárez; [2022]
    Nyckelord :Machine Learning; anomaly detection; manufacturing process.; Maskininlärning; avvikelsedetektering; tillverkningsprocess.;

    Sammanfattning : The manufacturing of electrical bushings for high voltages is complicated and highly demanding technology-wise. This process has more than 10 steps where a single mistake in the chain could cause a complete failure of the final product. A faulty bushing represents high costs to the company both economically and in terms of public image. LÄS MER
