Uporaba in testiranje električnih IDC-kontaktov

Engelman, Luka (author), Benedičič, Janez (mentor)

Diplomsko delo je nastalo na podlagi literature o električnih kontaktih in tehnologije delovanja električnih izolacijsko-premičnih kontaktov (IDC). V njem so predstavljeni princip delovanja IDC-kontaktov, njihove prednosti in omejitve. V eksperimentalnem delu diplomskega dela je prikazano, ali pri določenih temperaturnih testih pride do bistvene spremembe električne upornosti v stiku kontaktov in vodnika ali ne. Vzorčni kosi so bili izdelani za dve obstoječi aplikaciji, in sicer za aplikacijo električne vodne črpalke za hlajenje električnih baterij ali pogonskega motorja v električnih in hibridnih avtomobilih in za aplikacijo električne oljne črpalke za mazanje in hlajenje avtomatskih menjalnikov. Na vzorčnih kosih so bile pred začetkom izvajanja testov izvedene meritve električne upornosti in nato enako še po vsakem izvedenem testu. Na podlagi meritev se je potrdila oziroma ovrgla zanesljivost električnih IDC-kontaktov. Prav tako je v eksperimentalnem delu predstavljena stroškovna primerjava pri prehodu z uporabe običajnih električnih kontaktov na IDC-kontakte.

Abstract

The thesis is based on literature on electircal contacts and the technology of electrical IDC contacts. It presents the prinicples of insulation displacement contacts (IDC), their advantages and limitations. In the experimental part of thesis it is shown if after certain temeprature tests comes to a significant change in the electrical resistance between the conductor and the contact, or not. The sample pieces were designed for two existing applications of a electrical water pump for cooling drive motor or electric batteries in electrical and hybrid vehicles and on an application of electric oil pump for lubrication and cooling of automatic gearboxes. Electrical resistance measurement were performed on the sample pieces before the start of the tests, and then the same after each test was finished. Based on the measurements, the reliability of the IDC-contacts was confirmed or refuted. The experimental also presents a cost comparison in the transition from the use of conventional eletrical contacts to IDC-contacts.
