→6.4.2 Contact Physics – Formulas
als bild?
*'''Contact resistance''' <br />RK = Re + Rf
*'''Dynamic contact separation''' (without considering magnetic fields caused by the current path) <br />FA 0,8 x I²(Rule of thumb with F in N and I in kA)
*'''Contact voltage and max. contact temperature''' <br />T kmax 3200 UK
*'''Contact resistance at higher contact forces (according to Babikow)'''<br />R = cF -m K K
For F between 10 and 200 N K
c = material dependent proportionality factor
