Abstract
The article considers the influence of the heating temperature of the contact sys-tem on the internal stresses in the bellows vacuum switch finite element method. Semi-Chen dependence of mechanical stresses in the material as a function of temperature during a given contact. Shown that the greatest mechanical load test the attachment of the bellows to the contacts and the vacuum chamber. Values of mechanical stress in emergency modes can exceed the yield strength in non-properly chosen material of the bellows.
