Abstract

The aim of this thesis is the design of high voltage disconnectors. In the introduction I will give general characteristics and use of defeat. Next, bring the theoretical analysis of the proposed components of the disconnector. In the proposal itself through the design of insulation, and Busbars isolators. Perform the calculation of electrodynamic forces and calculation of steady warming by jednořadového thermal field. In the proposed isolator then perform a calculation on a short-term warming smallest cross-section disconnector. Furthermore, through the design of the pressure spring for contacts. Contact resistance during the passage of a specified short-circuit current calculation then I check my voltage drops on these contacts. The thesis is recommended torque on the shaft. Mass moment of conclusion of the work performed on the simplified model, the weight of the mechanical parts, designed to switch disconnectors from one state to another.
