Abstract:
The present application relates to the technical field of electric switches. Disclosed are a switch unit, an isolating switch and a power supply system. The switch unit comprises a shell, a moving contact arranged in the shell, a moving contact support, a fixed contact, and an arc extinguishing chamber corresponding to the fixed contact, wherein the moving contact can be connected to the fixed contact in an inserted manner; an electric arc guide surface is formed on the fixed contact; the fixed contact is connected to an arc introduction sheet; the electric arc guide surface is connected to one side surface of the arc introduction sheet to form an arc introduction surface; and the arc introduction surface extends to one side of the arc extinguishing chamber, so that an electric arc generated at the fixed contact is introduced into the arc extinguishing chamber by means of the arc introduction surface. The arc introduction effect can be improved, thereby improving the arc extinguishing capability of the isolating switch.
