ELECTRICAL TRANSFER SWITCH SYSTEM

摘要

A system including an automatic transfer switch configured to selectively route power from a first power source or a second power source to a load, comprising a switch configured to be moved between a first position and a second position, a first set of electrical contacts configured to route the power from the first power source when the switch is in the first position, a second set of electrical contacts configured to route the power from the second power source when the switch is in the second position, and a first arc chute housing configured to substantially enclose the first set of electrical contacts when the switch is in the first position.

1. A system, comprising:
an automatic transfer switch configured to selectively route power from a first power source or a second power source to a load, comprising:
a switch moveable between first and second positions and configured to rotate a shaft;a first stationary electrical contact; anda first contact support assembly, comprising:
a first contact support coupled to a first moveable electrical contact, wherein the first moveable electrical contact is configured to couple to the first stationary electrical contact when the switch is in the first position to route power from the first power source to the load;a first pin extending through an aperture of the first contact support; anda first link bar coupled to the shaft and the first pin and configured to enable rotational movement of the first contact support about an axis of rotation parallel to the shaft to selectively couple or decouple the first moveable electrical contact from the first stationary electrical contact.
