Abstract

This invention relates to a three-position manual operation unit of an automatic conversion switch appliance, in which, said manual operation unit is connected with the shaft of right and left switches connecting to a double-touch head system, said manual operation unit includes an installing board, a cam, a handle connected with the cam, which is connected with the installing board rotationally, said cam is connected with the drive units of the right and left connection rods, the driving unit of the left is connected with the left switch shaft and that of the right one is connected with the right switch shaft, the handle drives the cam to rotate to turn on supply 1 and 2 separately and cut them at the same time and prevent them from being turned on at the same time.

Description

(1) Technical field [0001] The invention relates to a three-position manual operation mechanism of an automatic transfer switch electric appliance. (2) Background technology [0002] In the prior art, automatic transfer switch appliances are classified according to their structure: combined automatic transfer switch appliances assembled by two circuit breakers, which have large volume, slow switching speed, and low performance indicators; the other type is specially designed for power supply The integrated automatic transfer switching electrical appliance designed for switching is characterized by small size, fast switching speed, reliable action, and high performance indicators. The one-piece structure only has products below 400A in the current market. [0003] The double-contact system of the automatic transfer switch electrical appliance includes a moving contact that is in contact with or disconnected from the power supply. The moving contact is connected to the switch...
