Abstract

A three-position manual operating mechanism for an automatic transfer switch. The manual operating mechanism is connected to the left and right switch shafts. The left and right switch shafts are connected to a double contact system. The manual operating mechanism includes a mounting plate, a cam, handle, the handle is connected to the cam, the cam is rotatably connected to the mounting plate, the cam is connected to the left link transmission mechanism and the right link transmission mechanism, and the left link transmission mechanism is connected to the left switch The rotating shaft, the right connecting rod transmission mechanism is connected with the right switch rotating shaft. Driven by the handle to rotate the cam, the power supply I and the power supply II can be switched on separately, and the power supply I and the power supply II can be turned off at the same time, and can prevent the power supply I and the power supply II from being turned on at the same time. The invention provides a three-position manual operating mechanism for an automatic transfer switch appliance with simple structure, fast switching speed and high performance index.

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...
