Abstract

The invention relates to a double-power-source automatic change-over switch comprising a controller, a change-over device, a contact system, and micro switches. The change-over device comprises a mechanism frame, a motor, a gear reversing assembly, and a change-over assembly. The change-over assembly comprises a transmission disc and two transmission arms. The two transmission arms are each equipped with an energy storage mechanism. A first transmission component and a second transmission component are respectively fixed to the upper end faces of the two transmission arms. The upper ends of the first transmission component and the second transmission component are correspondingly installed on a first moving contact support and a second moving contact support of the contact system. The two transmission arms are respectively arranged at the two sides of the transmission disc. The transmission disc includes two rotating plates and two shifting rods. The two transmission arms are each provided with clamping grooves corresponding to the shifting rods. The shifting rods can slide in the corresponding clamping grooves when rotating along with the transmission disc, and the two shifting rods can drive the corresponding transmission arms to rotate. The double-power-source automatic change-over switch of the invention has the advantages of small size, strong breaking capacity, and stable and reliable performance.

Description

technical field [0001] The invention specifically relates to a double power supply automatic transfer switch. Background technique [0002] At present, many industries and departments have very high requirements on the reliability of power supply. In order to ensure the continuity of power supply, many important occasions have adopted dual power automatic transfer switches to power electrical appliances. As an essential device for power switching, its main function is that when the normal power supply fails, it can automatically switch to the backup power supply to continue supplying power to the load, and it can automatically perform reverse switching after the power supply returns to normal, so as to meet the requirements of the low-voltage power supply system for power supply switching. requirements. The structural design of the existing dual power automatic transfer switch is unreasonable, so the dual power automatic transfer switch has the defects of unstable performan...
