Abstract

The invention relates to the field of low-voltage electrical appliances, and in particular to a three-segment automatic transfer switch. The switch comprises an energy storage operation mechanism anda moving contact device, wherein the energy storage mechanism comprises a first energy storage component, a second energy storage component, a driving gear and a rotary disk device; the first energy storage component and the second energy storage component are respectively connected with the rotary disk device; the first energy storage component and the second energy storage component are respectively in driving connection with the driving gear; and the driving gear is in driving connection with the moving contact device. The three-segment automatic transfer switch disclosed by the invention has the beneficial effects that the automatic transfer switch can rapidly transfer between a double power-off state and a first power-on state and between the double power-off state and a second power-on state through the energy storage mechanism, thereby significantly improving the power-on / power-off capability of the automatic transfer switch.

Description

Technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a three-stage automatic transfer switch. Background technique [0002] At present, automatic transfer switches are used for power supply in many important occasions. Automatic transfer switches are switching appliances that automatically switch the load circuit from one power supply to another circuit. Therefore, there are very important requirements for the continuity and reliability of power supply. Product reliability is particularly important in emergency power supply systems. For the existing three-stage automatic transfer switching appliances, the opening and closing speed of most products depends entirely on the switching speed of the drive motor. The switching speed of such products is difficult to achieve the purpose of fast opening and closing, resulting in the making and breaking capacity not tall. Summary of the invention [0003] The purpose of the presen...
