Abstract

The invention relates to the technical field of switch equipment and discloses a conversion switch. The conversion switch comprises a controller, a driving device, a transmission mechanism, a switch moving contact system, a commonly-used static contact system and a standby static contact system, wherein the controller is electrically connected with the driving device, the transmission mechanism comprises an active shaft, and a commonly-used active gear and a standby active gear connected in series with the active shaft, a commonly-used driven gear, a standby driven gear, a commonly-used tooth bar assembly and a standby tooth bar assembly, and the active shaft is driven by the driving device to rotate. The conversion switch has advantages of high transmission efficiency, simple structure, reliable transmission and small integral size.

Description

technical field [0001] The invention relates to the technical field of switchgear, in particular to a transfer switch. Background technique [0002] In low-voltage electrical products such as dual-power automatic transfer switches, load switches, isolating switches, and contactors, the action of the transmission mechanism is required to realize on-off or conversion. For example: dual power supply automatic transfer switch is used to realize the power conversion between the common power supply and the backup power supply, and ensure the safety of key users' electricity use. The automatic transfer switch is composed of transmission mechanism, arc extinguishing system and other components. When the main power supply fails, the automatic transfer switch can automatically detect the power failure and automatically transfer to the backup power supply. The transmission mechanism is adopted in the existing automatic transfer switch to realize the function of changing the position ...
