Abstract
The invention provides a simple intelligent dual-power transfer switch driven by a cylindrical single-phase linear asynchronous motor with less mechanical contact during driven movement, which consists of a cylindrical single-phase linear asynchronous motor primary electrode, a rod-like secondary electrode, a contact mechanism and an operation handle. By using the characteristic that a linear motor can do linear motion at high speed and taking a high-performance cylindrical single-phase linear asynchronous motor as power to drive the contact mechanism of the dual-power transfer switch, selective switching and instant switching of a power supply can be realized.
