Embodiment Construction

[0049] The following describes specific embodiments of a rotary driver for a dual power supply switch according to the present invention with reference to the accompanying drawings. In the various drawings, the same or corresponding elements are provided with the same reference signs. For the sake of clarity, the drawings only show the main components, and those skilled in the art can easily imagine conventional structures and arrangements not shown. Hereinafter, terms such as "first", "second", "a", "another" and so on are only used to distinguish similar elements, and these terms and other similar terms do not limit the scope of the present invention.

[0050] figure 1 A rotary drive 1 according to the invention is shown. The rotary drive 1 comprises a rotor 1 and a stator 2 . The rotor 1 can be a strip-shaped permanent magnet, which has a first rotor magnetic pole (such as N pole) 11 and a second rotor magnetic pole (such as S pole) 12 oppositely arranged along its lengt...

Abstract

The invention provides a rotary driver for a dual power supply switch, the dual power supply switch has a moving contact electrically connected to a load circuit, a first static contact electrically connected to a first power supply, and a first stationary contact electrically connected to a second power supply. The second static contact of the second power supply. The rotor of the rotary drive has rotor poles, and the rotor is linked with the movable contact and can rotate between a first direction and a second direction. The stator of the rotary drive includes four iron core parts and coils, the first iron core part and the third iron core part are arranged oppositely, the second iron core part and the fourth iron core part are arranged oppositely, and the coil is arranged on the first iron core along one direction. part and the adjacent second core part, and wound on the third core part and the adjacent fourth core part in the opposite direction. When there is no current in the coil, the moving contact remains in electrical contact with the first static contact or the second static contact; One of the fixed contacts turns to the other.

Description

technical field [0001] The invention relates to a rotary driver for a dual power supply automatic transfer switch, and a dual power supply automatic transfer switch including the rotary driver. Background technique [0002] Dual power automatic transfer switch (ATSE) is widely used in emergency power supply system. ATSE can automatically or manually switch the load circuit from one power source to another based on the condition of the power circuit, such as switching between mains and backup power, so as to maintain continuous and reliable operation of the load circuit. The driver is an important component of the ATSE, which is used to drive the moving contact electrically connected to the load to switch between the static contacts respectively connected to the two power sources. [0003] Some existing technologies use a motor as the power source of the ATSE driver, which requires a gear box to change speed to obtain the torque required for the switching action, which makes...
