The invention discloses a dual power supply opening and closing drive conversion device, which comprises a housing, and a switching slider slidingly installed in the housing. The switching slider is equipped with moving contact electrodes, and the housing is respectively located on the moving contact electrode Static contact electrodes are installed at both ends, and a buffer energy storage mechanism is installed at both ends of the housing. The buffer energy storage mechanism includes a buffer assembly and an energy storage assembly, and the housing is installed with a Switch the relay drive mechanism for further advancement of the slider. Buffering the switching slider through the buffer component is beneficial to prolong the service life of the device, and when switching the power supply, the energy storage component unlocks the switching slider, and the buffer component assists the switching slider to improve the switching slider for power supply. The speed of the switching action is reduced, and the switching slider in motion is further pushed through the relay drive mechanism to complete the switching of the power supply, which is beneficial to shorten the switching time of the power supply.
Description
technical field [0001] The invention relates to the technical field of power supply changeover switches, in particular to a dual power supply opening and closing drive conversion device. Background technique [0002] The dual power transfer switch is used in the power supply system. When the common power supply fails, it can not only prevent the faulty power supply from supplying power to the load, but also reliably select a qualified power supply for normal operation to ensure uninterrupted power supply. Therefore, dual power transfer switches are widely used and suitable for different occasions, such as hospitals, airports, docks, etc., all rely on dual power transfer switches to provide continuous power supply. At present, the dual power transfer switch is divided into electronic type and mechanical type. The electronic type dual power transfer switch can complete the power switching within one power frequency cycle, but its structure is precise, not only high in cost but...
