The invention discloses a dual-power automatic change-over switch, which comprises a drawing frame, a main change-over switch and a bypass change-over switch; the main change-over switch can be shakenin and out of the drawing frame, a first busbar is arranged on the main change-over switch, a second busbar is arranged on the bypass change-over switch, the first busbar and the second busbar are connected through a bridge-type contact, and the bridge-type contact comprises a pair of contact mounting frames, a limiting baffle arranged between the pair of contact mounting frames, an upper contactunit and a lower contact unit; and one end of the first busbar is inserted between the upper contact unit and the lower contact unit, the upper contact unit and the lower contact unit are respectively connected between the pair of contact installation frames through shaft pins, an elastic device is arranged between the upper contact unit and the lower contact unit, and the upper contact unit andthe lower contact unit respectively abut against the upper side and the lower side of the limiting baffle through the elastic device. The dual-power automatic change-over switch is reasonable in structure, facilitates saving of product materials, and facilitates improvement of reliability of electric connection.
Description
technical field [0001] The invention relates to a double power supply automatic transfer switch. Background technique [0002] With the development of society, people's requirements for the power grid and its transmission and distribution process are gradually increasing, mainly reflected in the safety, reliability, continuity, and easy maintenance of power supply equipment. Therefore, the above-mentioned The typical automatic transfer switch is widely used in high-rise buildings, communities, hospitals, airports, docks, fire protection, metallurgy, chemical industry, textiles and other important places where power failure is not allowed. The main function of the automatic transfer switch is that when the normal power supply has problems or failures, it automatically converts the transmission and distribution line from the main power supply to the backup power supply, so as to realize the uninterrupted power supply of the entire circuit and ensure the continuous power consum...
