Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Of the present invention is the double breaking points moving contact structure of double power supply automatic transfer switch, and moving contact adopts a distinctive electric conductor, and the structure of two terminal contacts, during combined floodgate, two contacts contact simultaneously, and during separating brake, two contacts separate simultaneously.Only realized the separating brake feed motion of moving contact component by a rotating shaft, each action can only a deciliter power supply, misoperation will not be produced, effectively realize mechanical interlocked.
As shown in Figure 1, the double breaking points moving contact structure of a kind of double power supply automatic transfer switch, this structure specifically includes that movable contact 1, load stationary contact 1, load static contact 3, load stationary contact 24, insulating base 5, movable contact 26, moving contact 1, bearing pin 1, a-power supply stationary contact 9, a-power supply static contact 10, movable contact 3 11, moving contact spring 12, movable contact 4 13, B-source static contact 14, B-source stationary contact 15, bearing pin 2 16, moving contact 2 17, rotating shaft 18.This moving contact structure is provided with 2 moving contacts, it may be assumed that moving contact 1 and moving contact 2 17；Moving contact 1 and moving contact 2 17 are articulated with the opposite end of insulating base 5 respectively through bearing pin 1 and bearing pin 2 16, and insulating base 5 is sleeved in rotating shaft 18.Moving contact 1 can be freely rotatable around bearing pin 1；Moving contact 2 17 can be freely rotatable around bearing pin 2 16.Being additionally provided with moving contact spring 12 between moving contact 1 and moving contact 2 17, moving contact spring 12 is positioned at the relevant position of insulating base 5.Movable contact 26 and movable contact 3 11 respectively it is welded with at the two ends, left and right of moving contact 1；Movable contact 1 and movable contact 4 13 respectively it is welded with at the two ends, left and right of moving contact 2 17；Opposing sides at load static contact 3 is welded with load stationary contact 1 and load stationary contact 24；Described a-power supply static contact 10 end is welded with a-power supply stationary contact 9；Described B-source static contact 14 end is welded with B-source stationary contact 15.
