Meanwhile, the working principle is disclosed in the specification: the three-section type double-power-supply change-over switch works as follows: in the double-opening state, when a first excitation switch acts, a first driving plate is pushed to rotate forward by a first deflector rod, a first gear and a second gear rotate along with the first gear, the first gear drives a first poking pin to act only through a third arc-shaped groove in the reverse rotation of a first rotating plate at the initial stage of rotation, so that a first swing arm swings reversely, a first energy storage spring carries out energy storage action, at the moment, the first driving plate does not act due to the existence of a fourth arc-shaped groove, after the first swing arm passes through the inflection point of the first energy storage spring, the first energy storage spring rapidly releases energy, the first swing arm swings forward rapidly to drive the first driving plate and a first rotating shaft to reversely rotate, a first moving contact and a first fixed contact are closed, normal electric switching-on is realized, and when the first swing arm swings forward rapidly, the first swing plate does not reversely rotate any more due to the existence of the third arc-shaped groove, and an intermediate gear and the driving plate also stay in place; in addition, in the common electric closing action process, although the second gear can drive the second rotary table to reversely rotate, the fifth arc-shaped groove of the second rotary table does not generate a swinging action of the second swing arm due to the reverse rotation of the second rotary table, the second energy storage spring does not generate an energy storage action, the second driving disc and the second rotating shaft do not generate actions, and the corresponding second moving contact does not generate actions; when the normal electric brake is required to be switched off, the second excitation switch acts to push the third deflector rod to enable the driving plate to reversely rotate and return, and the switch returns to the double brake-off state again. If the standby electric switching-on is needed, the second excitation switch firstly acts, the second deflector rod drives the driving plate to reversely rotate at the first time, the first gear and the second gear rotate along with the driving plate, the second gear drives the second poking pin to act only through the fifth arc-shaped groove at the initial rotation stage of the second gear, the second swing arm swings forwards, the second energy storage spring carries out energy storage action, at the moment, the second driving plate does not act due to the existence of the sixth arc-shaped groove, after the second swing arm passes through the inflection point of the second energy storage spring, the second energy storage spring rapidly releases energy, the second swing arm rapidly swings forwards to drive the second driving plate and the second driving shaft to positively rotate, the second movable contact and the second fixed contact are closed, standby electric switching-on is realized, and when the second swing arm rapidly swings forwards, the second swing plate does not rotate forwards any more due to the existence of the fifth arc-shaped groove, and the middle gear and the driving plate also stay in place; in addition, in the process of the standby electric switching-on action, the first gear drives the first rotary table to reversely rotate, but because the third arc-shaped groove of the first rotary table makes a yielding action, the reverse rotation of the first rotary table does not enable the first swing arm to generate a swinging action, the first energy storage spring does not perform an energy storage action, the first drive and the first rotary shaft do not generate actions, and the corresponding first moving contact does not generate actions; when the standby power switch is needed, the first excitation switch acts to push the fourth deflector rod to enable the driving plate to rotate forward to return, and the switch returns to the double switch-off state again. The exciting switch comprises an exciting coil (not shown in the figure) and a movable iron core, the exciting coil is wound on a coil framework, the movable iron core moves in a hollow mode along the coil framework, the two movable iron cores are connected with a poking plate 7, the poking plate moves to drive the first poking rod or the second poking rod to move, and two return springs are arranged at the tail end of the movable iron core and used for returning. The structure can enable the exciting coil to generate a magnetic field after being electrified so as to be used for adsorbing the movable iron core to move along the hollow straight line of the framework, and further drive the first deflector rod or the second deflector rod to move.
The following defects exist in the structure: 1. the excitation switch is unstable in output, and the main reason is that the connection structure of the movable iron core and the poking piece is not reliable enough, so that the poking piece is loose, and the output stroke is influenced; 2. the transmission is unreliable, and in the process of driving the first rotary table and the second rotary table, the movable iron core is generally rotated by a certain angle (about 60 degrees) due to the stroke, and when the energy storage spring is driven to be compressed and then passes through a temporary point state, the situation of blocking stagnation exists, so that the energy storage spring can not be compressed and then smoothly passes through the temporary point to release energy, and the switching failure is caused.
