Meanwhile, the working principle is disclosed in the specification: the three-section dual-power change-over switch works as follows: under the state of double-brake, when the first excitation switch acts, the driving plate is pushed to rotate forward through the first driving lever at the first time, the first gear and the second gear rotate along with the first excitation switch, the first rotating disc rotates reversely only through the third arc-shaped groove to drive the first driving pin to act at the initial rotation stage of the first gear, so that the first swing arm swings reversely, the first energy storage spring performs energy storage action, at the moment, the first driving plate does not act due to the existence of the fourth arc-shaped groove, when the first swing arm rapidly swings forwards, the first energy storage spring rapidly releases energy, the first swing arm rapidly swings forwards to drive the first driving disc and the first rotating shaft to reversely rotate, so that the first moving contact and the first static contact are closed to realize common electric switching-on, and when the first swing arm rapidly swings forwards, due to the existence of the third arc-shaped groove, therefore, the first rotary disc does not rotate reversely any more, and the intermediate gear and the drive plate can stay at the original positions and cannot move; in addition, in the process of the common electric switching-on action, although the second gear can drive the second turntable to reversely rotate, the fifth arc-shaped groove of the second turntable does a abdicating action, so that the second swing arm cannot swing due to the reverse rotation of the second turntable, the second energy storage spring cannot perform an energy storage action, the second driving disc and the second rotating shaft do not act, and the corresponding second moving contact cannot act; when the common electric brake is needed, the second excitation switch acts to push the third deflector rod to make the driving plate rotate reversely and return to the original position, and the switch returns to the double-brake state again. At the moment, if standby power switching-on is needed, the second excitation switch firstly acts, the driving plate is pushed to rotate reversely through the second driving lever at the first time, the first gear and the second gear rotate along with the first gear, the second rotating disc drives the second driving pin to act only through the fifth arc-shaped groove in the reverse rotation at the initial rotation stage of the second gear, so that the second swing arm swings forwards, the second energy storage spring performs energy storage action, at the moment, due to the existence of the sixth arc-shaped groove, the second driving disc does not act, 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, the second driving disc and the second driving shaft are driven to rotate forwards, so that the second moving contact and the second fixed contact are closed, standby power switching-on is realized, when the second swing arm rapidly swings forwards, due to the existence of the fifth arc-shaped groove, the second rotating disc does not rotate forwards any more, the intermediate gear and the drive plate can stay in the original positions; in addition, in the process of the standby power switching-on action, although the first gear can drive the first rotary disc to reversely rotate, the third arc-shaped groove of the first rotary disc makes a abdicating action, the first swing arm cannot swing due to the reverse rotation of the first rotary disc, the first energy storage spring cannot perform an energy storage action, the first driving shaft and the first rotary shaft do not act, and the corresponding first moving contact cannot act; when the standby power is needed to be switched off, the first excitation switch acts to push the fourth deflector rod to enable the driving plate to rotate forward and return, and the switch returns to the double-brake state again. The excitation switch comprises an excitation coil (not shown in the figure) and a movable iron core, the excitation coil is wound on a coil framework, the movable iron core moves along the hollow of the coil framework, the two movable iron cores are connected with shifting pieces 7, the movement of the shifting pieces drives the first shifting rod or the second shifting 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 excitation coil to generate a magnetic field after being electrified, so that the magnetic field is used for adsorbing the movable iron core to move linearly along the hollow of the framework, and further drives the first driving lever or the second driving lever to move.
The above structure has the following drawbacks: 1. the output of the excitation switch is unstable, and the main reason is that the connection structure of the movable iron core and the shifting piece is not reliable enough, and the shifting piece is loosened to influence the output stroke; 2. the transmission is unreliable, in the process of driving the first rotating disc and the second rotating disc, the movable iron core generally rotates for a certain angle (about 60 degrees) due to the stroke reason, when the temporary point state is passed after the energy storage spring is driven to be compressed, the situation of blocking and stagnation exists, the energy storage spring cannot smoothly pass the temporary point after being compressed to release energy, and the switching failure is caused.
