The invention discloses a multidimensional vibration damper for a suspension bridge central buckle containing a viscoelasticity energy consumption component and metal rubber. Under the action of weak wind load or mid-small vibration, a propeller type energy consumption device moves in a cylindrical steel box under the driving of a main cable, and generates friction with a viscoelastic material in the steel box so as to reduce the influence of action on the main body structure of a suspension bridge; when the multidimensional vibration damper is under the action of strong wind load or great vibration, relatively great displacement is possible to appear in the horizontal direction, a limiting baffle is contacted with an annular rubber tie-plate on a wall of the cylindrical steel box to drive the steel box to rotate around a cuboid steel box supporting seat, at the moment, a part of the acting energy is adsorbed by the viscoelastic material between the supporting seat and angle iron, and the metal rubber, except for consuming a part of energy, can also prevent the whole central buckle structure from generating overlarge horizontal displacement, and enables the structure to restore after the load is removed. By the multidimensional vibration damper disclosed by the invention, the whole central buckle has relatively good plasticity, and damages to the main body structure of the suspension bridge are reduced.

The transformer anti-saturation control system comprises an oscillator used for outputting an open signal to open a power tube when the flyback switching power supply works; a peak value comparator used for transmitting a delay signal to a delay circuit when the sampling voltage of a CS sampling resistor is greater than a first voltage threshold; the delay circuit used for transmitting a detection signal to a saturation detection circuit according to the delay signal after delaying the scheduled time; an analog adder used for superposing the first voltage threshold and the preset superimposed voltage, and obtaining a second threshold voltage; the saturation detection circuit used for detecting the sampling voltage and the second threshold voltage when receiving the detection signal, and transmitting a first control signal to the oscillator when the sampling voltage is greater than the second threshold voltage; and the oscillator is further used for reducing the frequency of the open signal when receiving the first control signal, so as to prolong the turn-off time of the power tube. The transformer anti-saturation control system for the flyback switching power supply provided by the invention can reset a transformer in time when the transformer is in a saturation state.
