Fig. 1 is circuit block diagram of the present utility model;
Fig. 2,3 is respectively the circuit theory diagrams of mechanical switch SW in the utility model, electronic switch SCR.
Embodiment
A kind of Intelligent EDDY Current is touched speed-sensitive switch, comprises the mechanical switch SW and the electronic switch SCR that are in parallel, and the signal output part of the first controller 3 links to each other with the control end of mechanical switch SW, and the signal output part of second controller 4 links to each other with the control end of electronic switch SCR.As shown in Figure 1.
As shown in Figure 2, described mechanical switch SW comprises vacuum interrupter 1, the one end links to each other with electronic switch SCR, its other end passes the first coil L1 and links to each other with metal dish 2, metal dish 2 is between first and second coil L1, L2, the output of the first controller 3 links to each other with first and second coil L1, L2 respectively, and the other end of the second coil L2 links to each other with electronic switch SCR.The switch contact of mechanical switch SW is made of vacuum interrupter 1, machinery pulling mode is the electromagnetic type pulling, when divide-shut brake, the first controller 3 is given first and second coil L1, L2 discharge, produce high-frequency current and high frequency magnetic field, under the effect of high frequency magnetic field, very large eddy current appears in metal dish 2 inductions that close on, eddy current is under the effect in magnetic field, produce very large repulsion electric power, promote metal dish 2 high-speed motions, thus the switch contact of pulling vacuum interrupter 1, just can finish minute, closing operation so that branch wire time is less than 10ms.Not only speed improves several times than normal circuit breaker, compare employed spring operating mechanism moving component with normal circuit breaker and reduce 80%, and use simple rectilinear motion, do not have complicated transmission mechanism, it is minimum to wear and tear, so that mechanical endurance and reliability improve.
As shown in Figure 3, described electronic switch SCR is composed in series by a plurality of bidirectional triode thyristors, reaches the electric requirement electric pressure, and the signal output part of second controller 4 links to each other with the control end of each bidirectional triode thyristor respectively.The number of described bidirectional triode thyristor is 10, is respectively bidirectional triode thyristor SCR1～bidirectional triode thyristor SCR10, and the signal output part of second controller 4 links to each other with the control end of bidirectional triode thyristor SCR1～bidirectional triode thyristor SCR10 respectively.
Be further described below in conjunction with Fig. 1,2,3 pairs of the utility model.
When needs close a floodgate, first and second controller 3,4 sends instructions respectively simultaneously to mechanical switch SW and electronic switch SCR, the speed of electronic switch SCR is nanosecond, greatly have precedence over mechanical switch SW, after electronic switch SCR conducting, the voltage of this switch ends becomes the pressure drop of thyristor conducting, can ignore with the superhigh pressure ratio; This moment, mechanical switch SW can finish combined floodgate smoothly, can not have the phenomenon of high-tension electricity arcing electric arc, added the protection of vacuum interrupter 1, and the contact life-span that makes mechanical switch SW is greater than 10000 times of ordinary tap.When mechanical switch SW finishes when closing a floodgate, switch ends voltage drops to relative 0V, thereby this moment, electronic switch SCR disconnected electronic switch SCR because of the pressure drop reason of thyristor, and electric current flows through from mechanical interrupteur SW.
When the needs separating brake; first and second controller 3,4 sends instructions respectively simultaneously to mechanical switch SW and electronic switch SCR; the arc voltage that mechanical switch SW slightly pulls open generation is during greater than the thyristor pressure drop; at this moment electric current flows through from thyristor; the arc voltage that mechanical switch SW is produced is very low, adds the protection of vacuum interrupter 1 so that the separating brake undertension burns contact to produce electric arc.When last the cycle electric current that flows through this switch after separately as mechanical switch SW crossed at 0, thyristor automatically shut down without afterflow, and this moment, this switch was finished separating brake.
In a word, the utility model when the switch divide-shut brake, first and second controller 3,4 of mechanical switch SW and electronic switch SCR send respectively the command signal control switch deciliter, touch speed-sensitive switch thereby consist of Intelligent EDDY Current.Switch branch wire time of the present utility model is nanosecond, can not only be as the switch of quick protection, even also can not produce switching overvoltage during divide-shut brake and shove, thereby protected the electrical network electric equipment, so that the electric equipment life-span increases; Broken through the switch off time restriction of regular tap, electrical network has been played safety and stabilization.
