Description
Technical field
The utility model is particularly related to a kind of the application in the permanent magnet mechanism can open the permanent-magnetic switching driving control device of shutoff to permanent-magnetic switching.
Background technology
Traditional low-voltage power control switch mainly adopts air circuit or A.C. contactor, air circuit adopts the spring energy-storage operating mechanism to carry out branch, closing operation, but spring operating mechanism exists parts many, the requirement on machining accuracy height, complex manufacturing can not be used in the occasion of frequent movement.A.C. contactor also is a kind of Electromagnetically-operating switch, and is simple in structure but drive system inertia is bigger, and the back coil that closes a floodgate still needs consumed power; Defectives such as air circuit and A.C. contactor also exist make-break capacity low, and the contact is fragile.The permanent-magnetic switching controller occurred, but existing permanent-magnetic switching controller circuitry complexity cause required outer electric capacity capacity big, so volume is big for this reason, the maintenance inconvenience is installed; And do not have on/off switch electric capacity in the controller, need at equipment outer engagement separating brake electric capacity, there is potential safety hazard in the lead-in wire trouble; The just discharge of when control electric capacity underfill of closing a floodgate causes that capacity loss is big, the life-span short.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, volume is little, power consumption is little, efficient is high, the permanent-magnetic switching driving control device of safe and reliable, long service life.
The permanent magnet mechanism switch drive control device that the utility model relates to, comprise the combined floodgate storage capacitor, the separating brake storage capacitor, contacting controling circuit and sub-gate control circuit, its special character is: the input at combined floodgate storage capacitor and separating brake storage capacitor is connected to the boosted switch power circuit, the input of boosted switch power circuit is the power input of this permanent magnet mechanism switch drive control device, be connected to involutory sub-gate control circuit and sub-gate control circuit provides order to control the main control circuit of the blanking time that allows on/off switch simultaneously at the control end of contacting controling circuit and sub-gate control circuit, described main control circuit adopts the power end of single-chip microcomputer and main control circuit to be connected to auxiliary power circuit, and described auxiliary power circuit is by energy storage separating brake capacitances to supply power.
Above-mentioned permanent magnet mechanism switch drive control device is connected to the demonstration output unit of being powered by auxiliary power circuit at the main control circuit output.
The utility model has the advantages that:
1, circuit structure is simple, and therefore required on/off switch capacitance is little, and the electric capacity volume is little like this, can be installed in the controller, maintenance is installed conveniently; There is not too much wiring, therefore safe and reliable, no potential safety hazard.
2, because main control circuit adopts single-chip microcomputer, and antijamming capability is strong, error is little, stability is strong, has the failure data protection function, circuit loss is lower, it is higher to discharge and recharge conversion efficiency.
3, by the boosted switch power circuit input voltage is promoted voltage stabilizing at 200V～220V adjustable dc voltage, can reduce electric current, play metering function, be convenient to main control circuit and control, reduce to disturb; The time that discharges and recharges is short, and combined floodgate electric capacity and separating brake electric capacity charge to time≤14s of 200V simultaneously from 0V; The fluctuation range of the voltage after boosting by Switching Power Supply is chargeable to 〉=200V (can not voltage stabilizing) to combined floodgate electric capacity and separating brake electric capacity in 70%～90% the time, and combined floodgate electric capacity and separating brake electric capacity charge to time≤20s of 200V simultaneously from 0V; When power cut-off to capacitor discharge, electric capacity discharges into time≤100s of 22V from 220V.After the boosted switch power circuit charges to storage capacitor, when input on/off switch signal, judge whether to satisfy the on/off switch condition by main control circuit, and signal passed to contacting controling circuit (or sub-gate control circuit), contacting controling circuit (or sub-gate control circuit) discharges to closing coil (or switching winding), has finished the drive controlling of switch like this.Because on/off switch electric capacity obtains the on/off switch signal and just discharges and carry out on/off switch control, little, the long service life of capacity loss under full condition.
4, have wide range of applications, be applicable to reliability requirement height, the frequent place of operation, can be widely used in systems such as electric power, colliery, iron and steel, oil, railway.
