Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment 1:
As Figure 1-Figure 2.
Load power down delay circuit system, comprise the resistance R1 that a resistance is more than or equal to 20K ohm, the input of resistance R1 is connected with the power supply U1 of a 15V, also comprise a dynamic circuit connector type relay K 1, the coil two ends of dynamic circuit connector type relay K 1 are contact 1, contact 2 respectively, the armature two ends of dynamic circuit connector type relay K 1 are contact 3 and contact 4 respectively, wherein, contact 1 is connected to the output of resistance R1, ground connection after the tandem tap J1 of contact 2, contact 3 meets power supply U1, ground connection after the series load S1 of contact 4, and the output of resistance R1 is also in series with ground connection after electric capacity C4.
As the comparison of Fig. 1 and Fig. 2, the course of work of the present utility model is: during initial condition, switch J1 is in off-state, the electric current of power supply U1 is by entering electric capacity C4 after resistance R1, electric capacity C4 is in charged state, when after electric capacity C4 charging complete, Closing Switch J1, this resistance due to resistance R1 is high, it can play the object of step-down, now, electric capacity C4, the coil of dynamic circuit connector type relay K 1, switch J1 forms closed-loop path, the coil of dynamic circuit connector type relay K 1 is in electriferous state, now, dynamic circuit connector type relay K 1 produces magnetic, the armature of dynamic circuit connector type relay K 1 closes, make power supply U1 through armature, through overload S1, now load S1 is in conduction operating state, electric capacity C4 is in continuous discharge state, after a period of time, the electricity of electric capacity is not enough to drive the armature of dynamic circuit connector type relay K 1 to close, this is that armature disconnects, load S1 power-off does not work.At this moment, want to restart load S1, then, need cut-off switch J1, make electric capacity C4 be in charged state, after making electric capacity C4 charging complete, again after Closing Switch J1, load S1 can be made again to work.Operation like this, can make load S1 after Closing Switch, just disconnects after a period of time, plays the object that load S1 closes after automatic time delay after a period of operation.
The resistance of resistance R1 here must be more than or equal to 20K ohm.If after being less than 20K ohm, the pressure drop at resistance R1 two ends does not reach requirement, now the electric current of power supply U1 constantly charges to electric capacity C4 after resistance R1, electric capacity constantly discharges again simultaneously, at this moment can reach a balance point voltage, namely, the voltage of the input of electric capacity C4 is become the definite value that is less than 15V, this definite value still can drive dynamic circuit connector type relay K 1 to produce enough large magnetic force, thus causes armature to close, and so just can not reach the object of time-delay closing load S1.Therefore resistance R1 must be the resistance of a large resistance, and its resistance is the bigger the better.
