Description
Technical field
The utility model relates to a kind of low-power consumption power-failure protecting switch.
Background technology
At present; most of automatic control equipment all has Powercut self locking power, incoming call idle function or similar defencive function; to avoid in the unattended situation of equipment, through having a power failure, carrying out electric process, entering wrong running status, damage equipment, workpiece or cause the danger such as fire.But some power consumption equipment does not have this function, such as motor or electric heater, water pump, transformer or the Switching Power Supply etc. controlled with single earth leakage circuit-breaker, air switch.Therefore there is above-mentioned safety problem in these equipment.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of low-power consumption power-failure protecting switch, it has, and volume is little, cost is low, low in energy consumption, without distribution box, the feature such as easy for installation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: comprise step-down rectifier voltage stabilizing circuit, step-down rectifier voltage stabilizing circuit output loop series direct current relay or solid-state relay and the electronic switch being comprised of one-way SCR and subsidiary component thereof; Electronic switch comprises: high potential link is through the anodic bonding of normally closed button and one-way SCR, high potential link also often leaves button and is connected with the control utmost point of one-way SCR after being connected in the divider resistance dividing potential drop between high potential link and electronegative potential link, and electronegative potential link is connected with the negative electrode of one-way SCR; High potential link and electronegative potential link are serially connected with step-down rectifier voltage stabilizing circuit output loop.
The utility model further improves and is: direct current relay or solid-state relay are positioned at the hot end of step-down rectifier voltage stabilizing circuit output loop; Step-down rectifier stabilized circuit outputting voltage is 24V direct voltage.
The beneficial effect that adopts technique scheme to produce is: the direct current relay or the solid-state relay that play Powercut self locking power, incoming call standby effect carry out switch control by one-way SCR; made up non-automatic control appliance under unattended state, have a power failure unprotect, incoming call self-starting functional defect; and the control mode such as relatively traditional magnetic starter, A.C. contactor, it has again, and volume is little, cost is low, low in energy consumption, without distribution box, the advantage such as easy for installation.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Embodiment
Embodiment is as shown in Figure 1 known, comprises step-down rectifier voltage stabilizing circuit, step-down rectifier voltage stabilizing circuit output loop series direct current relay K M and the electronic switch being comprised of one-way SCR KG1 and subsidiary component thereof; Electronic switch comprises: high potential link A is through the anodic bonding of normally closed button SB2 and one-way SCR KG1, high potential link A also often leaves button SB1 and is connected with the control utmost point of one-way SCR KG1 after being connected in divider resistance R1 between high potential link A and electronegative potential link B, R2 dividing potential drop, and electronegative potential link B is connected with the negative electrode of one-way SCR KG1; High potential link A and electronegative potential link B are serially connected with step-down rectifier voltage stabilizing circuit output loop; Direct current relay or solid-state relay are positioned at the hot end of step-down rectifier voltage stabilizing circuit output loop; Step-down rectifier stabilized circuit outputting voltage is 24V direct voltage.
Using method and operation principle:
Step-down rectifier voltage stabilizing circuit is connected with needing the power supply (electric main) of controlling, the normally opened contact of direct current relay KM is series in the power supply (electric main) that needs to control, make it power supply play switch control action.
Electric main becomes 24V direct current through rectification, filtering.Now one-way SCR KG1 is not because there is no trigger voltage in cut-off state, and direct current relay KM is failure to actuate, and the normally opened contact of direct current relay KM disconnects, and electric main disconnects, and there is no electric power output.If operator presses and often opens button SB1 ,+24V voltage is supplied with one-way SCR KG1 and is controlled triggering signal of the utmost point, one-way SCR KG1 conducting immediately after R1/R2 dividing potential drop by KM coil.It is electric that its conducting obtains direct current relay KM, and the normally opened contact of direct current relay KM is closed, and controllable silicon KG1 has self-sustaining characteristic, even if now operator unclamps and often opens button SB1, controllable silicon KG1 also can remain on conducting state, and controlled electric equipment energising, has completed power initiation operation.
If operator presses normally closed button SB2, direct current relay KM coil opens circuit, and controllable silicon KG1 loses forward voltage and exits conducting state.The normally opened contact of direct current relay KM disconnects, even if now unclamp normally closed button SB2, controllable silicon KG1 also can remain on cut-off state, has completed power supply opening operation.
If electric main power-off; step-down rectifier voltage stabilizing circuit Non voltage output; direct current relay KM coil opens circuit; the normally opened contact of direct current relay KM disconnects; power supply is cut off; even if now civil power recovers again; owing to often opening button SB1 in off-state; controllable silicon KG1 trigger electrode does not have trigger voltage; controllable silicon KG1 also can be in cut-off state; direct current relay KM also can remain open state, thereby has protected controlled device to be unlikely to unexpected electric and enter wrong running status, makes equipment in Powercut self locking power state.
