Abstract
The utility model discloses a kind of electric actuator with power-off under-voltage reset function, comprise casing, casing is with drive motors, drive motors is coordinated with actuator driven through-drive by transmission mechanism, it is characterized in that: stand-by power supply and external power supply are parallel to the control circuit of drive motors through both positive and negative polarity switching relay, the voltage of described external power supply and the voltage peak of stand-by power supply close, the positive pole of described external power supply connects the first insurance and diode, and described stand-by power supply is chargeable electric capacity.This electric actuator has the following advantages: 1, during external circuit short circuit because the existence of diode can not loss stand-by power supply, also play the effect of protection stand-by power supply; 2, can charge to stand-by power supply during outer power voltage height, there is no power-off at external power source, but outer power voltage lower than during backup power source voltage and automatically starting stand-by power supply work; 3, due to the protective effect of diode, even if also can not internal circuit be damaged when circuit misconnection.
Description
Technical field
The utility model relates to a kind of electric actuator with power-off under-voltage reset function.
Background technology
Conventional electric actuator generally comprises casing, casing is with drive motors, drive motors is coordinated with actuator driven through-drive by transmission mechanism, but external power interruptions or under-voltage time, the signal that adjuster sends also can interrupt thereupon, and suddenly power-off or cause controller to work easily causing economic loss because of under-voltage.
Utility model content
In view of the deficiency that background technology exists, technical problem to be solved in the utility model be to provide a kind of can external power cut-off or under-voltage time keep the electric actuator with power-off under-voltage reset function of work.
The utility model takes following technical scheme: the electric actuator with power-off under-voltage reset function, comprise casing, casing is with drive motors, drive motors is coordinated with actuator driven through-drive by transmission mechanism, stand-by power supply and external power supply are parallel to the control circuit of drive motors through both positive and negative polarity switching relay, the voltage peak of described external power supply and the voltage peak of stand-by power supply close, both coating-forming voltage comparison circuits, the positive pole of described external power supply connects the first insurance and diode, and described stand-by power supply is chargeable electric capacity.
The electric actuator of power-off under-voltage reset function that what the utility model provided have, has the following advantages: 1, during external circuit short circuit because the existence of diode can not loss stand-by power supply, also play the effect of protection stand-by power supply; 2, can charge to stand-by power supply during outer power voltage height, when outer power voltage is lower than stand-by power supply or power-off, automatically can starts stand-by power supply work, be conducive to the loss avoided because actuator power-off causes; 3, due to the protective effect of diode, even if also can not internal circuit be damaged when circuit misconnection.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The circuit theory schematic diagram with the electric actuator of power-off under-voltage reset function that Fig. 1 provides for utility model.
Embodiment
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the operation principle thereof of embodiment below more by reference to the accompanying drawings.
With reference to shown in Fig. 1, the electric actuator of power-off under-voltage reset function that what the utility model provided have, comprise casing, casing is with drive motors, drive motors is coordinated with actuator driven through-drive by transmission mechanism, stand-by power supply 1 and external power supply 2 are parallel to the control circuit of drive motors through both positive and negative polarity switching relay 3, the voltage peak of described external power supply 2 and the voltage peak of stand-by power supply close, both coating-forming voltage comparison circuits, the positive pole of described external power supply 2 connects the first insurance 4 and diode 5, external power supply 2 is parallel to both positive and negative polarity switching relay 3 through the first insurance 4 and diode 5, described stand-by power supply 1 is chargeable electric capacity, stand-by power supply 1 connects the second insurance 6, stand-by power supply 6 is parallel to both positive and negative polarity switching relay 3 through the second insurance 6.
The voltage peak of external power supply 2 usual is in the above-described embodiments 24 volts, and the peak of the voltage of described stand-by power supply 1 is 24 volts.
The operation principle of the electric actuator with power-off under-voltage reset function is described below in detail: when A, external power supply 2 normally work, as long as stand-by power supply 1 voltage is lower than external power supply 2, according to voltage compare principle, external power supply 2 can charge to stand-by power supply 1, and what power for control circuit is external power supply 2; When B, external power supply 2 voltage are lower than stand-by power supply 1 or power-off, automatically start power to control circuit according to voltage compare principle stand-by power supply 1, period both positive and negative polarity switching relay 3 commutation conversion both positive and negative polarity connects; When C, external circuit short circuit, there is stand-by power supply 1 and outwards cannot be exported by the diode 5 of one-way flow due to diode 5, avoids the loss of power, or avoids stand-by power supply 1 excessive and explode because immediate current exports; D, diode 5 itself have hypotensive effect, generally can reduce by 0.7 volt, if the voltage peak of stand-by power supply 1 is identical with the voltage peak of external power supply 2, stand-by power supply 1 voltage can be avoided to be in peak for a long time, are conducive to protecting stand-by power supply 1.
