Description
Technical field
The utility model relates to the power source conversion technical field, a kind of specifically automatic bur-translator.
Background technology
At present, the power supply changeover device of being sold on the market, portion is provided with a toggle switch within it, and its function is in the different area of power standard, selects different gears.For example, this place is the 110V/AC power supply, use the electric equipment of 220V/AC.Before use, toggle switch is allocated to the position of 110V, the electric equipment of 220V/AC could be inserted on the power supply changeover device then and use, and output voltage has only 110V or 220V.The defective of this type of power supply changeover device is a complex operation; easy manual operation mistake; in 220V power supply area toggle switch is allocated to the 110V gear; output 440V high voltage; but moment is burnt any power consumption equipment, serious threat user's the life and the safety of property, and existing power supply changeover device shortcoming defencive function; the operating state indication is incomplete, has serious potential safety hazard.
The utility model content
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of automatic bur-translator.
The purpose of this utility model is achieved by the following technical solution:
A kind of automatic bur-translator, comprise power input, voltage conversion device, power output end, described voltage reforming unit be provided with detect and the sample circuit of output information, according to the output information of this sample circuit send instruction treatment circuit, carry out the actuating circuit of this treatment circuit instruction.
As optimal technical scheme of the present utility model, described sample circuit comprises operational amplifier, and this operational amplifier is provided with operational amplifier A unit and operational amplifier B unit.
As optimal technical scheme of the present utility model, described actuating circuit is provided with indicator light.
As optimal technical scheme of the present utility model, described indicator light is red and green diode indicator light.
Compared with prior art; establish sample circuit, treatment circuit and actuating circuit in the power supply changeover device in the utility model; can realize the automatic conversion of mode of operation; and can export the power supply of 110V and 220V simultaneously; have high and low pressure, temperature protection function concurrently; the user can also pass through diode indicator light, the operating state of checking power supply changeover device easily.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the circuit theory diagrams of the utility model automatic bur-translator.
Embodiment
See also Fig. 1, be the circuit theory diagrams of the utility model automatic bur-translator.GND connecting to neutral line among the figure, OUT/110 connect 110V output, and T/110 connects transformer 110V tap, and IN/L connects the input live wire, and OUT/220 connects 220V output, and T/220 connects transformer 220V tap.
This automatic bur-translator has two kinds of mode of operations, when sampled voltage (U1B/6 pin) is lower than reference voltage (U1B/5 pin), the U1B/7 pin is output as high level, this moment, the Q5 base stage was a high level, Q5 conducting RL2 two ends power supply is set up, the RL2 adhesive will be imported and insert T/110, and be the 110V mode of operation this moment; When sampled voltage (U1B/6 pin) is higher than reference voltage (U1B/5 pin), the U1B/7 pin is output as low level, this moment, the Q5 base stage was a low level, Q5 disappears by RL2 two ends power supply, RL2 discharges to import and inserts T/220, be the 220V mode of operation this moment, the automatic conversion of two kinds of mode of operations finishing thus.
If civil power sudden change (reducing or rising) occurs, when the sampling output voltage lower, make the D7 negative electrode be lower than anode voltage D7 conducting, U1A/3 pin voltage is lower than the U1A/2 pin, and U1A/1 pin output low level, Q4 base stage also are low level, Q4 ends, RL1 and RL3 power supply disappear, and RL1 and RL3 discharge simultaneously, carry out low-voltage variation; Higher when the output voltage of sampling, make the D8 anode be higher than negative electrode D8 conducting, U1A/2 pin voltage is higher than the U1A/3 pin, U1A/1 pin output low level, Q4 base stage are low level also, and Q4 ends, RL1 and RL3 power supply disappear, and RL1 and RL3 discharge simultaneously, avoid the too high power consumption equipment that burns out of output voltage.
In the circuit operate as normal, if institute's bringing onto load surpasses nominal load or low-voltage band full load etc., the transformer temperature raises fast, 120 ℃ of normally closed temperature detect switch (TDS)s that are located at transformer inside disconnect, and so 1 pin of JP4,2 pin open circuit disconnect relay R L1, RL3 power supply, RL1 and RL2 discharge simultaneously, disconnect output, avoiding transformer Yin Wendu too high, and burn.
When exporting 110V and 220V power supply simultaneously, RL1 and RL3 insert transformer 220V and 110V tap respectively, and RL1 and RL3 adhesive can obtain corresponding output voltage at the output of correspondence, are convenient to the power consumption equipment that the user uses two kinds of different electrical power voltages simultaneously.
The JP1/1 of this automatic bur-translator connects the anode of red and green LED, and JP1/2 connects the negative electrode of green LED, and JP1/3 connects the negative electrode of red light emitting diodes.During use, if circuit is normal, 1 pin of JP1 is higher than 2 pin voltages, and green LED is lighted, and it is normal that this is designated as power supply; If temperature protection, when high and low pressure protection or circuit broke down, the Q6 base stage was high level Q6 conducting; 1 pin of JP1 is higher than 3 pin voltages; red light emitting diodes is lighted, and this is designated as fault, therefore can be by the clear and definite operating state of judging power supply changeover device of the indication information of diode.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
