Description
Technical field
The utility model relates to a kind of voltage stabilizer, specifically relates to a kind of liquid crystal type relay-type voltage stabilizer.
Background technology
As everyone knows, which place voltage is not had not fluctuate with the peak valley of electricity consumption, by 170--180V to 240--250V, each different to the greatest extent, in special cities and towns, general voltage is all higher than 220V, during the late into the night, voltage can be higher, such words consumes all large on the impact of circuit and electrical equipment, in recent years with the fast development of scientific and technological industry, many precision equipments are all widely used, the traditional industry of the requirement of high-tech industry to custom power quality is also strict many, and power quality problem is also very many, as instantaneous power failure, overtension is too low, noise, frequency jitter, voltage flicker and harmonic wave etc. the accident that various power quality problem causes high-tech manufacturers produce to be paused, in time, hears of, and it is also serious more than other problem, therefore how to go to improve power quality to cause damage because of pause to avoid highly difficult scientific and technological manufacturer, become the important subject of current electric power circle and high-tech industry, and in the bad phenomenon of power quality, spread of voltage is had the most easily to occur, therefore good alternating current equipment is developed necessary.
In current power quality, the problem of associated voltage shakiness probably can be divided into overtension, too low, rapid drawdown, jump, flicker and the problem such as instantaneous power failure, long-time variation in voltage peak of power consumption sooner or later usually, or supply electric power changes and happens occasionally, situation like this also has a lot, all damage and the person can be caused to bring harm to power equipment.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly exports the liquid crystal type relay-type voltage stabilizer that voltage stabilizing is more stable, digital lcd shows more visualize.
For solving the problem, delay setting circuit, input detecting circuit that the technical solution adopted in the utility model comprises central processing unit and controls by it, described central processing unit is connected to LCDs unit, it is characterized in that: the input end of described voltage stabilizer is connected to Switching Power Supply, powered to back-end circuit by Switching Power Supply, voltage voltage stabilizing is kept by voltage stabilizing driver element, the output unit of described voltage stabilizing driver element rear end has load detecting circuit, output detection circuit, temperature sensing circuit, and the signal feedback of described temperature sensing circuit is in central processing unit.
Described liquid crystal type relay-type voltage stabilizer; it is characterized in that: described LCDs unit comprises LCD display in described LCD display, having time delay display unit, overvoltage display unit, temperature protection display unit, load display unit, overload display unit, under-voltage display unit.
Described liquid crystal type relay-type voltage stabilizer, is characterized in that: described voltage stabilizing driver element is made up of the relay controlled by central processing unit and main-transformer.
As follows by liquid crystal type relay-type voltage stabilizer advantage of the present utility model: Switching Power Supply part, more stable circuit below of giving is powered, and the adhesive of voltage stabilizing relay and central cpu processor control, and keep voltage voltage stabilizing.Keep voltage voltage stabilizing by voltage stabilizing driver element, the output unit in voltage stabilizing driver element rear end arranges and carries testing circuit, output detection circuit, temperature sensing circuit, and the signal feedback of temperature sensing circuit is in central processing unit.By such scheme, overcome the problem of prior art, provide a kind of rational in infrastructure, output voltage stabilization, multifunction protection, the liquid crystal type electronic relay formula voltage stabilizer that digitizing intuitively shows, thus solve the deficiency existing for traditional voltage stabilizer.
Accompanying drawing explanation
Below in conjunction with Figure of description, the utility model is described further.
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, liquid crystal type relay-type voltage stabilizer of the present utility model, comprise central processing unit 1, and by the delay setting circuit 2 that it controls, input detecting circuit 3, described central processing unit 1 is connected to LCDs unit, the input end of described voltage stabilizer is connected to Switching Power Supply 5, powered to back-end circuit by Switching Power Supply 5, voltage voltage stabilizing is kept by voltage stabilizing driver element 6, the output unit of described voltage stabilizing driver element 6 rear end has load detecting circuit 7, output detection circuit 8, temperature sensing circuit 9, the signal feedback of described temperature sensing circuit 9 is in central processing unit 1.
Described LCDs unit comprises LCD display 4, has time delay display unit 401, overvoltage display unit 402, temperature protection display unit 403, load display unit 404, overload display unit 405, under-voltage display unit 406 in described LCD display 4.Described voltage stabilizing driver element 6 is made up of the relay controlled by central processing unit 1 and main-transformer, by the adhesive of relay, keeps voltage voltage stabilizing.
The basic functional principle of Switching Power Supply: Switching Power Supply is by output voltage " sampling "; and " comparison " carried out to reference source control " Correctional tube " or " switching tube " afterwards; now " switching tube " of Switching Power Supply is equivalent to a switch, and service time is determined by comparative result; When the voltage that Switching Power Supply exports is too low, makes " switching tube " service time elongated by " comparing amplification " control " control circuit switching time ", thus the voltage of output is promoted.
Described in upper, not any pro forma restriction is done to the utility model, although the utility model discloses as above with better case study on implementation, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when the structure and technology contents that can utilize above-mentioned announcement are made a little change or be modified to the equivalent case study on implementation of equivalent variations, but every content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above case study on implementation, equivalent variations and modification, all still belong to technical solutions of the utility model scope.
