Abstract
Provided is an output and input dual-protection system structure of an alternating current voltage stabilizer. An input protection controller module, a voltage-stabilizing and computing control module and an output protection controller module are sequentially connected between an input end Vin and an output end Vout, the time-delay circuit module is arranged between the voltage-stabilizing and computing control module and the input protection controller module, and operation comparison is performed between sampled data of a temperature sampling module, a current sampling module and a voltage sampling module and a set protection threshold through the voltage-stabilizing and computing control module. If protection signals occur in an operation process of the alternating current voltage stabilizer, firstly output of the voltage stabilizer is closed by the output protection controller module so as to protect load devices preferentially, and then a period of time (such as 30 seconds to 300 seconds) is delayed. If a fault is maintained, a power supply of the whole voltage stabilizer is cut off by the input protection controller module to guarantee safe use of the alternating current voltage stabilizer. The output and input dual-protection system structure facilitate improvement of use reliability of the alternating current voltage stabilizer.
Description
Technical field
The utility model relates to a kind of protection system structure of AC voltage regulator, specifically relates to a kind of output and input duplicate protection system configuration of AC voltage regulator.
Background technology
Mostly the safeguard measure that conventional AC voltage regulator is taked is to cut off the output of pressurizer; Control principle is that voltage, electric current and the temperature signal of sampling AC voltage regulator and the protection threshold value of setting compare; When overvoltage, under-voltage, overcurrent and excess temperature reach threshold value, cut off the output of AC voltage regulator and bring in the purpose that realizes the protection power consumption equipment.Because this control mode is just cut off the output of AC voltage regulator; And that pressurizer inside still has is charged; If guard signal causes (destroying the excess temperature that causes, the overvoltage fault of the stuck initiation of motor etc. like turn-to-turn insulation) by the AC voltage regulator internal fault; Still can damage pressurizer, even initiation fire.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of output and input duplicate protection system configuration of AC voltage regulator is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of output of AC voltage regulator and input duplicate protection system configuration; Be connected with input protection controller module, voltage stabilizing and s operation control module and output protection controller module between the input Vin of said protection system and the output end vo ut in turn; Be provided with the delay circuit module between voltage stabilizing and s operation control module and the input protection controller module, also be connected with temperature sampling module, current sample module and voltage sample module on voltage stabilizing and the s operation control module.
The protection controller that the utility model increases at input can substitute the switch or the circuit breaker of conventional AC voltage regulator; This protection controling appliance has machinery or electronics auto-lock function; Can be manually opened with close; After opening it being applied this device of the signal of telecommunication can thread off automatically, needs hand-reset.The control principle of the utility model is, the running parameter of temperature sampling module, current sample module and voltage sample module continuous sampling AC voltage regulator, and carry out computing relatively by the protection threshold value of voltage stabilizing and s operation control module and setting; If close the output of pressurizer when guard signal has appearred in AC voltage regulator in the course of the work earlier by the output protection controller module; The priority protection load equipment; Delay time a period of time then (like 30s ~ 300s); Still keep then cutting off pressurizer complete machine power supply like fault, guarantee the safe handling of AC voltage regulator, help improving the dependability of AC voltage regulator by the input protection controller module.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: referring to Fig. 1; Be connected with input protection controller module, voltage stabilizing and s operation control module and output protection controller module between the utility model input Vin and the output end vo ut in turn; Be provided with the delay circuit module between voltage stabilizing and s operation control module and the input protection controller module, also be connected with temperature sampling module, current sample module and voltage sample module on voltage stabilizing and the s operation control module.
The control principle of the utility model is, the running parameter of temperature sampling module, current sample module and voltage sample module continuous sampling AC voltage regulator, and carry out computing relatively by the protection threshold value of voltage stabilizing and s operation control module and setting; If close the output of pressurizer when guard signal has appearred in AC voltage regulator in the course of the work earlier by the output protection controller module; The priority protection load equipment; Delay time a period of time then (like 30s ~ 300s); Still keep then cutting off pressurizer complete machine power supply like fault, guarantee the safe handling of AC voltage regulator, help improving the dependability of AC voltage regulator by the input protection controller module.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection range that belongs to the utility model.
