Described overheat protector loop comprises the electric capacity 12 and temperature detecting resistance 13 that are arranged in parallel; The output 14 in described overheat protector loop is also provided with a resistance in parallel with temperature detecting resistance 13.
Described over-current detection loop comprises resistance 23 and the amplifier 24 of series connection, the input 21 in described over-current detection loop has also been arranged in parallel a resistance 22 and an electric capacity, the output of described resistance 23 has been arranged in parallel No. two electric capacity, and the output of described amplifier 24 has been arranged in parallel No. two resistance 25 and No. two electric capacity.
The output of described amplifier has also been arranged in parallel No. three electric capacity, and the other end of described No. three electric capacity is connected with a 5V power supply.
The below lower operation principle of the present utility model of summary:
When the 3rd resistance 3, the 4 pairs of input voltage samplings of the 4th resistance of the input in input voltage measurement loop, dividing potential drop, last integrated circuit (IC) chip detect the voltage that the output 6 in input voltage measurement loop receives and judge, when detection voltage is excessive, then Signal transmissions is given one of them LED by integrated circuit (IC) chip, LED display is red, and expression makes mistakes; If non-overvoltage, then Signal transmissions is given an another LED by integrated circuit (IC) chip, and LED display is green, represents and does not make mistakes.
Same; in overheat protector loop, input 11 carries out the change of resistance by the change of temperature in circuit by temperature detecting resistance 13; affect the magnitude of voltage in circuit simultaneously; the voltage that the output 14 of integrated circuit (IC) chip to overheat protector loop receives detects, judges, and corresponding Signal transmissions is carried out display that is red, green light to LED.
Described over-current detection loop is by the electric current of input 21, by the sampling of a resistance 22 pairs of electric currents, if electric current is excessive, magnitude of voltage in circuit can increase accordingly, the voltage that now output 26 of integrated circuit (IC) chip to over-current detection loop receives judges, thus judge electric current whether overcurrent, if overcurrent, LED shows redness, and prompting makes mistakes; If non-overcurrent, then LED display is green.
