nullOperation principle of the present utility model is: after connecting civil power，220V line voltage is through transformator W transformation，When line voltage is normal，The contact K-1 of relay K connects not moved end 1，The now winding N1 of transformator、N2 and N3 all accesses circuit work，Voltage after transformation enters electric capacity C1 filtering，When voltage is normal，Undertension after resistance R2 and potentiometer RP1 dividing potential drop is so that audion V1 turns on，Therefore relay K is failure to actuate，When running into civil power overvoltage，Voltage after resistance R2 and potentiometer RP1 dividing potential drop is sufficient so that audion V1 conducting，Therefore relay K energising，Its contact K-1 connects not moved end 2，The now winding N1 of transformator、N2 accesses circuit work，Its secondary end winding reduces，Therefore output voltage reduces，Reach the purpose of under-voltage protection，Electric capacity C4 plays the effect of buffer protection，It can be avoided that the frequent movement of audion V1，IGCT Q1 turns off at ordinary times，LED lamp H does not works.As staff Touching electrode A, human body leakage current injects the base stage of V2 through high value resistor R5, makes V2 turn on rapidly, and C3 stores electric charge and charges to C2 through V2, and provides forward trigger current through R5 for Q1, and Q1 is open-minded, and lamp H lights luminescence.After Q1 opens, owing to R5 value is less, the leakage current of Q1 gate pole can charge to C2 through R5, so after staff leaves A, although V2 recovers cut-off, but C2 both end voltage will not be fallen, so Q1 remains to be held on state, H still lights luminescence.Now 220V alternating voltage mainly drops to H two ends, and the most a few volt of Q1 both end voltage, owing to Q1 uses micro-touch to send out unidirectional thyristor, so Q1 remains to maintenance work.If having a touch with B electrode slice with hands, human body leakage current injects V1 base stage through R4, makes V1 turn on, and C1 is stored electric charge and will be discharged rapidly by V1, and when being down to about 0.3V, Q1 is because losing forward trigger current, and when alternating current zero passage, Q1 i.e. turns off, and lamp H extinguishes.
