Embodiment
As depicted in figs. 1 and 2; The stabilized rectifier of the tape jam indicating device of the utility model; Comprise rectifying and voltage-stabilizing operating circuit, diagnostic circuit, protective circuit and warning device; The input of said rectifying and voltage-stabilizing operating circuit is connected with magneto, and output is connected with load, and said diagnostic circuit is connected with the rectifying and voltage-stabilizing operating circuit; Said protective circuit is arranged between rectifying and voltage-stabilizing operating circuit and the load circuit, and the control end of protective circuit is connected with the output of diagnostic circuit; The malfunction indicator lamp of said warning device is connected with diagnostic circuit.Wherein, Said diagnostic circuit comprises transistor VT, electrochemical capacitor C01, resistance R 01, resistance R 02, light-emitting diode VD1, voltage stabilizing didoe VD2 and relay; The emitter of said transistor VT is connected with the positive pole of rectifying and voltage-stabilizing operating circuit; Collector electrode is contacted respectively and is connected with the negative pole of rectifying and voltage-stabilizing operating circuit behind connecting resistance R02 and the light-emitting diode VD1, is connected with negative pole with the positive pole of rectifying and voltage-stabilizing operating circuit respectively with resistance R 01 through electrochemical capacitor C01 behind the base stage series connection voltage stabilizing didoe VD2; The coil JL of said relay is parallelly connected with light-emitting diode VD1; The normally-closed contact JK of relay is arranged in the protective circuit; Control the disconnection of normally-closed contact JK through the coil JL of relay, thereby stop with realization other components and parts of motor circuit system to be protected for the load circuit power supply.
Fig. 2 is the circuit theory diagrams of the utility model.As shown in Figure 2, in the fault diagnosis circuit: light-emitting diode VD1 adopts a 12V red light emitting diodes as superpressure situation indicator light; Voltage stabilizing didoe VD2 adopts the voltage stabilizing didoe of 14.5V, and the resistance of current-limiting resistance R01 and R02 is respectively 450 Ω and 980 Ω; It is the PNP triode of A1013 that transistor VT adopts model, and the model of electrochemical capacitor C01 is 25V47 μ F, and relay coil JL is a 12V direct current relay coil.Above parameter can reset according to the structure and the parameter of rectifying pressurizer.
