Abstract
The utility model relates to a failure alarming apparatus for earth leakage mechanicals which comprises an electrical apparatus release driving coil, a rectifier voltage stabilizing circuit, an integrated amplifier, a thyristor. Further, the utility model increases an alarming element. The utility model has the advantage that when an electrical apparatus release has a breakdown, the device emits warning and protects the electrical apparatus release.
Description
Affiliated technical field:
The utility model belongs to a kind of warning device of residual current circuit breaker.
Background technology:
At present; existing residual current circuit breaker electric leakage mechanical fault protective device; be to constitute by electrical apparatus release field coil, thyristor, integrated amplifier, regulator rectifier circuit etc.; this electric leakage mechanical fault protective device can only produce when electric leakage and thread off, and does not possess electric leakage and the malfunctioning generation of tripping mechanism takes place and the system of alarm.Therefore, caused leakage tripping device to burn and the user does not know the defective of preventing in long-time energising.
Summary of the invention:
The purpose of this utility model just provides a kind of when electrical apparatus release breaks down, and can give the alarm and protect the electric leakage mechanical fault warning device of electrical apparatus release.
For achieving the above object, the utility model is taked really, and technical scheme is: a kind of electric leakage mechanical fault warning device, it comprises the electrical apparatus release field coil, regulator rectifier circuit, integrated amplifier, thyristor, the regulator rectifier circuit input end connects AC power, its output terminal connects the integrated amplifier input end, also be connected in series an electrical apparatus release field coil and thyristor on the AC power, the thyristor control utmost point is connected with integrated amplifier, the output terminal of regulator rectifier circuit also is serially connected with another controlled thyristor, also be equipped with one on the electrical apparatus release field coil with coil unshakable in one's determination, one end of coil is connected with the controlled thyristor control utmost point by a diode, the other end is connected with the base stage of a triode, and the collector of triode also is connected with the control utmost point of thyristor.
In circuit, increased alarm element owing to the utility model compared with prior art, can the alarm failure signal.And the utility model also utilizes the break-make of thyristor to make trip coil when reporting to the police, power-off protection leakage tripping device.Improve the performance of isolating switch, increased the earth leakage protective sense of security.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done further detailed description.
Accompanying drawing is the circuit theory diagrams of the utility model electric leakage mechanical fault warning device.
Embodiment
Electric leakage mechanical fault warning device shown in the drawings is by electrical apparatus release field coil KC, coil 3, regulator rectifier circuit 2, integrated amplifier 1, thyristor SCR1, controlled thyristor SCR2, triode Q1 and loudspeaker MIC, LED 1 formation such as grade, the model of integrated amplifier 1 is that the output terminal of M54123 regulator rectifier circuit 2 is serially connected with a controlled thyristor SCR2, be equipped with on the electrical apparatus release field coil KC with coil 3 unshakable in one's determination, coil 3 one ends are connected with the control utmost point of controlled thyristor SCR2 by a diode D1, another termination triode Q1 base stage and thyristor SCR1 anode are with the break-make of I Q1 of control triode.
Be serially connected in and also be serially connected with loudspeaker MIC and LED 1 on this loops of controlled thyristor SCR2 of regulator rectifier circuit 2 output terminals and be used to leak electricity coil when producing induced voltage, send alerting signal.
When electric leakage signal, thyristor SCR1 conducting, electrical apparatus release field coil KC energising, coil 3 output signals.Can not thread off as tripping mechanism this moment; controlled thyristor SCR2 conducting; loudspeaker MIC, LED 1 give the alarm; simultaneously; noble potential also appears in triode Q1 base stage, triode Q1 conducting, the extremely same anode in short circuit of the control of thyristor SCR1; thyristor SCR1 disconnects, and has protected leakage tripping device.
