Abstract
The invention provides an abnormal fault flashing alarm indicating device of a grounding system. The device is matched with a leakage protector; an alarm indicating circuit is connected between a PE wire of an input end of the leakage protector and L and N wires; once a power utilization system has a fault and a voltage exists between the PE wire and the L or N wire, an alarm device immediately and automatically detects the grounding system; and when the grounding system has the fault, an alarm instruction is sent out and the alarm instruction can be eliminated until the leakage protector is separated from a power supply or the fault of a power supply system is completely eliminated. The abnormal fault flashing alarm indicating device of the grounding system can be widely applicable to household appliances and daily appliances to be used as safety power utilization protection.
Description
Technical field
The present invention relates to the safety technique for using electricity field, particularly a kind ofly the device that abnormal failure can send the warning indication of flicker occurs in earthed system.
Background technology
Earthed system is a protection system the most basic in the safety utilization of electric power, and so-called earthed system is exactly the independent supporting buried underground copper bars of an end of every building building; The other end is received respectively in the socket earth polar jack of every household; When plug was inserted into this socket, the earth polar copper pin on the plug was connected with hole, socket earth polar, the yellowish green guardwire of PE that is riveted on plug earth polar copper pin then with the palp metal parts of electrical equipment; For example shell connects, and forms a complete earthed system.There is the I electric appliances of grounding requirement all need use and is connected palp conductiving metal part with earthed system, let it keep no-voltage, to ensure user's personal safety.In case yet the earthed system appearance is unusual, for example occurs wiring error, socket or unexpected factors such as circuit damage and short circuit on the socket and all might make the earthed system part charged, thereby cause the electric shock casualty accident.Chinese invention patent " abnormal voltage occurring in earthed system is the device that can send the indication of reporting to the police "; Its license number is ZL200610123781.9; This patent only just connects the effect that phase line just plays the indication of reporting to the police to ground wire PE; When ground wire receive be connected to zero line as and can not send clear and definite warning indication, in case zero line has Yu Dianshi like this, just can not get safe guarantee.
Summary of the invention
The purpose of this invention is to provide a kind of earthed system abnormal failure flicker warning indicating device; This warning indicating device is contained on the earth leakage protective device and is mated work; When in case the using electricity system fault occurring, it can be automatic the detection system, and can send the warning indication of flicker; Only if remove the using electricity system fault fully, can not disappear otherwise report to the police.
The technical scheme that the present invention proposes is: a kind of earthed system abnormal failure flicker warning indicating device comprises: earth leakage protective device circuit A, earthed system abnormal failure flicker warning indicating circuit B; Earthed system abnormal failure flicker warning indicating circuit B comprises ground wire misconnection phase line functional circuit and or live wire/zero line backward error connection function circuit.
Ground wire misconnection phase line functional circuit with or live wire/zero line backward error connection function circuit; When ground wire PE misconnection phase line L; When perhaps abnormal failure appears in using electricity system; Ground wire misconnection phase line functional circuit can detect automatically, sends flickering vision warning or sound sensation warning or normal photopic vision warning or long time of alarm; When live wire and the wiring of zero line backward error, perhaps using electricity system appearance zero/fire intersects when supplying power unusually, and live wire/zero line backward error connection function circuit can detect automatically, sends flickering vision warning or sound sensation warning or normal photopic vision warning or long time of alarm; Comprising: current limiting capacitance 1, diode 2, current-limiting resistance 3, current-limiting resistance 4, discharge resistance 5, diac 6, light emitting diode 7, storage capacitor 8, diode 9.
Ground wire misconnection phase line functional circuit with or the connected mode of live wire/zero line backward error connection function circuit, an end of current limiting capacitance 1 is connected in input ground (PE-IN), the other end connects and the anode of diode 2 and the negative electrode of diode 9; The negative electrode of diode 2 is connected in an end of current-limiting resistance 3, and the other end is connected in an end of current-limiting resistance 4, an end of discharge resistance 5 and an end of storage capacitor 8; The other end of discharge resistance 5 is connected in diac 6 one ends; Diac 6 other ends are connected in the anode of light emitting diode 7; The negative electrode of light emitting diode 7 is connected on the zero line (N-IN) of the other end, input end of the other end, the discharge resistance 5 of anode, the storage capacitor 8 of diode 9;
Earthed system abnormal failure flicker warning indicating circuit comprises: the flickering vision indication, dodge ring audible indication, normal photopic vision indication, the normal audible indication of ringing.
Compared with prior art, significant effect:
Original warning indication technology, when short trouble appearred in earth system and phase line, it was can not warn prompting under the prerequisite that the contact of earth leakage protective device does not break off; And warning indication of the present invention is technological, exactly the indication no matter contact closure or disconnection all can be reported to the police simultaneously (that is to say that tube apparatus does not have not in use, as long as break down the indication of will reporting to the police).
Original warning indication technology, when live wire and zero line misconnection inverse time, and its indication of can not reporting to the police, the present invention indicates as long as just sending warning at once during zero/live wire wiring error.
Original warning indication technology, report to the police indication just lamp or the signal of Chang Liang can not have a kind of caution of clear vigilance to the people, and the present invention has adopted the concussion technology, and visual alarm or auditory cues that the indication of reporting to the police is glimmered bring a kind of clear-headed caution to the people.
