An alarm indication device for detecting the abnormal voltage of the earthed system; the device comprises an all-round electricity leakage protector which is equipped with the examining inductor for the electrified earth wire, the earth wire contact, the phase line contact, the null line contact. The alarm indication circuit is disposed between the fixed contact and the moving contact of the earth wire contact. Such alarm indication circuit is made via the series connection of the neon light, the resistance and the connecting lead.
Description
Technical field
The utility model relates to the safety technique for using electricity field, particularly a kind of device that can send the indication of reporting to the police when abnormal voltage appears in earthed system.
Background technology
Earthed system is a protection system the most basic in the safety utilization of electric power; so-called earthed system; be 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 allow it keep no-voltage, to ensure user's personal safety with palp conductiving metal part is connected with earthed system.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.The Chinese invention patent communique discloses a kind of all-purpose leakage protection plug; its patent publication No. is CN1350352A; this all-purpose leakage protection plug is a kind of comprehensive Electrical Safety protector; it is except having creepage protection function; the more important thing is that it is when earthed system is unusual; a pair of earth polar contact that also can be by its inside is the earthed system disjunction, thereby allows in the palp metallic conduction parts of electrical equipment and the socket charged hole, earth polar separate, and guarantees user's safety.In case when the all-powerful leakage protection device moves because abnormal voltage is arranged earthed system,, can not send clear and definite warning indication though it can the disengagement failure power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can send the indication of reporting to the police when abnormal voltage appears in earthed system; this warning indicating device is contained on the all-powerful leakage protection device and is mated work; in case when cutting off the power supply with electric fault; it can detect earthed system immediately automatically; when earthed system band abnormal voltage, will send the indication of reporting to the police; unless all-powerful leakage protection device and power supply are broken away from fully, otherwise this warning can not disappear.
The technical solution that the utility model proposed is such: a kind of device that can send the indication of reporting to the police when abnormal voltage appears in earthed system; comprise the all-powerful leakage protection device; be provided with ground wire electrified detection inductor and ground wire contact, phase line contact, zero line contact in this protector, deciding to be connected with between contact and the moving contact by neon lamp, resistance and connect the warning indicating circuit that lead is in series at the ground wire contact.Neon lamp in this warning indicating circuit is installed on the all-powerful leakage protection device shell.
When electricity consumption just often, the ground wire contact closure, warning indicating circuit two ends do not have voltage, neon lamp can be not shinny.When electricity consumption is broken down, the action of all-powerful leakage protection device, the disjunction of ground wire contact, earthed system just becomes pick-up unit automatically, in case earthed system band abnormal voltage, neon lamp just sends the indication of reporting to the police.Because the all-powerful leakage protection device is irreducible when ground wire electrification; this can not be closed to the ground wire contact; therefore the indication of reporting to the police can not disappear, unless the all-powerful leakage protection device separated fully with power supply or with after the grounding system fault eliminating, just pilot lamp can extinguish.
Compared with prior art, the beneficial effect that the utility model produced is:
1, the utility model is the device that a kind of earthed system that cooperates with all-powerful leakage protection device (plug) can be sent the indication of reporting to the police when abnormal voltage occurring; in using electric process; in case occur with electric fault and in the outage of all-powerful leakage protection device; can detect earthed system immediately automatically; when abnormal voltage appears in earthed system, can send alerting signal, allow the user can make right judgement immediately.Described alerting signal can be a wigwag, also can be acoustical signal.
Can send the device of the indication of reporting to the police when 2, abnormal voltage appears in the earthed system that cooperates with all-powerful leakage protection device (plug); has only the all-powerful leakage protection device action that ought be complementary with it; this device is just in running order; also have only when the band abnormal voltage of ground wire contact two ends this device just can send the indication of reporting to the police; this device and power supply mutually, zero irrelevant extremely fully; whether it is a detection system independently, be not subjected to phase, zero utmost point to have film to ring.
The device that can send the indication of reporting to the police when 3, abnormal voltage occurring owing to this earthed system is the pick-up unit that is added in purely on the ground wire, therefore it does not influence phase in the power supply, or zero, between industrial frequency withstand voltage and insulating property, can not constitute any influence to feed circuit.
The utility model can be widely used in and do the safety utilization of electric power protection in various household electrical appliance, the daily-use electrical appliance.
Description of drawings
Fig. 1 is the device electrical schematic diagram that can send the indication of reporting to the police when abnormal voltage appears in earthed system that is used for cooperating with all-purpose leakage protection plug among embodiment of the utility model.
Embodiment
By following embodiment the utility model is described in further detail.
Referring to shown in Figure 1; a kind of device that can send the indication of reporting to the police when abnormal voltage appears in earthed system mainly is made up of neon lamp 1, resistance 2, lead 3,8; after neon lamp 1, resistance 2, lead 3,8 series connection; lead 3,8 is connected on the right moving contact 4 of all-purpose leakage protection plug 6 interior ground wire contacts respectively and decides on the contact 5, constitutes the warning indicating circuit.When ground wire 7 has electric current to flow through suddenly; all-purpose leakage protection plug 6 actions; fixed, moving contact 5,4 automatic disjunctions; thereby form a complete electronic circuit: contact 5 is decided in the earth polar, and---------resistance 2---lead 3---earth polar moving contact 4, this circuit directly detects the state of earthed system to neon lamp 1 to lead 8.In case earthed system band abnormal voltage, it is charged that contact 5 is decided in the earth polar, just abnormal voltage is added in the neon lamp 1 and resistance 2 two ends of having connected, and neon lamp 1 just sends warning light.If earthed system does not normally then have abnormal voltage to occur; neon lamp 1 just can not be luminous; thereby can judge with electric fault realizingly or belong to other that class faults; in case light warning occurs; have only all-purpose leakage protection plug 6 and power supply are broken away from fully; perhaps the earth polar recovers normal, and neon lamp 1 just can extinguish.
