Description
After the utility model relates to covil construction electric wiring work progress and completion; whether phase line (L) zero line (N) of indoor consumer and " line preface " between the protective ground line (E) and indoor electric leakage equipment (being electric leakage protector) are installed correctly, and action message and the device that detects.
Whether covil construction are electric adheres to specification for " the line preface " of line layout at line construction with after installing, and often feels simply helpless, or employing simple tools, as detecting with electroscope, but electroscope can only be judged " phase line " (being commonly called as live wire) under the indoor power supply situation.And it is still powerless for zero line and protective ground line.Indoor socket generally provides power supply to household electrical appliance, for example: washing machine, refrigerator, for safe in utilization, the single-phase three-terminal polarized plus plug of more employing.Wherein indicate directly communicating of E symbol with the electrical appliance shell.Thereby modern covil construction also just adopt relative measures in design, increase the protective ground line, and socket also adopts single-phase three-pole.As mentioned above, electroscope can only be judged " phase line ", and can't judge zero line and ground protection line.Even use universal meter at the scene; also can only judge " phase line " in three pole sockets; concrete operations are with exchanging the 250V shelves; measure three utmost points of socket respectively; one extremely when in addition the two poles of the earth have the voltage indication respectively (being generally 220V) arranged, then can judge this very " phase line ", but the two poles of the earth in addition; how to distinguish who be zero line (N) who be protective ground line (E)? and this troublesome poeration, it is quick to be not so good as electroscope.Moreover the working-yard is in a mess, and fragile universal meter adds and carries inconvenience, and is on-the-spot seldom with the such instrument of universal meter.Stagger the time but work as the mutual dress of zero line (N) and ground protection line (E), will pass through socket, the zero line in the feed circuit has been received household appliances shell.If it is disconnected that the insurance of power supply zero line is touched, " " will get back on " zero line " by electrical appliance (as bulb)---promptly scurry the shell of household electrical appliances, personal safety is caused very big threat.Obviously adorn mutually with " ground protection line " when " phase line " and stagger the time, more can cause harm life! Therefore quality testing department is to single-phase three pole socket internal wirings, and whether reliable, correct requirement be very tight, but suffer from the method that does not have a kind of simple possible.In addition, the auroral poles that the electroscope neon bulb sends is faint, and with the growth of operating period more and more a little less than.
Modern covil construction are electric; in order to take precautions against the harm of home electric electric leakage to life; except that adopting earthing of casing protection; relevant management of power use department (as the Beijing area) expressly provides; newly-built covil construction want each household that electric leakage protector is installed without exception, in case purpose is circuit or household electrical appliance leaks electricity, when the someone gets an electric shock again, when leakage current during greater than 30NA; electric leakage protector just should move, and blocks power supply.Past; detection to the leak source protector that installed; want petty powerless; want petty other technician to adopt the method for bulb and temporary ground wire; between the phase line of socket and ground wire, test; the electric leakage protector switch motion; circuit is described; the electric leakage protector wiring is error-free; can't do you but in case when leakage switch occurring and being failure to actuate, judge that then the protective ground line has broken? do (can't determine that because of test pencil universal meter is also powerless) still leakage switch wiring have problem? or have both at the same time? this method is not only unreliable; and be absolutely unsafe; careless slightly in the test, promptly can get an electric shock or the burn-out test utensil, it is dangerous therefore doing this test.
The purpose of this utility model provides a kind of device that can judge installation of architectural electricity circuit and electric leakage protector wiring correctness at the scene, and it can accurately demonstrate all kinds of mistakes that exist in the circuit installation significantly.And structure is small and exquisite, and is easy to carry, not fragile.
The purpose of this utility model is to realize like this, one have two or the box of three-terminal polarized plus plug bar in, two light emitting diodes are housed on its panel, light emitting diode is contacted mutually with dropping resistor and commutation diode in the box, a light emitting diode, show phase line and zero line relation, normally indicate as power supply.The another light emitting diode shows the relation between phase line and the ground protection line, does the whether normal indication of protection ground wire.Miniature microswitch is housed on the panel in addition, switch links to each other with anthropomorphic dummy's bulk resistor, alarm buzzer respectively, press simulation human electric shock's microswitch, the electric current that a 30NA-50NA is arranged is through anthropomorphic dummy's bulk resistor, between phase line and ground wire, flow, the electric leakage protector switch is answered quick acting, blocks power supply, and two light emitting diodes all go out.Undesired as circuit, leakage switch is failure to actuate, and this moment, hummer communicated with this microswitch circuit, will send the sound, told the operator; Leakage switch or its interlock circuit have problem, and when leakage switch is failure to actuate, the sound does not take place again hummer simultaneously, illustrates that detector is bad, should change another and detect, so this device also has self-checking function!
The utility model is (or finish as quality testing the part) after the covil construction electrical construction is finished; (L) " zero line " (N) to " phase line "; whether protective ground line (E) and leakage switch wiring be reliable; only need the attaching plug of this detector as household electrical appliance inserted in the indoor respective socket; just can show and test button from light, judge various wiring errors (specifically seeing attached list).Solved with electroscope and can not judge all Problem-Error of indoor electric in installing.And just can detect (electric leakage protector is contained in the each household ammeter box, generally outdoors) at the scene to electric leakage protector, and use and observe easily, need not go to and go outdoors to see whether leakage switch moves.This detector is owing to be to use diode displaying, and indication is bright, joins in the use and different colors, and is then more directly perceived, comes into plain view, and has overcome electroscope and has adopted the neon bulb of induction type luminous, flashes, and shows unconspicuous defective under the high light line.
The utility model concrete structure provides with following embodiment and accompanying drawing thereof.And be described with reference to the accompanying drawings its principle of work and mode.
Figure (1) is a profile of the present utility model.Profile is by shell (6) light emitting diode, and (1), (3) and miniature microswitch (4) and three-terminal polarized plus plug bar (5) are formed.Hummer (2) is equipped with in the inside of this detector, 4 of resistance, 3 of diodes.During use, this detector as common single-phase three-pole attaching plug, is inserted in indoor single-phase three pole sockets, this moment three-terminal polarized plus plug bar (5), by (5
