Abstract
The utility model relates to a detector for the single-phase triplex wire socket, comprising a socket casing and three inserting pieces, which is characterized in that the live wire inserting piece is connected in parallel with two resistances and a button switch, one of the resistances is connected with the anode of a LED, the cathode of the LED is connected with the neutral line inserting piece; the button switch is in series connected with one resistance, and connected with the other end of the other resistance and the anode of the LED in parallel; the cathode o f the LED is connected with the ground line inserting piece. The utility model has an advantage that the detector can detect the reverse connection between the neutral line and the ground line.
Description
Technical field
The utility model relates to a kind of detecting device, particularly a kind of single-phase three-wire socket detection device.
Background technology
The general idea of often installing owing to the workmen in the single-phase three-wire socket that uses in family decoratees causes zero line and ground wire wrong at present, causes the accident of electricity consumption easily.
Summary of the invention
The purpose of this utility model is to solve the general idea of often installing owing to the workmen in the single-phase three-wire socket that uses in family's decoration in the prior art to cause zero line and ground wire wrong, causes the problem of the accident of electricity consumption easily.Technical solutions of the utility model design single-phase three-wire socket detection device, comprise Socket casing, three inserted sheets, it is characterized in that: the phase line inserted sheet also connects two resistance and a pushbutton switch, connecting resistance connects a light emitting diode anode in the lump, light emitting diode negative terminal connecting to neutral line inserted sheet, pushbutton switch is connected in series the other end of a resistance and another and connecting resistance and the anode of light emitting diode joins light emitting diode negativing ending grounding line inserted sheet.The utility model has the advantages that and to utilize single-phase three-wire socket detection device to detect whether wrong of ground wire and zero line easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Phase line inserted sheet 1 and connect two resistance 2,3 and a pushbutton switch 4 among the embodiment figure, connecting resistance 2 connects a light emitting diode 5 anodes in the lump, light emitting diode 5 negative terminal connecting to neutral line inserted sheets 6, pushbutton switch 4 serial connection one resistance 7 joins light emitting diode 8 negativing ending grounding line inserted sheets 9 with another and the other end of connecting resistance 3 and the anode of light emitting diode 8.When detecting device inserts socket; correct as wiring; then light emitting diode 5,8 is luminous; as zero line and ground wire wrong; then the earth leakage protective device on the circuit trips, and not working as light emitting diode 5 illustrates that zero line has problem, and light emitting diode 8 does not work and illustrates that ground wire has problem; or phase line and zero line connect instead, and pushbutton switch 4 is pressed and can be detected whether operate as normal tripping operation of earth leakage protective device.
