Description
Technical field
The invention belongs to electrician and electronic technology field, is about a kind of three supply socket fault detectors.
Background technology
Three supply sockets at home or newly-built building all has very large consumption, no matter three supply sockets are the detections after a large amount of installation the on engineering, or the maintenance after breaking down, for the electrician, it is all very large workload, and the duplication of labour had a large capacity and a wide range, under-enumeration occurring or detects mistake happens occasionally.In order well to solve this practical challenges; what three supply socket fault detectors of the present invention can become very loaded down with trivial details scissors and paste is very convenient light; these three supply socket fault detectors are for checking live wire, ground wire, the zero line in single-phase three supply sockets; whether correctly reach the earth leakage protection test; especially more show unique function in the building final inspection, and detected state and testing result can eye-catchingly show.The present invention is also the ideal tools of electricians' check processing uniline problem.
Below describe three supply socket fault detectors of the present invention related correlation technique in implementation process in detail.
Summary of the invention
Goal of the invention and beneficial effect: what three supply socket fault detectors of the present invention can become very loaded down with trivial details scissors and paste is very convenient light; these three supply socket fault detectors are for checking live wire, ground wire, the zero line in single-phase three supply sockets; whether correctly reach the earth leakage protection test; especially more show unique function in the building final inspection, and detected state and testing result can eye-catchingly show.The present invention is also the ideal tools of electricians' check processing uniline problem.
The circuit working principle: three supply sockets adopt the national standard mode of connections, that is: zero line N is on a left side, live wire L(phase line) on the right side, superincumbent is protection ground wire E.Used 3 silicon rectifier diodes in circuit, this is because the reverse withstand voltage 220V that far do not reach of LED is not reversed voltage breakdown so access silicon rectifier diode 1N4007 in order to the PN junction of protecting LED.
Three supply socket CZ insert three supply socket fault detectors in three supply sockets after connecting 220V AC power and protection ground wire E, and light emitting diode is lighted with the logical relation of extinguishing and is:
1. if three supply socket live wire L, zero line N and protection ground wire E wiring are normal, red light emitting diodes LED1 goes out, and yellow light-emitting diode LED2 is bright, and green LED LED3 is bright;
2. if three supply socket live wire L and zero line N have connect instead, red light emitting diodes LED1 is bright, and yellow LED2 is bright, and green LED LED3 goes out;
3. if live wire and protection ground wire E have connect instead, red light emitting diodes LED1 is bright, and yellow led 2 goes out, and green LED LED3 is bright;
4. if lack zero line N or zero line N has broken, red light emitting diodes LED1 goes out, and yellow light-emitting diode LED2 goes out, and green LED LED3 is bright;
5. if lack protection ground wire E or protect ground wire E to break, red light emitting diodes LED1 goes out, and yellow light-emitting diode LED2 is bright, and green LED LED3 goes out;
6. if lack live wire L or live wire L has broken, red light emitting diodes LED1 goes out, and yellow light-emitting diode LED2 goes out, and green LED LED3 goes out;
7. occurring that " lacking zero line N and live wire L, zero line N wrong " or " lacking protection ground wire E and live wire L and protection ground wire E wrong " is while having one of these two kinds of mistakes; because the polarity of diode is consistent; 3 LEDs just in time to LED, provide current path, so all can be lighted.But both of these case is extremely rare.
