Abstract
The utility model relates to a device for testing single phase socket connection and electric leakage of switches, which is composed of an outer shell 1, a shell body 2, a plug 3 and a test display circuit 4. The utility model is characterized in that resistors, diodes and luminous tubes are connected in series among an earth line, a zero line and a phase line of the test display circuit; in addition, a circuit connected in series by bleeder resistors R< K > of the switches is connected in parallel between the phase line and the earth line. The product can once simultaneously test whether the connection of the earth line, the zero line and the phase line is right, wrong or leaking joint, and can test whether an electric leakage switch is good or bad.
Description
Single-phase socket wiring and leakage switch verifier (hereinafter to be referred as verifier) are made up of shell, housing, pin, checking circuit.
Strict regulation has been made to the safe handling of electrical equipment by country, as: the position of the ground wire that socket connects, zero line, phase line can not misplace, miss.Now, whether people misplace, miss with the wiring of " multimeter " check socket, all will check every wiring, bring the very big inconvenience and the length that takes time to work, and the circuit of hiding more very.
The purpose of the utility model verifier is exactly to design a kind of simple in structure, new product of improving check speed.
Whether the scheme of verifier is a kind of simple inspection display circuit of design, can once check the position of ground wire, zero line, phase line of socket correct simultaneously, misconnection, miss.The quality that the attached circuit check leakage switch that can produce little electric current is arranged simultaneously.
The feature of the utility model verifier is that verifier has the check display circuit, and ground wire, zero line and the phase line of check display circuit have been gone here and there resistance, diode and luminotron each other, and luminotron is fixed on the shell.In addition, be parallel with the circuit of switch and bleeder resistor series connection between phase line and ground wire, switch is fixed on the shell.
The utility model is simple in structure, and operation is reliable, and check is quick, practicality, and low price is electric consumer's good assistant.
Now illustrate verifier with an embodiment.
Fig. 1 is the three-dimensional string figure of verifier;
Fig. 2 is the checker circuit schematic diagram.
Verifier (Fig. 1) is made up of shell 1, housing 2, pin 3, check display circuit 4.Check display circuit (Fig. 2): resistance R
1-3, R
kBe bleeder resistor, D
1-3Be unilateral diode, LED
1-3Be luminotron, three luminotrons are in line and are fixed on case surface (Fig. 1,2), and K is a pushbutton switch, it is fixed on case surface, its principle of work: when plug is inserted people's supply socket, if the socket wiring is correct, owing between phase line and zero line, phase line and the ground wire 220 volts of voltages are arranged, so LED
1, LED
2Bright, and be equipotential between zero line and the ground wire, so LED
3Do not work.
When socket lacks the ground wire connection, to have only between phase line and the zero line voltage is arranged, this moment is LED only
2Bright, LED
1, LED
3Because of no-voltage does not work.So analogize, when there was voltage at the luminotron two ends, luminotron was bright, and during the no-voltage of luminotron two ends, luminotron does not work, by the different demonstrations combination of three luminotrons, just can judge each wiring position whether misconnection, miss.
The check leakage switch is button switch K and the bleeder resistor R between phase line and ground wire
kBetween carry out.If the circuit wiring is correct, when pressing the button K, because R
kThe earial drainage effect, have the earth leakage circuit-breaker of being a bit larger tham action current to flow through between relatively, leakage switch should trip at once, otherwise leakage switch has fault, need fix a breakdown, and could use after fixing again.
The verifier course of work is: verifier inserts socket and observes three luminous combinations of luminotron, just can differentiate the wiring situation.(seeing the check status list)
The check status list
Annotate: the left, center, right luminotron shows ground wire, zero line and the phase line that should connect respectively
| Luminotron wiring situation | Show | |||
| A left side | In | Right | ||
| Wiring is correct | Bright | Bright | ||
| No ground wire | Bright | |||
| No phase line | ||||
| No zero line | Bright | |||
| Phase line and zero line wrong | Bright | |||
| Phase line and ground wire wrong | Bright | |||
| Phase line and ground wire wrong, and do not have ground wire | Bright | Bright | ||
This product is safe and reliable, clear display, can check three wiring to have or not mistakes and omissions simultaneously.Not that the professional all can use.
Claims (2)
1, a kind of single-phase socket wiring and leakage switch verifier, form by shell, housing, pin, checking circuit, it is characterized in that having the check display circuit, it is installed in shell and the housing, and ground wire, zero line and the phase line of check display circuit have been gone here and there resistance each other.Diode and luminotron, luminotron is fixed on the shell.
2. single-phase socket wiring according to claim 1 and leakage switch verifier is characterized in that being parallel with between the phase line of described check display circuit and ground wire the circuit of switch and bleeder resistor series connection.
