Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, the safety electricity experience device circuit includes a power supply, a terminal block D1, a safety unit, an alarm unit, at least one first relay K1, a second relay K2, and a third relay K3. The first relay K1 is provided with a first normally open contact and a second normally open contact, the second relay K2 is provided with a third normally open contact, and the third relay K3 is provided with a normally closed contact. The terminal block D1 includes several wiring sets, which include two mutually insulated terminals.
The first relay K1 is connected with the power supply after being connected with the wiring group in series, and the second relay K2 is connected with the power supply after being connected with the wiring group and the first normally open contact in series in sequence. The second normally open contact, the third normally open contact and the safety unit are connected in series and then connected with the power supply, the third relay K3 is connected in parallel and connected with the safety unit in parallel, and the normally closed contact is connected with the power supply after being connected with the alarm unit in series.
The user performs a wiring operation on the terminal of the terminal block D1 through the connection wire. When the user correctly worked that works a telephone switchboard, normally work behind first relay K1 lug connection power promptly, then first normally open contact and second normally open contact are closed, then second relay K2 is connected the back through the first normally open contact of closed and power and normally works, then third normally open contact is closed. The safety unit and the third relay K3 work normally after being connected with the power supply through the closed second normally open contact and the closed third normally open contact, then the normally closed contact is opened, and the alarm unit is disconnected with the power supply after the normally closed contact is opened, so that the wiring operation of a user is correct. When the user performs wrong wiring operation, namely the first relay K1 is connected with the power supply through the first normally open contact, the second relay K2 does not work normally at the moment, and then the first normally open contact and the second normally open contact are still opened. The second relay K2 works normally after being directly connected with the power supply, and then the third normally open contact is closed. The safety unit and the third relay K3 are disconnected with the power supply due to the opening of the second normally open contact, and the alarm unit is connected with the power supply through the normally closed contact to give an alarm, which indicates that the wiring operation of the user is wrong.
