Abstract
The utility model discloses an electric three-phase power-supply socket with displaying ground electrode. The utility model belongs to the innovate technology of the electric three-phase power-supply socket. The socket is composed of a base board, a connection pin and an upper cover plate. The socket is characterized in that an electric displayer is arranged between the ground connection pin and the installation wall. The electric displayer is composed of connecting conductors inserted in the wall, a resistor and a display lamp or a diode. The utility model has the advantages of simple structure, safety and effective display of electrification phenomenon of ground electrode of the socket.
Description
Technical field
The utility model relates to a kind of three-phase power socket that shows ground wire electrification, belongs to the improvement technology of three-phase power socket.
Background technology
The ground wire of existing three-phase power socket, the fail safe that generally has use, but in a single day earth wire failure or live wire and ground wire misconnection take place, but equal spot tape electrical phenomena, thereby can cause electrical equipment charged, this brings dangerous can for the electrical equipment user.
Summary of the invention
The purpose of this utility model is to provide a kind of three-phase power socket that shows ground wire electrification, can discharge fault thereby this socket can show the socket ground wire electrification, guarantees Electrical Safety.
The utility model is realized by following proposal.The three-phase power socket that comprises the demonstration ground wire electrification that constitutes by base plate, leg and upper cover plate, it is characterized in that, with between the walls is installed electrification display is set in the earth polar leg, this electrification display constitutes by inserting body of wall bonding conductor and resistor and display lamp or diode.
Advantage of the present utility model is, and is simple in structure, can show the electrification phenomenon of socket ground wire effectively, and prompting the electric consumer fix a breakdown, and guarantees Electrical Safety.
Description of drawings
Fig. 1 is two three-phase power socket structural representations of the present utility model.
1 is upper cover plate among the figure, and 2 is base plate, and 3 is resistor, and 4 is display lamp, and 5 for inserting conductor within the walls.
Embodiment
With accompanying drawing 1 is embodiment, illustrates that the utility model shows the ground wire electrification process.On the earth polar of two three-phase power sockets, by lead series resistor device 3 and display lamp 4, connect to insert conductor 5 in the body of wall by lead then, if this socket earth polar is because of fiery ground wire misconnection, or because the ground connection effect is bad, cause ground wire electrification, this moment, the socket ground wire was a high potential, and then electric current constitutes a loop, the bright explanation ground wire electrification of display lamp through resistor 3, display lamp 4 to body of wall inner wire 5, to in time investigate fault, guarantee the safe in utilization of power supply.
Claims (1)
1, a kind of three-phase power socket that shows ground wire electrification, comprise by base plate, leg and upper cover plate and constituting, it is characterized in that: with between the walls is installed electrification display is set in the earth polar leg, this electrification display constitutes by inserting body of wall bonding conductor and resistor and display lamp or diode.
