Abstract
The utility model relates to an electric larceny preventing device for a fire line and an earth lead, comprising an electric meter, a live wire, a zero line and a user terminal, wherein the electric meter comprises a live wire lead-in terminal, a zero line lead-in terminal, a live wire lead-out terminal and a zero line lead-out terminal, the zero line is connected with the zero line lead-in terminal, and the live wire lead-out terminal is connected with the user terminal. The device further comprises an electric larceny preventing module and a grounding switch, wherein the electric larceny preventing module comprises an electric larceny preventing switch and a detecting line, the electric larceny preventing switch is connected between the live wire and the live wire lead-in terminal, the detecting line are respectively connected with the zero line and the zero line lead-out terminal, and the zero line lead-out terminal and the grounding switch are connected. When the grounding switch is switched off, the electric larceny preventing switch is switched off, and the electric larceny preventing switch is switched on in other cases. Compared with the prior art, the wire connection is automatically off when the user has the behavior of the a fire line and an earth lead; the device has an automatic recovery function, and if the user stops electric larceny, the device can automatically recover power supply to the user.
Description
Technical field
The utility model relates to a kind of anti-electricity-theft device that is used for a line one ground, especially relates to a kind of anti-electricity-theft device that is used for a line one ground.
Background technology
Along with the large scale investment of electronic type resident ammeter is used, also expedited the emergence of novel stealing mode.With respect to the stealing mode of traditional short circuit live wire, what rising at present is the electricity filching behavior on a line one ground.The stealing mode on one line, one ground refers to the live wire that sign to use in the electrical network and powers, and cuts off the ground wire (by pulling out, block mode such as zero line) of ammeter, and uses the earth to power as the zero line of indoor distribution line.
The stealing mode on one line, one ground has very strong fascination.On daytime, electricity filching person is with indoor grounding switch closure, and when the meter reading personnel arrived, ammeter was working properly, can normally copy reading data, and to more indoor grounding switch being opened at dusk, ammeter can't normal billing after losing ground wire.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of anti-electricity-theft device that is used for a line one ground for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of anti-electricity-theft device that is used for a line one ground, comprise ammeter, live wire, zero line, user terminal, described ammeter is provided with the live wire end of incoming cables, the zero line end of incoming cables, the live wire leading-out terminal, the zero line leading-out terminal, described zero line is connected with the zero line end of incoming cables, described live wire leading-out terminal is connected with user terminal, it is characterized in that, also comprise anti-electricity-theft module, grounding switch, this anti-electricity-theft module comprises anti-electricity-theft switch, detection line, described anti-electricity-theft switch is connected between live wire and the line end of incoming cables, described detection line respectively with zero line, the zero line leading-out terminal connects, described zero line leading-out terminal is connected with grounding switch, disconnect when detection line detects zero line and zero line end of incoming cables, and grounding switch is when disconnecting, anti-electricity-theft switch disconnects, anti-electricity-theft switch closure during other situations.
Compared with prior art, the utlity model has that the automatic cutout electric wire connects when having guaranteed when the normal electricity consumption of user that user's power supply, user have a line one ground electricity filching behavior; Have self-recovering function, if the user stops electricity filching behavior, equipment can recover the power supply to the user automatically, need not artificial participation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of anti-electricity-theft device that is used for a line one ground, comprise ammeter 3, live wire 1, zero line 2, user terminal 6, described ammeter 3 is provided with the live wire end of incoming cables, the zero line end of incoming cables, the live wire leading-out terminal, the zero line leading-out terminal, described zero line 2 is connected with the zero line end of incoming cables, described live wire leading-out terminal is connected with user terminal 6, also comprise anti-electricity-theft module 4, grounding switch 5, this anti-electricity-theft module 4 comprises anti-electricity-theft switch 41, detection line 42, described anti-electricity-theft switch 41 is connected between live wire 1 and the line end of incoming cables, described detection line 42 respectively with zero line 2, the zero line leading-out terminal connects, described zero line leading-out terminal is connected with grounding switch 5, disconnect with the zero line end of incoming cables when detection line 42 detects zero line 2, and grounding switch 5 is when disconnecting, anti-electricity-theft switch 41 disconnects anti-electricity-theft switch 41 closures during other situations.
