Description
Technical Field
The utility model relates to an intelligent electric meter field, especially a single-phase intelligent electric meter's anti-electricity-theft protection device.
Background
The supply of electric energy is not available in all walks of life in the present society. In practical situations, not all power consumers have good quality, and some power consumers change the wiring of the electric meter for private use, so that the purpose of electricity stealing is achieved. In order to ensure that the electricity is not interrupted when the electricity meter is replaced (the influence of sudden power failure on the electricity consumption of a user is prevented), the existing one-way intelligent electricity meter is provided with a meter head and a wiring pile mechanism part (the wiring pile mechanism is arranged on a bottom plate, the wiring pile mechanism is not replaced when the electricity meter is replaced, only the meter head is replaced, the meter head is positioned at the front end of the bottom plate after being replaced, the wiring pile mechanism is connected with the meter head and positioned at the rear end of the bottom plate after being spliced, the meter head is connected with the wiring pile mechanism through a plug-in part, when the meter head needs to be replaced, a worker firstly prizes an upper cover (plastic material) of the wiring pile mechanism, then inserts an uninterrupted inserting plate with four upright posts into four metal inserting holes at the upper end of the wiring pile mechanism (the four metal inserting holes are respectively communicated with a phase wire, a user phase wire, a phase wire and a zero wire and the user zero wire), and further under the action of the internal mechanism of the wiring pile mechanism, the plug connector of the gauge outfit is separated from the wiring pile mechanism. Because the two stands of left end in four stands of uninterrupted power supply picture peg inside electric property intercommunication, two stands of right-hand member communicate with each other (the uninterrupted power supply picture peg outside is insulating material makes things convenient for staff's operation and does not electrocute), be equivalent to the short circuit inlet wire phase line and user's phase line, between inlet wire zero line and the user zero line, the ammeter is by the bypass, before staff combines new ammeter gauge outfit plug connector and wiring stake mechanism like this, has guaranteed user's normal uninterrupted power consumption.
In order to prevent electricity stealing of the existing intelligent electric meter, an electricity stealing prevention mechanism is arranged at the upper end of a wiring pile of a meter head (a movable cover at the upper end of the wiring pile of the meter head is fixed by a screw rod, then an annular metal wire penetrates into an opening between the screw rod and the upper end of the movable cover, and two joints of the annular metal wire are fixed by lead sealing, so that the purpose of electricity stealing prevention is achieved). Although above-mentioned mode can prevent to steal the electric person and open the movable cover of gauge outfit, can't prevent to steal the electric person and pry open the upper cover of wiring stake mechanism with the instrument, and then four metal inserted holes of short circuit wiring stake mechanism reach the purpose of stealing the electricity (use two wire short circuit inlet wire phase lines and user phase line respectively, between inlet wire zero line and the user zero line), therefore current intelligent electric meter anti-electricity-theft mode still has great problem.
