Abstract
The utility model relates to a single phase electricity filching detection comparison meter, which aims to solve the technical problem that how to discover electricity filching behavior of lawless person in time. The single phase electricity filching detection comparison meter comprises a shell and a metering module in the shell, wherein a zero line and a phase line respectively penetrate through the shell, a current transformer is sheathed on the phase line, and the zero line and the phase line are respectively provided with a voltage sampling terminal in an inserting way. The single phase electricity filching detection comparison meter is characterized by also comprising an intelligent module controller and an infrared signal transceiver module, the metering module is connected with the infrared signal transceiver module through the intelligent module controller, and the intelligent module controller and the infrared signal transceiver module get electricity from the voltage sampling terminals through a rectifying transformer circuit. The single phase electricity filching detection comparison meter provided by the utility model has the advantages that the structure is simple, the cost is low, the installation is convenient, the position is concealed and the meter is difficult to damage, and the electricity filching behavior can be discovered in time, therefore, the single phase electricity filching detection comparison meter is suitable for being used for single phase user power supply network.
Description
Technical field
The utility model relates to a kind of electric energy meter, and particularly a kind of single-phase stealing detects the deck watch.
Background technology
Along with cost of material such as electric coal climb up and up, thermal power plant and power supply enterprise based on fire coal can't bear the heavy load, be in loss or meagre profit operation state for a long time, unfavorable power industry development, and the stealing electricity phenomenon that happens occasionally more increases the weight of this adverse effect, according to the national grid data presentation, the annual economic loss that causes because of " stealing " in the whole nation reaches 10,000,000,000 yuan more than, the serious countries and regions of stealing, and stealing is lost up to 10%～30% of power industry gross profit.
But the lawless person of " stealing " is often very hidden, is difficult to they are screened from vast electricity consumer.How in time finding lawless person's stealing, is the problem that presses for solution.
The utility model content
The technical problems to be solved in the utility model is how in time to find lawless person's electricity filching behavior, provides a kind of single-phase stealing to detect the deck watch.
For solving the problems of the technologies described above, this single-phase stealing detects the deck watch, comprise shell and inner metering module thereof, zero line wherein, phase line is passed shell respectively, be with current transformer on the phase line, the coil two ends of this current transformer link to each other with the current signal input end of metering module, zero line, also be inserted with the voltage sample terminal on the phase line respectively, above-mentioned voltage sample terminal links to each other with the voltage signal input end of metering module, it is characterized in that: it also comprises intelligent object controller and infrared signal transceiver module, metering module links to each other with the infrared signal transceiver module by the intelligent object controller, and above-mentioned intelligent object controller and infrared signal transceiver module are all by transformer rectifier circuit power taking from the voltage sample terminal.
So design, during use, before this single-phase stealing detected deck watch and be installed in branch family ammeter, on the branch family line behind the power bus, when the person of checking meter is checked meter, hold the infra-red remote control fetch equipment of adapted, read deck watch's numerical value of same user, this numerical value is compared with corresponding user's branch family ammeter numerical value, if certain user's branch family ammeter power consumption numerical value and stealing detect the poor of deck watch's power consumption numerical value, detecting deck watch's power consumption numerical value with stealing compares, be no more than preset range (as 2%), then being judged as this user does not have stealing suspicion; Otherwise be judged as this user stealing suspicion is arranged; The emphasis inspection has the user's electric energy meter and the circuit of stealing suspicion, comprehensively judges whether to exist electricity filching behavior, can in time find, investigate and prosecute electricity filching behavior.
As optimization, described voltage sample terminal is non-return screw.So design is installed the back and is difficult for illegally being removed.
As optimization, described enclosure element encapsulates with insulating resin, the slit ultrasonic soldering of described housing exterior.So design is not easy destroyed.
The single-phase stealing of the utility model detect the deck watch have simple in structure, cost is low, easy for installation, be difficult for being destroyed by (artificial or nature), can in time find the advantage of electricity filching behavior, be suitable for single-phase user's supply network.
