Abstract
The utility model relates to a three-phase electricity stealing detection comparing watch, which aims at solving the technical problem that the electricity stealing acts of law-breakers can be found in time. Therefore, the three-phase electricity stealing detection comparing watch comprises an outer housing and an internal metering module, wherein, three phase lines penetrate through the outer housing respectively; each phase line is sheathed with a current transformer respectively, and a voltage sampling terminal is inserted in each phase line respectively; and each current transformer and each voltage sampling terminal are connected with the metering module. The three-phase electricity stealing detection comparing watch also comprises an intelligent module controller and an infrared ray signal transceiver module, wherein, the metering module is connected with the infrared ray signal transceiver module through the intelligent module controller; and the intelligent module controller and the infrared ray signal transceiver module can get the electricity from the voltage sampling terminal through a rectifying transformation circuit. The three-phase electricity stealing detection comparing watch has the advantages of simple structure and low cost, is not easy to be damaged, can discover the electricity stealing acts in time, and is suitable for three-phase power supply network for users.
Description
Technical field
The utility model relates to a kind of three-phase stealing and 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 three-phase stealing to detect the deck watch.
For solving the problems of the technologies described above, the stealing of this three-phase detects the deck watch and comprises shell and inner metering module thereof, wherein the three-phase phase line is passed shell respectively, every phase line is with current transformer respectively, and be inserted with the voltage sample terminal respectively, above-mentioned current transformer, the voltage sample terminal links to each other with 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 the stealing of this three-phase detected the 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 and same user's branch family ammeter respective value is compared, 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 to be destroyed by (artificial or nature).
The stealing of the utility model three-phase detect the deck watch have simple in structure, cost is low, easy for installation, the position is hidden, is difficult for destroyedly, can in time find the advantage of electricity filching behavior to be suitable for three-phase user supply network.
Description of drawings
Below in conjunction with accompanying drawing the stealing of this three-phase being detected the deck watch is described further:
Fig. 1 is the structural representation that the stealing of this three-phase detects the deck watch.
Fig. 2 is that three-phase stealing shown in Figure 1 detects the scheme of installation of deck watch in power supply grid.
Among the figure: 1 for shell, 2 for metering module, A, B, C be the three-phase phase line, 3 for current transformer, 4 for the voltage sample terminal, 5 for the intelligent object controller, 6 for infrared signal transceiver module, 7 be branch family ammeter for the three-phase stealing detects deck watch, 8.
Embodiment
Embodiment one: as shown in Figure 1, the stealing of this three-phase detects the deck watch and comprises shell 1 and inner metering module 2 thereof, three-phase phase line A wherein, B, C passes shell 1 respectively, every phase line is with current transformer 3 respectively, and be inserted with voltage sample terminal 4 respectively, above-mentioned current transformer 3, voltage sample terminal 4 links to each other with metering module 2, it is characterized in that: it also comprises intelligent object controller 5 and infrared signal transceiver module 6, metering module 2 links to each other with infrared signal transceiver module 6 by intelligent object controller 5, and above-mentioned intelligent object controller 5 and infrared signal transceiver module 6 are all by transformer rectifier circuit power taking from the voltage sample terminal 4.Described voltage sample terminal 4 is non-return screw.Described shell 1 inner member encapsulates with insulating resin, described shell 1 outside slit ultrasonic soldering.
The stealing of this three-phase detects the scheme of installation of deck watch in power supply grid referring to Fig. 2, slightly.
