Description
Technical field
The utility model relates to technical field of power systems, particularly a kind of device that is applied in low-voltage customer, electricity filching behavior be checked.
Background technology
Growing along with intelligent grid, the demand of the intelligent user terminal matched with it also increases day by day, intelligent electric meter is a kind of novel electric energy meter, be also the intelligent terminal of intelligent grid, be mainly used in low voltage electric network, except the function of measuring with traditional ammeter basic electricity amount, also there is pre paid functionality, without manual metering, the inconvenience of having avoided manual metering to bring to the user has solved the problem of difficult charge simultaneously.On this basis, intelligent electric meter also has hardware clock and complete communication interface for adapting to intelligent grid, and reliability and security all improve greatly, meet the requirement of energy-conserving and environment-protective.
Yet indivedual electricity consumers are for seeking undue profits, and electricity filching behavior remains incessant after repeated prohibition.Whether early stage anti-theft electricity technology mainly seal paint to the holding screw for fastening live wire, zero line on measuring apparatus, if the user has implemented electricity filching behavior, can seal to paint by judgement and destroyedly judged; But nature occurs and comes off in the impact that easily is subject to the natural causes such as environment, weather due to sealing, cause the erroneous judgement of electricity filching behavior disconnected, for causing misunderstanding between electric company and user, do not re-used at present, this just provides the stealing basis for the stealing user.Use at present more be also for comparatively dangerous stealing electricity method be before intelligent electric meter direct lead wire, the leading-out terminal of intelligent electric meter exchange zero line and live wire wiring position, revise the intelligent electric meter internal wiring or cut off the various methodologies such as outside line of ammeter, its purpose is to make electric current not pass through intelligent electric meter, reach the purpose of stealing, for power supply department brings greater loss.
The utility model content
The utility model technical issues that need to address are to provide a kind of intelligent electric meter that can carry out accurately judging to electricity filching behavior and look into electricity filching device, effectively prevent the generation of illegal stealing electricity phenomenon, for power supply department is reduced the loss.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows.
The low-voltage intelligent ammeter is looked into electricity filching device, comprise that described electroscope, the first clamp on amperemeter and the output terminal of the second clamp on amperemeter are connected display device by wire respectively for differentiating the electroscope whether wiring of intelligent electric meter live wire is correct and being respectively used to measure the first clamp on amperemeter and the second clamp on amperemeter that the intelligent electric meter leading-out terminal flows through live wire current value and neutral line current value; Described display device comprises casing, be provided with the first charactron for showing the live wire current value on the end cap of casing, for the second charactron of showing the neutral line current value and for showing the live wire pilot lamp of intelligent electric meter leading-out terminal live wire wiring state, described the first charactron is connected with the first clamp on amperemeter, the second charactron is connected with the second clamp on amperemeter, and the live wire pilot lamp is connected with electroscope.
Owing to having adopted technique scheme, the technical progress that the utility model is obtained is as follows.
The utility model is simple in structure, with low cost, safe reliability is high, be applied in low voltage electric network whether the user who uses intelligent electric meter is existed to being checked of electricity filching behavior, and can accurately judge whether electricity filching behavior occurs, in order to prevent in time, reduced the loss of power supply department.
The accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
Wherein: 1. the first clamp on amperemeter, 2. the second clamp on amperemeter, 3. electroscope, 4. the first charactron, 5. the second charactron, 6. live wire pilot lamp.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
A kind of low-voltage intelligent ammeter is looked into electricity filching device, as shown in Figure 1, comprises the first clamp on amperemeter 1, the second clamp on amperemeter 2, electroscope 3 and display device.Wherein: whether electroscope 3 is correct for differentiating the wiring of intelligent electric meter live wire, and the first clamp on amperemeter 1 flows through the current value of live wire for measuring the intelligent electric meter leading-out terminal, and the second clamp on amperemeter 2 flows through the current value of zero line for measuring the intelligent electric meter leading-out terminal.
Display device comprises casing, is provided with the first charactron 4, the second charactron 5 and live wire pilot lamp 6 on the end cap of casing.The first charactron 4 is connected with the first clamp on amperemeter 1, for showing the live wire current value; The second charactron 5 is connected with the second clamp on amperemeter 2, for showing the neutral line current value; Live wire pilot lamp 6 is connected with electroscope 3, for showing intelligent electric meter leading-out terminal live wire wiring state.
The utility model is mainly used in the inspection whether intelligent electric meter user in the 220V low voltage electric network exists electricity filching behavior, and its using method is as described below.
At first, electroscope is contacted with the second binding post with the first binding post of intelligent electric meter, check that whether the live wire wiring state is correct, if the live wire pilot lamp is lighted, show that wiring is correct; As the live wire pilot lamp does not work, mean that live wire and zero line connect instead, can tentatively judge that electricity filching behavior occurs.
Then, according to the testing result of above-mentioned steps, the first clamp on amperemeter and the second clamp on amperemeter are connected to respectively on live wire and zero line, carry out reading of live wire current value and neutral line current value; The first clamp on amperemeter and the second clamp on amperemeter detected current value is transferred to respectively the first charactron by wire and the second charactron is shown, and judge that whether the live wire current value is identical with the neutral line current value.
When live wire current value and neutral line current value numerical value differ larger, can show that the user is using other zero lines and carrying out stealing.When the live wire current value equates with neutral line current value numerical value, but the current value shown from intelligent electric meter can show that the user privately changes the intelligent electric meter internal circuit and carries out stealing when different.
