Abstract

The utility model discloses a wide working voltage multi-rate electric-energy meter for preventing illegal use, which belongs to an electric energy measuring device and is composed of a meter bottom shell, a meter cover, a data plate, a terminal holder, an end cover, a printed plate and a display. The printed plate and the display are mounted in the meter bottom shell, and the data plate is clamped in the meter cover. The meter cover is capped on the meter bottom shell, and the terminal holder is mounted in the lower frame of the meter bottom shell. The end cover is capped on the terminal holder, magnetic force contactors are arranged on the optional positions of the printed plate and the terminal holder, and the corresponded data plate and the terminal holder are mounted with magnetic elements. The magnetic elements are cooperated with the magnetic force contactors, producing high level/low level signals which are sent to the I/O interface of s single chip machine, and a CPU recorder is started to record the frequency and the time of an electricity thief secretly opening the end cover or the meter cover. The record can be taken as a reference for punishing the electricity thief, being able to timely discover and prevent electric larceny and punish the electricity thief according to law to reduce the loss of electric larceny of China.

Description

The anti-electricity-theft multi-rate electric energy meter of wide operating voltage

Affiliated technical field

The utility model relates to a kind of electric energy metering device, the anti-electricity-theft many rates electric energy metering device of particularly a kind of wide operating voltage.

Background technology

Present used electric energy meter, its anti-electricity-theft main method all is to adopt two Kong Houyong lead sealings of passing on it with the lead sealing line between terminal base and end cap to seal, not opening lead sealing just can not pull down end cap or table lid, thereby realize anti-electricity-theft, to seal the anti-electricity-theft weak point of method be lead sealing by electricity filching person dismantles and can copy lead sealing again after reaching the stealing purpose with lead sealing, can not effectively prevent stealing.

Summary of the invention:

The purpose of this utility model is the weak point that overcomes at present used electrical energy meter anti-theft electricity method, as long as being provided, a kind of electricity filching person opens end cap or table lid, recorder cpu in the ammeter is just noted time and the number of times when opening, this record can be used as the foundation to stealing people punishment, thereby can prevent stealing effectively.

The purpose of this utility model is achieved through the following technical solutions.The anti-electricity-theft multi-rate electric energy meter of wide operating voltage is made up of table drain pan, table lid, nameplate, terminal base, end cap, printed board and display (register shows or liquid crystal display), after linking, printed board and display be contained in the table drain pan, nameplate is stuck in Biao Gainei, table covers on the table drain pan, terminal base is contained in the lower frame of table drain pan, and end cap covers on terminal base.The magnetic force contact is housed on the optional position of printed board and terminal base, with in the printed board with terminal base on the corresponding nameplate in magnetic force contact position on and end magnetic element is housed on the covering position.

Anti-electricity-theft principle of the present utility model is, pre-buried magnetic element in the manufacture process of nameplate and end cap, pre-buried magnetic force contact in the manufacture process of terminal base, the magnetic force contact also has been installed in printed board, magnetic force contacts mates action on magnetic element on nameplate and the end cap and printed board and the terminal base, when the magnetic element on nameplate or the end cap away from or during near the magnetic force contact, force the magnetic force contact move/to close, thereby produce high level/low level signal, this signal is delivered to the I/O interface of single-chip microcomputer, start the number of times of recorder cpu record magnetic force contact action, move/close the time when changing, can write down that unauthorized people (electricity filching person) opens the number of times of end cap or table lid privately and the time when opening.

The beneficial effects of the utility model are energy unauthorized people of accurate recording (electricity filching person), open the number of times of end cap and Biao Gai and the time when opening privately, thereby can determine whether ammeter has the suspicion of stealing, can in time find and prevent stealing, can investigate in accordance with the law electricity filching person.

Description of drawings:

Accompanying drawing 1 is the structural representation of pulling down behind table lid and the end cap of the present utility model, and Fig. 2 is the left view after Fig. 1 loads onto table lid and end cap, Fig. 3 be Fig. 1 load onto show to cover and end cap after view.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail, in the accompanying drawing: 1---the table drain pan; 2---the table lid; 3---end cap; 4---shunt; 5---terminal base; 6---short-circuit piece; 7---nameplate; 8---printed board; 9---magnetic element; 10---the magnetic force contact.The utility model is when implementing, circuit does not originally change, table drain pan 1 and end cap 3 used materials are still made with the flame-proof ABS injection moulding, nameplate 7 is still made with the anti-flaming transparent polycarbonate, the turnover line of electric energy meter connects with the circuit of table in the inner printed board 7 through terminal base 5, and all electronic components are contained in the printed board.The course of work of its metering is with original the same, be that the electric energy that the user consumes is delivered to electronic multiplier to the sampled signal on shunt 4 and the resitstance voltage divider, product is that power signal is to time integral, A/D conversion becomes with the institute directly proportional electrical energy pulse of consuming electric power goes drive stepping motor, drives register accumulative total and also shows electric weight.Magnetic element 9 permanent magnet manufacturing, magnetic force contact 10 are magnetic switchs.

Claims

1. anti-electricity-theft multi-rate electric energy meter of wide operating voltage, form by table drain pan, table lid, nameplate, terminal base, end cap, printed board and display, after linking, printed board and display be contained in the table drain pan, nameplate is stuck in Biao Gainei, table covers on the table drain pan, terminal base is contained in the lower frame of table drain pan, end cap covers on terminal base, it is characterized in that on the optional position of printed board and terminal base, being equipped with the magnetic force contact, with in the printed board and on the corresponding nameplate in magnetic force contact position on the terminal base and end magnetic element is housed on the covering position.
