Abstract

The utility model discloses an instrument for alarming and recording charge-evading of users, which is composed of a magnetic ring transformer, a bridge rectifier, a filtering capacitor, a clock, and other unit capacitance elements. Because of electric larceny, electric currents flowing cross a magnetic ring are unbalanced, which generates corresponding unbalanced AC voltage which is converted into DC voltage by rectifying and filtering. Thus, the clock starts to time and a light emitting diode emits light to alarm. The utility model can alarm, accumulate, and time for electric larceny modes, such as one line to one ground, one line to one null line, upward flow and reverse codes, etc. The utility model has the advantages of simple structure, low cost, convenient installation, no additional line connection, less power consumption, low working voltage, small electric currents, safety, and stability; the instrument for alarming and recording charge-evading of users does not exist the problems of high insulation and high heat dissipation.

Description

Single-phase stealing alarming recording chronograph

The utility model relates to a kind of device of taking precautions against stealing, relates in particular to a kind of device that single-phase stealing is warned and clocked and act on that plays.

Raising along with electric utility development and resident living level, resident's electric load is also increasing, because the part resident lacks the consciousness of electric power as a kind of commodity, such or such stealing electricity phenomenon therefore occurs, caused a large amount of electric energy to run off, adopted great loss to the power supply department band.At present, resident's stealing mainly contains following three kinds of modes: one is a line one ground formula; Two is a line one zero formulas; The 3rd, up-flow is a sign indicating number formula.And the residential electricity consumption person is huge numbers of families, the power supply department manpower carries out the stealing inspection to all users, manpower scope in one's power can only be minimum part, especially adopt the up-flow stealing of falling the coding mode hard to guard against especially, because this method is easy, quick, and carry out at night mostly, fallen the sign indicating number after do not stay any vestige.Also there is not a kind of monitoring arrangement that can effectively monitor above-mentioned three kinds of mode stealings in the market.

The purpose of this utility model is: overcome the above-mentioned defective of prior art, a kind of single-phase stealing alarming recording chronograph other wiring and that can effectively monitor stealing that need not is provided.

The technical solution of the utility model is: it is made up of a magnetic ring transformer, Qiao Dui, clock and other Resistor-Capacitor Unit, obtains induction current by transformer, carries out rectification through the bridge heap, when providing DC voltage that clock is walked, thereby finds the stealing time.

The utility model also is provided with light emitting diode for ease of monitoring in foregoing circuit, and cross-over connection piles output terminal in bridge, and is luminous when the bridge heap has output voltage, i.e. luminous during user's stealing.

The utility model falls the accumulation of all can warning of three kinds of stealing modes of sign indicating number to a line one ground, a line 1, up-flow and clocks, simple in structure, cost is low, volume is little, all can install in the existing watt-hour meter box, need not to consider to enlarge its volume and lead sealing problem, and easy for installation, only need allow watt-hour meter inlet wire or outlet (two) pass its magnet ring hole and get final product.The utility model not power consumption at ordinary times, only power consumption when user's stealing, and power consumption little (about 1.5mn); Its operating voltage is low, and electric current is little, and safety and stability does not exist high insulation, high heat dissipation problem, even when big electric current passes through,, still do not have dynamic stability and thermally-stabilised problem because magnetic speed is saturated, and durable in use, must not burn out, cause the problem of fire.

Accompanying drawing: be the utility model circuit diagram.

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is by magnetic ring transformer B, bridge heap D ₁～D ₄, filter capacitor C, resistance R, diode D ₅～D ₆And clock T forms.B level of transformer meets bridge heap D ₁～D ₄Input end, bridge heap D ₁～D ₄Output terminal also is connected to filter capacitor C and resistance R and diode D ₅, D ₆Series arm, diode D ₅, D ₆The two ends cross-over connection of series arm has clock T, and provides the DC voltage of clock by it.The utility model is also at bridge heap D ₁～D ₄The output terminal cross-over connection has light emitting diode D ₇

Principle of work of the present utility model is: because magnetic ring transformer magnet ring hole is passed in the inlet wire or the outlet of watt-hour meter, as user not during stealing, current balance type in the transformer magnet ring, inferior line are output as zero, no alternating voltage produces, when the not luminous and clock of light emitting diode is not walked; In case when user's stealing, because out-of-balance current produces corresponding alternating voltage, alternating voltage is piled D through bridge in the magnet ring ₁～D ₄And become DC voltage behind the capacitor C rectifying and wave-filtering, and lumination of light emitting diode, the clock both end voltage can reach about 1.3～1.5 volts simultaneously, thereby promotes its timing.
