Description
Technical field:
The utility model relates to a kind of watt-hour meter, especially single-phase active watt-hour meter.
Background technology:
Single-phase active watt-hour meter is used for the metering of single-phase electricity consumption.The present domestic single-phase active watt-hour meter great majority that use are Ferraris instrument, mainly by a rotatable aluminium dish and respectively a potential winding and the current coil on the iron core formed, as DD826 type, DD28 type watt-hour meter, DD16 type and DD14 type watt-hour meter etc.These watt-hour meter have only the function of metering electricity consumption, do not have anti-electricity-theft function, and some people that harbor evil intentions are had time can bore, and utilizes various means stealings, for example, disconnected house lead in zero line, on the spot line or zero line do not change watt-hour meter in addition; The phase line zero line reversal connection of house lead in or advancing phase line and going out the phase line reversal connection, make watt-hour meter counter-rotating etc.Cause damage to country, harm others to benefit oneself, be unfavorable for that the safety of country and society is united.
Summary of the invention:
The purpose of this utility model provides a kind of power-steeling preventing electric meter, and it should be able to prevent stealing effectively.
The utility model comprises single-phase active watt-hour meter, and this watt-hour meter has phase line to advance connection terminal 1 and 2, phase line goes out connection terminal 3, and zero line advances connection terminal 4 and zero line goes out connection terminal 5, it is characterized in that:
On each connection terminal 1～5, respectively be connected with by first, second relay, and the burglar-proof electric circuit of bidirectional triode thyristor, luminous neon tube, photoresistance, triggering electric capacity and some resistance formation; Wherein, first relay control phase line is entered connection terminal 1 and 2, and the circuit control phase line that contains second relay, bidirectional triode thyristor, luminous neon tube and photoresistance goes out connection terminal 3, zero line advances and go out connection terminal 4 and 5;
Described zero line goes out connection terminal 5 and only is connected with the load extension line with the moving contact of second relay.
The power-steeling preventing electric meter of said structure, under the normal condition, the first relay work of burglar-proof electric circuit, when remaining circuit is not all worked, watt-hour meter normal supply power supply.When electricity filching person with disconnected zero inlet wire in addition on the spot, during the zero line stealing, first relay does not have the work loop, does not work, and does not have electricity from the output of output phase terminal.When with phase line and zero line reversal connection input ammeter, contain the circuit working of second relay, bidirectional triode thyristor, luminous neon tube and photoresistance, the contact of second relay disconnects the output zero line, and load can not have access to electricity.When phase line being advanced and go out reversal connection, the common electrical kilsyth basalt reverses, and originally anti-electricity-theft ammeter is because of the reversal connection of this phase line into and out of line, and first relay is not worked, thus there is not electricity from watt-hour meter output, can't stealing.Thereby reach the purpose that prevents stealing.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is elaborated.
Shown in Figure 1, be the structural principle synoptic diagram of existing watt-hour meter.
Shown in Figure 2, be the structure principle chart of the utility model watt-hour meter.
Embodiment:
Fig. 1 is the structural principle synoptic diagram of existing watt-hour meter P, in the drawings, the watt-hour meter P in the frame of broken lines, phase line is wherein advanced connection terminal 1 and 2 and is communicated with, and terminal 3 is for phase line goes out terminals, and terminal 4 is that zero line advances terminals, and terminal 5 is that zero line goes out terminals.Be connected to load F on the extension line between terminal 3 and the terminal 5, terminal 1 meets input phase line L, and terminal 4 meets input zero line N.This is structure and wiring under normal the use.
Shown in Figure 2, be the structure principle chart of the utility model watt-hour meter, it increases and has connect by first relay J on each connection terminal 1～5 of former watt-hour meter P (in the frame of broken lines)
