Abstract
The utility model relates to an energy-saving single-phase electric meter which is characterized in that a radial turntable comprises an outer-circle conducting wire and a radial conductor, and two drive loops are symmetrically arranged at both ends of the radial turntable. A brake magnet is arranged between the two drive loops. The center of the radial turntable is provided with a turntable shaft. The other end of the turntable shaft is provided with a screw thread gear which is engaged with a rotational part to drive a counter to work.
Description
The utility model relates to a kind of measurement instrument that measures electrical appliance power consumption, a kind of energy-saving single-phase watt-hour meter of more specifically saying so.
At present, the structure of prevailing civilian single-phase watt-hour meter is made up of potential winding, current coil, aluminium rotating disk, brake magnet, running part and register.Potential winding two termination 220V AC power, current coil with connect the 220V AC power after electrical appliance is connected.When having electric current to pass through in the current coil, the alternating magnetic field that current coil produces, make in the aluminium rotating disk and produce eddy current, because the magnetic field that this eddy current places potential winding to produce, therefore, the aluminium rotating disk just rotates under potential winding and current coil effect, and drives the register numeration by running part, still, no matter electrical appliance electricity consumption or not electricity consumption, potential winding is all in power consumption, especially during not electricity consumption of electrical appliance, when promptly no current passes through in the current coil, potential winding is still in power consumption, cause waste of energy, and this watt-hour meter, circuit structure complexity, cost height.
The purpose of this utility model is to avoid the weak point of above-mentioned background technology and a kind of energy-saving single-phase watt-hour meter is provided, it can not only measure the power consumption of electrical appliance, and can be when not electricity consumption of electrical appliance, watt-hour meter self not consuming electric power, and during the electrical appliance power consumption, himself power consumption is littler than common single-phase watt-hour meter self power consumption; Circuit structure is simple, cheap.
The purpose of this utility model is achieved in that a kind of energy-saving single-phase watt-hour meter, by rotating disk, brake magnet, running part, register is formed, it is characterized in that: rotating disk is a kind of radial rotating disk, the radiation rotating disk is to be made of outer ring lead and the radial conductor of Duo Gen, the center that many radial conductor dbus are crossed the outer ring lead is connected on the lead of outer ring, by the cross one another many radial conductors in lead center, outer ring mutually insulated each other, iron core in the drive coil (electromagnet) is notched hollow square, radial rotating disk passes the hollow space of this drive coil, the iron core of another drive coil (electromagnet) is a shape, this drive coil is placed the bottom of radial rotating disk, perpendicular to radial rotating disk, its cross section is near radial rotating disk, and two drive coils (electromagnet) symmetry is installed in the two ends of radial disk diameter; Respectively twine two groups of coils on these two drive coil iron cores, the magnetic circuit of the lead that it twined is consistent.
Brake magnet is installed in the middle of the radial rotating disk between two drive coils (electromagnet), and four groups of coils on two drive coils (electromagnet) are corresponding in twos in parallel.Two parts are in series by electrical appliance then.
Owing to adopted technique scheme, the utlity model has following beneficial effect: 1, ammeter when A, B point does not connect that no current passes through in electrical appliance or the circuit, this not power consumption of ammeter, rotating disk is motionless; 2, in metering electrical appliance power consumption, self power consumption of watt-hour meter is dropped to bottom line, and circuit structure is simple, reliable operation, with low cost.
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is a circuit diagram of the present utility model;
Fig. 3 is the structural drawing of radial conductor among Fig. 1.
Among the figure, the 1st, radial conductor, the 2nd, outer ring lead, the 3rd, brake magnet, the 4, the 5th, drive coil (electromagnet), the 6th, turntable shaft, the 7th, running part, the 8th, counter, the 9th, 220V alternating current terminals, the 10th, electrical appliance terminals, the 11st, radial conductor center pit.
The utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1, be connected with outer ring lead 2 by the radial conductor 1 that is evenly distributed, form radial rotating disk, many radial conductors 1 that evenly are equally spaced are superimposed with each other by the center of outer ring lead 2, many radial conductors 1 make it to separate with being coated with insullac each other, and mutually insulated.Drive coil 4(electromagnet) hollow bulb passes radial rotating disk and installs, drive coil 5(electromagnet) installs perpendicular to radial rotating disk, and drive coil 4(electromagnet) and drive coil 5(electromagnet) symmetry is contained in the two ends of radial disk diameter, brake magnet 3 is contained in drive coil 4(electromagnet) and drive coil 5(electromagnet) in the middle of radial rotating disk in the middle of, it is fixing that turntable shaft 6 one ends pass shaft hole 11, and the other end is equipped with helical gear 12 and makes counter 8 display digits by running part 7.For making radial rotating disk have higher physical strength, evenly pour into a mould one deck duroplasts on the surface of radiation rotating disk and make it moulding, make rotating disk more symmetrically.Drive coil 4(electromagnet) iron core gap should be about 0.5 centimetre, and drive coil (electromagnet) 5 core sections should be in 0.5 centimetre apart from the distance of rotating disk.Radial conductor 1 and outer ring lead 2 are all made with very thin copper sheet, and it is firm that radial conductor 1 two ends and outer ring lead 2 should be connected.When 220V ac power supply terminal 9 inserts the 220V alternating current, after electrical appliance terminals 10 two ends connect electrical appliance, drive coil 4(electromagnet), drive coil 5(electromagnet) just there is electric current to flow through in, drive coil 5(electromagnet) alternating magnetic field that produces makes the drive coil 5(electromagnet of radial rotating disk) produce induction current in the radial conductor 1 of top, this induction current forms current return through outer ring lead 2, and this radial conductor 1 other end just is arranged in drive coil 4(electromagnet) magnetic field that produces, radial like this rotating disk just rotates under this two parts drive coil (electromagnet) effect, drives counter 8 countings by running part 7.
In Fig. 2, drive coil 4(electromagnet) C part and D partly respectively with drive coil 5(electromagnet) C ' partly, D ' part is in parallel, two parts are connected through electrical appliance then, and the insulation degree between these two groups of coils should be able to be born over the ground (iron core frame) electric shock more than 1 kilovolt.
In Fig. 3, radial conductor 1 is all coated insullac except that two ends, and the superimposed part of each radial conductor is not contacted, and mutually insulated.
