Abstract
The utility model relates to an energy-saving active watt-hour meter which belongs to an electric work metering device, comprising a mutual inductor loading a live wire, a triggering conduction apparatus which is provided with a both-way conducting circuit and connected with the mutual inductor, and a voltage coil connected with the triggering conduction apparatus. The utility model has the characteristics of simple structure, reasonable design, reliable performance, easy installation, and obvious energy saving effect.
Description
The utility model is a kind of meritorious energy-saving kilowatt-hour meter, belongs to a kind of electric power measurement device.
Existing single-phase watt-hour meter generally is made up of potential winding, current coil, worm screw, worm gear, aluminium dish and counter.When its work, voltage is added on the coil, and load current causes the variation of magnetic flux, and further produce vortex flow on the aluminium dish by current coil, and these vortex flows are subjected to the electromagnetic force of the magnetic flux that potential winding produces, and the aluminium dish is rotated.The magnetic flux of potential winding also can produce vortex flow on the aluminium dish, these vortex flows also can be subjected to the influence of the electromagnetic force of the magnetic flux that current coil produces.In the time of the load electricity consumption, under the acting in conjunction of these electromagnetic forces, the aluminium dish just constantly rotates, and the worm screw on the aluminium dish axle drives the worm gear on the register, and register is constantly advanced, and makes the electric weight indication.This watt-hour meter is still electricity consumption of potential winding under the idle state of load, and its current value can reach 0.01A, so it wastes greatly the waste electric energy.And waste electric energy sometimes and can also cause the little commentaries on classics of aluminium dish and send sound of movement.
The purpose of this utility model is: design a kind of energy-conservation active watt-hour meter.
The utility model comprises the mutual inductor of load live wire, the triggering and conducting device that has the two-way admittance circuit that is connected with mutual inductor and the potential winding that is connected with the triggering and conducting device.
The utility model is to be the electric current that live wire causes mutual inductor by load, again by the work of triggering and conducting circuit control potential winding, and potential winding work when making loaded work piece, potential winding is not worked during the load outage, thereby reaches the purpose of economize on electricity.Two-way trigger circuit in the trigger circuit can guarantee can both work when electric current is in positive half cycle and negative half period.
Said mutual inductor comprises a magnet ring and the mutual inductor that is wrapped on the magnet ring is formed, and the load live wire passes magnet ring, and an end of mutual inductor is connected with the trigger end of trigger circuit in the triggering and conducting device respectively.When the load live wire has electric current to pass through, produce electric current on the mutual inductor under the effect of magnet ring, thereby starting the work of triggering and conducting device, make the circuit turn-on work of potential winding.When load is cut off the power supply, there is not electric current on the mutual inductor, the triggering and conducting device is not worked, the down circuitry at potential winding place, thus there is not energy consumption.
Two-way trigger circuit in the said triggering and conducting device comprise two circuit by controllable silicon and diode series connection, these two circuit are parallel with one another, controllable silicon is opposite with the positive and negative electrode of diode in two series circuits, and the two ends of mutual inductor are connected with negative pole with two silicon controlled trigger ends respectively.Like this, the ac signal in the mutual inductor makes the conducting respectively of two controllable silicons, makes the potential winding continuous working.
Can have two mutual inductors on the said magnet ring, each mutual inductor is connected with a controllable silicon in the triggering and conducting device realizes control respectively.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is a block scheme of the present utility model;
Fig. 2 is the circuit diagram of the utility model embodiment user mode;
Wherein, 1-mutual inductor, 2-triggering and conducting device, 3-power lead, 4-potential winding.
As shown in the figure, the utility model is made up of potential winding 4, current coil, worm screw, worm gear, aluminium dish and counter mutual inductor 1, triggering and conducting device 2.Mutual inductor 1 comprises a magnet ring h, and the load live wire passes magnet ring h, also is wound with mutual inductor L on two on the magnet ring h
