Abstract
The utility model belonging to a half wave DC anti-stealing electronical power meter is provided. The electronical power meter is internally provided with a through current transformer, the through current transformer is arranged on an electric wire of entrance of electronical power meter. The two leads at two ends of the through current transformer coil are connected with the input end of the power meter transformer. The iron core of the through current transformer is made from super-micro crystal materials and iron based non-crystal materials. The utility model has the advantages of half wave DC anti-stealing.
Description
Technical field
The utility model belongs to a kind of electron watt-hour meter.
Background technology
Traditional digital kilowatt-hour meter comprises the metal iron pan of a rotation, and each is decided according to employed electric weight by the formed magnetic field of electromagnet size by an electromagnet of being made up of current coil and iron core and potential winding and iron core up and down for it.The interaction of magnetic field and metal iron pan can make the metal dish rotation, and the number of times that it rotated is then automatically calculated and its numerical value is presented on the instrument.Digital kilowatt-hour meter metering property difference and fragile, now replaced by electron watt-hour meter gradually, but if be provided with rectifier cell entering on the electrical lead of electron watt-hour meter, the waveform that becomes sinusoidal ac is during into the half-wave rectification ripple, though power supply is powered to load circuit, electron watt-hour meter normally (few usually metering) shows power consumption, and the formation stealing causes the power supply unit loss.
Summary of the invention
Therefore, the purpose of this utility model is the electron watt-hour meter of a kind of anti-half-wave DC stealing of design, makes it have the effect of anti-half-wave DC stealing.For this reason, the utility model adopts and be provided with a through-type current transformer in electron watt-hour meter, described through-type current transformer is set on the electrical lead that enters electron watt-hour meter, the coil two ends lead-in wire of through-type current transformer joins with the meter transformer input end, and the iron core of described through-type current transformer is the iron core made from ultramicro-crystal material and iron based amorphous material.The said structure design has reached the purpose of this utility model.
The utility model has the advantages that the through-type current transformer that employing is comparatively sensitive, can accurately measure the electric current of the direct current composition that contains in the power supply, stop stealing, avoid the power supply unit loss.
Description of drawings
Figure is a structural representation of the present utility model
Specific embodiments
As shown in the figure, electron watt-hour meter of the present utility model is a known technology, so be not repeated.The utility model improvement part mainly is a through-type current transformer as shown in the figure.A kind of electron watt-hour meter of anti-half-wave DC stealing is made up of the electron watt-hour meter summation current transformer.Be provided with a through-type current transformer in the electron watt-hour meter, described through-type current transformer is set on the electrical lead that enters electron watt-hour meter, the coil 3 two ends lead-in wire 1 of through-type current transformer joins with the meter transformer input end, and the iron core 2 of described through-type current transformer is the iron core made from ultramicro-crystal material and iron based amorphous material.
Hub of a spool hole on the iron core in the housing 4 two ends corresponding housing of described through-type current transformer is provided with through wires hole 5.
The iron core of described through-type current transformer is the iron core made from ultramicro-crystal material and cobalt base amorphous body material.
The iron core of described through-type current transformer is the iron core made from cobalt base amorphous body material.
During use, in electron watt-hour meter, be provided with a through-type current transformer, pass the through wires hole of through-type current transformer at an electrical lead that enters electron watt-hour meter, the coil two ends lead-in wire of through-type current transformer joins with the meter transformer input end, as long as electric current is arranged by being positioned at the electrical lead of through wires hole, all can be arrived by the coil-induced of through-type current transformer, the coil induction current metering circuit that imports electron watt-hour meter into again can be stopped stealing effectively, avoids the power supply unit loss.
In a word, the utility model adopts comparatively sensitive through-type current transformer, can accurately measure the electric current of the direct current composition that contains in the power supply, stops stealing, avoids the power supply unit loss.Can form unified advantage of making.
