Abstract
The invention provides with the real means of production, technical level, the investment ability method of the high precision of realization power measurement, wide range, measuring tube physics and chemistry.
Description
The invention belongs to the power measuring instrument field.
The present invention is different from conventional art.Research, production to improve each discrete device always improves system effect traditionally, although adopted a lot of advanced technologies and investment, system effect changes little.With the precision measure effect is example, adopts 0.5 grade of Wh, 0.2 grade of CT, 0.5 grade of PT, and its system accuracy does not also reach the direct measurement requirement of 3.0 grades of watt-hour meter.Technology, equipment, investment problem are not only arranged here, and a difficult problem has also appearred in standard metering.
The invention reside in from eliminating systematic error and start with, improve system accuracy, improve conventional art, improve the systematic survey effect.For example: with 2.0 grades of ammeter production equipments, technical capability and investments.By production of the present invention, just obtained the effect of 2.0 level system precision, 30 times of social economic effects, and can organize production immediately.Technology of the present invention, economic effect also are the success of measuring
Cardinal rule of the present invention is to utilize reality, transforms tradition, improves the systematic economy technique effect.
Previous example is exactly the scheme to China's systems engineering of electric power measurement.Its enforcement is to finish by following concrete technology:
1, improves the motor meter design.Main points are shell frame integrative-structures, mould heart garden dish and complex iron core.The latter is a performance-critical, and in this explanation: line is pressed the current ferric core inside surface to cutting Ge Si (goss) siliconized plate (as the M-3H of Nippon Steel Corporation)
Shape, renaturation invests former iron core (D22) inside surface after handling.
2, voltage transformation.Basically same capacitance type mutual inductor is added with electrical part, as figure.
R
1, L adjust to guarantee V, V
1Certainty ratio, same-phase.L
1Adjustment technology adopts " the electric calibration equipment of charging source " method.
3, current transformation.Material, technology are with the additional part of electric current inside surface.Design is with CE sections core.Specified magnetic flux is by 12000GS, and machine coiling, secondary are by 0.5A, and the verification coil is by 5A, and nominal operation magnetic potential 〉=100A circle is strained the same iron core of bandage.
4, remote control integrating mechanism." time-program switch " method of employing, pulse promotes counting assembly.The induction of shallow bid opening produced when pulse was turned round by disk.Remote signal gating pulse generation power supply.Remote signal is to be transferred to voltage component by electrical network.Voltage spare magnetic field causes frequency-selecting reed resonance, make pulse generation power supply.
Claims (5)
1, power measurement product, feature are to realize big power measurement and standard calibration by transducer.
2, power measurement product.Feature is in electromagnetic component with this structure siliconized plate of dagger-axe.
3, voltage changer.Feature is a capacitance partial pressure, and the resistance phase modulation is with " the electric calibration equipment of charging source " method pressure regulation.
4, power pack.Feature is a C sections structure.
5, remote control integrating mechanism.Feature is to utilize " time-program switch " method to promote integrator.
