In the specific steps, contact resistance exists at the metal contact surface in the crimping process, the secondary wiring contact resistance increases the secondary side impedance of the current transformer, so that the verification error of the transformer is increased, and a mathematical model of the secondary side wiring contact resistance and the verification error is required to be studied.
The influence of the crimping resistor of the secondary side connection of the current transformer on the verification result of the current transformer is analyzed. The number of turns of a primary coil of the current transformer to be detected is N1, and the current is I1; the number of turns of the secondary side coil is N2, and the induction current is I2; when the compression contact resistance is zero, the secondary side load is represented by Z2; without loss of generality, the secondary side pressure line contact resistance is expressed by an impedance parameter and is expressed as delta Z; the inner diameter of the current transformer iron core is r1, the outer diameter is r2, and the height is h. According to the ampere loop theorem, can obtain
2πrH＝N 1 I 1 -N 2 I 2 (1)
Wherein H is the magnetic field intensity in the iron core; r= (r1+r2)/2 is the average radius of the core.
The iron core of the current transformer is made of a magnetic material with high magnetic conductivity (such as ultracrystalline), and in a linear region, the magnetic induction intensity B of the iron core is a linear function of the magnetic field intensity H, and the magnetic conductivity mu meets the requirement
Based on the law of electromagnetic induction and ohm law, the equation of the secondary side loop of the current transformer can be expressed as
Wherein s= (r 2-r 1) h is the cross-sectional area of the core. dB/dt in equation (3) can also be written as
And deriving (1) to obtain
The ratio of the primary coil current to the secondary coil current can be obtained by adopting the phasor method and combining the two (3) - (5), namely
According to the above, when the secondary side load and the line pressing resistance are considered, the error generated by the current transformer complex ratio measurement is that
The loss angle of the iron core of the current transformer is theta, the total impedance angle of the secondary side (including Z2 and delta Z) is phi, and the formula (7) can be expressed as the form of a ratio difference and an angle difference, namely
(8) The formula (9) defines the mathematical physical relation between the crimping contact resistance of the secondary side connection of the current transformer and the verification result (the ratio difference f and the angle difference delta) of the transformer. It is obvious that the changes of the current transformer caused by the line pressing resistance of the secondary side line pressing are in linear relation with the line pressing contact resistance value as a result of the detection of the ratio difference f and the angle difference delta of the current transformer, and the size of the ratio coefficient is related to the iron core material characteristic, the secondary impedance, the number of turns of the secondary side line pressing, the iron core shape parameter and the like of the transformer.
