LZZBJ9-35 Casting Resin Indoor High Voltage Current Transformer
The primary coil is in series in the circuit, and the number of turns is very small. Therefore, the current in the primary coil depends entirely on the load current of the circuit being tested, but not on the secondary current;
The current coil impedance of the current Transformer secondary coil and the relay are very small, so under normal circumstances, the current Transformer is running near short circuit.
The ratio of the first and second rated current to the current Transformer, called the rated mutual inductance ratio: kn = I1n / I2n
Since primary coil rated current I1n has been standardized and secondary coil rated current I2n has been unified to 5(1 or 0.5) Ann, the rated mutual inductance ratio of current Transformer has also been standardized. Kn can also be expressed roughly as the turn ratio of the first and secondary coils of the transformer, i.e. the turn ratio of N1. N2 to the first and second coils in the Kn _ kN = N1/N2.
There are two kinds of transformer, voltage Transformer and current Transformer. Voltage transformer can be used for measuring voltage and power in high-voltage and high-voltage power systems. The current Transformer can be used for the measurement of exchange current, the measurement of exchange voltage and the protection of power drag lines.
Voltage transformer
By purpose
Measurement winding of voltage Transformer or voltage transformer for measuring: To provide grid voltage information to measuring device within normal voltage range;
Protection winding of voltage Transformer or voltage transformer for protection: In the state of power grid failure, provide information on power grid failure voltage to relay protection devices.
