1. The dry reactor is smaller than the traditional oil-immersed reactor and hollow reactor, and has the characteristics of light weight, small space, simple structure and easy installation. 2. Temperature resistance grade Avenue F (155°C); During normal operation, the temperature rise of the core and coil of the dry- type core reactor does not exceed 90K. 3. The dry-type iron core reactor can operate for a long time at 1.35 times the rated current. 4. The noise of the dry-type iron-core reactor is not more than 65dB 5. The withstand voltage level of the dry Tiezhi reactor confor ms to JB5346-1998 "Series Reactance instrument.
Three-phase incoming reactor, also known as commutation reactor, is used in the incoming line of the power grid, thro ugh the AC current, its role is to limit the voltage drop on both sides of the converter commutation into the grid, su ppress the harmonic and thyristor current rise rate di/df a nd voltage rise rate du/dt, and the decoupling of parallel converter groups. It is able to limit the voltage jump of the grid and the inrush current produced during the operation of the grid system, protect the terminal electrical equipmen t, and suppress radio interference.
1. Reduce the noise of the motor and reduce the eddy curre nt loss. 2. Reduce the input higher harmonics. 3. It is used for smooth filtering, reducing the transient vo ltage dv/df, and prolonging the life of the motor. 4. Protect the power switching device inside the inverter.
1. The power supply has obvious interference (interference, overvoltage) to other equipment, 2. The voltage imbalance between the phases of the power supply > 1.8% of the rated voltage 3. Lines with very low impedance (power transformers are more than 10 times the rated value of the inverter) 4. A large number of inverters installed on a line to redu ce the line current 5. Use cosΦ (power factor) to correct the capacitance or power factor correction unit
