Its parameter size specifications can be quickly customized;
The damping resistor acts to effectively absorb the higher harmonic components of the secondary circuit of the rectifier transformer, prevent the output loop from resonating, and effectively protect the rectifier transformer. A damping resistor must be provided at the output of the rectifier transformer. In any case, it is absolutely not allowed to connect the rectifier transformer output directly to the electric field without a damping resistor.
The electrostatic precipitator rectifier transformer matches the parameter size of the damping resistor. Currently, there is no uniform standard in the country. The rated power of the damping resistor must be greater than the product of its resistance and the square of the secondary rated current, and a certain safety margin must be left.
At present, the damping resistors installed in the field are installed between the output of the rectifier transformer and the high-voltage isolating switch, and some are installed between the high-voltage isolating switch and the high-voltage introduction of the electric field. In theory, these two methods are connected. can. However, considering the convenience and safety of repairing and replacing the damping resistor, the damping resistor is connected between the output of the rectifier transformer and the high-voltage isolating switch. When the damping resistor at the output of a rectifier transformer needs to be repaired or replaced, the electric field is powered off. After the rear isolating switch is placed in the "grounding " position, the damping resistance can be reliably shielded to ensure personal safety, and the remaining adjacent electric fields can continue to operate. Because the electrostatic precipitator often runs several electric fields in series, if the damping resistor is connected between the isolating switch and the electric field high voltage, the electric field is powered off even if the isolating switch is placed " grounded ".
In position, the charged ions generated by the adjacent electric field can still be strung to the damping resistor.
It is well known that the complete disconnection of the damping resistor will result in an " output open circuit " and the electric field will trip. This situation is very obvious and is well judged. However, when the end of the damping resistor or somewhere in the middle falls off and the end of the resistance wire is close to " ground " , corona discharge is generated from the ground, and the result of the meter is very similar to the normal operation of the electric field. When checking the equipment, listen carefully to the discharge sound. If there is a discharge phenomenon at the damping resistor, it should be handled in time.
