Several types of ion static eliminators
Ion Static Eliminator It consists of a high-voltage power generator and a discharge electrode that ionizes air into a large number of positive and negative ions by a high-voltage corona discharge, and then blows a large amount of positive and negative ions to the surface of the object to neutralize static electricity.
Ion static eliminators can be divided into the following types:
1. DC corona products
The DC high voltage generator raises the input voltage of 220V and outputs positive voltage and negative voltage respectively. A strong electric field is generated between the positive and negative discharge electrodes, the air molecules are ionized, positive ions are generated at the tip of the positive electrode, and negative ions are generated at the tip of the negative discharge electrode. Negative ions are simultaneously generated to neutralize the surface of the object. When the surface of the charged object is positive, the negative ions will neutralize.
2. AC corona products
The AC high voltage generator raises the 220V input voltage to above 4KV, and the discharge electrode alternates into a positive voltage and a negative voltage at a frequency of 50 Hz. A strong electric field is generated between the discharge electrode and the ground electrode, the air molecules are ionized, and the positive and negative ions are alternately generated at the tip of the discharge electrode. When the surface of the charged object is positive, the negative ions will be neutralized, and the AC corona product must be grounded to work normally, but some positive and negative ions will be directed to the ground due to grounding, and the positive and negative ions have good balance.
3. Pulse DC Corona Products
The pulsed DC high voltage generator raises the input voltage of 220V and alternately outputs a positive voltage and a negative voltage in a period of 4-6 seconds to act on the discharge electrode, thereby alternately generating positive and negative ions. Since the switching period of the pulsed direct current positive and negative ions is higher than the power frequency alternating current The static eliminator is 200-300 times longer, so there is no self-neutralization of positive and negative ions, and no positive and negative ions are lost without grounding, and the conversion period can be adjusted according to the distance of the electrostatic object to be removed. The distance is long and the conversion period can be long. When the distance is close, the time can be short. In the case of a pulseless DC static eliminator, the positive and negative ions can reach a very long working distance.
