Melt blown fabric with electrostatic polarizing device (polarizing rod)

Melt blown fabric with electrostatic polarizing device (polarizing rod)The use of 20-60KV-120KV high voltage operation belongs to equipment with high technical content. When choosing a non-woven electrostatic generator, the following points should be noted:
1. Good operational performance, the magnitude of voltage and current determines the adsorption force of the Kou cover cloth
2. Stable and reliable. Due to the unstable operation of the equipment under high voltage, it is highly susceptible to damage.
3. Ensure the safety of the non-woven fabric electrostatic generator, which is a high-voltage device. Improper selection can pose a risk of electric shock to the human body.
Both too large and too small can affect the production process of the Kou cover. The use of non electric shock technology, overload protection technology, and continuously adjustable voltage and current technology is the preferred choice for non-woven Kou cover cloth and electrostatic equipment.

matters needing attention:

1. Test personnel should divide responsibilities, set a safe distance at the test site, carefully inspect the grounding of the test sample and test transformer, and assign a dedicated person to monitor safety and observe the status of the test sample.

2. The main parts of the test sample should be cleaned thoroughly and kept absolutely dry to avoid damaging the test sample and causing errors in the test values.

3. For the testing of large equipment, it is generally necessary to first conduct a no-load test on the test transformer, that is, to increase the voltage to the test voltage without connecting the test sample.

4. When conducting a voltage withstand test, the boosting speed should not be too fast, and sudden pressure should be prevented. For example, if the regulator is not at zero position, it should be suddenly closed, and the power should not be suddenly cut off. Generally, it should be closed when the regulator drops to zero position.

5. During the boost or withstand voltage test, if any of the following abnormal conditions are found, such as large fluctuations in voltage and current meter data, abnormal noise from the tested object, burning or smoking of insulation, the voltage should be immediately reduced, the power should be cut off, the test should be stopped, and the cause should be identified.

When using this product for high-voltage testing, in addition to being familiar with this manual, it is also necessary to strictly follow relevant national standards and operating procedures.
