Melt blown fabric electrostatic polarizer (electrostatic generator)

Melt blown fabric electrostatic polarizer (electrostatic generator)It is an advanced voltage withstand test equipment designed according to the national power industry standards, used to conduct insulation strength tests on various electrical products, electrical components, insulation materials, etc. under specified voltages, to assess the insulation level of the products, discover insulation defects of the tested products, and measure the ability to withstand overvoltage.

It can detect concentrated defects with high risks and plays a decisive role in determining whether power equipment can continue to operate. It is an important means to ensure the insulation level of equipment and avoid insulation accidents.

Usage conditions:

The workplace should be free of gases, vapors, chemical dust, and other explosive and corrosive media that seriously affect insulation.
● Environmental temperature: 0-40 ℃
● Environmental humidity: ≤ 85% RH (no condensed water)
● Altitude: ＜ 1000m

Structural features:

1. In terms of insulation structure layout, based on the principle of 'distance effect' of transformer oil, multi-level insulation is adopted, and the internal insulation of the transformer is divided into multiple oil channels, thereby improving the insulation degree and reducing the volume.

2. To solve the problem of oil leakage in LE transformers, the TDM series transformers do not have oil reservoirs. Therefore, when the temperature is too high, the oil expands and leaks out from the oil nozzle. This series of products sets the oil injection hole at the top of the sleeve, and the oil in the sleeve is connected to the oil in the body of the transformer. So in addition to its functions of installing silicon stacks, short-circuit rods, and string rods, this sleeve also serves as a transformer oil reservoir.

3. The high voltage output end of the TDM series transformer is sealed with epoxy resin. Due to the large amount of bubbles generated when epoxy resin is injected under normal conditions, discharge occurs at the high voltage lead part. Then a metal component is used to fix the lead pen and evenly apply pressure, thereby eliminating the discharge phenomenon.

4. This series of product fuel tanks has a compact structure, novel appearance, and small volume and weight.

5. The iron core is a single frame core type, consisting of 0.30mm cold-rolled silicon steel sheets stacked together and tightened with new special materials, replacing the traditional through core screw. The coil is a concentric cylindrical multi-layer tower structure.

Melt blown fabric electrostatic polarizer (electrostatic generator)characteristic:

1. The charging effect of an electrostatic generator is closely related to the structure and installation of the ion emitter (rod), and generally the ion emitter (rod) needs to be customized on site.

2. Do not use electrostatic generators in flammable and explosive environments.

3. The grounding terminal of the electrostatic generator must be truly grounded, otherwise it will affect the charge effect and generate unsafe factors.

4. Do not aim the firing pin of the electrostatic emitter (rod) at the human body.

5. The electrostatic generator has a short-circuit protection device inside, but frequent short-circuit ignition of the output should be avoided, otherwise the protection device may also be damaged due to fatigue

matters needing attention:

1. The discharge needle of the electrostatic emitter should be kept away from the metal mounting bracket of the emitter, and an insulating material should be used as the bracket.

2. In order to apply sufficient static electricity to the material, there must be a flat "metal pallet" or "metal mesh plate" on the back of the material to be charged with static electricity. This metal support plate is connected to the "earth", which is the working grounding of the DC high-voltage supply, in order to form a "circuit" for electrostatic discharge.

3. In order to add sufficient static electricity to the material and prevent it from leaking (escaping) quickly after adding static electricity. The higher the insulation value of the material, the better. The drier the materials and ambient air, the better.

4. Do not discharge the electrostatic discharge needle towards the bare metal plate, as the area of the material subjected to static electricity is equal to the area of the metal plate. If the area size of the material to be electrostatically charged changes and the area or length of the electrostatic emitter cannot be changed, then place a thick insulating material on the bare metal support plate to cover it, or cover the discharge needle facing the bare metal support plate, which is conducive to the concentration of charges on the material that needs to be electrostatically charged.

5. Good operational performance, the magnitude of voltage and current determines the adsorption force of meltblown fabric

6. Stable and reliable. Due to the unstable operation of the equipment under high voltage, it is highly susceptible to damage.

7. Ensure the safety of the electrostatic generator as 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 meltblown fabric. The use of non electric shock technology, overload protection technology, and continuously adjustable voltage and current technology is the preferred choice for non-woven meltblown fabric with electrostatic equipment.
