    Product Description: 100kV 120kv 30mA melt blown cloth electrostatic electret 1. Melt blown cloth electrostatic electret machine, melt blown cloth electrostatic electret high voltage generator, non-woven melt blown cloth high-voltage electrostatic generator, oil immersed electrostatic generator, melt blown cloth electrostatic generator, melt blown cloth electrostatic electret, melt blown cloth electrostatic electret equipment. 2、 Overview of melt blown Fabric Static electret: Yinxi is a professional manufacturer of high voltage testing equipment and voltage stabilizing equipment. The equipment is easy to operate and easy to move. The high-voltage electrostatic generator of melt blown cloth produced by Yinxi company is used for electrostatic dust removal. It can provide stable power supply for static electret equipment, ensure long-term and efficient work of electret equipment, and provide strong quality assurance for melt blown cloth of grade 90, 95 and 99. It is particularly important to ensure the quality of melt blown fabric. Electret treatment of melt blown nonwovens is an important finishing technology to improve its filtration efficiency. The melt blown nonwovens with electret finishing have the advantages of high filtration efficiency and low filtration resistance because they have persistent static electricity and can capture fine dust by electrostatic effect.

In the process of melt blown process, the fiber with permanent static charge can be made by using this electrostatic electret device. Polypropylene is an ideal material for electret fiber because of its high resistivity, large charge capacity and low RF loss. Electret air filtration, the filter material fiber itself charged, through electrostatic attraction of charged particles in the air, is also the neutral particles in the air after induction polarization, so as to filter submicron particles in the air more effectively. It can significantly improve the filtration efficiency without increasing air resistance. The filter efficiency of melt blown cloth can reach bfe99 or above after treated by this 100kV / 120kv electrostatic electret device. Electrostatic electret device is an electrostatic electret device with processing capacity of 1600mm width. The electrostatic generator is integrated in the interior. The electrostatic electret is connected with 100v120kv DC high voltage. It has the characteristics of high power, long-time operation without heating and high voltage level. (width and height can be customized according to customers) parameters and operating conditions of electrostatic electret device device power: customized cooling mode: natural cooling, long-term operation. Environment temperature: 25-55 ℃ ambient humidity: 10-90% RH (no condensation) there is no conductive, explosive dust, no corrosive metal and damage to the absolute green gas in the operation site. The input voltage is: AC220 V ± 10% 50 Hz, the environment is clean, the ventilation condition is good, the equipment needs to be grounded separately, and the grounding resistance is ≤ 2 Ω. This equipment is used for the electrostatic adsorption process of melt blown cloth mask. Pay attention to the following: the voltage of 20kV / DC is higher than that of 100kV, and the operation voltage of this device is higher 2. It is stable and reliable. Because the equipment works under the unstable state of high voltage, it is easy to be damaged. 3. To ensure the safety of non-woven electrostatic generator is a high-voltage equipment, improper selection may cause electric shock hazard to human body. If it is too large or too small, it will affect the production process of melt blown fabric. Adopting non electric shock technology, overload protection technology, continuous adjustable voltage and current technology, etc., is the choice of non-woven fabric melt blown cloth plus electrostatic equipment

  •  Power frequency withstand voltage test transformer

    Product description power frequency withstand voltage test transformer (power frequency voltage withstand test device) is a kind of light high voltage withstand voltage test equipment, which is produced based on the original similar products after a lot of improvement according to the "test transformer" standard issued by the Ministry of mechanical and electrical engineering. It is applicable to the fields of electric power, wire and cable, industrial and mining enterprises, scientific research and other fields Power frequency withstand voltage test and DC leakage test are indispensable instruments in high voltage test. YDJ power frequency AC / DC withstand voltage test device is composed of voltage regulating console and oil immersed high-voltage test transformer. The power frequency power supply is input to the operation box (or operation table), and the voltage is regulated by the auto voltage regulator to the primary winding of the test transformer, so that the power frequency high voltage can be obtained in the secondary (high voltage side) winding. This power frequency high-voltage AC can obtain high-voltage direct current after rectifying by high-voltage silicon stack and capacitor filtering, and its amplitude is 1.4 times of the effective value of power frequency high-voltage, but the short-circuit rod should be pulled out when using DC, and inserted into the short-circuit rod when using AC. The high-voltage test transformer adopts single frame core structure. The low-voltage winding and the high-voltage winding are coaxial wound. The primary low-voltage winding is wound on the iron core, and the secondary high-voltage winding is outside. This coaxial arrangement reduces the leakage flux and increases the coupling between windings. The iron core of the test transformer is made of high-quality cold-rolled oriented silicon steel sheets, and the fastening method is steel as clamp. The high-voltage coil is a cylinder multi-layer tower structure, which is made of high-quality polyester enameled wire and high-voltage insulation materials. The overall structure of the product is compact, universal, easy to use and carry. The shell is made into octagonal structure with better matching with the device core. The overall appearance is beautiful and generous. Structure diagram of test transformer 1 - short circuit pole D 2 - equalizing ball 3 - high voltage bushing 4 - transformer handle 5 - oil valve 6 ~ 7 - secondary voltage input a, x 8 ~ 9 - measuring terminal e, f 10 - grounding terminal of transformer shell 11 - high voltage tail x 12 - high voltage output a 13 - high voltage silicon pile 14 - Transformer Oil 15 - iron core 16 - secondary low voltage winding 17 - measuring winding In the test transformer, a and X are low-voltage input terminals, e and F are instrument measuring terminals, and a and X are high-voltage output terminals. In terms of insulation structure, according to the principle of "distance effect" of transformer oil, multi-level insulation is adopted, and The internal insulation is divided into multiple oil channels, so as to improve the insulation degree and reduce the volume; 2. The oil leakage problem of the transformer is solved. Because the former transformer has no oil reservoir, when the temperature is too high, the oil will expand and leak out from the oil nozzle. In this series of products, the oil injection hole is set on the top of the casing, and the oil in the sleeve is connected with the oil in the body. Therefore, in addition to the functions of silicon stack, short circuit rod and series excitation rod, the bushing is also equivalent to transformer oil reservoir; 3. The series of products adopt metal fixed lead wire and voltage equalizing, so as to eliminate the discharge phenomenon; 4. The oil tank has compact structure, novel appearance, small volume and light weight; the test transformer above 10KVA is equipped with movable iron wheel, which is easy to move. 5. The iron core is single frame core type, which is composed of DQ type, 0.30mm cold-rolled oriented silicon steel sheets, and fastened with new special materials, instead of the traditional core screw. It is a multi-layer cylinder structure. Specifications and parameters of test transformer: 1. Basic model, specification, capacity and quantity of transformer; 2. Primary and secondary voltage of transformer (input and output voltage); 3. Capacity distribution of each voltage and whether multiple groups of voltage are used at the same time 4. The appearance and size shall be subject to delivery. If the required size needs to be changed, it must be explained when ordering. Note: our company can design and manufacture on behalf of customers.
