Non-woven meltblown electrostatic electret generator dedicated high-voltage power supply technology details

Non-woven electrostatic electret machine, commonly known as non-woven fabric plus static equipment, electrostatically filtered air filter material, using electrostatic force to capture dust particles, non-woven fabric treated by electret, because it has persistent static electricity, can It captures fine dust by electrostatic effect, so it has the characteristics of high filtration efficiency and low filtration resistance. Low wind resistance, high efficiency and high dust holding capacity. Represented by the "static air filter", a breakthrough static-carrying filter material is used to effectively block particulate pollutants greater than 0.1 microns in the air, such as dust, hair dust, pollen, bacteria, etc., while ultra-low impedance ensures energy saving. In addition, the deep dust-holding design ensures a longer service life.

Due to the fact that discharge and ignition are prone to occur during the operation of the equipment, the traditional high-voltage power supply may break down the non-woven fabric during discharge, resulting in holes that are visible to the naked eye; and the restart time of the arc protection of the high-voltage power supply will affect the non-woven fabric charged. Uniformity, causing some products to fail to charge. The DC high-voltage power supply has been specially improved for this application and properly solved the above problems. The DC high-voltage power supply has small energy storage and will not cause damage to the non-woven fabric during discharge and ignition; the nanosecond arc-drawing response capability ensures that the power supply is quickly restarted within 20ms, so that the charging effect is even.

The early DC high-voltage power supply was to convert AC mains or three-phase power from an industrial frequency high-voltage transformer to AC high-voltage power, and then rectify and filter to obtain DC high-voltage power. Due to the low frequency, the volume and weight of the power supply are relatively large, and the conversion efficiency and stability are poor. With the development and maturity of switching power supply technology, DC high-voltage power supplies developed using high-frequency switching conversion technology combined with the characteristics of high-voltage power supplies have become mainstream.

High-voltage distributed DC power supply

The high-voltage distributed DC high-voltage power supply is a new type of DC power supply equipment, which is mainly used in small switching stations and user terminals to provide reliable and uninterrupted secondary control lines (such as intelligent terminals such as microcomputer protection and indicator lights, analog indicators, etc.) Working power supply, to avoid the loss of protection of the microcomputer protection when the AC power is lost, and to solve the problem of microcomputer protection failure due to the failure of the UPS due to operating overvoltage and harmonics. At the same time, it can also provide DC operating power for primary switchgear (spring mechanism vacuum circuit breaker, permanent magnet mechanism vacuum circuit breaker, electric load switch, etc.) that meets the power requirements of the device.

Wall-mounted DC power supply

The wall-mounted DC power supply is suitable for small switching stations, small user substations and small 10KV substation systems. It adopts an integrated design concept and is composed of a rectifier module, a monitoring module, a buck unit, a power distribution unit, and a battery installation box; it has a small size, simple structure, and independent Features such as a system; the monitoring module uses LCD Chinese menu display, perfect for system monitoring and battery automation management, has four remote interfaces to the automation system, provides RS232 and RS485 two communication interface options, provides RTU, CDT, MODBUS three Communication protocol selection.
