DC high voltage power supply
DC high voltage power supply

High-voltage DC power supply is also called DC high-voltage power supply . It is a power supply with AC mains or three-phase power input and DC voltage output of thousands of volts or more than tens of thousands of volts. Steady flow. In the earlier DC high-voltage power supply, the AC mains or three-phase power was boosted from a high-frequency power transformer to AC high-voltage power, and then rectified and filtered 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.

Features

Its characteristics are small size, light weight, high efficiency, high power, small ripple, low energy storage, high stability and high reliability.

In order to meet the requirements of different uses, some DC high voltage power supplies are made in the form of automatic conversion of stabilized current.

High-voltage distributed DC high-voltage power supply

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

Wall-mounted DC power supply

Wall-mounted DC power supply is suitable for small switch stations, small user substations, and small 10KV substation systems. It adopts an integrated design concept and consists of rectifier modules, monitoring modules, step-down units, power distribution units, and battery installation boxes. Constitute the system and other characteristics; the monitoring module adopts LCD Chinese character menu display, which is perfect for system monitoring and battery automation management. It has four remote interfaces for connection with the automation system. It provides two communication interface options of RS232 and RS485. It provides three types of RTU, CDT and MODBUS. Communication protocol selection.

Micro DC Power Supply

Miniature DC operating power supplies are mainly used in substations, switchgear, ring network cabinets and box-type substations. They are primary switching equipment (vacuum circuit breakers, vacuum contactors, load switches, etc.) and secondary control, protection and signal circuits ( (Such as microcomputer protection, remote control unit RTU, load control device, indicator lights, analog indicators, smart meters, etc.) to provide reliable DC high-voltage power .
