It is very important to classify high-voltage DC regulated power supplies and choose applications purposefully.

High-voltage DC regulated power supply, also known as DC high-voltage power supply, is a switching power supply that is input by AC voltage or three-phase power and has an AC voltage output of thousands of volts or hundreds of thousands of volts. It can achieve hundreds of watts or several kW, and can realize voltage regulator tube or steady flow.

The characteristics of high-voltage DC stabilized power supply are small volume, relatively light weight, high output power, relatively small ripple, low energy storage technology, high stability and reliability, and are currently used A more common current flow.

There are three main categories of recommended high-voltage DC power supplies:
1. High-voltage distributed DC power supply: It is a new type of DC power supply equipment, mainly used in small switch stations and user terminals, which can provide more reliable and uninterrupted working power for secondary control lines, and can also provide power for devices that meet the requirements. The required primary switchgear provides DC operating power.

2. Wall-mounted DC power supply: This power supply is suitable for small switch stations, small user substations and small 10kv substation systems. It has the advantages of small size, simple structure, and independent system composition. It is also one of the most widely used DC power supplies at present. .

3. Micro DC operating power supply: This power supply is mainly used in substations, switching stations, ring network cabinets and box-type substations for vacuum circuit breakers, vacuum contactors, load switches and other equipment as well as some secondary controls. Protection and signal circuits provide reliable DC power.

In the process of use, we need to choose a high-voltage DC power supply according to our own purpose, so that we can find a more suitable switching power supply, provide stable voltage and current, and induce electrification. should be treated with caution.


"Key components of modern power systems: the role of dry-type power transformers"

As a key component in modern power systems, dry-type power transformers not only meet the energy conversion needs of the power system, but also meet the requirements of environmental protection and safety. In the future, with the advancement of technology and the expansion of application scope, dry-type power transformers will play a more important role in the power industry and bring more efficient, stable, and environmentally friendly power services to people.

What should I do if the transformer suddenly short-circuits? Do you know these reasons?

To deal with transformer short-circuit accidents in daily operations, it is necessary to find out the essence of the problem through inspection and testing. When the transformer suffers from a sudden short circuit, both the high and low voltage sides will be subject to a large short-circuit current. In the short time before the circuit breaker can be disconnected, the short-circuit current will generate an electromotive force proportional to the square of the current that will act on the winding of the transformer. Electrodynamic force can be divided into radial force and axial force.

How much kW power consumption can a 1000kVA transformer withstand?

KVA (kilovolt-ampere) is the unit of apparent power, and KW (kilowatt) is the unit of active power. In addition to apparent power and active power, there is also reactive power, and the unit of reactive power is Kvar (kilovar).

High voltage test of power transformer - a full set of knowledge in detail!

In order to ensure the accuracy and authenticity of the high-voltage test results of power transformers, the test content must be reasonably selected in strict accordance with relevant regulations. The content of high voltage test of power transformer mainly includes: measurement of insulation resistance, measurement of leakage current, dielectric loss factor test, AC withstand voltage test, etc., the following is a specific introduction. In the high voltage test of power transformer

The main protection and backup protection of power transformers, all the knowledge is explained!

The abnormal conditions of the transformer mainly include overload, lower oil level, overcurrent caused by external short circuit, high oil temperature of the transformer in operation, high winding temperature, high transformer pressure, and cooling system failure. When the transformer is in an abnormal operating state, an alarm signal should be given.

High-frequency air oxidation switching power supply completes high-current output

Design scheme of frequency air oxidation switching power supply. Because the output waveform is a waveform, it is beneficial to improve the sealing quality, reduce the melting of the film caused by the temperature rise, prevent the expansion of the pores of the air oxide film, improve the strength and relative density of the air oxide layer, improve product quality, and improve product quality. out rate.
