In May,  SOROTEC  ushered in the 10th employee collective birthday party. We hope everyone can feel warmth and happiness by this activity. At 8:00 p.m. on the 24th,Our company held the may birthday party of the group headquarters in the conference room on the second floor.Twenty-six birthday workers and company leaders, well-wishers attended the party.The whole birthday party scene is beautiful, the food is rich and varied.All of this brought a special birthday blessing to them. Before the party, the company leader extended his sincere greetings to them, and wish them career progress, happy life.The management reform of the group is recognized, and such activities should continue thereafter. A cake symbolizes a united collective, a candle symbolizes a hot heart, because of the collective heart became wonderful, because of the heart collective became proud. When the Happy birthday song rang ,the familiar and wonderful melody sounded. Light the birthday candles ,along w...

On June 5, the SNEC 2019 PV POWER EXPO came to a successful conclusion.”Global green energy and photovoltaic financial summit” will bring together senior experts and stakeholders of photovoltaic industry to discuss and deal with challenges and opportunities of industry development.The global photovoltaic industry, especially in China, is developing rapidly and the market is growing significantly.The integration of household photovoltaic, distributed photovoltaic, energy storage, big data + artificial intelligence, smart energy micro grid, Internet of things and other industries is getting closer.The rapid growth of the renewable energy industry has also created a huge demand for capital.Innovation green finance, adapt to the new trend of development to become a new topic of industry development.In order to adapt to the new trend of finance, new energy and Internet digitization, the conference will explore how to integrate the three major elements of finance, new energy and energy Inter...

Switching power supply  is to use electronic switching devices (such as transistors, field effect transistors, thyristors, etc.) to make electronic switching devices “turn on” and “turn off” continuously through control circuits, so that electronic switching devices can modulate the input voltage, thus realizing DC/AC, DC/DC voltage conversion, as well as adjustable and automatic voltage stabilization of the output voltage. There are generally three modes of switching power supply: fixed frequency and pulse width mode, fixed frequency and variable pulse width mode, and variable frequency and pulse width mode. The former mode is mostly used in DC/AC  inverters  or DC/DC voltage conversion, while the latter two modes are mostly used in switching regulated power supply. In addition, the output voltage of switching power supply also has three working modes: direct output voltage mode, average output voltage mode and amplitude output voltage mode. Similarly, the former is m...

Nowadays, many people like to talk about “power quality”. There are many products of power quality, such as  SVG ,  APF and three-phase unbalanced regulator, which have become “hot-selling products”. But what are the benefits of improving power quality for people? Improving power quality is of great significance to the safe and economic operation of power grid, ensuring the quality of industrial products and the normal conduct of scientific experiments, and reducing energy consumption. Power quality is directly related to the overall benefits of the national economy. Good power quality is undoubtedly beneficial to the operation of electrical equipment, but the adverse impact of poor power quality on the operation of power system has not attracted enough attention. From the point of view of harm degree, the harm of some power quality problems is destructive. For example, the overvoltage caused by harmonic resonance in lightning impulse, capacitor and cable switching ofte...

In the fault area of the  outdoor cabinet , the cabinet is usually made of cold rolled steel or alloy, which is used to store computer and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, arrange equipment in an orderly and orderly manner, and facilitate the maintenance of equipment in the future. Cabinet is generally divided into server cabinet, network cabinet, console cabinet and so on. As the user of cabinet, you must know the fault area of cabinet. Fault area 1: below the cabinet (outside the cabinet) The area below the rack and above the floor is difficult to manage because leveling bolts or casters vary in size and manufacturer and height. There will be a lot of uncontrolled air in this area. If the area can be properly sealed, it can produce very high benefits. Usually, there is no solid baffle under the cabinet due to the need to connect wires or nets. This will also lead to air leakage in the area, bec...

With the progress of power electronics technology and control technology, domestic  active harmonic filter  has replaced imported products in various major projects. In 2012 alone, the sales of domestic APF products have exceeded the imported brands by five times. Active power filter will eventually replace the traditional passive filter because of its huge technological advantages, powerful functions and declining price. During the development of APF, modular APF equipment has gradually replaced traditional cabinet APF with its advantages of small size, convenient installation, high integration, stable operation and convenient expansion. In the next five years, the combination of modular APF and  static var generator  (SVG) will become the most powerful solution in power quality industry, and will be widely recognized by the market. Three-phase Balance Active Harmonic Filter(AHF) Meeting users’ requirements: – PF=0.99 and THDi < 5% – Compensation for 2- ...
