Introduction of pure sine wave inverter in high quality power supply system

Pure sine wave inverter power is designed for power plant, substation, telecom industry, automation control equipment, solar energy, oil field, wind energy and so on. It is mainly used in the place where the load equipment requires high quality of the power supply. Such as electric power telecontrol, RTU, power carrier, monitoring, program control switch, computer room, network, billing, server and accident light place and so on. If the AC input is cut off, the power supply will be provided by the power system, post office system’s DC screen or external battery cabinet through the inverter, will provide a long and continuous power supply for the load equipment. If the DC screen is broken down, the inverter is overloaded of failed, the system automatically switches to the bypass power supply, which ensures the continuity. In a place with DC power, the inverter power supply is used to supply the important load equipment with the following advantages:
1.Avoid the repeated investment of the battery group, reduce the maintenance of the system, and reduce the operating cost of the system
2.The DC screen of power system usually adopts VRLA battery. Because DC screen has high reliability and long life (10~15 years), the reliability and life of DC screen can be greatly improved. The battery in the conventional UPS often has no maintenance and no monitoring, it is easy to appear in the case that the battery has long been damaged but can not be found in time.
3.Because of the large capacity of the DC screen, it can provide a long enough AC power supply time after the power grid is cut off.
Lightning protection system: the damage caused by lightning strikes is common, and there are numerous losses to the production. In order to reduce the losses caused by lightning, the power supply system should be equipped with an advanced lightning protection unit, which effectively prevents lightning from damaging the equipment. The input circuit can effectively, reliably and quickly absorb the pulse voltage of the input terminal, so as to ensure that the output power equipment is not affected.
AC and DC isolation inverter technology: DC system uses high frequency and high efficiency DC isolation converter, so that the input and output electrical is isolated, effectively prevent electric shock accidents, make the DC system grounding problem very simple, and the second grounding is more convenient. The active filter technology used in DC greatly reduces the noise of the system and improves the input voltage of the DC system. The DC/DC high frequency isolation converter is connected to the inverter with high voltage and APFC high voltage in parallel. So when the power supply is normal, the inverter is supplied by AC rectifier and the DC is in the state of hot backup. When the power interruption or abnormal AC input, protect the normal startup, DC isolated by the DC/DC transform to the inverter power supply, inverter into 220V sine wave output voltage, so whether it is normal or not, the power supply system is through the inverter power supply to the load, so it is always the output AC voltage and frequency stabilization the voltage of 220V, realize the uninterrupted work.
Sinusoidal pulse width modulation technology: the whole machine adopts the full high-frequency design, which has the advantages of strong anti-interference ability, high precision, high frequency stability, small distortion, high efficiency, small volume and light weight. The inverter main circuit uses advanced PWM and three way overcurrent detection technology, which greatly improves the reliability of inverter and makes the instantaneous load controllable due to nonlinear load, and has good output protection characteristics.
Remote monitoring: with remote monitoring signal output, the real-time operation state of the inverter (DC input, AC input, inverter operation and fault signal) can be sent to the control center through the switch input port of the data acquisition system.
Hot standby system: any 2 /3 stations can be barred into 2+1 or 3+1 hot backup system, the built-in automatic connection program, any one barge connection output, it is more convenient to press according to the installation, and the system is more reliable.
Aseismic design: the system adopts seismic design, which greatly improves the adaptability of long distance transportation and vehicle system, and effectively reduces the damage probability.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

How to maximize the efficiency of your UPS

1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...
