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.
