The basic principle of static switch circuit diagram

Published:2014/2/19 21:02:00 Author: | Keyword: The basic principle of static switch circuit diagram,

The effect of static switch: two ac power frequency and amplitude are just can work in parallel at the same time. When an ac power failure occurs, will produce a balance between the two power supply current, so that the change of two parallel power supply output voltage, affect the reliability of power supply. Static switch is used to cut off the power source of the failure of the output, achieve the inverter output and uninterrupted switch between the mains bypass output. For less than 2 kva on-line UPS power supply, the inverter output and mains bypass output q switch, USES fast relay as switching elements, mostly because of the switching time is only 2 ~ 5 ms, ms to fit the needs of communication equipment for power don't interrupt. For capacity in more than 2 kva UPS power supply, due to the relay working current increases, the switch time will increase to 80 ms to 120 ms, and snap relay instant sparks will produce high temperature and damage the contact, or often opened in electric arc is formed between the normally closed contacts and will have a instantaneous short circuit, two ac power, so relay used in switching is limited to small capacity of UPS power supply. Ac double contactor with interlock properties, although can control the output power larger UPS power supply, but the switch time has more than 10 milliseconds.   (View)

UPS power inverter based on combination can be divided into the transformation type and model, set up the static switch type single phase transformation of UPS power main circuit diagram as shown. The figure shows that when the mains is normal, for the inverter output as the main power supply load. In order to facilitate maintenance, set up a manual maintenance bypass switch, namely access to bypass switch S, closed, and then make the S2, S3 and static switch. Under standby power supply power to the load, the UPS system away from the bypass system, which can do maintenance of inverter, static switch. When the inverter as primary power supply, first close the static switch and the bypass switch S2, S3, and then disconnect S1.   (View)
