The basic principle of static switch

Published:2011/4/7 22:10:00 Author:may | Keyword: static switch

The usage of static switch: it can parallel normal work only when two AC power supply has the same frequency, amplitude. When one AC power supply go wrong, will generate restoring current between the two power supply, thereby make changes of output voltage in two parallel power supply, it will influence the reliable of power supply. The usage of static switch is cut the error power supply to output, and accomplish unbroken switchover between inverter output and commercial power bypass output. We mostly adopts high-speed relay as switching device, because its switching time only has 2ms~5ms, is fit for the requirement of communication equipment needing power supply without interruption. In the case of UPS power supply with capacity above 2KVA, because the increase of relay working current, its switching time will add to 80ms~120ms, and sparkle generated in the moment relay snapping will cause high temperature to damage the contact point, or voltaic arc generated between normal open and normal close contact point will short circuit the two AC power supply in a moment, so relay using for switching is only limit to low capacity UPS power supply, but its switching time has tens seconds.   (View)

Human body induction alarm circuit diagram

Published:2011/4/6 21:56:00 Author:Rebekka | Keyword: Human body induction, Alarm circuit

The alarm circuit is a alarm device that makes use of the distributed capacitance of the human body and to work. The multivibrator type oscillator composed of BG1, L1, C1 works but the relay does not before a human body access the alarm; When a human body access the alarm, the periodic circuit will stop work and the alarm will work because of the capacitance of human body.   (View)
