1. Product Introduction
1.1 Product Description
Considering that accidents and damages in the power grid occur unexpectedly and suddenly, and also lead to unpredictable consequences, it has always been relevant to provide consumers with an uninterrupted supply of electricity. Mobile devices for "automatic input of backup power" provide a positive effect of application for uninterrupted power supply of facilities. To transfer consumers from one line to another, a certain sequence of switching operations is required, otherwise accidents are expected to occur, leading to accidents. The timely execution of switching operations is entrusted to the "automatic input" backup power of electricity. When using the "automatic transfer switch" device, it is possible to ensure that consumers are automatically transferred from one line to another when the voltage disappears. The operator does not need to transfer consumers from one line to another, thus preventing accidents related to erroneous switching by the on-duty personnel.
1.2 Product Features
The "automatic input" reserve device for electricity uses electromechanical relays and semiconductor thyristors. Here, the voltage loss signal is generated using an electromechanical relay and transmitted to the control electrode of the thyristor. At the same time, a turn-on signal is generated by the electromechanical relay of the backup line and the control electrode of the thyristor corresponding to that line is transmitted.
"Study of the Operation of Automatic Reserve Input" is the key execution engine to achieve high availability and fault tolerance of the system.
