Detailed Description

Automatic Transfer Switch YEQ2 Series MCCB Annex (Supplementary the police contact), the mechanical interlocking transmission, intelligent controller and other components. It has the integral style and split type two kinds mechanism. Integral controller is equipped with a base and executing agencies; Split type is intelligent controller installed in the panel , installed user base by implementing agencies to install the counter body controller with the implementing agencies with about 2m long cables. The body of the intelligent system consists of such accessories as dedicated positive/negative electromotor, breaker, fire control tripping, mechanical interlocking, aviation plug and connector terminal. All components are installed on the same metal sheet. The intelligent system (400VAC 50/60Hz working voltage) is provided with the function of mechanical-electrical interlock protection to guarantee safe and reliable power supply for you. Functions: 1. The automatic controller can measure the voltages of both circuits at the same time. When the supply voltage is higher than 115% of the rated value, it judges as over voltage; when it is lower than 60% ~ 80% (preset by user) of the rated voltage, it judges as under voltage. The microcomputer judges and processes the measuring results and then sends out corresponding orders as switch-off, switch-on,generation, unloading and alarming. The above measuring results display on the controller panel and can also be connected with the computer by the serial port for the user to find reasons. The intelligent controller is available for three functions: self-input and self-restoring applicable between power grid and power grid; self-input without self-restoring applicable between power grid and power grid; and self-input and self-restoring applicable between power grid and generation. 2. Self-input and self-restoring (R) applicable between power grid and power grid.The default for initial electrifying is normal power supply. When the normal power supply (N) is abnormal, the normal power supply (N) switches off automatically to the critical level after switch-off time delay. Then it switches automatically to the reserve supply (R) after switch-on time delay. 3. The delay time can be set from 0 - 30s. 4. Self-input without self-restoring applicable between power grid and power grid
