Fast transfer electro-mechanical relay |
摘要 |
This invention provides an electromechanical transfer switch having a transfer time sufficiently fast, less than 20 milliseconds, as to allow computer based equipment to ride through a power interruption without shutdown. The transfer switch utilizes relatively slow acting, high amperage, electromechanical power relays that have been modified by replacing the relay armature spring with a higher tension substitute and applying overdrive voltage to the relays. |

1. A method for enhancing the performance of a relatively slow acting, high amperage electromechanical power relay to achieve transfer times sufficiently rapid to serve as a transfer relay for use with computer based equipment to automatically switch from a primary power source to a secondary power source without computer shutdown upon interruption or failure of the primary source, comprising;
providing a conventional electromechanical power relay, said relay having a coil and transformer means to apply a voltage to the coil, thereby activating the relay by movement of an armature working against an armature return spring; replacing the armature return spring with a spring having a sufficiently greater spring tension to accelerate relay dropout; and modifying the transformer means so as to apply a higher overdrive voltage to the coil to accelerate relay pickup, said replacement spring tension and overdrive voltage selected to achieve transfer times of less than 20 milliseconds. |
