| Normal-Emergency supply switching version 1 |
| -Control of the voltage on the Normal supply and switching on Emergency automatically in case of losing the Normal supply. |
| -Priority to the Normal supply |
| -Auto switching on the Emergency supply without additional control on the Emergency supply. |
| |
| Working detail of the switching |
| The relay K1 control the presence, the lose of phase , min or max voltage on the Normal supply circuitry. In belgium, we use frequently the relay V661 from the company AUTOMATION, but you can find equivalent type on the market. |
| When K1 detect a fault on the Normal supply, it is deenergised and break the supply of the relay K2T. |
| The contacts 13-14 and 33-34 of this relay let fall the coil of the contactor KM1 (Normal net), whereas the contacts 21-22 let the coil of the contactor KM1S be energised. The 2 contactors KM1 and KM1S are mechanicaly interlocked and also electricaly with the auxiliary contact 21-22. |
| To prevent that this system goes on and off without ending with a too fast switching, the relay K1 has to be set with a sufficent hysteresis time. |
| If the relay K1 doesn't have the possibility of setting an hysteresis time, we have to include a time-relay in the circuitry of the relay K2T |

| 1. Sample of drawings (10.5Mb) |
| 2. Overview of the drawings : zip version (1.5Mb) or dwg version (8Mb) for printing these pages, is it better to make a script for the 63 folios of the drawing. Here you have the script that I use, compatible with Autocad 2005. Yet a remark : the English version is under the ENGLISH Layer (hard to find isn't it !). The two others languages have to be off, it is FRANCAIS and NEDERLANDS. |
