Inverseur Normal-Secours

 
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
 
Circuit-breaker withdrawable manually and equipped with :
-releaser STR
-release coil uppervoltage or undervoltage
-contact OF (1-2-3) indicating the position
-contact SD indicating fault-trip

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.
