Post of remote control PDKS
Post of remote control and alarm system PDKS it is intended for connection to the tire of data transmission of the isolation control block (ICB) in dividing transformers of the TPO and TPT series and the alarm system by means of "dry" contacts about a condition of isolation of an output chain, temperature of transformers and power of loading.
PDKS is executed in the plastic case with extent of protection of IP20 for installation in an electrocase or directly in a transformer case on a DIN lath.
Algorithm of work of a post
- During the normal operation of the transformer contacts of alarm relays "R", "t °" and "P" are opened.
- At decrease in level of isolation less than 50 kOhm in 5-7 sec will join the alarm R relay. At restoration of level of isolation there is an automatic return of the alarm R relay to an initial state.
- At a transformer overheat (Т> 75 °C) will join the alarm t ° relay. At decrease in temperature (Т< 65 °C) occur automatic return of the alarm t ° relay to an initial state.
- At excess of 101% of loading the alarm P relay will turn on. At decrease in loading (Р< 100%) - automatic return of the alarm P relay to an initial state.
