🔥 آتش گرفتن گاز جمع شده در رله بوخهلتس پس از تریپ رله
⚠️ اگر این گاز آتش بگیرد به معنای وجود خطای جدی در ترانسفورماتور است و نباید آن را مجدد برقدار کرد.
🔥 Igniting the gas accumulated in the Buchholts relay after tripping the relay
⚠️ If this gas catches fire, it means there is a serious fault in the transformer and it should not be re-energized.

U1 U2 I recharge
This recharge is used mainly for Ni-Cd batteries. During the recharge a boost charge of approx. 125% is provided, to compensate the losses in discharge and recharge of the battery (estimated in approx. 25%). The recharge works as follows:
If the mains fails for a time which is longer than the programmable threshold, when the mains returns the output voltage of the RTB.e is taken to a higher level than the floating, called boost charge and a safety timer is activated.
If the recharging voltage doesn’t exceed the programmed crossing threshold,
normally a certain percent of the floating, the voltage is maintained and a first phase of boost charge starts, in which the current is constant and the voltage is increasing.
After a certain time the recharging voltage reaches the programmed level for the second phase of boost charge; a timer is started and the battery is kept under boost charge conditions for the time programmed. After this time has elapsed the output voltage of the RTB.e is brought back to the floating value. If this does not happen within the maximum programmed time, the safety timer intervenes and the voltage is forced to floating. This event generates an alarm.
During the boost charge it is possible to enable the voltage-drop compensation
function. Setting the desired compensation constant at full load (in percent of the nominal voltage, with 0,1% steps, from 0% to 5%) the RTB.e will adapt the output voltage on the basis of the current supplied

Automatic recharge of the battery
When selected the RTB.e recharges the battery automatically, according to the predefined modalities. The recharging cycle begins consequently according to one of
the following events (which are programmable):
Mains failure for a longer period than the programmed value Intervention of the current threshold or Intervention of the voltage threshold.
The predefined cycles can be programmed in the Menu Parameters

Recharge IU according to the DIN 41773 standard
The recharge undergoes to phases:
Phase 1: the current is constant and the voltage increases.
Phase 2: the current decreases and the voltage is constant.
When the recharging current goes below a certain value the battery is assumed fully recharged and the cycle ends. Consequently the output voltage is set at the floating level. During the floating the battery voltage is controlled as minimum value in order to avoid undesirable discharges, and towards as maximum value in order to avoid excessive heating of the electrolyte. The “thermal compensation” of the floating voltage in function of the battery temperature can be added as an option
