Working Principles
The TRSD is a PACK-level thermal runaway suppression system for the ESS and
consists of the thermal runaway suppression box, PACK partition control valve,
PACK extinguishant port, extinguishant pipes, and auxiliary power supply and
distribution circuits.
The TRSD communicates with the ESS. When a thermal runaway alarm is
generated for any PACK, the ESS sends a fault signal and PACK location
information to the TRSD. After receiving the information, the TRSD starts to
release extinguishant into the PACK. The heat in the PACK is absorbed quickly by
the extinguishant to rapidly cool the PACK, thus suppress the thermal runaway
process.
