Secondary wiring diagram of parallel trains in the same period
Source: InternetPublisher:石榴姐 Keywords: Wiring diagram generator TV Updated: 2021/01/07
TV 1. TV z is a voltage transformer; KA is a voltage relay; KAi and KAz are intermediate relays;
KF is a differential cycle relay, which has two coils. When the voltage of the generator
to be paralleled is close to the voltage frequency of the operating generator (or power grid)
(±2.5%), the differential cycle relay
will act and send out a parallel signal; KMi is the
AC contactor to control the generator closing . The gate delivers power;
KMz is a DC contactor used to control
the magnetizing circuit of the generator .
