Electrician TBJV represents what relay
This is used to control the relay in the control circuit in the high-voltage circuit breaker, which represents the anti-trip relay, because when the high-voltage switch, if the line is faulty (if the line has a short circuit), will protect the action trip, but As the switch signal is still not open, the circuit breaker will re-closing phenomenon, so the actual circuit will increase a anti-jump relay, when the switch after the first closing switch protection trip, this relay will be locked Close the circuit so that it can not be closed again
