The temperature of dry transformer is generally set at what degree
Consultation: I have a 1000KVA thermal insulation class F general temperature controller set at what degree to start? The staff of Runsheng transformer manufacturer told us:
1. Three-phase temperature patrol display: the three-phase temperature values of A, B and C are displayed every 2 seconds, and the ranking of the temperature values of each phase is displayed actively.
2. Multiple developing methods: The maximum method can actively display the maximum temperature value and phase sequence; Arbitrary one phase temperature fast switching appearance and deterministic appearance; The maximum temperature memory display can show the maximum value previously reached by one phase prior to the present time.
3. Fan start and stop operation: when the maximum temperature value is higher than or lower than the set value of fan start and stop, the fan control contact will be closed or disconnected with the indicator light indicating the state.
4. Overtemperature alarm: When the maximum temperature value is greater than the set value of overtemperature alarm, sound and light alarm will be conducted, and the output contact of the alarm will be closed for the user to connect the secondary alarm circuit.
5. Overtemperature tripping: when the maximum temperature value is greater than the overtemperature set value, the tripping alarm light will be on and the tripping output contact will be closed for the user to connect the tripping control circuit.
6. Fault alarm: when the Pt100 sensor and lead wire in the transformer A, B and C are broken or short, the fault light will be on and the alarm output contact will be closed for the user to connect the fault treatment circuit.
