Automatic voltage regulator TFXT-2Detailed description of (AVR):
TFXT-2 automatic voltage regulator (AVR) is the latest automatic voltage regulator developed by Lanzhou Lanzhou electric motor Limited by Share Ltd. It is suitable for TZH series generators, TZHW and TFXW series generators.
When the rated speed and the rated voltage of the AVR are unloaded, the sudden load and sudden discharge of 60% of the rated current and the power factor of no more than 0.4 (lag) of the three-phase symmetrical load are observed. When the voltage drops, the transient voltage regulation rate should be no more than 15%. When the voltage rises, the transient voltage regulation rate is no more than 20%, and the voltage recovery time is not more than 1S.
Main technical data:
1.1 rated voltage: 400V;
1.2 maximum allowable shunt 8A;
The maximum allowable peak voltage of 300V is 1.3E1---21, and the maximum allowable average voltage is 133V.
Main technical indexes
2.1 steady state voltage adjustment rate: less than 1%
2.2 the setting range of no load voltage is 95%-105% of rated voltage
Use environmental elevation: no more than 2000M environmental temperature: -20, --55 C
