Abstract
The utility model discloses a draught fan automatic control loop system of a box-type station transformer of a transformer station. The draught fan automatic control loop system of a box-type station transformer of a transformer station comprises a temperature sensor, a main transformer, and a main transformer draught fan temperature controller. The main transformer is equipped with the temperature sensor which is connected with the main transformer draught fan temperature controller through a shielding signal cable. The temperature sensor acquires and sends oil temperature information of the main transformer to a data analyzing and processing control system center of the temperature controller to perform analysis processing on the acquired data so that program control to the draught fan of the main transformer according to the oil temperature change of the main transformer is achieved at last. If the value of the oil temperature of the main transformer is more than a set value, the draught fan of the main transformer is automatically started to operate. If the value of the oil temperature of the main transformer is less than the set value, the draught fan of the main transformer stops operating. Therefore, the station transformer is guaranteed to reliably operate within a specified temperature range.
