Abstract

The invention relates to a digital temperature control type air cooler control device for a transformer. The control device comprises an air-cooled automatic control box and a temperature controller. A display device is arranged on a panel of the air-cooled automatic control box. An X-band microwave transmitter-2 (XMT-2) type digital temperature regulator is adopted as a master controller in the air-cooled automatic control box. The temperature controller acquires the temperature of upper-layer oil of a main transformer in real time through a temperature measurement resistor and a temperature measurement module, and transmits a starting control command or stopping control command to the master controller in the air-cooled automatic control box according to a switching value to start or stop a fan motor. Various running states of the cooler can be accurately controlled, various running and failure states of the oil temperature of the main transformer can be accurately monitored, the control device can communicate with a microcomputer to realize signal transmission, and a breakthrough in the conventional control mode is made.

Description

technical field [0001] The invention relates to a cooling control device, in particular to a digital temperature control transformer air cooler control device. Background technique [0002] Since the integration of supply and agriculture, a large number of rural substations newly received have a large number of old forced oil circulation air-cooled transformers. Most of these substations are distributed in remote towns, and the transformer load is greatly affected by seasonal and coastal tides. The temperature of the main body changes greatly within a day, so the requirements for the air cooler of the transformer are relatively high. In actual operation, it is found that the existing transformer cooling control device has the following problems: [0003] Problem 1: The original main transformer cooler control system adopts the winter and summer operation mode, and most of them are operated manually by the substation attendant according to the transformer oil temperature and...
