Embodiment Construction

[0021] The control method and device of the transformer cooling system provided by the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0022] see image 3 , is a control circuit diagram of an embodiment of the present invention, and the transformer cooling system includes a submersible oil pump, a fan and an intelligent control device. The method of the invention comprises the following steps: operating the submersible oil pump of the working group of the cooling system of the transformer; and determining the number of cooling fans to be put in according to the oil temperature of the transformer.

[0023] The submersible oil pump of the working group of the present invention operates first, and the radiator is fully utilized to cool the transformer oil. According to the oil temperature change of the transformer, the number of fan motors is controlled separately to ensure the continuous and smooth adjustment of the t...

Abstract

The invention discloses a method and a device for controlling a transformer cooling system. The system comprises a transformer submersible pump, fans and an intelligent control device. The method comprises the following steps of: (a) operating the submersible pump of a working group of the transformer cooling system; and (b) determining the number of input fans according to the oil temperature of a transformer. The method and the device for controlling the transformer cooling system can adapt to the changes of ambient temperatures in different seasons; and by the method and the device, the temperature of the transformer can be effectively adjusted, the energy consumption of a cooling fan motor can be reduced, energy conservation and consumption reduction can be realized and the cooling system can be operated optimally.

Description

technical field [0001] The invention belongs to the field of transformer cooling system control, and in particular relates to a control method and device for a transformer cooling system. Background technique [0002] For transformers cooled by forced oil circulation air, cooling devices with different capacities are configured according to the capacity of the transformer. Cooling units are divided into standby, auxiliary, and working groups according to the functions used. Generally, there is one set of cooling device for each transformer equipment (it can be put into operation automatically when the working cooler fails), and one set of auxiliary cooling device (transformer load current is greater than 70% of the rated current or the upper oil temperature is higher than a certain It will be automatically put into operation when the value is set), and the rest are working cooling devices. Each cooling device consists of a submersible pump and 2 to 3 fans. [0003] When e...
