Embodiment Construction

[0022] As shown in the figure, the concrete steps of the present invention are as follows:

[0023] 1. Arrange the wind direction ball device 2 above the power transformer 1 at a distance of 10-15 cm from the top surface of the power transformer 1. The wind direction ball device 2 includes a square box 201 with a side length of 30-50 cm, and each facade is provided with a ventilation hole 202. A plastic ball 203 with a diameter of 10cm, a distance of 1-3cm from the bottom, and a mass of 100g is vertically hoisted in the center of the top surface (refer to the "Typhoon Business and Service Regulations" issued by the China Meteorological Administration in 2001, and the minimum wind speed of level 5 can be used freely. The quality of swing is a reference), on the four facades of the square box body 201, the motion track positions corresponding to the plastic ball 203 are respectively installed with collision sensors 204, after the plastic ball 203 collides with the collision senso...

Abstract

The invention discloses a power system transformer auxiliary air-cooling method with induced current serving as a basis. The method comprises the steps of using data of a wind direction ball device which is arranged at the top of a transformer and induced current detectors which are arranged around the transformer as a criteria, using fans which are arranged at the periphery of the transformer asa cooling means, uniformly conducting air cooling on the transformer, and installing four temperature sensors in the centers of four vertical faces of the power transformer respectively; installing acontrol box in the direction, close to a master control building, beside the power transformer, regarding the direction with the longest contact time as the fan starting direction, setting rated poweroutput for the fans in the direction, setting 50% rated power output for the fans in other directions, and when the output time is zero, regarding the four directions all regarded as the fan startingdirection, and setting set 50% rated power output for all the fans; when the temperatures of four temperature sensors are lower than 38 DEG C simultaneously, using a controller to automatically closethe fans on four arc tracks.

Description

technical field [0001] The invention relates to a method for cooling a transformer, in particular to an auxiliary air-cooling method for a power system transformer using induced current as a criterion. Background technique [0002] The power transformer is an important equipment in the power system. Its operation mode is complex, and the heat dissipation is large and uneven during operation. A single heat dissipation method cannot meet the increasing load requirements of power users. At present, power transformers generally adopt cooling methods such as air cooling and water cooling, and the cooling method is relatively simple. When the power transformer cooling system breaks down or the cooling is uneven, it is very easy to break down, shorten the service life, cause the power transformer to stop operating, make the power user lose the power supply, and bring economic and image loss to the power company. Contents of the invention [0003] The present invention proposes a...
