Problems solved by technology

[0002] In the daily maintenance of the substation, it is an essential task to detect the wind direction of the radiator of the transformer. The radiator of the transformer includes multiple fans of the main transformer cooler. Requirements, the wrong wind direction will affect the heat dissipation effect. In general operations, the switch of the main transformer cooler fan to be detected will be integrated into one or two main power switches. Therefore, when detecting the wind direction of the main transformer cooler fan , there will be at least 4 to 8 fans starting at the same time, the wind under the fans is strong and the airflow is very turbulent, it is difficult for the operator to determine the wind direction of each fan by perception, if using paper or other tools that can swing with the wind to test the wind direction and there is paper It is involved in the fan, crushed and stuck into the gap, causing the risk of fan blade jamming, and the road in the transformer area is paved with cobblestone roads for unloading oil. When the paper is involved, it is easy to drive the workers, causing damage to personnel and equipment.
Due to the strong wind and turbulent airflow below the fan, it is difficult for the traditional wind direction sensor using the wind vane structure to detect the wind direction of the main transformer cooler fan

Embodiment 1

[0028] In the operation and maintenance of the substation, the maintenance of the radiator of the transformer is essential. The fan of the main transformer cooler in the radiator has a specific direction of rotation according to the work requirements. It may be necessary to replace one of the radiators during routine maintenance. or multiple main transformer cooler fans, if the main transformer cooler fan reverses, it will affect the heat dissipation effect of the radiator, and even affect the working stability of the transformer. Therefore, it is necessary to detect the rotation direction of the main transformer cooler fan during routine maintenance , during general operations, the staff will integrate the switch of the main transformer cooler fan to be detected into one or two main power switches. Therefore, when detecting the wind direction of the main transformer cooler fan, there will be at least 4 to 8 fans start at the same time, the airflow below the fans is very turbul...

Embodiment 2

[0038] The present invention provides a wind direction detection device. The difference between the wind direction detection device in this embodiment and the wind direction detection device in Embodiment 1 is:

[0039] In this embodiment, the housing 7 of the wind direction detection device is provided with a limit column, which faces the top of the fan 6, and the length of the limit column can limit the fan 6 between the limit column and the fan socket 2, avoiding The fan 6 escapes from the fan receiving seat 2 under the action of wind force, which makes the wind direction detection device invalid.

[0040] The limit post provided in this embodiment can effectively limit the moving distance of the fan 6, ensure the working stability of the wind direction detection device, and avoid failure of the wind direction detection device.

Abstract

The invention relates to the technical field of wind direction detection, and particularly discloses a wind direction detection device. The device comprises a fixing plate and a fan, wherein the fixing plate is used for installing a power source, a fan bearing seat and an alarm device; the power source, the fan bearing seat and the alarm device are connected in series and form a galvanic circle; the fan bearing seat is used for being connected with the fan; the fan bearing seat is provided with two first conductive interfaces; the two first conductive interfaces are disconnected; the fan is in threaded connection with the fan bearing seat; the fan rotates under the action of wind power to drive a second conductive interface on a base of the fan to be close to or away from the first conductive interfaces; when the first conductive interfaces are in contact with the second conductive interface, the galvanic circle is switched on, the alarm device gives an alarm, and a main transformer cooler fan is detected to rotate reversely and needs to be maintained; and when the second conductive interface is far away from the first conductive interfaces, the galvanic circle is not conducted, the alarm device does not give an alarm, and the main transformer cooler fan is detected to rotate forwards without maintenance.
